And it cannot move anything that is not magnetic
(I hoped this helped ;) And good luck!)
Answer:
5.73kg
Explanation:
Given data
Height = 8m
Potential Energy = 450J
Required
The mass of the object
From the following expression
PE=mgh
we can substitute g= 9.81m/s^2 and the other parameters to get mass m
450= m*9.81*8
450= m* 78.48
m= 450/78.48
m= 5.73kg
Hence the mass is 5.73kg
Answer:
The center mass (Xcm) of the two mass = (M₁X₁ + M₂X₂)/(M₁ +M₂)
Explanation:
let the first mass = M
let the position of second = M
The FFA is the Future Farmers of America. It has no authority in aeronautical matters.
4.5m/s you count the number between 6 and 14 and get 9 do 9 divided by 2 and you get 4.5 m/s increase. hope this helps.
