Please help me with my physics! Provide explanation

Answer 1

Answer: The answer is C.

If two objects interact and become charged, there must be an electron transfer.

"Became positively charged" means there are more protons than electrons in an atom.

And protons can't move, so the positive charged material lost electrons.

A and B are wrong because the protons can't move (at least not that easy).

D is saying the protons are "created" which is impossible.

The displacement vector from your house to the library is 520 m long, pointing 40 ∘ north of east.What are the x-component (x-axis is directed from west to east) of this displacement vector?What are the y-component (y-axis is directed from south to north) of this displacement vector?

Answers

Answer:

398.3 m, 334.2 m

Explanation:

The magnitude of the displacement vector is

v = 520 m

And its direction is

$\theta=40^(\circ)$

measured as north of east.

The x-component of this vector is given by:

$v_x = v_0 cos \theta = (520)cos 40^(\circ)=398.3 m$

While the y-component is given by

$v_y = v_0 sin \theta =(520)sin 40^(\circ)=334.2 m$

Final answer:

The x-component of the displacement vector (east-west direction) is approximately 398 m and the y-component (north-south direction) is approximately 334 m.

Explanation:

Displacement vectors contain both magnitude and direction information. In the case of a displacement vector 520 m long, pointing 40 degrees North of East, we can break it down into x and y components using trigonometric functions, specifically cosine and sine.

For the x-component (east-west direction), we can use the cosine function because it gives us the adjacent side in a right triangle, which is the east-west direction in our case. Therefore, the x-component will be:
520 m * cos(40) = 398m (rounded to nearest unit).

For the y-component (north-south direction), we can use the sine function because it gives us the opposite side in a right triangle, which is the north-south direction in our case. Hence the y-component will be:
520 m * sin(40) = 334 m (rounded to nearest unit).

Which statement is true according to hooke's law? a. as the force on a spring increases, the spring's length remains unchanged.

b. the distance a spring stretches has nothing to do with how much force is applied to it.

c. as the force on a spring increases, the distance it stretches increases.

d. as the force on a spring increases, the distance it stretches decreases.

Answers

Answer: option c. as the force on a spring increases, the distance it stretches increases.

Explanation:

Hooke's Law relates the force (F) applied on the spring and extension (x) of the spring:

F = - k x

Where, k is the spring constant.

as the force on a spring increases, the distance it stretches increases but it is limited by its elastic limit. The negative sign means that spring force is a restoring force which means that the stretch of the spring is in opposite direction to force.

The answer is
c. as the force on a spring increases, the distance it stretches increases
