Answer:
52.38 m/s
Explanation:
Answer:
54.23 m/s
Explanation:
-- time to fall from 140m = 5.35 s
-- vertical speed after 5.35 s =
Speed = (5.35) x (9.8) = 52.38 m/s
-- horizontal speed = (75m/5.35s)
Speed = 14.03 m/s
Resultant speed due to vertical & horizontal speed components:
Speed = sqrt(52.38^2 + 14.03^2)
Speed = 54.23 m/s

Answer:
<h3>Hydrogen gas is responsible for polarizination defect.</h3>
Answer:
5kgm
Explanation:
convert cm to m and g to kg
250/1000=0.25kg
5/1000=0.05m
then find the density
density=mass/volume
=0.25kg/0.05m
=5kgm
