that we only see one side of the moon because the moon rotates around the Earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth.

Greeley [361]

Answer:

A hypothesis predicts the value of a dependent variable given an independent variable:

If a person weighs 50 kg (independent variable) the weight hypothesis predicts that W = 50 * 9.8 = 490 N (the dependent variable)

So those three should be present in an investigation

A pilot performs an evasive maneuver by diving vertically at 270. If he can withstand an acceleration of 9.0 's without blacking

mamaluj [8]

Answer:

The pilot must be began at an altitude of 826.53 m to avoid crash into the sea.

Explanation:

Given that,

Velocity = 270 m/s

Acceleration = 9.0g s

We need to calculate the altitude

Using formula of centripetal acceleration

$a_{c}=\dfrac{v^2}{r}$

$r=\dfrac{v^2}{a_{c}}$

Where, v = velocity

r = altitude

a = acceleration

Put the value into the formula

$r=\dfrac{270^2}{9.0\times9.8}$

$r=826.53\ m$

Hence, The pilot must be began at an altitude of 826.53 m to avoid crash into the sea.
