The dusting of hydrogen into helium. HOPE THIS HELPEDD
Answer:

Explanation:
The acceleration due to gravity on the surface of the Earth is given by:

where
G is the gravitational constant
M is the mass of the Earth
R is the radius of the Earth
Here we want to find the new Earth radius R' for which the gravitational acceleration at the surface, g', would be 3 times the current value of g:

So we would have

Solving the equation for R', we find

Answer: Objective Observations
Explanation: The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false
Wavelength = (speed) divided by (frequency) = 10/0.5 = <span>20 </span>
Work = Force * distance
He's going up an incline but pushing parallel to the ground. Draw out a diagram to show what's going on. )
Work = force* distance*Cos(incline angle)
60 N force * 10 meters * cos(30)
= 519.61 J
