The calculation of kinetic energy uses the formula, ke = 1 2 mv2. identify the unit that is required for mass and velocity, respectively, to determine the kinetic energy in joules. a) mass in g, velocity in m s b) mass in kg, velocity in m s c) mass in g, velocity in km hr d) mass in kg, velocity in km hr

So the answer  is B.  because the mass have  Kg as a international unit and velocity is m/s, they are  international units in physics.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
