Answer:
A simple way to state Newtons first law is:
For every action force, there is a reaction force which is equal in magnitude and opposite in direction.
Answer: You throw an object upwards from the ground with a velocity of 20m/s and it is subject to a downward
acceleration of 9.8 m/s2. How high does it go?
Given Formula Set up Solution
vi=20 m/s
vf=0 m/s
a=-9.8 m/s2
x=?
vf
2 = vi
2 + 2a x (0 m/s)2= (20 m/s)2 + 2 (-
9.8 m/s2) x
x=20.4 meters

Answer:
The correct option is;
A. Circular
Explanation:
Some of the light that impinges on the surface are reflected and the rest are transmitted to a different medium
At the surface of the next medium also, some of the light are transmitted while the others are reflected and refracted through the first medium
The speed of light (and hence the wavelength and color) refracted through the thin film is changed as the distance the refracted light travels through the thin film is increased as we move away from the point directly in the front view to some distance as the reflected light path from those distance to the eye is increased due to their inclination giving them a different wavelength which are all equal at a radial distance from the eye hence forming a circular fringes.
Answer:
The distance is 0.53 m.
Explanation:
Given that,
Target distance = 100.0 m
Speed of bullet = 300 m/s
We need to calculate the total time
Using formula of time
Put the value into the formula
Now, consider vertical motion of bullet.
Initial velocity of bullet in vertical direction = 0 m/s
We need to calculate the vertically distance
Using equation of motion
Put the value in the equation
Hence, The distance is 0.53 m.
The most common symbol for momentum is p
