Larger molecules will move slower and smaller molecules will move faster. Did this answer your question?
Answer:
direction does the axis of rotation tilt toward after the blow is the z- direction
Explanation:
This is because
Due to the blow, there is a impulse imparted on the ball which gives a change in linear momentum () in the x direction
Thus When cross product of momentum in x direction is taking with r vector, we will get resultant in z direction. Hence change in angular momentum will be z direction.
Answer:
multiple is the product of any quantity and an integer. where a sub multiple of a main unit is a unit, named by prefixing the main unit, defined as the quotient of the main unit by an integer
Explanation:
Answer:
further tightening is required.
Explanation:
The beat created / sec = difference of frequencies
Initial beat heard = 2
so difference of frequencies = 2
after tightening beat heard = 1
difference of frequencies decreases because frequency of tuning fork was higher than piano sound.
on further tightening difference decreases because tightening increases the frequency of piano hence further tightening is required for resonance.
Answer:
It acts in the direction opposite of motion.
Explanation:
The sliding friction is the one offering resistance to motion of the sliding cereal box.This force is created between the box and the tabletop that are sliding against each other.The sliding friction is proportional to the weight of the cereal box when pushed on the horizontal tabletop.We can apply the Newton's second law of motion to describe this motion, where force is a product of mass and acceleration.When the object is massive, the sliding friction force experienced is high thus sliding happens slowly.
