Explanation:
It is given that,
Weight of a woman, W = 130 lb
The area of the heel,
The force acting per unit of area is called the pressure exerted on the underlying surface.
(a) Weight in newton, W = 578.26 N
Area of the heel,
Pressure,
or
P = 1795 kPa
(b) Since,
(c)
Hence, this is the required solution.
<h3><u>Answer;</u></h3>
A. If two in-phase waves arrive simultaneously at a point, their amplitudes add up.
<h3><u>Explanation;</u></h3>
- <u>According to the principle of superposition, when two waves of the same kind meet at a point in space, the resultant displacement at that point is the vector sum of the displacements that the two waves would separately produce at that point.</u>
- Interference involves the superposing of two or more coherent waves to produce regions of maxima and minima in space, according to the principle of superposition.
- Interference may be constructive or destructive; Constructive interference occurs when two or more waves arrive at the screen in phase with each other, such that the amplitude of the resultant wave is the sum of the amplitude of the individual waves.
- Destructive interference occurs when two or more waves arrive out of phase with each other and resultant wave has minimum amplitude.
Answer:
hey I know the answer for this
Explanation:
it will be reduce the speed of A
the answer is 7.
this is the exact answer.
if you don't like this answer means pls comment me
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
I think the correct answer from the choices listed above is option A. The strength of a gravitational force between two objects depends on mass and distance. These are the two factors the dictates the strength of the gravitational force between objects.
