According to the impulse--momentum equation Ft = change in mv, a bungee jumper in fall has momentum which is reduced by the forc
1 answer:
Answer:
The answer is a. Jumper
Explanation:
The change in the momentum is represented by the equation
Acceleration of any body is calculated by the product of the mass of the body and with the velocity the same mass is moving.
Since it is mentioned in the statement that m is the mass of the jumper then velocity will also be of the jumper to calculate the change in the momentum.
If the mass of bugle cord is taken, then its velocity will be taken for the equation.

The magnitudes of his q and ∆H for the copper trial would be lower than the aluminum trial.
The given parameters;
- <em>initial temperature of metals, = </em>
<em />
- <em>initial temperature of water, = </em>
<em> </em>
- <em>specific heat capacity of copper, </em>
<em> = 0.385 J/g.K</em>
- <em>specific heat capacity of aluminum, </em>
= 0.9 J/g.K
- <em>both metals have equal mass = m</em>
The quantity of heat transferred by each metal is calculated as follows;
Q = mcΔt
<em>For</em><em> copper metal</em><em>, the quantity of heat transferred is calculated as</em>;
<em>The </em><em>change</em><em> in </em><em>heat </em><em>energy for </em><em>copper metal</em>;
<em>For </em><em>aluminum metal</em><em>, the quantity of heat transferred is calculated as</em>;
<em>The </em><em>change</em><em> in </em><em>heat </em><em>energy for </em><em>aluminum metal </em><em>;</em>
Thus, we can conclude that the magnitudes of his q and ∆H for the copper trial would be lower than the aluminum trial.
