Mv + mv = 2mv providing each momentum is in the same direction.
1/2 mv^2 + 1/2 mv^2 = mv^2
No. The correct one would be D .
Answer:
Watt
Explanation:
Power is measured in Watts. J/s is the base unit of measurement, but we usually measure power in Watts (W).
In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive where and when events occur differently.
