Final velocity = 5km/sec = 5000 m/sec
Initial velocity = 0, mass = 5kg and force = 500,000 N
F = m(Vf-Vi)/time
Time = m(Vf-Vi)/force = 5*5000/500000 = 0.05 seconds
So, it takes 0.05 sec to arrive at the speed of 5km/s.
Answer:
= 1.7 Joules
Explanation:
The electrical potential energy is given by;
P.E = 1/2 ke²
Where, k is the spring constant, e is the extension
Therefore;
Electrical potential energy = 1/2 × 113 N/m × 0.03 m
= 1.695 Joules
<u>= 1.7 J</u>
Pls don't mind my writing. hope this helps you tho
The water formed on the surface of the water evaporation loss (evaporation), consisting of plant transpiration water loss (transpiration) is called. Soil near the plant and the resulting water loss is called by evapotranspiration.
