Answer:
Four times higher
Explanation:
F- G (m1 x m2)/ r^2
if r 1 = 2 and r 2 = 1 therefore F = G (m1 x m2)/ 1^2 is 4 times higher than
2^2 since G and m1 and m2 remained the same
Answer:
A) A buoy rises in the water as a boat speeds past.
Explanation:
The passing boat transfers energy in the form of a wave. Other options illustrate other physics concepts like gravity (falling egg) or Newton's law (for every action, there is an equal and opposite reaction).

This is the correct answer :)
Answer:
0.99kgm/s
Explanation:
Given parameters:
Initial momentum = 5.8kgm/s
Final momentum = 6.79kgm/s
Unknown:
Magnitude of the impulse applied to the baseball = ?
Solution:
To solve this problem;
The impulse applied to the baseball can be found by using the expression below:
Impulse = Final momentum - Initial momentum
Impulse = 6.79kgm/s - 5.8kgm/s = 0.99kgm/s
