Consider a long train moving at speed v. Now consider a passenger throwing a ball inside this train, towards the back of the train, with same velocity v (but in the opposite direction of the train movement). 

- A passenger inside the train will see the ball moving with speed v
- For an observer outside the train, however, the ball will appear as still. In fact, for him the ball will have a speed v (given by the movement of the train) -v (velocity of the ball but moving in the opposite direction), so the net velocity will be v+(-v)=0.

Does a physicist studies cells and life cycles?

Answers

Hey there!

No, that would be a biologist. Biologists study biology, or life. They're focused on life cycles, cells, evolution, and so much more.

Physicists focus on physics. They learn about forces, motion, and the study of the universal forces like gravity, momentum, and speed. Just like mathematics, they study patterns and look for new discoveries to be found in the fields of science, physics, and even mathematics.

Hope this helps!

Final answer:

Physicists may delve into biological concepts through biophysics, but the study of cells and life cycles is principally a field within biology, focused on by cell biologists.

Explanation:

No, A physicist primarily studies the fundamental principles governing the universe, such as energy, force, and matter. While physics does impact biological systems by explaining behaviors of molecules in cells or assisting in the creation of medical technology, the study of cells and life cycles specifically falls within the realm of biology.

Cell biology is a branch of biology focusing on the study of cellular structures and functions and is fundamentally concerned with the life cycle of cells. Physicists may contribute to this field through biophysics or biomedical applications, such as using physics principles to describe properties of cell membranes or developing diagnostic tools like MRI machines. However, the everyday work of studying cells and their life cycles is typically performed by biologists rather than physicists.

The mechanical advantage of a machine is always greater than 1. true or false

Answers

Final answer:

The statement is false; the mechanical advantage of a machine is not always greater than 1. It is the ratio of the output force to the input force and can be less than 1 in machines like third-class levers. However, machines like hydraulic systems with a wider output plunger can have a mechanical advantage greater than 1.

Explanation:

The statement that the mechanical advantage of a machine is always greater than 1 is false. The mechanical advantage (M.A.) is the number of times the input force is multiplied by a machine to achieve a greater output force. It's determined by the ratio of the output force to the input force.

In certain simple machines like levers, the mechanical advantage can indeed be less than 1. For example, in a third-class lever, where the effort arm is shorter than the load arm, the user must apply more effort than the load. This results in a mechanical advantage of less than 1. On the other hand, when discussing hydraulic systems, if the output plunger is wider than the input plunger, the mechanical advantage is greater than 1 as the output force is bigger than the input force.

The efficiency of a machine, which is the ratio of output work to input work, is always less than 100 percent due to energy losses such as friction, which converts some of the work into heat. This is a separate but related concept reflecting the loss of useful work when operating a machine.

In conclusion, while many tools and machines are designed to give us a mechanical advantage, this advantage can either be greater or less than 1, depending on the design and function of the machine.

Newton concluded that some force had to act on the moon because

Answers

Think in gravity, the moon is orbiting the Earth because of gravitational pull/force. Without this gravitational pull, the moon will just move in a straight line (Newton's first law).

Newton concluded that some force had to act on the moon because it is constantly accelerating towards Earth.

Without such a force, according to Newton's First Law, the Moon would continue in a straight path instead of orbiting the Earth. In 1666, he recognized that this centripetal force was necessary to maintain the Moon's circular path. He also theorized that the gravitational force must be proportional to the masses of the Earth and the Moon and that it follows an inverse-square relationship with distance.

Newton's insight was that the same force that causes an apple to fall to the ground also keeps the Moon in orbit around the Earth. This led him to deduce the Law of Universal Gravitation. According to Newton's Second Law, the moon's acceleration towards Earth indicated a centripetal force, which he later defined in his Principia using his laws of motion and the newly formulated concept of gravitational force.

Furthermore, Newton discovered that the gravitational force between any two bodies not only follows the Universal Law of Gravitation but also forms an action-reaction pair, satisfying his Third Law of Motion. This was a crucial realization for Newton to fully explain the motion of the planets and the gravitational pull between the Earth and the Moon.

Hello there!

We need to use the formula for kinetic energy.

K.E = 0.5 * mv²

M represents the mass which is 60kg

V is the velocity which represents the speed of the moving which is 2 m/s

K.E  = 0.5 * 60 * 2²

K.E =  0.5 * 60 * 4

K.E = (30)(4)

K.E = 120

2. A 200-kg boulder has 39,200 joules of gravitational potential energy. What height is it at?


3. A 1-kg model airplane has 12.5 joules of kinetic energy and 98 joules of gravitational potential energy. What is its speed? What is its height?

Answers

We have that the gravitational energy is given by: U=mgh where m is the mass of the object (in kg), g is the gravitational acceleration and h is the height of the object (in meters). Hence, h=U/(m*g) where g=9.8 m/s^2. Thus, h=20 m if we substitute.
Similarly, substituting in b, we have that the height of the model plane is 10 m. The kinetic energy is given by: K=[tex] \frac{1}{2} *m*u^2[/tex] where u is the speed of the object. Hence, solving for u we have u=[tex] \sqrt{2K/m} [/tex]. Substituting, we have that u=5m/s.

As per the first question we have to calculate the height at which the boulder is present.

we have been given the mass of the boulder [m] as 200 kg.

The gravitational potential energy is given as 39,000 Joule.

The gravitational potential energy at a height ' h'  from the surface earth is given as P.E= mass×height×acceleration due to gravity

The value of g=9.8 m/s^2

   Hence height [h][tex]=\frac{P.E}{mg}[/tex]

                              =[tex]\frac{39000}{200*9.8} metre[/tex]

                              =19.8979 metre

As per the second question we have to calculate the sped and height of the model airplane.

the mass of model airplane is 1 kg

The kinetic energy [K.E] of the airplane is 12.5 joule

we have K.E[tex]=\frac{1}{2} mass*speed^2[/tex]

                K.E[tex]=\frac{1}{2}mv^2[/tex]

                 [tex]v^2=\frac{2K.E }{m}[/tex]

                  [tex]v^2=\frac{2*12.5}{1}[/tex]

                    [tex]v=\sqrt{25}[/tex]

                      v=5 m/s

Again we have to calculate the height [h]

The potential energy is given as 98 Joule.

we know that P.E= mgh

                        tex]h=\frac{P.E}{mg}[/tex]  

                       =[tex]\frac{98}{1*9.8} metre[/tex]

                       =10 metre

A college student holds a pail full of water by the handle and whirls it around in a vertical circle at a constant speed. the radius of this circle is 0.95 m. what is the minimum speed that the pail must have at the top of its circular motion if the water is not to spill out of the upside-down pail

Answers

Here we have a circular motion. In that type of motion two new forces appear: centrifugal and centripetal. Centrifugal force tries to move object away frome the center of rotation. Centripetal force is the reason why object moves in a circle.

According to Newton's first law, in order for water not to spill out total force acting on water must be equal to zero. Forces acting on the water are gravitational and centrifugal.
[tex]0= F_{g} + F_{c} \\ - [tex]F_{g} = F_{c} \\ m*g= \frac{m* v^{2} }{r} \\ g= \frac{ v^{2} }{r} \\ v^{2} =g*r \\ v= \sqrt{g*r} \\ v= \sqrt{9.81*0.95} \\ v= \sqrt{9.3195} \\ v=3.1 m/s[/tex] [/tex]

Forces have opposite signs as they act in opposite directions. But their value is the same so we can ignore signs:

a water-balloon launcher with mass 4 kg fires a 0.5 kg balloon with a velocity of 3 m/s to the east. what is the recoil velocity of the launcher?

M1 =  4 kg (mass of the water balloon launcher)
V1=?
M2= 0.5 kg ( mass of the balloon)
V2 = 3 m/s

Therefore; 4 V1 = 0.5 × 3
                   4V1= 1.5

A 150 kg hoop rolls along a horizontal floor so that the hoop's center of mass has a speed of 0.130 m/s. how much work must be done on the hoop to stop it?

Answers

The work needed is equal to the KE of the hoop which is = 150 * 0.130^2 / 2 ...(1) 
Let the following be:r be the radiuscenter of mass in the moment of inertia is denoted by:
I = 150 r^2 kg m^2. 
The angular velocity relative to the center of mass is: 
w = 0.130 / r rad / s. 
Rotational KE = Iw^2 / 2 
= (150 * r^2) (0.130 / r)^2 / 2 
= 150 * 0.130^2 / 2 J ...(2) 
Adding (1) and (2): 
Total KE = 130 * 0.130^2 
= 2.2 J.

An electron is released from rest and travels over a potential difference of 2500 v. what is its final velocity?

Answers

The electron travels through a potential difference of [tex]\Delta V =2500 V[/tex]. This means that the loss of electrostatic potential energy of the electron is
[tex]\Delta U = q \Delta V= (-1.6 \cdot 10^{-19}C)(2500 V)=-4 \cdot 10^{-16}J[/tex]
where q is the electron charge.

For the law of conservation of energy, the electron (starting from rest and accelerated by the potential difference) acquired a kinetic energy equal to the negative of this loss of potential energy:
[tex]\Delta K=-\Delta U[/tex]
where [tex]\Delta K =K_f - K_i = K_f[/tex] because the electron is initially at rest and so its kinetic energy is zero. Since 
[tex]K_f= \frac{1}{2}mv^2 [/tex]
where m is the electron mass, we can find the final velocity v of the electron:
[tex]v= \sqrt{ \frac{2K_f}{m} }= \sqrt{ \frac{2\cdot 4 \cdot 10^{-16} J}{9.1 \cdot 10^{-31} kg} }=3.0 \cdot 10^7 m/s [/tex]

Why does the plot show vertical jumps at the melting and boiling points?

Answers

I think this happens because during melting or boiling at constant temperature, the entropy dramatically increases because energy is removed from the system during the change. Entropy increases with increase in temperature, entropy increases steadily with increasing temperature up to the melting point of the solid, where the entropy increases further due to addition of freedom of molecules which increases the randomness of the substance. At boiling point of liquid, another abrupt increase in entropy occurs, this results from increased volume available to the atoms or molecules as they enter the gaseous state. 

A flea jumps straight up to a maximum height of 0.540 m . what is its initial velocity v0 as it leaves the ground?

Answers

For an uniformly accelerated motion, we can write
[tex]2ah=v_f^2-v_0^2[/tex]
where [tex]a=g=-9.81 m/s^2[/tex] is the acceleration of this motion, which in this problem is the gravitational acceleration, with a negative sign because it points downward, against the direction of the motion; h=0.540 m is the distance covered by the flea, and [tex]v_0[/tex] is the initial velocity. 

At the maximum height, the velocity is zero, so [tex]v_f =0[/tex]. Therefore we  can solve to find [tex]v_0[/tex]:
[tex]v_0 = \sqrt{2ah}= \sqrt{2(9.81 m/s^2)(0.540 m)} =3.25 m/s[/tex]

A plane takes off in san francisco at noon and flies toward the southeast. an hour later, it is 400 kilometers east and 300 kilometers south of its starting location. assuming the plane flew in a straight line, how far did it travel? how many degrees south of east did the plane fly?

Answers

This first step involves a right triangle. If the plane is 400 km east and 300 km south of the origin, and it flew in a straight line, then you can construct a right triangle with side lengths 300, 400, and c. You may recognize that these are multiples of the Pythagorean triple 3, 4, 5, so the side length c is 500 km. Otherwise, you would write 
[tex]c^2 = 300^2+400^2 \\ c = 500[/tex]. 

This second step is, if I am correctly interpreting "degrees south of east," to find the angle formed by the horizontal line representing the east and the path of the plane. I made a diagram that does just that (see attached). You can use a trig function of one of the angles to solve. I chose
[tex]tan(C)= \frac{3}{4} \\ arctan( \frac{3}{4})=36.870[/tex]. Thus, I believe it is 37° south of east.

A 0.025m radius toy top is spinning at a rate of 150rpm, what is the angular velocity? What is the linear velocity of the paint on the outside edge?

Answers

a) The angular velocity of the disk is 150 rpm (revolutions per minute). We can convert it into proper units, i.e. radiants per seconds, keeping in mind that:
[tex]1 rev = 2 \pi rad[/tex]
[tex]1 min = 60 s[/tex]
so the angular speed is
[tex]\omega = 150 \frac{rev}{min} = 150 \frac{2 \pi rad}{60 s} =15.7 rad /s[/tex]

b) The linear velocity is given by
[tex]v=\omega r[/tex]
since the radius is r=0.025 m, the linear velocity at the edge of the disk is
[tex]v= \omega r = (15.7 rad/s)(0.025 m)=0.39 m/s[/tex]

If you shook the end of a rope up and down 5 times each second, what would be the period of the waves set up in the rope?

Answers

Shooking the rope up and down 5 times per seconds means that there are 5 cycles of the wave (or 5 crests) in one second, and so its frequency is [tex]f=5 Hz[/tex]. 

The period T is the reciprocal of the wave's frequency, therefore it is
[tex]T= \frac{1}{5 Hz}=0.20 s [/tex]

Final answer:

Shaking the rope at 5 times per second sets up waves with a frequency of 5 Hz. The period of these waves, which is the inverse of frequency, would be 0.2 seconds.

Explanation:

When you shake the end of a rope up and down 5 times each second, you are creating waves with a certain frequency. The frequency is the number of complete waves that pass a given point in one second, and it is measured in hertz (Hz). Since you're shaking the rope 5 times per second, the frequency of the waves set up in the rope is 5 Hz.

The period of a wave is the time it takes for one complete wave cycle to pass a point. It is the inverse of the frequency. To calculate the period (T), you would use the formula:

T = 1 / f, where 'f' is the frequency.

So in this case:

T = 1 / 5 Hz = 0.2 seconds.

Therefore, the period of the waves set up in the rope is 0.2 seconds.

Both lead and zinc are formed as precipitates. Which of these is a step in the formation of the minerals?

elements combine at high pressure
magma cools after a volcanic eruption
atoms combine in water to form solids
materials break up due to rise in temperature

Answers

Minerals are naturally occurring inorganic (they're not formed from amino acids, peptides, or enzymes) chemical compounds.

From the given options, the following describes a step in the formation of the minerals: materials break up due to rise in temperature.

Correct answer: D

Final answer:

Lead and zinc minerals commonly form as precipitates from hot underground water cooling and depositing solid minerals. They can also form from the cooling and crystallization of magma, particularly in the presence of hydrothermal fluids.

Explanation:

Lead and zinc minerals can form through several geological processes, and one of the key methods for their formation is through the precipitation of minerals from an aqueous (water) solution. When hot underground water that has been heated by magma cools as it moves through the Earth's crust, it can deposit solid minerals. This happens because the solubility of substances often decreases as the temperature drops, leading to the formation of solids from the previously dissolved elements or compounds.

Additionally, minerals can form when magma cools after a volcanic eruption or during more gradual processes. If magma cools slowly, the minerals have time to form large, identifiable crystals. Conversely, rapid cooling leads to the formation of small crystals or even glassy textures without discernible crystals.

Hydrothermal mineral deposits are another significant source of minerals, such as lead and zinc. These deposits form when super heated water from magma chambers dissolves minerals, and as the solution cools and travels towards the surface, the dissolved minerals precipitate out, often forming rich ore bodies.
