Choose the best explanation from among the following: A. It takes more energy to go from the Moon to the Earth because the Moon

is orbiting the Earth. B. The escape speed of the Moon is less than that of the Earth; therefore, less energy is required to leave the Moon. C. The situation is symmetric, and hence the same amount of energy is required to travel in either direction.

Answer:

B. The escape speed of the Moon is less than that of the Earth; therefore, less energy is required to leave the Moon.

Explanation:

Since the speed required to escape from the gravitational attraction of the Moon is less than the speed required to escape from the gravitational attraction of the Earth, less energy is required to travel from the Moon to the Earth, than is required to travel from the Earth to the Moon. This is because the kinetic energy is directly proportional to the square of the velocity.

Why can light microscopes produce images in their natural color
Fiesta28 [93]

Answer:

The electron microscopes  are uses the electron to produce the image of the any object.The area where the electron passes then that area  appeaser white but on the other hand where the electron does not pass that area appears black.But this does not give any information about the color of light it shows only white and black areas.We also know that color is the property of photons ( light).So the microscopes does not produce color of the image.

A 2.5 kg block is launched along the ground by a spring with a spring constant of 56 N/m. The spring is initially compressed 0.7
Norma-Jean [14]

vf ^2 = kx^2/m = 56(0.75)^2 / 2.5 = 12.6


Therefore, v= 3.5 m/s.

A parallel plate capacitor fully charged to voltage V is connected to the battery (the voltage on the plates remains fixed). If
Papessa [141]

Charge will decreases.

A parallel plate capacitor when it is fully charged to voltage V is given as:

                    C = Q/V

The capacitance of parallel plate capacitor with two plates of Area A separated by distance d and no dielectric material between plates is

                    C = ε₀ A /d

since from above equation it shows C is proportional to Q and also C is inversely proportional to distance d.

So, ATQ when d increases C will decrease which in result decreases charge on the capacitor.

Thus,  Charge will decrease.
