Answer: 1350J
Explanation:
To solve this, we are going to use the formula for calculating potential difference which is:
Potential difference (V) = Work done (W) / Total charge (C)
Therefore,
9 volts = Work done / 150
Work done = 150 × 9 = 1350J
Answer:
We can use optical fibers.
Explanation:
The optical fibers are the optical devices which is based on the total internal reflection.
The optical fiber has two layers, one is called core and the other is called cladding.
The refractive index of core is more than the cladding.
As a ray of light falls on the core at more than the critical angle for that pair of media(core and cladding), it suffers the total internal reflection at the interface.
Anything that's moving in a straight line at a constant speed has zero acceleration, and that tells us that there is zero net force acting on it.
Explanation:
because the acceleration is negative, this indicates a deceleration (or slowing down) . Hence we can say that:
The car is decelerating (slowing down), i.e its velocity is decreasing, at a constant rate of 5m/s².
