The heat of the heating element stops when the desired temperature in an electric iron is reached because A. the thermostat blade opens electrical contacts.
This is why heating ceases to rise or fall (it stops completely) once the thermostat's blade opens.
Answer:
19.53 cm
Explanation:
The computation of the height is as follows:
Here we applied the conservation of the energy formula
As we know that
P.E of the block = P.E of the spring
m g h = ( 1 ÷ 2) k x^2
where
m = 0.15
g = 9.81
k = 420
x = 0.037
So now put the values to the above formula
(0.15) (9.81) (h) = 1 ÷2 × 420 × (0.037)^2
1.4715 (h) = 0.28749
h = 0.19537 m
= 19.53 cm
Answer:
Chimps and apes are still here because humans did not evolve from all apes and chimps.
