Answer:
so you have a question
Explanation:
either way have a nice day
Answer:
0.0804 m / h
Explanation:
r = 1 m, dr / dt = 8 cm/h = 0.08 m/h
the volume of sphere is given by
V = 4/3 x π x r^3
Differentiate with respect to r.
dV / dr = 4 / 3 x π x 3 r^2 x dr/dt
dV/dt = 4 x π x r^2 x dr/dt
dV/dt = 4 x 3.14 x 1 x 1 x 0.08
dv/dt = 0.0804 m / h

Hope I helped (:
Have a great day!
Answer:
Explanation:
Net work done on the box = increase in kinetic energy
= 1 / 2 x 10 ( 5² - 3² )
= 80 J .
Answer:
1.1655 N
Explanation:
Given that,
Initial speed, u = 25 m/s
Final speed, v = 26 m/s
Time taken, t = 54 s
So, Applying equation of motion as:

According to the Newton's second law of motion:-

Mass = 63 kg
So,

<u>Force = 1.1655 N</u>
