Answer:2 amperes
Explanation:
Voltage=120v
Total resistance=15+15+30
Total resistance=60 ohms
Current=voltage ➗ resistance
Current=120 ➗ 60
Current=2 amperes
Average velocity is different than average speed because calculating average velocity involves considering the direction the bodies are moving.
When calculating average speeds you don't have to consider directions of the bodies.
This is because velocity is a vector quantity which must be defined by direction. Speed is a scalar quantity thus it does not have to be defined by direction.
Answer:
Explanation:
30 N force is pulling total mass of 15 kg , so acceleration in the system of masses
= 30 / 15
= 2 m / s²
Let us now consider forces acting on 9 kg . 30 N is pulling it in forward direction . Tension T in the string attached to it is pulling it in reverse direction
so net force on it
30 - T
Applying Newton's law of motion on it
30 - T = mass x acceleration
30 - T = 9 x 2
30 - 18 = T
T = 12 N
The acceleration. The units of acceleration in this case are
When we multiply that by time (8 seconds, or 0.0022hrs in this case) our units are then miles per hour.
<span>It is true because the near side of the moon is attracted by the gravitational force due to the alignment of the planet in one Straight line.The opposite side is due to the movement of earth towards moon side during alignment.Soon both side, there will be high tide at the same time.</span>
