Answer:

Explanation:

Friction is the force that you feel whenever you try to drag an object across a surface. Like a box along the floor, or your hand across a counter-top. It requires two objects to be in direct contact with each other (don't worry about air friction AKA "drag").

Is there any change in mass of substance after it changes its state? Explain with an example

Flura [38]

Answer:

Explanation:

When a substance changes its state , there will not be any change in the mass of substance . For example , if we change 100 grams of water (liquid) to ice(solid) , the mass of ice will be same i.e., 100 grams . This shows there is no change in the mass even if a substance changes its state.

Increasing the mass attached to a spring will decrease the angular frequency of its vibrations. True or False

Scrat [10]

Answer:

decreases

Explanation:

The angular frequency of the mass is given by

$\omega =\sqrt{\frac{k}{m}}$

where, k is the spring constant and m be the mass of the body which is doing oscillations.

if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.
