What happens when two forces act in the same direction

Answers

Answer 1

2x the force will act on the object and the object should accelerate considering a frictionless surface

Answer 2

Final answer:

When two forces act in the same direction, they add together, resulting in a greater overall force that can, for example, make it easier to move a heavy object.

Explanation:

When two forces act in the same direction, their effects add up, resulting in a larger overall force. This can be illustrated by imagining you and a friend trying to move a heavy box. If you both apply a force in the same direction, the resultant force on the box is the sum of your individual forces, making it easier to move the box. If, on the other hand, the forces were applied in opposite directions, the resultant force would be the difference between these two forces, according to which direction is assigned as positive. This reflects a basic principle in physics that forces are vectors and thus adhere to vector addition. It is important to note that this concept is different from Newton's third law, which states that for every action, there is an equal and opposite reaction, but this law refers to forces between two different bodies, rather than the cumulative effect of forces acting on the same body in the same direction.

Based on the diagram of a roller coaster car on a roller coaster track, what statement is true?
A) The car at point A has more kinetic energy than the car at point C.
B) The car at point C has less kinetic energy than the car at point B.
C) The car at point C has more kinetic energy than the car at point B.
D) The car at point D has less potential energy than the car at point B.

Answers

Answer:

B) The car at point C has less kinetic energy than the car at point B.

Explanation:

We have two types of energy involved in this situation:

- Gravitational potential energy: this is the energy related to the heigth of the car, and it is given by [tex]U=mgh[/tex], where m is the mass of the car, g is the gravitational acceleration, and h is the heigth of the car. The potential energy is higher when the car is located higher above the ground.

- Kinetic energy: this is the energy due to the motion of the car, and it is given by [tex]K=\frac{1}{2}mv^2[/tex], where m is the mass of the car and v is its speed. The kinetic energy is higher when the speed of the car is higher.

- The law of conservation of energy states that the total mechanical energy of the car (sum of potential energy and kinetic energy: [tex]E=U+K[/tex]) is constant). This implies that when the car is at a higher point, the kinetic energy is less (because U is larger, so K must be smaller), while when the car is at a lower point, the kinetic energy is larger.

- Based on what we have written so far, we can conclude that the correct statement is:

B) The car at point C has less kinetic energy than the car at point B.

Because the car at point C is located at a higher point than point B, so the car at point C has larger potential energy than at point B, which implies that car at point C has less kinetic energy than the car at point B.

Answer: The answer is C

A car at point B has more kinetic energy than the car at point D.

Kinetic energy is energy at work.

Potential energy is stored energy.

A) Energy is transferred from Joey to the water. The temperature of the water increases.
B) Energy is transferred from the water to Joey. The temperature of the water increases.
C) Energy is transferred from the water to Joey. The temperature of the water decreases.
D) Energy is transferred from the Joey to the water. The temperature of the water decreases.

Answers

Hello!

Energy always flows from hot to cold so the best answer would be A. Even though it will be a small change due to the difference in masses and the difference in body temp and the pool water on a cool morning.

Hope this helps. Just remember heat/energy always flows from hot to cold. Never the reverse. So whatever is more hot has heat energy to give up to the other.

A rope pulls on a metal box at an angle of 60.0° with a force of 255 N. The box moves horizontally for 15.0 m. How much work was done on the box?

Answers

The work done by the rope on the box is equal to:
[tex]W=Fd \cos \theta[/tex]
where F is the force applied by the rope, d the distance covered by the box and [tex]\theta [/tex] is the angle between the direction of the force and of the displacement.

Using the data of the problem: [tex]F=255 N[/tex], [tex]d=15.0 m[/tex] and [tex]\theta = 60^{\circ}[/tex], we find the work:
[tex]W=(255 N)(15.0 m)(\cos 60^{\circ})=1912.5 J[/tex]

Final answer:

The work done on the box is found by first calculating the horizontal component of the applied force and then multiplying it by the distance moved. The total work done is 1912.5 Joules.

Explanation:

The question involves calculating the work done on a metal box which is being pulled horizontally by a rope exerting a force at an angle. This is a classic physics problem that involves understanding the components of force and the definition of work in a physical context.

To calculate the work done on the box, we need to find the component of the force that acts in the direction of the box's movement (horizontal direction). The force is given as 255 N at an angle of 60°. The horizontal component (Fhorizontal) of this force is F * cos(θ), which gives 255 N * cos(60°) = 127.5 N. The work done (W) is the product of this horizontal force component and the distance (d) over which it acts. Hence, W = Fhorizontal * d = 127.5 N * 15.0 m = 1912.5 Joules.

The density of aluminum is 2.7 g/cm3. What is the volume of a piece of aluminum if its mass is 8.1 grams?

Answers

density = 2.7g/cm3
mass =8.1grams
from density =(mass)/volume
we can determine the volume of aluminium by simply changing the subject of the subject of the formula from density to volume
so we have

volume=mass/density
=(8.1grams)/(2.7g/cm3)
=3cm3

Final answer:

To find the volume of a piece of aluminum with a mass of 8.1 grams and a density of 2.7 g/cm³, calculate the volume by dividing mass by density, giving you a volume of 3 cm³.

Explanation:

The density of aluminum is given as 2.7 g/cm³. If the mass of a piece of aluminum is 8.1 grams, you can calculate its volume using the formula density (p) = mass (m) / volume (V). In this case, you would rearrange the formula to solve for volume, resulting in V = m / p. Plugging in the known values, we get V = 8.1 g / 2.7 g/cm³.

After performing the division, we find the volume of the piece of aluminum is 3 cm³. Thus, the piece of aluminum has a volume of 3 cubic centimeters for its mass of 8.1 grams when the density is 2.7 g/cm³.

We spend our lives in visible light without risks to our health. Yet exposure to UV waves in sunlight can cause skin cancer. What is the BEST explanation for this? A) UV waves are longer and carry more energy. B) UV waves are higher frequency and carry more energy. C) UV waves have a lower frequency and carry more energy. Eliminate D) UV waves travel faster than visible light and have more energy.

Answers

It's B. The higher the frequency the more the energy.

Answer:

B) UV waves are higher frequency and carry more energy.

Explanation:

The light that we see around us is called visible light which is just 7% of the complete electromagnetic wave spectrum. This EM spectrum has other waves as well such as gamma, UV, IR, Radio etc. These waves are classified according to their wavelengths and frequency.

Gamma rays have the highest frequency and thus are most energetic while radio waves smallest frequency and least energy.

The UV waves coming from the Sun have higher frequency than visible light and thus are more energetic. This is the reason that UV waves can cause skin cancer. The ozone layer in the atmosphere absorbs the UV waves. The increased level of pollution is affecting this layer and thus increasing the exposure to UV waves and hence risk of skin cancer.

a 90 kg architect is standing 2 meters from the center of a scaffold help up by a rope on both sides. the scaffold is 6m long and has a mass of 200kg. what is the tension on each rope

Answers

We can solve the problem by requiring the equilibrium of the forces and the equilibrium of torques.

1) Equilibrium of forces:
[tex]T_1 - W_p - W_s + T_2 =0[/tex]
where
[tex]W_p = (90kg)(9.81 m/s^2)=883 N[/tex] is the weight of the person
[tex]W_s = (200kg)(9.81 m/s^2)=1962 N[/tex] is the weight of the scaffold
Re-arranging, we can write the equation as
[tex]T_1 = 2845 N-T_2[/tex] (1)

2) Equilibrium of torques:
[tex] T_1 \cdot 3 m - W_p \cdot 2 m - T_2 \cdot 3m =0[/tex]
where 3 m and 2 m are the distances of the forces from the center of mass of the scaffold.
Using [tex]W_p = 883 N[/tex] and replacing T1 with (1), we find
[tex]2845 N \cdot 3 m - T_2 \cdot 3 m - 833 N \cdot 2 m - T_2 \cdot 3 m=0[/tex]
from which we find
[tex]T_2 = 1128 N[/tex]

And then, substituting T2 into (1), we find
[tex]T_1 = 1717 N[/tex]

Since the beginning of time, some people have believed that the Earth is flat. Beginning around 300 B.C., however, some began to wonder if the Earth is actually spherical in shape. Those that favored the flat Earth theory made the following observations: The Earth is stable because it is a flat landmass sandwiched between a flat layer of air and a flat layer of water. If the Earth is spherical, then oceans should be curved on top, but they aren't. Some rivers flow for hundreds of miles but only fall a few feet. The rivers should fall farther if the Earth is spherical. If the Earth is spherical, people and animals that inhabit the Earth would notice as they walked along its surface. Since mariners are able to use flat compasses to navigate their ships without crashing, the Earth must not be a sphere. Those that disputed the flat Earth theory countered the claim by observing that Christopher Columbus was able to sail around the Earth without falling off the edge and later, by presenting satellite imagery taken from space of a spherical Earth.
