Answer:
Venus observation.
Explanation:
Galileo had learned regarding the heliocentric (Sun-centered) idea of Copernicus, and acknowledged it. However, the theory was proven by Galileo's observations of Venus. Galileo concluded that Venus should travel round the Sun, sometimes passing behind and then beyond, instead of directly rotating around the Earth.
Answer:
Helium will have the highest average speed
Explanation:
the kinetic molecular theory tells us that the temperature of a gas is directly proportional to the average kinetic energy of the gas. So since all three gases have the same temperature, they must have the same kinetic energy. Kinetic energy is KE = 0.5mv². How then can a gas with such a small molar mass like helium have the same kinetic energy as much heavier gases like oxygen and sulphur dioxide? By having a much larger average speed
Answer:
Speed is a scalar quantity it is the rate of change in the distance travelled by an object, while velocity is a vector quantity it is the speed of an object in a particular direction.
Answer:
Answer is 25 kg m/s.
Explanation:
Given Data ;
mass = 0.5 kg
velocity = 10 m/s
Find ;
K.E = ?
Formula ;
KE = 1/2 mv 2
Solution:
KE = 1/2(0.5)(10)²(kg)(m/s)
=25 kg m/s
