The Awnser is C because in the chart it shows the temperature increases
Because a lot of people live along the fault line and there would be lots of death and much property damage.
Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
- Velocity is a vector quantity, which consists of a magnitude (the speed) and a direction. In the case of the circular motion, as in this problem, the speed is constant (45 m/h), but the direction is constantly changing, so the velocity is changing as well.
- Acceleration is also a vector quantity, whose magnitude is equal to the rate of change of the velocity, and the direction is given by the change in direction of the velocity. Therefore, since the velocity is changing, the acceleration in this problem is changing as well.
To find the magnitude of the boy's applied force, use newton's second law (where the force is the mass times the acceleration)
F = ?
m = 24 kg
a = 0.50 m/s^2
F = ma
F = (24 kg) (0.50 m/s^2)
F = 12 N
therefore the magnitude of the boy's pushing force is 12 N
I think nitrogen as it is the major component
