Answer:
Explanation:
The tension in the cable would be then equal to the gravitational force that keeps the Moon in circular orbit around the Earth. So, we just need to calculate the magnitude of this force, which is given by:
where:
is the gravitational constant
is the mass of the Moon
is the mass of the Earth
is the distance between the Earth and the Moon
Substituting these numbers into the formula, we find:
You clearly identified the pole you're talking about as the
"north-seeking" pole. Assuming your integrity and sincerity,
we would then naturally expect that pole to seek north, and
point to Earth's north magnetic pole.
I'm confident in this answer also because I have several of
these devices hanging from the ceiling of my office, and I can
attest to the fact that on most clear days, they do in fact point
toward Earth's north magnetic pole.
Mitochondria which is in cells produce energy in complex organisms.
Answer:
Explanation:
Give that,
Mass of object
Ma = 40kg
Mb = 35kg
Velocity of mass A Va = 50m/s
Velocity of mass B Vb = 30m/s
Since after collision the two bodies stick together(inelastic collision), then, they will have a common velocity
Let assume common velocity V
So using conservation of linear momentum
Momentum before collision is equal to momentum after collision
P(before) = P(after)
Note P = mV and momentum is a vector quantity
So we assume, that the small mass is moving in the negative direction
P(before) = P(after)
Ma•Va —Mb•Vb = (Ma+Mb)V
40×50—35×30 = (40+35)V
950 = 75V
Then, V = 950/75
V = 12.67 m/s
The common velocity is 12.67 m/s
Answer:
Kinetic energy
Explanation:
Since kinetic energy is the energy an object has when it is moving, the answer is kinetic energy :)
