One can simply find the frictional force acting on an object using this equation:
(Ffrict<span> = μ•F</span>norm<span>)
</span>
The process of determining the value of the individual forces acting upon an object involve an application of Newton's second law (Fnet=m•a) and an application of the meaning of the net force. If mass (m) and acceleration (a) are known, then the net force (Fnet) can be determined by use of the equation.
<span>Fnet = m • a</span>
If the numerical value for the net force and the direction of the net force is known, then the value of all individual forces can be determined.
Answer:
Melting point
Explanation:
when a solid turns to a liquid, it is melting
Answer:
The answer to your question below
Explanation:
Processes from solid to liquid or from liquid to gas absorb energy.
Processes from gas to liquid or liquid to solid release energy.
Condensation phase change that releases heat
Freezing phase change that releases heat
Melting phase change that absorbs heat
Sublimation phase change that absorbs heat
Vaporization phase change that absorbs heat
Answer:
As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. ... Thus, entropy measurement is a way of distinguishing the past from the future.
Explanation:
The magnitude of the force exerted by the fish is 3,052.5 N.
The given parameters;
- mass of the reel, m = 652 g = 0.652 kg
- diameter of the reel, d = 10 cm
- radius of the reel, r= 5 cm = 0.05 m
- angular speed of the reel, ω = 306 rad/s
According to Newton's third law, the force exerted by the reel is equal in magnitude to the force fish exerted on the reel.
The centripetal force of the reel = force exerted by the fish
Thus, the magnitude of the force exerted by the fish is 3,052.5 N.
