Answer:
Forces between molecules
Explanation:
The tensions between molecules are the characteristic that explains variances in the specific heat capacity of two substances.
This means that a substance's specific heat capacity will increase or be higher the closer its atoms are bound together. As a result, it differs for the different states of matter, such as solid, liquid, and gas.
Answer:
option A
Explanation:
The correct answer is option A
Reproducible experiment is a specific experimentally produced value is said to be reproducible when there is a fair degree of consistency between measurements or observations done by different people at different locations on duplicate specimens — that is, if the test value is determined to be of great accuracy.
hence, a scientific hypothesis can be disproved with one reproducible experiment.

</h2><h3>kinetic energy is given as</h3>
KE = (0.5) m v²
given that : v = speed of the bottle in each case = 4 m/s when m = 0.125 kg
KE = (0.5) m v² = (0.5) (0.125) (4)² = 1 J
when m = 0.250 kg KE = (0.5) m v² = (0.5) (0.250) (4)² = 2 J
when m = 0.375 kg KE = (0.5) m v² = (0.5) (0.375) (4)² = 3 J
when m = 0.0.500 kg KE = (0.5) m v² = (0.5) (0.500) (4)² = 4 J

length of hour hand is 2.7m
length if minute hand is 4.5m
And Moment of inertia of a rod about its one of a end 
for hour hand is
Angular speed for minute hand 
Angular moment(L) is given 
For hour hand
Answer:
no change
Explanation:
The Newton's Second Law of motion states that when an unbalanced force is applied to an object, it causes an accelerated motion in the object, in the direction of the unbalanced force. So, if there is no unbalanced force, then there is no motion. In this case both the forces have same magnitude and opposite direction. Therefore, the unbalanced force will be zero:
Unbalanced Force = Upthrust - Weight
Unbalanced Force = 2448 N - 2448 N
Unbalanced Force = 0 N
hence, there will be no motion in the vertical direction. Therefore, the correct option is:
<u>no change </u>
