Answer:
The metric system measures mass in grams or kilograms, distance in meters or kilometers, and volume in liters. It measures temperature in Kelvin or Celsius degrees instead of the Fahrenheit degrees used in the imperial system.
Unable to do so due to not knowing the terms or definitions.
Car is driven first 2.0 hour at the velocity 40 km/h.
We know,
Distance covered = Velocity * time.
Therefore, distance covered by car in first two hours = 40 * 2.0 = 80 km.
Car is driven second 2.0 hour at the velocity 60 km/h.
Therefore, distance covered by car in first two hours = 60 * 2.0 = 120 km.
Total distnace covered = 80 km + 120 km =200 km.
Total time taken = 2.0 + 2.0 = 4.0 hours.
Average velocity =
Plugging values in above formula, we get
= 50 km/h
Therefore, average velocity is 50 km/h.
Answer:
the action of polarizing or state of being or becoming polarized: such as the action or process of affecting radiation and especially light so that the vibrations of the wave assume a definite form. Polarization, in Physics, is defined as a phenomenon caused due to the wave nature of electromagnetic radiation. There are two types of waves, transverse waves, and longitudinal waves.
