Answer: The correct answer is option (C).
Explanation:
As it is given in the problem, the path of a meteor passing Earth is affected by its gravitational force and falls to Earth's surface. Another meteor of the same mass falls to Jupiter's surface due to its gravitational force.
According to Newton's law of universal gravitational, every particle attracts every other particles in the universe with the gravitational force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The Jupiter is the most massive planet in the solar system. It is also the largest planet in the solar system. The gravity of Jupiter on its surface is 2.4 times that of surface gravity of the Earth.
If a person weighs 100 pounds on the Earth then he would weigh 240 pounds on Jupiter.
Therefore, the correct answer is option (C), the meteor falls to Jupiter faster due to its greater gravitational force.
Answer:
Nuclear fission of U235 to Kr92 and Ba 141.
Explanation:
Nuclear fission is the spantenous disintegration or breaking down of a big atom into smaller nucleus with the release of huge amount of energy. It involves the artificial transmutation of a heavier nucleus by bombardment with other rasuiactive particles.
Answer:
the magnitude of the acceleration a = 0.43 m/s²
Explanation:
m = 58kg
F = 25 N
a = ?
recall that F = ma
=> a = F/m
a = 25/58
a = 0.43 m/s²
Answer:
The kinetic energy of the clam at a height of 5.0 m is 5.19 J and the speed of the clam at that height is 9.71 m/s.
<u>Explanation:
</u>
<em>Mechanical energy is constant throughout the travel</em>, we know that <em>mechanical energy is calculated by adding potential energy and kinetic energy</em>. Potential energy =
,
Kinetic energy =
and Mechanical energy =
Kinetic energy is zero at initial point. Now mechanical energy of clam with m=0.11kg,g=9.81
,h=9.8 m is = 0.11×9.81×9.8 = 10.58 J.
Mechanical energy of clam at a height of 5.0 m =
=
. We know that mechanical energy is constant hence, <em>mechanical energy of clam at height 9.8 m is equal to mechanical energy at height 5.0 m</em>. This is represented as following
10.58 =
10.58 – 5.39 =
5.19 =
kinetic energy of the clam is 5.19 J.
Now speed of the clam at height 5.0 m is 5.19 =
94.36 =
= 9.71 m/s. The speed of the clam is 9.71 m/s.
Answer:
a.) F = 3515 N
b.) F = 140600 N
Explanation: given that the
Mass M = 74kg
Initial velocity U = 7.6 m/s
Time t = 0.16 s
Force F = change in momentum ÷ time
F = (74×7.6)/0.16
F = 3515 N
b.) If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0080 seconds
Change in momentum = 74×7.6 + 74×7.6
Change in momentum = 562.4 + 562.4 = 1124.8 kgm/s
F = 1124.8/0.0080 = 140600 N
