I believe they should ask if a hydroelectric power plant emits lower CO2 than the thermal power plant. CO2 is one of the elements that causes global warming. Other choices such as asking for its costs or expensiveness and the number employees is not the major concern in global awareness.

24. A anvil with a mass of 60 kg falls from a height of 9.5 m. How fast is it going right
shepuryov [24]

So they give us this

V=IR

V= 1.8

I=0.4

R=?

So we insert the thing that we know.

1.8=0.4*R

We need to leave our unknown value alone. So if our value of 0.4 is multiplying the unknown value it passes to the other side dividing.

So we have this.

Lastly we solve.

R=4.5ohms

The formula to find R is V=IR

V/I=R

So the resistance will be the Voltage divided by the Current

The thrust from a car is 2000 N. The air resistance and friction together total 680 N. What happens to the speed of the car?
zheka24 [161]
The car will speed up because if the air resistance and friction forces are reacting in the direction opposite to the Applied force, The Net force will still be in the direction of the car's motion and since F=ma a will cause your velocity to increase

I really need help with this to be able to pass this last semester this is about (Circular Motion ) on physics

Question 1
To find centripetal acceleration, use the formula : centripetal acceleration = v^2/r
so answer would be (3.71)^2/42.85=0.32 (2d.p.)
Question 2
Force =ma
a= (9.98)^2/31.77=3.1350
Force= 3.1350 * 56.63 = 177.54 (2 d.p.)

sla’s change in velocity is 30 m/s, and Hazel has the same change in velocity. Which best explains why they would have different
sweet [91]
Because acceleration depends not only on the change in velocity.
It also depends on the time during which the change occurs.
The formula is

Acceleration = (change in velocity) divided by (time for the change) .

Maybe Sla changed his velocity in 3 seconds, but Hazel
took all morning to change hers.  In that case, even though
the amounts of change were equal, the times were different,
so the quotients of (change/time) were different.
