Friction = 0.25 * m * g = 10.8
Push = m * a + Friction = 4.4 * 1.5 + 10.8
Weight Force of Junior = m g = 115kg x 9.81 m/s^2 = 1128.15N then
compute for the friction force
Friction Force= WF x (coefficient of kinetic friction) = 1128.15N x 0.35 = 394.8525N or 395N
But you can compute in a straightway:
Solution:
= 115 x 9.81 x 0.35
= 394.85
= 395 N
It will still give the same results.
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
We have to convert Gm/s to m/s.
As 
Therefore the speed of light in vacuum,

Thus, the speed of light in m/s is 
I think the correct answer would be A. If you are waiting to turn left into a small parking lot and a car is approaching from the opposite direction has a turn signal on, then you should wait until the other car starts its turn before making your turn. According to the general law on making a left turn, left turns should yield to the oncoming traffic. The vehicle that arrives in the intersection first would have the right of way to turn left. However, when there are two vehicles arrives at the intersection almost at the same time, then the one on the right would have the right of way.
