Answer:
The potential energy change is 0.596 J.
Explanation:
Given that,
Potential difference =14.9 V
Charge q =0.0400 C
We need to calculate the change potential energy
The potential energy change is the product of the charge and potential difference.
Using formula of change potential energy
Hence, The potential energy change is 0.596 J.
Electrons are a stable sub atomic particle that has a negative charge and is found in all atoms and is the main carrier of electricity through solids.
In a metal, some of the electrons can escape from the atoms and are free to move around inside the metal. These electrons are referred to as 'conduction electrons'.
<span>A current is a flow of charge. In metal a current is the flow of the conduction electrons through the metal. This can occur when connected to battery for example: The battery pumps the conduction electrons around the circuit. </span>
Answer:
Explanation:
Let's recall the acceleration definition.
(1)
Δv is the velocity variation, Δv = v(f) - v(i). It is just the difference between final and initial velocities. So Δv = 1.8[m/s] - 5.4[m/s] = -3.6 [m/s]
And Δt is the time variation, in this case it is just 1.5 s.
Therefore, using the equation (1), the acceleration will be:
The minus sign means that the tumbleweed is slowing down.

Hey there!
You cannot cut through steel with a plastic knife. As fun as it sounds, it is <u>not </u>a good idea to try, and 99.9% of the time it would not work.
Hope this helps!
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
