Answer:
Vf = 9.622 m/s
Explanation:
Distance covered S=0.80m, Time t=0.087s and
g=9.81 m/s²
Required: Final velocity Vf when it hit the floor
Sol:
We have first find Vi so
Vi=Vit + 0.5 a t2
Vi =8.768m/s
Now Vf= Vi + at
Vf = 9.622 m/s
B. When the sun and the moon are aligned, their combined gravitational force attracts the water, causing super high tides on one side of the planet, and super low tides on the opposite side.
Answer:
first law: an object remains in uniform motion except an external force has acted upon it eg a ball in stable motion doesn't move until one moves or kicks it
second law:the body acted upon by an external force gains a momentum which is directly proportional to the applied force and acts in the direction of the force
third law: to every action there is an equal and opposite reaction eg if u push someone the person moves backward away from you and not towards you
True
Explanation:
when electrons stop.moving it cause a stoppage
in formation of magnetic field
i hope.it helps u
Speed = 500m/5min = 100 m/min. Direction = west. Velocity = 100 m/min west.
