Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,
Where,
J = impulse = 3.6 Ns
F = Force = 600N
= Time = ?s
Putting the values in above equation, we get:
t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
When a small lab cart collide with a large mass then during the collision two bodies will remain in contact and then apply the contact force on each other
This contact force is always equal on two bodies in magnitude and also it is normal or perpendicular to the contact surface.
This will always follow Newton's III law as per which every action has equal and opposite reaction.
So this contact force will not depend on the mass or any other factor but it will remain same on two colliding bodies.
So here the correct answer would be
<em>They both experience the same magnitude of the collision force.
</em>
We can calculate for the volume by taking the ratio of
mass and density, that is:
volume = mass / density
A. when mass = 5.5 kg = 5500 g; density = 1.60 g/cm^3
volume = 5500 g / (1.60 g/cm^3)
volume = 3,437.5 cm^3
Taking the significant digits:
volume = 3,400 cm^3 = 3.4 L
B. when mass = 4.9 kg = 4900 g; density = 1.36 g/cm^3
volume = 4900 g / (1.36 g/cm^3)
volume = 3,602.94 cm^3
Taking the significant digits:
<span>volume = 3,600 cm^3 = 3.6 L</span>
Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets<span>. The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by </span>massive layers of gas<span>. Made almost entirely of hydrogen and helium, these planets do not have solid surfaces.</span>
