1. ### Floating object on the Earth and the Moon.

The question is: The standard unit of measurement of force is the newton (N). It is the force needed to accelerate a mass of 1kg at 1 m/s^2 . On Earth's surface, a mass of 1 kg requires a force of 9.8 N to counteract the acceleration due to gravity of 9.8 m/s^2 downward. Multiplying the mass by...
2. ### If the sun set below your western horizon about 2 hrs ago, and the moon is barely ??

If the sun set below your western horizon about 2 hrs ago, and the moon is barely visible on the eastern horizon, what phase would the moon be in at this and location? new moon 3rd quarter full moon waning gibbous waning crescent waxing crescent 1st quarter waxing gibbous
3. ### Figure 1 shows Earth, the Sun, and five different possible positions for the Moon...?

Figure 1 shows Earth, the Sun, and five different possible positions for the Moon during one full orbit. It is important to recall that one half of the Moon’s surface is illuminated by sunlight at all times. For each of the five positions of the Moon shown below, the Moon has been shaded on one...
4. ### if the moon is a full moon when it rises in the evening, which of the phases will it?

if the moon is a full moon when it rises in the evening, which of the phases (shown below A-H) will it be when it sets?
5. ### Miles From Moon to Earth

One light-year is the distance light travels in a 365-day year. The speed of light is about 186,282.4 miles per second. Light from the moon to earth takes 1.25 seconds. How many miles is the moon from the earth? Express answer in scientific notation.

1 ) You are talking by interplanetary telephone to a friend who lives on the Moon. She tells you she has just won 1 newton of gold in a contest. Excitedly, you tell her that you entered Earth's version of the same contest and also won 1 newton of gold who is richer ? and why ? a)your friend...
7. ### Estimating distance of moon from its angular size and diameter.

The diameter of the moon is about 3500 kn. Its apparent size is about 0.0087 radians. About how far is it from Earth
8. ### Diameter of the Moon

The full moon subtends an angle of 1/2 degrees. The moon is 240,000 miles away. Find the diameter of the moon.
9. ### Stuck on a mechanics sum in moon's gravity:help:

The moon can be modeled as a sphere of radius 1740 km and mass 7.44*10^22 kg. A rocket of mass m is fired vertically from the surface of the moon with speed 1.5 km/s. It may be assumed that all forces on the rocket other than the gravitational attraction of the moon can be ignored. (c) Find...
10. ### image of the moon

Formulas are \frac{1}{f}=\frac{1}{di}+\frac{1}{do} \frac{hi}{ho}=\frac{-di}{do} F stands for focal point, di is distance to the image, do is distance to the object, hi is height of the image and ho is height of the object. \frac{4.5*10^-5}{3500}=\frac{-di}{380000} f=-4.88*10^-3...
11. ### Effect of moon..

I have a test next week... The moon pulls on the earth with one-sith the force that the earth exerts on the moon. a) true b) false
