Answer:

The answer is Negative charges repel other negative charges and attract positive charges.

Explanation:

Taking into account the law of charges, which expresses that charges of the same sign tend to repel, while charges of different signs attract; that is to say that the electrostatic force between charges of the same sign is repulsive, while said force on charges of different signs is of attraction. Therefore, it is understood that negative charges repel other negative charges and attract positive charges.

An object with a mass of 20 kg has a net force of 80 N acting on it. What is the acceleration of the object?
Archy [21]

Answer:

4m/s^2

Explanation:

mass(m)=20 kg

force=80 N

acceleration (a)=?

Therefore,

Force = mass * acceleration

80 = 20*a

a=80/20

=4m/s^2

Which prediction of weather is the most accurate for the next two days if there is an occluded front over the area?
alisha [4.7K]

The most accurate weather for the next two days would be dry warm weather or severe thunderstorms if there is an occluded front over the area.

<u>Explanation:</u>

The weather front that is created during the cyclogenesis process is an occluded front in meteorology. Cyclogenesis process is the development of extra-tropical cyclone and its intensification.

During the occurrence of this, the warm air is occluded (separated) from the center of cyclone at the surface of the earth.

The cold front rotates the storm as it intensifies and holds up the warm front. This develops an occluded front, that is the boundary which separates the new cold air mass and the older cool air mass that is already in warm front's north.
