Answer
given,
mass of crate = 32.5 Kg
horizontal force = 14 N
initial speed, u = 0 m/s
a) acceleration produced = ?
we know,
F = m a


a = 0.431 m/s²
b) using equation of motion
t = 10 s


s = 21.54 m
c) again using equation of motion
v = u + at
v = 0 + 0.431 x 10
v = 4.31 m/s

Answer:

Explanation:
As per the formula of thermal expansion we know that

so here we will have



so here change in the length of the rod is given as




Internal and external combustion engines are two types of heat engines: they convert thermal energy into mechanical energy. The main difference between internal and external combustion engine is that in internal combustion engines, the working fluid burns inside the cylinder, whereas in external combustion engines, combustion takes place outside the cylinder and heat is then transferred to the working fluid.
