Answer:
Newton's Second Law is applied because of the acceleration caused by natural forces as the egg is plummeting to the earth. And the amount of acceleration the egg has will be largely affected by the amount of force Mr. Baker uses to hurl the egg to the ground.
Explanation:
hope that helps
Answer:
a = 2 m/s2
Explanation:
we know from newtons 2nd law
F = ma.
we also know that from hookes law we have
F = kx
equate both value of force to get value of acceleration
kx = ma,
where,
k is spring constant = 8.0 N/m
x is maximum displacement 0.10 m
m is mass of object 0.40 kg
a = \frac{kx}{m}
= \frac{8 *0 .10}{0.40}
a = 2 m/s2
Answer:
A freely suspended magnet comes to rest along the N-S direction.
Explanation:
-Irrespective of direction of suspension, the bar eventually comes to rest at earth's N-S direction.
-Bar end that points to Earth's north is called the <em>North Pole</em>. Bar end that point's to earth's south is called the <em>South pole</em>.
-The reason for this default positioning is called the Directive Property. This is because earth acts as an external magnetic field.
Answer:
No. Your friend will not hear the clap when he/she sees it.
Explanation:
It takes time for sound waves to go through a large area. It takes longer if people are in the area rather than it is empty.
Answer:
A. Refer to the figure.
B. The net force acting on the crate is
C. We should first find the acceleration of the crate using the following kinematics equation:
Mass of the crate can be found by Newton’s Second Law:
