When a ball is fired from a cannon horizontally, then it will follow the projectile path. So the cannonball most closely follow the path number 2.

You can also see in the attachment my drawing.

<h3>Which of the paths below would the puck most closely follow after receiving the kick?</h3>

<u>The answer is B.</u>

C, D and E describe curved paths which indicate accelerated motion over time. Since the kick was “swift” the force on the puck, and therefore its acceleration was instantaneous. The horizontal motion in A is cancelled out, which would imply a force to stop it in the horizontal direction, which did not occur.

<h3>Vector A is directed northward and vector B is directed eastward. Which of the following vector addition diagrams best represent the addition of vectors A and B and the subsequent resultant?</h3>

The graphical representation of A directed northward, and B directed eastward. <u>The vector representing a b most closely</u> is by adding the tail of one of the vectors to the head of the other vector.

Looking our options the answer will be (E).

<h3>Two metal balls are the same size but one weighs twice as much as the other. The balls are dropped from the roof of a single story building at the same instant of time. The time it takes the balls to reach the ground below will be:</h3>

The answer is about the same for both balls. For more explanations go to brainly.com/question/14173803

<h3>A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground, and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are):</h3>

The answer is "an almost constant downward force of gravity only." For more explanations, go to brainly.com/question/19578722

<h3>An elevator is being lifted up an elevator shaft at a constant speed by a steel cable as shown in the figure below. All frictional effects are negligible. In this situation, forces on the elevator are such that:</h3><h3>(A) the upward force by the cable is greater than the downward force of gravity.</h3><h3>(B) the upward force by the cable is equal to the downward force of gravity.</h3><h3>(C) the upward force by the cable is smaller than the downward force of gravity.</h3><h3>(D) the upward force by the cable is greater than the sum of the downward force of gravity and a downward force due to the air.</h3><h3>(E) none of the above. (The elevator goes up because the cable is being shortened, not because an upward force is exerted on the elevator by the cable).</h3>

The answer is (B). Remember about constant speed.

<h3>Which path in the figure at right would the ball most closely follow after it exits the channel at "r" and moves across the frictionless table top?</h3><h3>a. Path 1</h3><h3>b. Path 2</h3><h3>c. Path 3</h3><h3>d. Path 4</h3><h3>e. Path 5</h3><h3 />

The answer is (B). Velocity in a circular motion is tangential. That's why it will remain in the same direction of tangent. It closely moves in straight line path so it follows the path B. Velocity

<h3>A student throws a ball to a friend which of the following causes the ball to fall downward</h3>

The answer is Gravity. Gravity caused the ball to fall.

<h3>The figure below shows a boy swinging on a rope, starting at a point higher than A. Consider the following distinct forces:</h3><h3>1. A downward force of gravity.</h3><h3>2. A force exerted by the rope pointing from A to O.</h3><h3>3. A force in the direction of the boy’s motion.</h3><h3>4. A force pointing from O to A.</h3><h3>Which of the above forces is (are) acting on the boy when he is at position A?</h3><h3>(a) 1 only.</h3><h3>(b) 1 and 2.</h3><h3>(c) 1 and 3.</h3><h3>(d) 1, 2, and 3.</h3><h3>(e) 1, 3, and 4.</h3>

The answer is A. Only the force of gravity and the tension force from the swing act on the person.

When the cannonball is fired from the cliff, it will most closely follow the path 2.

<h3>What is a projectile motion?</h3>

This a type of motion in which the projectile experiences the influence of Earth gravity causing the projectile take a parabolic  or curved trajectory.

The cannonball is an example of a projectile and its path of motion will be parabolic or curved.

From the given graph;

  • The path 1 is a linear path
  • The path is a parabolic path
  • The path 3-5 is linear and curved

Thus, when the cannonball is fired from the cliff, it will most closely follow the path 2.

Consider a loop of wire with a resistor. In the same plane, (with switch S closed) a long wire has a current I flowing from left
Ulleksa [173]

Solution :

The given figure is a loop of a wire with a resistor.

When the switch S is closed for long time and is suddenly opened, the direction of the induced current can be find out by using the rule of right hand screw. According to the right hand screw rule, the direction of the magnetic field at the loop is in the direction that points outwards. The strength of the current rapidly decreases as it is switch off and the magnetic flux that is linked with the loop wire will also decrease.

According to the Lenz's law, the direction of the induced current must be such $\text{that it opposes}$ the decrease in the magnetic flux.  It means the direction of the magnetic field must be outwards and also normal to the plane of the screen. The direction of the induced anti clockwise or from right to left in the resistance.

What is the least amount of time required for a given point on this wave to move from y = 0 to y = 12cm?
ale4655 [162]

Time t = ?

<span>When wave is moving from y = 0  to y =12 cm</span>

By using the formula,

y = 15cos [(π/12) t)] = 0,

cos [(π/12) t)] = 0 = cos (π/2), so, 

(π/12)t = π/2,

t = (π/2) (12/π) 

t = 12/2

<span>t = 6 sec</span>

<span>so 6 sec is the least amount of time required</span>
