ANSWER:
What is the difference between heat and light? - Physics Stack ... Heat and light are different but they are both forms of energy. Heat is a form of kinetic energy contained in the random motion of the particles of a material. Light is a form of electromagnetic energy. As with other forms of energy, heat energy can be transformed into light energy and vice versa.
Answer:
c) equals V
Explanation:
This is because, since the isolated, irregularly shaped piece of platinum is in electric equilibrium, the electric potential at all points on its surface is V. So that, the potential difference across any point is zero. This implies that diametrically opposite sides have the same potential and thus, the potential at other points of the surface is V since it is in electric equilibrium.
Explanation:
It is given that,
Initially the car is at rest and travels for t₁ seconds with a uniform acceleration a₁. The driver then applies the brakes, causing a uniform acceleration a₂, If the brakes are applied for t₂ seconds.
We need to find the speed of the car just before the beginning of the braking period.
Using the formula of acceleration. It is given by :
u = 0
So, just before the beginning of the braking period the speed of the car is . Hence, this is the required solution.
First you need to know to gain or lose speed you must have acceleration of deacceleration in the direction of speed !!
so at highest point , the only acceleration is gravity and that is in the downward direction so , the velocity remains constant !!
False, it depends on where the source is, and where all observers are located. If some are further than other, then they will feel less of the frequency then those closer, and will not be as affected
hope this helps
