Answer:
Part a)
Part b)
Explanation:
As per momentum conservation we know that there is no external force on this system so initial and final momentum must be same
So we will have
Part b)
By equation of kinetic energy we have
Answer:
Using the data in the table scientists, students, and others that are familiar with the periodic table can extract information concerning individual elements. For instance, a scientist can use carbon's atomic mass to determine how many carbon atoms there are in a 1 kilogram block of carbon.
Explanation:
HOPE THIS HELPS LIKE AN RATE PLZ
F = ma (force = mass x acceleration)
So the car’s mass affects the amount of force, changing how it would roll down a ramp, I think.
Answer:
False
Explanation:
Vector has a magnitude and direction.
A scalar is just a magnitude or size.
A difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force. Please mark me as a brainiest!!!
