Answer:
382.74 kJ.
Explanation:
The work that must be done to stop an 1100 kg car travelling at 59 km/h is - 382.74 kJ.
Explanation:
The given data is as follows.
distance (r) = 1.67 m
= 1 C
It is known that formula for electric force between two charges is as follows.
F = 
Hence, putting the given values into the above formula as follows.

= 
As it is given that mass of Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.
weight of 1 falcon rocket =
Therefore, number of falcon rockets will be calculated as follows.
No. of falcon rockets = 
=
= 2318.9 falcons
Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.
Based on the values of E, C, and R, the maximum charge on the capacitor can be found to be 1.80 x 10⁻⁴ C.
<h3>What is the maximum charge?</h3>
The maximum charge on the capacitor can be found as:
= C x ( 10⁻⁶ / 1 μF) x E
Solving gives:
= 20.0 x ( 10⁻⁶ / 1 μF) x 9.00
= 1.80 x 10⁻⁴ C
In conclusion, the maximum charge is 1.80 x 10⁻⁴ C

Answer:
Galileo Galilei
Explanation:
although Galileo was not the scientist who invented the telescope, he was the first to use it to observe celestial objects. he used the telescope in 1609. his discovery included more accurate information about the moon, the sun and some of the planets.
One scientist believe that the ozone layers of the earth had been weakening and waters current changes directly over 5 to 7 months. hope that helped
