It is a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects
Answer: 750 N
Explanation:
The net force is 1200 - 450 = 750 N
As we are told the speed is constant, then this force must be increasing the car's potential energy by climbing a hill.
F = mgsinθ
If we knew the car mass, we could find the hill slope angle.
If we knew the hill slope angle, we could find the car mass.
Answer:
The pressure will be of 399.17 mmHg.
Explanation:
p1= 754 mmHg
V1= 4.5 L
p2= ?
V2= 8.5 L
p1*V1 = p2*V2
p2= (p1*V1)/V2
p2= 399.17 mmHg
Because of how it's worded the answer would most likely be number four
