Select all of the following that equal an impulse of 10 units A).Force = 20, time = 1/2

Physics
1 answer:
NNADVOKAT [17]3 years ago
4 0

Answer:

A, C and D

Explanation:

The impulse is defined as the product between the force (F) and the time of the collision (t):

I=Ft

Let's apply the formula to calculate the impulse for each situation:

A) I=Ft=(20)(\frac{1}{2})=10

B) I=Ft=(3)(4)=12

C) I=Ft=(5)(2)=10

D) I=Ft=(10)(1)=10

We see that the situations in which the impulse is equal to 10 units are:

A, C and D

In which direction does the electric field point at a position directly north of a positive charge?
navik [9.2K]

Answer:

B. South

Explanation:

An electric field can be defined as the amount of electric force per unit charge. The direction of the electric field can be determined by the motion of a positive test charge under the electric force.

The direction of electric field is radially outward for a positive charge and radially inward for a negative charge. Thus, for the electric field points toward SOUTH at a position directly south of a positive charge.

A hockey player uses a hockey stick to hit a puck such that the stick provides an applied force on the puck The puck travels for
Norma-Jean [14]

Answer:

Explanation:

Let's analyze the situation presented in order to know which answer is correct.

When the stick collides with the puck, it exerts a force for a certain time and discants. / After this time the horizontal force decreases to zero and the disk continues to move by the action of the initial velocity on the x axis and the acceleration of gravity on the y axis.

Therefore, after the collision, the only force that acts on the disk is the gravitational attractive force (WEIGHT), directed on the axis and in a negative direction.

The correct answer is:

C)           Since there is no frictional force exerted on the puck, a normal force is not exerted on the puck, but the gravitational force is exerted on the puck

Explain the term diffraction​
kow [346]

Answer:

the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced. Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.

Explanation: FYI I gave you the def and what it refers to BTW
