When a flowerpot falls from a window sill 36.5 m
above the sidewalk, then the velocity of the flowerpot is 26.7 m/s.
From Newton's third equation of motion,
v^2 = u^2 + 2gh
where,
h is the height of the object or body from ground
u is the initial velocity of the body or object
v is the final velocity of the body or object
g is the acceleration due to gravity
Now, as we know that
Flowerpot is at rest. So, u = 0
g = 9.81m/s^2
h = 36.5m
By substituting all the values, we get
v^2 = 2 × 9.81 × 36.5
= 716.13
v = 26.7m/s
Thus, we concluded that when a flowerpot falls from a window sill 36.5 m
above the sidewalk, then the velocity of the flowerpot is 26.7 m/s.

Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
Answer:

Because the trial 2 student finger applied to largest force.
Answer:
X rays, ultraviolet light, green light, red light, infrared radio waves
Explanation:
The electromagnetic spectrum can be thought of as being arranged either in decreasing frequency or increasing wavelength. The full spectrum is as follows, from the shortest wavelength to the longest:
Gamma rays, X rays, ultraviolet light, violet light, indigo light, blue light, green light, yellow light, orange light, red light, infrared, radio waves, radar waves, microwaves, television waves, radio waves.
Answer:
We have to show surface area ,with few conditions that is by considering Force and Pressure to be respectively.
Explanation:
The atmospheric pressure is on Earth's surface.
The magnitude of the force exerted on a person by the atmosphere is .
Now to calculate surface area we can find it from and re-arranging it to.
So plugging the values,
Surface area
Hence from the above calculations we can say that surface area is .
So the surface area of an average person can be said to have , using the concept of pressure and force.
