Answer:
57 eV
Explanation:
= separation between the plates = 4.9 mm = 0.0049 m
= Potential difference between the plates = 57 Volts
= magnitude of charge on proton = 1 e
= Kinetic energy of the proton
Using conservation of energy
Kinetic energy lost = Electric potential energy gained
Add more of the liquid because the length is more redemption.
Answer:
we could use the formula, v=u+at,
65=25+a (10), a=4 , since the motion is declerating we have a=-4 m/s2
Answer:
1.38*10^18 kg
Explanation:
According to the Newton's law of universal gravitation:
where:
G= Gravitational constant (6.674×10−11 N · (m/kg)2)
ma= mass of the astronaut
mp= mass of the planet
so:
(A)energy lost in the lever due to friction
(C)
visual estimation of height of the beanbag
(E)position of the fulcrum for the lever affecting transfer of energy
