Answer:
density ρ = mass / volume
ρ = 100 g / 11.2 cm^3 = 8.93 g/cm^3
Probably copper because a value given for Cu is 8.89 g/cm^3
Answer:
the state of giving off light or glow.
Explanation:
- Speed is the rate of change of distance with time.
Speed =
- Velocity is given as the displacement per unit of time:
Velocity =
Speed and velocity are similar but speed is a scalar quantity while velocity is a vector quantity. Speed has magnitude but does not point towards a specific direction. Velocity shows both magnitude and direction and it is a vector quantity.
- Acceleration is given as the change in velocity with time. It is a vector quantity:
Acceleration =
- Distance is how far a body moves. It is scalar quantity.
- Time is the duration of an event. It is a scalar quantity.
