Answer:
Increases
Explanation:
Due to an increase in temperature, molecules within the medium will vibrate more vigorously, meaning that the rate of chemical reactions generally increases with temperature due to an increase in kinetic energy. Because sound is a form of kinetic energy, it is safe to assume that the speed of sound waves increases with temperature.
Answer:
Electric field, in the direction of gravity.
Explanation:
Given that,
Mass of the ball, m = 0.15 g
Charge on the ball,
The ball is placed inside a uniform electric field, and is suspended against the force of gravity such that,
The electric field will be acting in the direction of gravity. Hence, this is the required solution.
