The examples may be;
making yogurt; If you heat beyond 130F you kill the cultures. The higher the temperature up until that point the faster it cultures until you close in on killer temperature.
Mixing 2 part epoxy; Keep it cool and the reaction time is delayed. On the other hand, heat it up and epoxy reacts quicker. In the winter time and close to 35 Degrees, the reaction time for cement to harden can take 400% more time to set.
Friction, engine thrust, normal reaction and weight, these are the forces acting on motor when it moves in a straight line
<u>Explanation</u>:
As per given question,
R is 0.895 m
The force between two objects is
Where,
F is the force of attraction between two objects in Newton’s (N)
R is the separation in meters (m) between the objects
Substitute the given values in the above formula,
Answer:
6000JOules
Explanation:
My friend this is quite easy.
There is an equation.
The energy is also presumed as heat.
To calculate the heat in a circuit or the energy the equation is H=I(square) RT
Heat= square of current x resistance x time
Here I=5a.
R=2 ohm
T=120s
H= 5x5x2x120=6000J
I hope this satisfies you.
