Explanation:
12N by first law of newton is net force after colloision
The water temperature rises from 25*C to 28.4*C, thats 3.4*C so the heat absorbed is
<span>mass x change in temp x shc </span>
<span>= 0.150 x 3.4 x 4186 </span>
<span>=2134.86J </span>
<span>Now the bolt release the same energy </span>
<span>So mass x change in temp x shc = 2134.86J </span>
<span>0.085 x (85-28.4) x shc </span>
<span>So </span>
<span>shc = 2134.86 / (0.085 * 56.6) </span>
<span>= 443 J/KgC</span>
Answer:
306J
Explanation:
The formula for kinetic energy is given as ½mv².
Using this, we get our answer by substituting the values into the formula.
½ × 0.145kg × 65m/s
= 306.31J
can be rounded off to 306J
It will stay in motion unless an outside force slows it down.
