Force = Mass X Acceleration

F = 5 x 2

F = 10 N

Two teams of nine members each engage in tug-of-war. Each of the first team's members has an average mass of 68 kg and exerts an
diamong [38]

Answer:

(a) Acceleration  = 0.1063 m/s^2      (Second team wins)

(b) Tension in rope = 65.106 N

Explanation:

Total mass of first team = 68 * 9 = 612 kg

Total force of first team = 1350 * 9 = 12150 N

Total mass of second team = 73 * 9 = 657 kg

Total force of seconds team = 1365 * 9 = 12285 N

Difference in force = 12285 - 12150 = 135 N   (towards the second team as it has more force)

(a) For acceleration we get:

F = m * a

135 = (mass of both teams) * a

a = 135 / (612 + 657)

acceleration  = 0.1063 m/s^2      (Second team wins)

(b) Since we know the acceleration of the first team (pulling being pulled towards the second team at an acceleration of 0.1063 m/s^2) , we can find out the force required to move them:

Force required for first team = mass of first team * acceleration

Force required = 612 * 0.1063

Force required = 65.106 N

This is the force exerted on the first team through the rope, so the tension in the rope will also be 65.106 N.

Question 4 What would be the UCS for Tab the dog? O The shock O The flowers and fence O Fear O The boundary Question 5​
Harrizon [31]

The unconditioned stimulus (UCS) for Tab the dog is: B. The flowers and fence.

<h3>The types of stimuli.</h3>

In Science, the two (2) stimuli that are repeatedly paired in classical conditioning include:

  • Conditioned stimulus
  • Unconditioned stimulus

<h3>What is an unconditioned stimulus?</h3>

An unconditioned stimulus can be defined as a stimulus that is capable of naturally triggering a response, before or without any conditioning while it elicit a specific response without learning.

  • This ultimately implies that, an unconditioned stimulus leads to an automatic response in a living organism such as a dog.

In this scenario, the unconditioned stimulus (UCS) for Tab the dog is simply the flowers and fence.

What happens to the ray of light when it travels from glass to water?
vodomira [7]

Glass and water are thicker and heavier than air. They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction.
