Answer:
90
Explanation:
take note that V=
(velocity is distance over (divided by) time. so in this case its 198(distance) divided by 2.2 (time) =90
Answer:
yea that is very true ◠﹏◠✿
Explanation:
Answer:
The distance is
Explanation:
From the question we are told that
The smallest shift is ![d = 0.2 \ grid \ units](https://tex.z-dn.net/?f=d%20%3D%200.2%20%5C%20grid%20%5C%20units)
Generally a grid unit is
of an arcsec
This implies that 0.2 grid unit is ![k = \frac{0.2}{10} = 0.02 \ arc sec](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B0.2%7D%7B10%7D%20%3D%200.02%20%20%5C%20%20arc%20sec)
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
![d = \frac{1}{k}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Cfrac%7B1%7D%7Bk%7D)
substituting values
![d = \frac{1}{0.02}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Cfrac%7B1%7D%7B0.02%7D)
![d = 50 \ parsec](https://tex.z-dn.net/?f=d%20%3D%2050%20%5C%20parsec)
Note ![1 \ parsec \ \to 3.26 \ light \ year \ \to 3.086*10^{13} \ km](https://tex.z-dn.net/?f=1%20%5C%20parsec%20%20%5C%20%5Cto%203.26%20%5C%20light%20%5C%20year%20%5C%20%5Cto%203.086%2A10%5E%7B13%7D%20%5C%20km)
So
It is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
<h3>What is Gravitational interaction?</h3>
This is defined as the interaction between a particle or body resulting from their mass. This type of interaction is usually weak and occurs in all distances possible.
It is not gravitational interaction, because the rod attracts paper only against the gravitational force of the earth and there is no attraction between both bodies under a different condition.
This is therefore the reason why it is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.

Answer: Work that the motor of the crane do is 61122 joules.
Explanation:
Work is defined as the force resulting into displacement of an object.
w = work done
m= mass of object = 334 kg
g = acceleration due to gravity =
h = height of an object = 18.3 m
Putting in the values:
Thus work that the motor of the crane do is 61122 joules
