Salmon often jump waterfalls to reach their breeding grounds. Starting 3.15 m from a waterfall 0.45 m in height, at what minimum speed must a salmon jumping at an angle of 33.2 degree leave the water to continue upstream? The acceleration due to gravity is 9.81 m/s2. Answer in units of m/s.

Answers

Answer 1

Let the salmon jump with speed v at an angle of 33.3 degree

So here we can find out the components of his velocity in x and y direction

[tex]v_x = v cos33.2[/tex]

[tex]v_y = v sin33.2[/tex]

now the horizontal displacement of the salmon is 3.15 m so he cover this horizontal distance with constant speed as there is no acceleration in x direction

here we can say

[tex]v_x * t = 3.15[/tex]

[tex]v cos33.2 * t = 3.15[/tex]

[tex]v*t = 3.76[/tex]

now in Y direction it is an accelerated motion as it is accelerated due to gravity

[tex]y = v_y * t + \frac{1}{2}at^2[/tex]

[tex]-0.45 = v sin33.2* t - \frac{1}{2}*9.8* t^2[/tex]

now we will plug in v*t = 3.76

[tex]-0.45 = 3.76 * sin33.2 - 4.9 * t^2[/tex]

[tex]4.9 t^2 = 2.51[/tex]

[tex]t^2 = 0.512[/tex]

[tex]t = 0.72 s[/tex]

now speed v is given by equation above

[tex]v*t = 3.76[/tex]

[tex]v*0.72 = 3.76[/tex]

[tex]v = 5.25 m/s[/tex]

so here he must have to jump with minimum speed of 5.25 m/s

When non-nerve cells become involved in response to signals, which type of receptor goes into action? A. enzyme-linked receptor B.ion-channel linked receptor C. intracellular receptor D. endomembrane receptor. CAN SOMEONE PLZ HELP ME!

Answers

The answer is; A.

This occurs for a cell that has no ion channel receptors. These cells have surface receptors that change conformation on the binding by an extracellular ligand on the active site. This change in conformation results in an initiation of a chain cascade of biochemical reactions inside the cell.  An example is cells responding to insulin and glucagon hormone that bind on their surface receptors that invokes cell responses that regulate blood sugar levels in the blood.


The voltage across the secondary winding is 10,000 V, and the voltage across the primary winding is 25,000 V. If the primary winding has 200 coils, how many coils are in the secondary winding?

Answers

Answer

80 coils


Explanation

The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:

Np/Ns  =  Vp/Vs

200/Ns  = 25,000/10,000

200 × 10,000  = 25,000Ns

2,000,000 = 25000Ns

Dividing both sides by 25,000,

Ns = 2,000,000/25,000

The tendency of an object with a weight to resist a change in its motion.

Answers

2. a cruise ship docked in a port

In fact, inertia is the resistance of an object to any change in its velocity/change of its state of motion. The inertia of an object depends only on the mass of the object: the greater the mass, the larger the inertia. In this case, the object with largest mass among the choices is the cruise ship docked in the port, so this is the object with most inertia.

3. gram

Mass represents the quantity of matter inside an object, and it is measured in grams (g). Actually, the SI units of the mass is the kilogram (kg), a multiple of the gram: 1 kg = 1000 g.

4. [tex]m/s^2[/tex]

Acceleration is defined as the rate of change of velocity per unit time:

[tex]a=\frac{\Delta v}{\Delta t}[/tex]

The change in velocity, [tex]\Delta v[/tex], is measured in m/s, while the time [tex]\Delta t[/tex] is measured in seconds (s): therefore, the acceleration is measured in

[tex][a]=\frac{[m/s]}{[s]}=[\frac{m}{s^2}][/tex]

5. Newtons

The Newton (N) is the SI unit used for the force. The force is defined as the product between mass (m) and acceleration (a):

[tex]F=ma[/tex]

since the mass is measured in kg and the acceleration in m/s^2, 1 Newton corresponds to

[tex]1 N= 1 kg \frac{m}{s^2}[/tex]

6. 1030 N

Given m=1.04 kg (mass of the hockey puck) and [tex]a=987 m/s^2[/tex] (acceleration of the hockey puck), the force needed to accelerate the puck with this acceleration is given by Newton's second law:

[tex]F=ma=(1.04 kg)(987 m/s^2)=1026 N[/tex]

which corresponds (approximately) to option C) 1030 N.

7. 520 kg

Given [tex]a=9.71 m/s^2[/tex] (acceleration of the car) and F=5050 N (net force applied on the car), we can find the mass of the car by using again Newton's second law:

[tex]m=\frac{F}{a}=\frac{5050 N}{9.71 m/s^2}=520 kg[/tex]

8. 1.00 m/s2

In this case, the net force applied by Amber is F=35 N.

The total mass of the brother+wagon is

[tex]m=32 kg+3 kg=35 kg[/tex]

Therefore, we can find the acceleration of the system by using again Newton's second law:

[tex]a=\frac{F}{m}=\frac{35 N}{35 kg}=1.00 m/s^2[/tex]

9. forward

This is because of the inertia: in fact, the car (and the groceries inside it) is initially moving forward. When it stops, the groceries inside the car tends to continue moving forward: due to their inertia, they tends to continue their motion with constant speed, until they are stopped by an external force.

10. The tendency of an object with mass to resist a change in its motion.

Inertia is exactly this: the tendency of an object with mass to resist a change in its motion. This means that an object at rest tends to stay at rest, while an object in motion tends to keep its speed. The inertia of an object depends only on its mass: the larger the mass, the greater the inertia.

The cunninghams are moving across the country. Mr.cunningham leaves 2.5 hours before mrs.cunningham. If he averages 40 mph and she averages 65 mph,how long will it take Mrs.cunningham to overtake mr.cunningham?

Answers

When she starts out, he is (40x2.5)= 100 miles ahead of her.

She gains (65-40)= 25 miles on him every hour.

It takes her (100/25)= 4 hours to catch up to him.

It will take Mrs. Cunningham 4 hours to overtake Mr. Cunningham.

To determine how long it will take Mrs. Cunningham to overtake Mr. Cunningham, use the following steps:

1. Calculate the distance Mr. Cunningham travels before Mrs. Cunningham starts:

  Distance = Speed × Time [tex]\[ \text{Distance} = 40 \text{ mph} \times 2.5 \text{ hours} = 100 \text{ miles} \][/tex]

2. Determine the relative speed at which Mrs. Cunningham is gaining on Mr. Cunningham:

  Relative speed = Mrs. Cunningham's speed - Mr. Cunningham's speed  [tex]\[ \text{Relative speed} = 65 \text{ mph} - 40 \text{ mph} = 25 \text{ mph} \][/tex]

3. Calculate the time it takes for Mrs. Cunningham to cover the distance between them at the relative speed:

  Time = Distance / Relative speed[tex]\[ \text{Time} = \frac{100 \text{ miles}}{25 \text{ mph}} = 4 \text{ hours} \][/tex]

if a 5-kg bowling ball is projected upward witha velocity of 2.0 m/s, then what is the recoil velocity of the Earth(mass=6.0×10^24kg)

Answers

by the concept of momentum conservation we can say

if net force on a system of mass is ZERO then its momentum will remain conserved

Here a ball is projected upwards so if we take Ball + Earth as a system then total momentum of the system will remain conserved

Initially when ball is on the surface of earth the system has zero momentum and hence we can say after throwing the ball momentum of earth + ball must be zero

now using same equation we can say

[tex]P_{ball} + P_{earth} = 0[/tex]

[tex]m_1v_1 + m_2v_2= 0[/tex]

given that

[tex]m_1 = 5 kg[/tex]

[tex]v_1 = 2 m/s[/tex]

[tex]m_2 = 6 * 10^{24} kg[/tex]

from above equation velocity of earth will be

[tex]v_2 = \frac{m_1 v_1}{m_2}[/tex]

[tex]v_2 = \frac{5*2}{6 * 10^{24}}[/tex]

[tex]v_2 = 1.67 * 10^{-24} m/s[/tex]

so above will be the recoil speed of earth

a rock is dropped from a bridge. what happens to the magnitude of the acceleration and the speed of the rock as it falls?

a) both acceleration and speed increase

b) both acceleration and speed remain the same

c) acceleration increases & speed decreases

d) acceleration remains the same & speed increases

Answers

If a rock is dropped from a bridge, its acceleration remains the same (9.8 m/s², the acceleration of gravity on Earth, no matter how heavy the rock is), and its speed increases at the rate of (9.8 meters per second for every second it falls).

The acceleration of the rock remains the same while the speed increases as the rock moves downwards.

The motion of an object dropped from a certain height is affected by Earth's gravitational influence.

The acceleration due gravity on the object will be constant throughout the motion. The direction of this acceleration due to gravity is downwards.

The object's speed increases as the object moves downwards and it will eventually become maximum before the object hits the ground.

The direction of the object's speed is always in the direction of the object's motion.

Thus, we can conclude that the acceleration of the rock remains the same while the speed increases as the rock moves downwards.

Use the equation

[tex]{v_f}^2-{v_i}^2=2a\Delta x[/tex]

The final velocity [tex]v_f[/tex] is 68 m/s, the acceleration [tex]a[/tex] is 8 m/s^2, and the net displacement [tex]\Delta x[/tex] is 33 m, so you can solve for the initial velocity [tex]v_i[/tex]:

Final answer:

To calculate the initial velocity, use the equation Vf^2 = Vo^2 + 2aΔx, where Vf is the final velocity, Vo is the initial velocity, a is the acceleration, and Δx is the displacement. Plug in the given values to find Vo.

Explanation:

To calculate the initial velocity of an object displaced 33 meters while accelerating at 8 m/s^2 and reaching a final velocity of 68 m/s, we can use the equation:

Vf^2 = Vo^2 + 2aΔx

Where Vf is the final velocity, Vo is the initial velocity, a is the acceleration, and Δx is the displacement.

Plugging in the given values:

68^2 = Vo^2 + 2(8)(33)

Vo^2 = 4624 - 528

Vo^2 = 4096

Vo = √4096

Vo = 64 m/s

Answers

Here in the given situation two forces are acting on the dummy from two perpendicular directions

Since force is a vector quantity so we need to add two or more forces by vector addition method

Now here we know that two forces are perpendicular to each other

So we will use Pythagoras theorem

given that

[tex]F_1 = 130.0 N[/tex]

[tex]F_2 = 4500.0 N[/tex]

now plug in all in the above equation

[tex]F_{net} = \sqrt{130^2 + 4500^2}[/tex]

All components of the force acting on the car are:

• The Normal force perpendicular to the surface of the car.

• The force of gravity in downhill direction.

• The breaking force in the uphill direction.

• The friction force in the uphill direction.

Further Explanation:

Free body diagram is the graphical representation or illustration of all the forces applied on the body with their directions. This helps us to visualize all the applied forces on the body with their directions and make us possible to solve complex problems based on kinematics.

The inclination of the road is [tex]20^\circ[/tex].

Concept:

The free body diagram is drawn as shown in Figure 1.

The car is moving on incline hill making an angle [tex]20^\circ[/tex] with the plane surface. When sudden break is applied to the car it skids to some distance. As soon as the brakes are applied, the car experiences a friction force due to brakes and starts slowing down.

The friction force offered by the hill is dependent on the normal force which is equal to the component of the weight acting perpendicular to the road.

The coefficient of static friction [tex]\mu[/tex] is depend upon the nature of surface of the irregularities. The friction force acts in the direction opposite to the motion.

The car has its normal force and it is the component of the contact force which is always perpendicular to the surface of the object.

The car has component of the force in the downward direction along the hill due to gravity called as weight. It’s magnitude depend upon the mass of the body and expressed as [tex]mg[/tex]. the term [tex]g[/tex] is called acceleration due to gravity and it has a constant value of [tex]9.81\text{ m/s}^2[/tex].

The statement which is true about using both a screw driver and an electric screw driver to put a screw in a wall stud is: B. the same work was done, but the electric screw driver increased the rate of work.

Work can be defined as a measure of energy transfer that takes place when an object is moved due to the application of a force along a displacement.

Hence, the work done by an object is the multiplication (product) of the perpendicular force acting on the object and the distance it covers.

Mathematically, work done is given by the formula:

[tex]Work\;done = Force \times displacement[/tex]

Generally, a screw driver and an electric screw driver can be used to perform the same work of put a screw in a wall stud.

However, an electric screw driver has a motor, which makes the speed (work rate) of putting a screw in the wall faster than a screw driver.

Additionally, a screw driver is a mechanical tool and as such it requires more human effort to put a screw in a wall stud, thereby, decreasing the rate of work.

In conclusion, the same work was done by using both a screw driver and an electric screw driver, but the electric screw driver increased the rate of work.

The cheetah can maintain its maximum speed for only 7.5 s. What is the minimum distance the gazelle must be ahead of the cheetah to have a chance of escape? (After 7.5 s the speed of cheetah is less than that of the gazelle.) Answer in units of m.

Answers

Final answer:

The minimum distance the gazelle must be ahead of the cheetah to have a chance of escape is 112.5 m.

Explanation:

To find the minimum distance the gazelle must be ahead of the cheetah, we need to calculate the distance the cheetah covers in 7.5 seconds when it reaches its maximum speed.

Using the formula:

Displacement = Initial velocity * Time + (1/2) * Acceleration * Time^2

Since the cheetah starts from rest, its initial velocity is 0 m/s. The acceleration is not given in the question, so we can't calculate the exact distance. However, we can use the example provided, where the cheetah accelerates at 4 m/s², to illustrate the calculation.

Let's assume the cheetah's acceleration is 4 m/s². Plugging in the values:

Displacement = (0 m/s) * (7.5 s) + (1/2) * (4 m/s²) * (7.5 s)^2

Displacement = 0 + (1/2) * 4 m/s² * 56.25 s²

Displacement = 0 + 2 * 56.25 m = 112.5 m

Therefore, the minimum distance the gazelle must be ahead of the cheetah is 112.5 meters.

A force of 45 N is exerted on an object, resulting in an acceleration of 5 m/s^2 for the object. What will the objects acceleration be if the force doubles.

Why would an object float in water, but sink in rubbing alcohol?

Answers

Because water is more dense than the object but rubbing alcohol is less dense than the object

Final answer:

An object floats or sinks based on the densities of the object and the fluid. Water's higher density and surface tension compared to rubbing alcohol enables certain objects to float in it but sink in rubbing alcohol.

Explanation:

The object's ability to float or sink in a fluid depends on the densities of the object and the fluid. If the object's average density is less than that of the fluid it will float. This is because the fluid, having a higher density, contains more mass and hence more weight in the same volume. The buoyant force which equals the weight of the fluid displaced is thus greater than the weight of the object. On the other hand, an object denser than the fluid will sink.

Water has a higher density than rubbing alcohol thus objects that can float in water may sink in rubbing alcohol if their density is greater than that of the alcohol. Additionally liquids such as water exhibit properties such as cohesion and surface tension which can support objects denser or heavier than the water to some extent until the surface tension is broken. However the surface tension of rubbing alcohol is significantly lower than that of water affecting the floating capability of the object.

How do I find the direction of the velocity and acceleration ?

Answers

Answer

The mainly three types of directions exits between velocity and acceleration.

Explanation

The velocity and acceleration are the vector quantities as having both magnitude and direction. To direction of both factors depends upon the speed. for example, we take a car to observe the direction of these two factors, then there will be no direction when the car is at rest.

When the car moves at uniform velocity then its direction will be forward but there will be no direction of acceleration.

When the car moves with increasing speed continuously, then the direction of velocity and acceleration will be parallel.

When the car is at speed and trying to slow down its speeds, it will create acceleration. In this case, the direction of velocity and acceleration will be in the opposite.
