1.igneous rocks are formed when magma or lava cools and hardens
2. the cooling rate of the rock
Answer:
True
Explanation:
Newtons Law states that "When a net force acts on a body, it produces acceleration in the body in the direction of the net force. The magnitude of acceleration is directly proportional to the net force and inversely proportional to its mass."
So, it's mathematical form is
=> a ∝ F (1)
=> a ∝
Combining the proportionality
=> a ∝
=> F ∝ ma
Using k as proportionality constant.
=> F = kma
Here k = 1
=> F = ma (Proved)
The amount of charge on each plate is equal to 0.9 Coulombs.
<u>Given the following data:</u>
To calculate the amount of charge on each plate:
<h3>The formula for work done.</h3>
Mathematically, work done in moving a charge is given by this formula:
<u>Note:</u> The work done by an external force equals the change in potential energy for the charges that were moved.
But,
Now, the work done becomes:
Making q the subject of formula, we have:
Charge, q = 0.9 Coulombs.
