Therefore, the ball has a velocity of 4m/s.
I believe it's Seismographs, Tiltmeters, and Correlation Spectometers.
Hopefully I helped ^~^
Answer:21.45 m/s
Explanation:
Given
Mass of sport car=920 kg
Mass of SUV=2300 kg
distance to which both car skid is 2.4 m
coefficient of friction (
)=0.8
Let u be the initial velocity of both car at the starting of skidding
and they finally come to zero velocity


s=2.4 m

u=6.13 m/s
so before colliding sport car must be travelling at a speed of
(conserving momentum)
v=21.45 m/s
Answer:
0.5 V
Explanation:
The electric potential distance between different locations in an electric field area is unaffected by the charge that is transferred between them. It is solely dependent on the distance. Thus, for two electrons pushed together at the same distance into the same field, the electric potential will remain at 1 V. However, the electric potential of one of the two electrons will be half the value of the electric potential for the two electrons.
Answer:F=648 N
Explanation:
Given
mass of man 
mass of Platform 
acceleration of system 
Let F be the force with which man pulls the rope which will also create a tension of F in rope
