Answer:
Explanation:
We would most likely write the velocity of the ball as follow :
V(b<em>all</em> with respect to t<em>rain)</em> = Vbt
Answer:
50N
Explanation:
Force (N) = mass (kg) × acceleration (m/s²)
0.25kg times 200m/s² = 50N
Answer:
The energy of the photon from the higher-wattage bulb is equal to the energy of the photon from the lower-wattage bulb.
Explanation:
Answer:
To see objects smaller than microscopic limits
Explanation:
The theory of Relativistic Quantum mechanics can be applied to particles that are massive and propagates at all velocities even those which are comparable to the speed of light and is capable to accommodate particles that are mass less. This theory find its application in atomic physics, high energy physics, etc.
It is necessary to use relativistic quantum mechanics when it is desired to see the objects that are too small to be seen with the help of microscope.
Power is energy per unit time. If he is powerful, it means he can spend more energy in short span of time, so option C ( i.e. <span>do more work in less time) is correct.</span>
