Average speed is the ratio of total distance moved by Chi in total time interval
So here we will have
Total distance = 100 m + 400 m
Total time taken = 5 min + 15 min = 20 min
now by the formula of average speed we know that
so average speed will be 1.5 km/h
B) The amount of work done
Answer:
the total mass is 35 kg
k.E = 1/2 mv2
43.76 =1/2 v2
v2=2×43.76
Explanation:
v=radicls 87.52 which is equal to 9.5 m/s
Answer:
Explanation:
The magnetic field strenght on the z-axis at a distance d from the center is,
Our values are:
Replacing,
Answer: Galileo's laws of Motion determined that the natural state of an object is rest or uniform motion, objects always have a velocity, sometimes that velocity has a magnitude of zero rest. objects resist change in motion, which is called inertia.
