Answer: It's A
conduct smaller studies for more than a one-year period
Answer:
0.031 m
Explanation:
Density of copper = ρ = 8960 kg/m³
r = Radius = 0.262 m
m = Mass of plate = 61.5 kg
v = Volume of plate = Volume of cylinder = πr²h

So, thickness of plate is 0.031 m

Although water makes up a large portion of our earth, only a tiny fraction is drinkable. That is why we must protect it because if it becomes to dirty to purify, it could lead to not enough drinking water for us
The average power is 20.3 kW
Explanation:
First of all, we calculate the work done on the car: the work-energy theorem states that the work done on the car is equal to the change in kinetic energy of the car, so we have

where
W is the work done
are the initial and final kinetic energy of the car
is the mass of the car
u = 0 is the initial velocity
v = 18.0 m/s is the final velocity
Substituting,

Now we can find the average power developed by the car's engine, which is given by

where
is the work done
t = 12.0 s is the time taken
Substituting,
