The spring constant, k will be 18 N/m.The ratio of force to one unit of displaced length is known as the spring constant.
<h3>What is the spring constant?</h3>
Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant,K=?
The formula for the spring constant when the spring is oscillate at the given amplitude A:
Hence, the spring constant, k will be 18 N/m

Answer:
C i think sorry if inmccorect
Explanation:
Answer:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Explanation:
The total distance covered by the person is 12 times the height of each stair:
The work done by the person to climb the stairs is equal to the increase in his gravitational potential energy:
And therefore, the power generated by the person in 12 s is the work done divided by the time taken:
So, the correct answer is B.
added to the engine minus the waste heat
Explanation:
The amount of work done by a heat engine equals the amount of thermal energy added to the engine minus the waste heat.
Thermodynamics is used to measure the energy changes that accompanies physical and chemical process.
In a system;
Internal energy = Quantity of heat added - Work done on it
internal energy is designated as ΔU
quantity of heat as Q
work done as W
ΔU = Q - W
so W = Q - ΔU
some of the heat added added to the system goes as waste heat as no system is 100% efficient.
the work done on a system goes in as thermal energy, internal energy and waste heat
