An object in space is initially stationary relative to the Earth. Then, a force begins acting on the object, starting with a for

ce of 0 N, and increasing at a uniform rate until the magnitude of the force is 38 N after the force has acted for 10 s. The body has a mass of 15 kg. What is the speed of the object at 10 s?

A parallel-plate capacitor is connected to a battery and becomes fully charged. The capacitor is then disconnected, and the sepa
AnnZ [28]

Answer:

Increases

Explanation:

The expression for the capacitance is as follows as;

C=\frac{\epsilon _{0}A}{d}

Here, C is the capacitance, \epsilon _{0} is the permittivity of free space, A is the area and d is the distance between the parallel plate capacitor.

It can be concluded from the above expression, the capacitance is inversely proportional to the distance. According to the given problem, the capacitor is disconnected from the battery and the distance between the plates is increased. Then, the capacitance of the given capacitor will decrease in this case.

The expression for the energy stored in the parallel plate capacitor is as follows;

E=\frac{Q^{2}}{2C}

Here, E is the energy stored in the capacitor, C is the capacitance and Q is the charge.

Energy stored in the given capacitor is inversely proportional to the capacitor. The charge on the capacitor is constant. In the given problem, as the distance between the parallel plates is being separated, the energy stored in this capacitor increases.

Therefore, the option (c) is correct.

Through which medium will sound have slowest speed? Group of answer choices
Vinvika [58]

Answer: Air

Explanation: Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.  Air and hydrogen have nearly the same elastic properties, but the density of hydrogen is less than that of air. Sound thus travels faster (about 4 times as fast) in hydrogen than in air.

lesya [120]

Answer:

Objects that have like charges attract each other.

Objects that have opposite charges repel each other.

When fur is rubbed on the balloon electrons move from the balloon to the fur.

This is because the balloon's material is an insulator.

Electrons have negative charge.

Protons have a positive charge.

neutrons have no charge.
