The force between two celestial bodies is a Newtonian gravitational force.
It is also called Newton's law of universal gravitation. We can write it down mathematically in the following way:
We can see from this formula that gravitational force is <span>inversely proportional to the square of the distance between bodies.
The electrostatic force between two charges is Coulombs force. We can write it down like this:
</span>
This force is also inversely proportional to the square of the distance between interacting particles.
The nuclear force is a little bit more complicated. It can be expressed using the so-called Yukawa potential, which has the following form:
This interaction does not follow the inverse-square law.
The final answer should be 8.
Answer:
a) 20.81 J
b) 8.29 J
Explanation:
V = iR + L di/dt
where
i = a(1-e^-kt)
for large t
i = V/R
i = 24 / 9.4
i = 2.55 A
so
i = 2.55(1-e^-kt)
di/dt = 2.55 k e^-kt
24 = 24-24e^-kt + 6.4(2.55)k e^-kt
24 = 6.4(2.55) k
k = 24 / (6.4 * 2.55)
k = 24 / 16.32
k = 1.47 = R/L
so
i = 2.55(1-e^-(Rt/L))
current is maximum at great t
i max = 2.55 - 0
energy = (1/2) L i^2
E = (1/2)(6.4)2.55^2
E = 20.81 Joules
one time constant T = L/R and e^-(Rt/L) = 1/e = .368
i = 2.55 (1 - 0.368)
i = 2.55 * 0.632
i = 1.61 amps
energy = (1/2)(6.4)1.61^2
E = 8.29 Joules
Answer:
The weight of a 100 kg person on Earth is 100 N. This is because mass and weight are the same and do not change. On the Sun the person would weight 28 times more so you would multiply 100 N x 28 = 2, 800 N. The weight of a 100 kg person on Earth is 10.2 N.
Explanation:
but on the sun it would be zero because they would be burned to a chrip also
I'm Sorry but you forgot to put the statements
1. condensation
2. freezing
3. gas particles
4. moth balls
5. leave liquid
6. reacting
7. state of matter
8. sublimation
______________________________
1. temperature
2. increasing heat
3. its temperature begins rising from -20 C
4. it stops rising and stays steady at 0 C; the ice is using the
added heat to change state, melt, and turn to liquid
5. between 0 C and 100 C
6. it stops rising and stays steady at 100 C; it's being absorbed
by the water, and the water is using it to change state, evaporate,
and turn to gas
7. the heat is making the molecules move around easier
