Answer:
heeyya it is the second paragraph
Answer:
20.6 cm
Explanation:
charge per cm = 0.14 μC
number of electrons (e) =
to get the length of tape pulled we can apply the formula below
length of tape =
therefore we need to find the magnitude of the charge of the electrons
- 1 electron = C
now that we have the magnitude of the charge, we can find the length of the tape
- length of the tape = = 20.6 cm
The period of the planet is 58.1 years
Explanation:
We can solve this problem by using Kepler's third law, which states that:
"The square of the orbital period of a planet is proportional to the cube of its semimajor orbital axis"
Translated into equations, we can write:
Where, taking the orbits of the planets as almost circular, we have:
is the orbital period of the unknown planet
is the radius of the orbit of the planet
(1 year) is the period of the orbit of the Earth
is the orbital radius of the Earth
Solving for , we find the orbital period of the unknown planet:

Electric current is the flow of charge due to the potential difference between two terminals per unit time. It is denoted by I and its unit is amp. It can be mathematically expressed as I=Q/t.
If this isn’t what your looking for I need the options they gave you
It must be massive because momentum is the product of mass and velocity.
