The speed of a 4-kg ball with a momentum of 12 kg m/s is

Physics

alisha [4.7K]3 years ago

Answer:

3 m/s

Explanation:

The momentum of an obejct is given by

p=mv

where

m is the mass of the object

v is the velocity of the object

For the ball in this problem, we know:

p = 12 kg m/s is the momentum

m=4 kg is the mass

Therefore, we can re-arrange the equation to find v, the velocity of the ball:

v=\frac{p}{m}=\frac{12 kg m/s}{4 kg}=3 m/s

Which tem decorbes the perceived frequency of a sound wave?
JulsSmile [24]

Pitch

Explanation:

The pitch of a sound wave is the perceived frequency of a sound wave.

The quality of sound that makes it discernible to the ear is the pitch.

  • Sound wave is a longitudinal wave that is transmitted by series of rarefaction and compression.
  • Pitch helps to distinguish between the different sound qualities.
  • Pitch is how high or low sound is perceived.

Part B
Katena32 [7]

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

A Honda Hawk motorcycle and its rider with a combined mass of 450 kg travels around a curve of radius 106 m with a speed of 18 m
umka21 [38]

Answer: coefficient of static friction

= 0.31

Explanation: Since they negotiate the curve without skidding, the frictional force (F1) equals the centripetal force (F2).

F1= uN

F2 = M*(v²/r)

M is the combined mass 450kg

V is the velocity 18m/s

r is the radius 106m

N is the normal reaction 4410N

u is the coefficient of static friction

Making u subject of the formula we have that,

u = {450*(18²/106)} /4410

=1375.47/4410

=0.31

NOTE: coefficient of friction is dimensionless. It as no Unit.
