Answer:
B. MASS & MATTER
Explanation:
Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.
A wave with a greater amplitude carries more energy to wherever it goes.
Answer:c
Explanation:
When an object is performing simple harmonic motion then time period is given by measuring the time period take by object to return its initial position.
Thus we can say that it also valid for maximum position thus period is the correct is answer for this problem.
Time Period of oscillation for spring mass system is
Answer:
electrical 'pressure' measurement
Explanation:
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
