We know, f = ma
Here, m = 100 kg
a = 20 m/s²
Substitute their values,
f = 100 * 20
f = 2000 N
In short, Your Answer would be 2000 N
Hope this helps!
Answer:
45 N
Explanation:
The question can be solved by using Newton's second law:
F = ma
where
F is the net (unbalanced) force on the cyclist
m is the mass of the cyclist
a is his acceleration
In this problem:
m = 50 kg
Therefore, the unbalanced force is
The smallest particle of an element that still retains all the element's properties is a(n) _____. atom .... but many particles inside
Answer:
a = v^2 / R centripetal acceleration
R = v^2 / a a at the surface of earth is 9.8 m/s^2
R = (90 m/s)^2 / 9.8 m/s^2 = 827 m
Radiation can pass through any phase of matter.
Examples:
Light, radio, heat, and X-rays, all pass through glass (solid),
water (liquid), and air (gas) very easily.
(Moreover, I would be remiss if I failed to point out in addition that
microwave radiation passes through meatloaf and coffee with only
partial attenuation due to absorption.)
