Water at normal temperature is a good lubricant and will hinder the brake from working properly when the road is wet. To dry the brakes off, apply brakes gently as you accelerate. This will generate some heat that will evaporate the water with the help of friction.
Answer: LET'S TAKE GRAVITY ON EARTH AS 10 N/KG AND ON MOON AS 0.6 N/KG
a) weight=15kgx10N/kg
= 150N
b) weight=15x0.6=9N
c) mass=is the same so 15kg
d) mass is measured in kg, weight in NEWTONS OR 
e) when the gravitational force is zero
Explanation:
Good question because although this earth going through hell the earth will never break because its solid
Tbh I don’t know how earth is still put together after so much effect
Power is the rate of work done or produced by a system. It will have units of Watts which is equivalent to Joules per second. To determine the work or energy produced by the system, we multiply power with time. We do as follows:
Energy = Power x time
Energy = 1500 J/s (2.0 hr) (3600 s / 1 hr)
Energy = 10800000 J
