Answer:
No
Explanation:
Unless there are other external forces, this will never be true. Because according to energy conservation, potential energy will be converted to kinetic energy as the ball falls down (so it loses height and gain speed). And vice versa, kinetic to potential when it bounces back. So the potential energy after must be the same (or smaller if losing heat to external environment), so it can only get the the same height or less, but not more.

Answer:
V = 365643.04 m/s
Explanation:
mass of the sun = 1.99 x 10^{30} kg
mass of M1 = mass of M2 = 6.95 solar mass = 6.95 x 1.99 x 10^{30} = 13.8305x 10^{30} kg
orbital period of each star (T) = 2.20 days = 2.20 x 24 x 60 x 60 =190,080 s
gravitational constant (G) = 6.67 x 10^{-11} N m2/kg2
orbital speed (V) = 
we need to find the orbital radius (r) before we can apply the formula above and we can get it from Kepler's third law, 
x k
where
- k =
(take note that π is shown as 
)
making r the subject of the formula we now have
(take note that π is shown as )
r = 1.38 x 10^{10} m
Now that we have the orbital radius (r) we can substitute all required values into the formula for orbital speed
orbital speed (V) =
V = 365643.04 m/s
Answer:
5.4kgm/s towards the hitter.
Explanation:
Given parameters:
Mass = 0.12kg
Velocity = 45m/s
Unknown:
Momentum of the baseball = ?
Solution:
To solve this problem, we must understand that the momentum of a body is the quantity of motion it possesses.
Momentum = mass x velocity
Now insert the parameters and solve;
Momentum = 0.12 x 45 = 5.4kgm/s towards the hitter.
Answer:
it leads to attraction, only because the total energy of the electron is negative. Therefore the electron moves closer to the proton rather than farther from it an attractive force.... Electrons are negatively charged and protons are positively charged.
