If you exert a horizontal force of 200 N to slide a crate across a factory floor at constant velocity, how much friction is exer
ted by the floor on the crate?
1 answer:
Answer:
200 N
Explanation:
Applied force, F = 200 N
Let the friction force is f.
By use of Newton's second law
Net force = mass × acceleration
F - f = m × a
Here acceleration a is zero as crate moves with constant velocity.
So, F - f = 0
f = F
Friction force = 200 N

Answer:
The correct answer is "6666.67 N".
Explanation:
The given values are:
Mass,
m = 0.100
Relative speed,
v = 4.00 x 10³
time,
t = 6.00 x 10⁻⁸
As we know,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
B. so light can shine through it from below.
Answer:
Higher its Energy
Explanation:
The kinetic energy of the car is A.) 0.466 J
You get a more low sound.
Conversely, when the wavelength becomes shorter you get a more treble sound.
