Answer:

Some bright and dark regions would be observed on the white sheet of paper because of the slits of the card.

Explanation:

A white surface is one that reflects all colors of light hitting it. If a colored light is used, the surface would reflect the exact color of the light. When a red light is shown on a white surface, it would reflect the color and looks red.

A ray of light is the path through which lighr travels and it can combine to form a beam. These rays always travels in a straight path during propagation. When light passes through a card with more than a slit (a hole or opening through with the rays of light can pass), constructive interference would occur, a bright and dark regions would be formed. The bright regions are produced due to interfernce of trough-to-trough and crest-to-crest, while the dark region is produced due to interference of trough-to- crest.

On the white sheet of paper, bright and dark regions would be observed because of the slits of the card.

Vectors A and B lie in the xy ‑plane. Vector A has a magnitude of 17.1 and is at an angle of 150.5∘ counterclockwise from the +x

IRINA_888 [86]

Answer:

A = -14.87 i ^ + 8.42 j ^ + 0 k ^

B = -25.41 i ^ -12.0 j ^ + 0 k ^

Explanation:

For this exercise let's use trigonometry by decomposing to vectors

vector A

module 17.1 with an angle of 150.5 counterclockwise.

Sin 150.5 = $A_{y}$ / A

cos 150.5 = Ax / A

A_{y} = A sin 150.5 = 17.1 sin 150.5

Aₓ = A cos 1505 = 172 cos 150.5

A_{y} = 8,420

Aₓ = -14.870

the vector is

A = -14.87 i ^ + 8.42 j ^ + 0 k ^

Vector B

$B_{y}$ = 28.1 sin 205.3

Bₓ = 28.1 cos 205.3

B_{y} = -12.009

Bₓ = -25.405

the vector is

B = -25.41 i ^ -12.0 j ^ + 0 k ^

PLEASE HELP!!!!!!!!!!!!!!!!

The correct answer is - It is the part of the ocean where new crusts are formed.

The place marked with A on the map is the place in the ocean where the new crust is formed. That is a place where there's a divergent plate boundary, or rather a place where the tectonic plates are moving away from one another. The gap and cracks left between them are easy target for the magma from the mantle to penetrate towards the surface. As the magma reaches the ocean floor it starts to cool off very quickly, creating new crust, and slowly making a very large underwater mountain range known as mid-ocean ridge.

A person hits a 45-g golf ball. The ball comes down on a tree root and bounces

Verizon [17]

Answer:

Maximum height, h = 10 m

Explanation:

It is given that,

Mass of golf ball, m = 45 g = 0.045 kg

The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.

We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,
