Chapter 1: Q6DQ (page 424)

Since the moon is constantly attracted toward the earth by the gravitational interaction, why doesn’t it crash into the earth?

Short Answer

Expert verified

The moon does not crash into the earth due to centrifugal force opposite to gravitational interaction.

Step by step solution

01

Forces between Earth and Moon

The gravitational force acts between Earth and Moon due to the mass of both planets. This gravitational force attracts each planet towards itself.

The moon moves in a circular orbit around Earth. The moon produces a centrifugal force away from the Earth.

02

Reason for no crash between Earth and Moon due to gravitational interaction

The centrifugal force of the moon acts opposite to the gravitational force by which earth attracts the moon towards itself, so the moon does not crash with Earth by gravitational interaction.

Therefore, the moon does not crash into the earth due to centrifugal force opposite to gravitational interaction.

A cargo ship travels from the Atlantic Ocean (salt water) to Lake Ontario (freshwater) via the St. Lawrence River. The ship rides several centimeters lower in the water in Lake Ontario than it did in the ocean. Explain

Question- Neptunium. In the fall of 2002, scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237 is about 60 kg. The critical mass of a fissionable material is the minimum amount that must be brought together to start a nuclear chain reaction. Neptunium-237 has a density of 19.5 g/cm3. What would be the radius of a sphere of this material that has a critical mass?

An antelope moving with constant acceleration covers the distance between two points 70.0apart in6.00s. Its speed as it passes the second point is15.0m/s. What are (a) its speed at the first point and (b) its acceleration?

In March 2006, two small satellites were discovered orbiting Pluto, one at a distance of 48,000 km and the other at 64,000 km. Pluto already was known to have a large satellite Charon, orbiting at 19,600 km with an orbital period of 6.39 days. Assuming that the satellites do not affect each other, find the orbital periods of the two small satellites withoutusing the mass of Pluto.

The driver of a car wishes to pass a truck that is traveling at a constant speed of20.0m/s(about41mil/h). Initially, the car is also traveling at20.0m/s, and its front bumper is24.0mbehind the truck’s rear bumper. The car accelerates at a constant 0.600m/s2, then pulls back into the truck’s lane when the rear of the car is26.0mahead of the front of the truck. The car islong, and the truck is 21.0m long. (a) How much time is required for the car to pass the truck? (b) What distance does the car travel during this time? (c) What is the final speed of the car?
