Jack always drank soda whenever he hung out with his friends. On one particular occasion, Jack didn't have any soda to drink and as soon as he saw his friends, he became thirsty. Jacks friends represent the: Group of answer choices Unconditioned Response Conditioned Stimulus Unconditioned Stimulus Conditioned Response

Answers

Answer 1
Answer:

Answer:

Conditioned stimuli

Explanation:

Due to jack always taking soda whenever he hangs out with his friends, his nervous system has been conditioned to associate the presence of his friends to taking soda. This means that his body system will start to interprete the presence of his friend as a stimulus to prompt him to drink, and the natural way his body can make him want to drink is by initiating the thirst reactions. On this particular day, Jack seeing his friend was perceived by his body as time for a drink so he became thirsty.

What is the momentum of a dog of mass 20 kg that is running east with a speed of 3 m/s?

Answers

Answer:

60 kg.m/s

Explanation:

Momentum is the product of mass and velocity

p=m*v where m is mass in kg and v is velocity in m/s

Given that;

m=20kg and v=3m/s then;

p= 20×3= 60kgm/s

Answer:

60 kg * m/s east.

Explanation:

Momentum is a vector quantity, so you must include direction in the answer. Work by the guy above me ^_^

A 55.0-kg skydiver free falls for a period of time before opening his parachute. What is his kinetic energy when he reaches a velocity of 16.0 meters/second? 7,040 J
440 J
539 J
cannot be determined without knowing his height above the ground

Answers

Given:

Mass of the skydiver:55 Kg

Velocity of the skydiver (v): 16m/s

Kinetic energy= 1/2mv^2

Kinetic energy= 1/2(55x16x16)

Kinetic energy= 7040J

A car traveling due east at 20 m/s reverses its direction over a period of 10 seconds so that it is now traveling due west at 20 m/s. What is the direction of the car’s average acceleration over this period?

Answers

Answer:

west

Explanation:

We can take east as positive (+) direction and west as negative (-) direction. With this sign convention, we have:

- Initial velocity: u = +20 m/s (due east)

- Final velocity: v = -20 m/s (due west)

- Time taken to change velocity: t = 10 s

Therefore, we can use the formula for the acceleration to calculate the car's acceleration:

And the negative sign means the direction of the car's acceleration is west.

An object is acted upon by a constant force which gives it a constant acceleration a. At a certain time t1, having started from rest at t = 0, it has kinetic energy K1. At what time t2 has its kinetic energy doubled?

Answers

Answer:

Explanation:

The kinetic energy of a body is that energy it possesses due to its motion. In classical mechanics, this energy depends only on its mass and speed, as follows:

The speed in an uniformly accelerated motion is given by:

Replacing this expression in the formula for the kinetic energy, we have:

So, if we have :

What is the acceleration of a body revolving in a circle at uniform speed? A. The acceleration is zero.
B. The acceleration is directed tangentially.
C. The acceleration is directed toward the center.
D. The acceleration is directed away from the center.

Answers

The acceleration is directed towards the centre when a body revolving in a circle at uniform speed.

Answer: Option C

Explanation:

When an object w=is moving with an uniform speed, its acceleration will be constant because acceleration depends upon the velocity of the object.  Also due to circular motion, the acceleration is directed towards the center point. The tangential component of the acceleration tend to be constant in this zero.

The acceleration of a body revolving in a circle at uniform speed is directed toward the center. (C)  It's called "centripetal acceleration".

Recall some things you already know about projectile motion. Does a force in the vertical direction affect the horizontal component of an object’s velocity? In this situation, can you use the horizontal velocity component to find the time required to travel some horizontal distance?

Answers

Answer:

vertical force cannot change the velocity on the x-axis.   t =x/v₀ₓ

Explanation:

The force is a vector magnitude, so the forces on the x-axis affect the acceleration on this axis. Consequently a vertical force cannot change the velocity on the x-axis.

      = m g

    Fₓ = 0

The horizontal velocity in projectile motion is constant, if we neglect the air resistance, so it can be used to find the time of a horizontal displacement

       x = v₀ₓ t

       t =x/v₀ₓ

The only magnitude that is the same for both movements is the time that is a scalar
