What would happen if the moon were twice as big

Answers

Answer 1

Answer: The universal gravity formula is F = G(Me)(Mm)/r^2. Lets use this formula to help us calculate what would happen if the Moon was twice as big.
Mn = new mass = 2*Mm
Fn = G(Me)(Mn)/r^2
Fn = G(Me)(2Mm)/r^2
Fn = 2*G(Me)(Mm)/r^2
Fn = 2*F
So 2 times the force it was before. The force should be the same, but you never know the moon and space as well know it can work in very mysterious ways.

Answer 2

Answer: The force is the same force the moon pulls on the earth is the same as the earth pulls the moon

Mary walked north from her home to Sheila's home, which is 4.0 kilometers away. Then she turned right and walked another 3.0 kilometers to the supermarket, which is 5.0 kilometers from her own home. She walked the total distance in 1.5 hours. What were her average speed and average velocity?

Answers

The answer is speed: 4.7 km/h, velocity: 3.3 km/h.

Distances and time are given:
d1 = 4 km
d2 = 3 km
d3 = 5 km
t = 1.5 h

The speed can be expressed as a distance (d) divided by time (t). The average speed (s) is total distance travelled divided by time:
s = (d1 + d2)/t = (4+3)/1.5 = 7/1.5 = 4.7 km/h

The average velocity (v) is total displacement (d₁) from the starting point divided by time. Since Mary's starting point was home, and she walked to the supermarket, which is 5.0 kilometers from her own home, her displacement is 5 km:
v = d₁/t = 5/1.5 = 3.3 km/h

A train travels with a constant speed of 36 miles per hour. How far can it travel in 1 hour 30 minutes?

Answers

Answer: 54 miles in 1hr 30min

Explanation:

The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes

One particular confound for the use of an adoption study of heritability is the phenomenon of _____ placement, in which a child is placed in a home that is similar to the home of the biological parents.A) unilateral
B) forced
C) matched
D) selective

Answers

Answer:

D) selective

Explanation:

The selective placement in the adoption studies refers to practice by which the adoption agencies tend to match some definite characteristics of the adopted child's adopted parents than that of child's biological parents.

It results in the correlation of the environments between the biological relatives raised in two different homes.

For example, when the child is placed in a home which is similar to the home of the biological parents.
