Answer:
Check the correctness of the relation c=1 √μ0∈0 where the symbols have their usual meaning. check-circle.
Answer:
Scalar quantity is the Physical quantity expresed only by their magnitude.
Distance (s) =20 m
Initial velocity =0 m/s
g=10 m/s²
By using the formula:
v²= u²+ 2as
v²=0²+ 2×10×15
v²= 300
V= 10root over 3

For calculating time,
v= u+ at
10 root over 3 = 0+ 10t
10 root over= 10t
t = 1 root over 3
t = 1.73 s

The the stone will hit the ground with a velocity of 10 root over 3 m/s in 1 root over 3 sec.
