Answer:
The force will increase in proportion to the mass of the objects
Explanation:
The acceleration due to gravity is always the same. It is expressed in meters per second squared or m/s². The figure of 9.81 m/s² is an average value that was taken after calculating the acceleration under different surfaces. In fact, the acceleration differs depending on the shape of the part of the earth in relation to the earth's magnetic field and force.
Thus, if one washer was 20 kg, the acceleration being 9.81 m/s² the weight will be:
F = ma
= 
If there are there washers, the weight will be:
F = 3 * 20 * 9.81
= 588.6 N
The heat flows into the sample in the segment <u> BC </u> will yield the value of the heat of fusion of this substance.
<h3>Heat of fusion:</h3>
The heat of the fusion of water is unusually high. The amount of heat required to convert 1 g of solid into a liquid while maintaining the same temperature is known as the heat of fusion. It is a latent heat as well and is occasionally referred to as the latent heat of fusion. Since water only freezes at a single temperature (0 °C), it only has one value, which is 79.71 cal/g, or the rounded amount of 80 cal/g.
In order to control frost, water fuses at a high temperature. The water used for irrigation is frequently consistently above freezing when it is extracted from the ground.

All planets orbit the sun in a plane, all the planets orbit the sun in the same direction, most of the planets rotate in the same direction. I'm not sure when and answer ends or begins on your question so you can choose from some of the answers I gave you.
Answer:
Explanation:
For this case we assume that we want to find the electrical field at the point P as we can see on the figure attached.
The electrical field wormula is given by:
Where r is the distance from the point and the charge. On this case we can use the Pythagoras theorem and we got:
And now we can replace into the formula since we know that 
and 
, and we got:
B) All natural radiation is at a level low enough to be safe.
