Answer:

C) People need time to shift between two different stimuli.

Explanation:

Wilhelm Wundt attempted to study the behavior of mind by measuring and observing the body. He conducted an experiment which would measure the rate of speed of thoughts of the subjects to make any judgment. He experimented by measuring the tie with a pendulum swing. He is referred to as the 'father of experimental psychology' because of his efforts in the field of psychology.

A 100 N force is applied to a 500 kg crate resting on frictionless wheels.

Alla [95]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

f is the force

m is the mass

From the question we have

$a = \frac{100}{500} = \frac{1}{5} = 0.2 \\$

We have the final answer as

Hope this helps you

Three observers watch a train pull away from a station toward the right of the platform. Observer A is in one of the train’s car

juin [17]

Observer A is moving inside the train

so here observer A will not be able to see the change in position of train as he is standing in the same reference frame

So here as per observer A the train will remain at rest and its not moving at all

Observer B is standing on the platform so here it is a stationary reference frame which is outside the moving body

So here observer B will see the actual motion of train which is moving in forward direction away from the platform

Observer C is inside other train which is moving in opposite direction on parallel track. So as per observer C the train is coming nearer to him at faster speed then the actual speed because they are moving in opposite direction

So the distance between them will decrease at faster rate

Now as per Newton's II law

F = ma

Now if train apply the brakes the net force on it will be opposite to its motion

So we can say

- F = ma

$a = \frac{-F}{m}$

so here acceleration negative will show that train will get slower and its distance with respect to us is now increasing with less rate

It is not affected by the gravity because the gravity will cause the weight of train and this weight is always counterbalanced by normal force on the train

So there is no effect on train motion

If an atom has an atomic number of 2, it will be stable with 2 electrons in its valence shell. Group of answer choices True Fals

torisob [31]

Answer: True

Explanation:

Atomic number is defined as the number of protons or the number of electrons that are present in an electrically neutral atom.

Atomic number = Number of protons = number of electrons = 2

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electronic configuration will be $1s^2$
