The force (attractive if the charges are dissimilar, else repulsive) is along a line that connects the two particles.
Explanation:
Heat liberated by a body depends on the mass of the body, the specific heat capacity of that body and the change in temperature experienced by the body.
Heat energy by a body depends on the surface area of the body A as well as the temperature of body T.
According to Stefan's law, rate of heat energy radiated by a body is given by P=σAeT^4
Thus more is the temperature of body, more is the heat radiated. Also mores is the surface area of body, more is the heat radiated.
Answer:
The support force/ Normal reaction force
Explanation:
Refer to Newtons third law.
"The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body"
Since we have a downward force acting on your object, in this case gravity/weight, there is an equal and opposite force given off by the surface the object is on. This is called the support force or the normal reaction force
Answer:
is in units of 
is in units of 
is in units of 
Explanation:
We have the following expression:
Where:
is the distance, hence its unit is (meters, assuming we are using the International System of Units)
is the time, hence its unit is 
(seconds)
So, the expression is rewritten as:
Since the left side of the equation is in meters, the right side must be in meters as well.
In addition, in the right side we have terms that have to added, this means each term must be in meters:
- For the first term must be in units of in order to have meters.
- For the second term must be in units of in order to have meters.
- For the third term must be in units of in order to have meters.
Answer:
a solar eclipse occurs when the moon passes in front of the sun,blocking it out partially or completely. the eclipse results in parts of the earth being covered in the shadow of the moon. a lunar eclipse occurs when the moon passes directly behind earth and into its shadow.
