Answer:
[tex]\Huge \boxed{\mathrm{12.67 \ s}}[/tex]
Step-by-step explanation:
[tex]\displaystyle power \ (W) = \frac{work \ done \ (J)}{time \ (s)}[/tex]
[tex]\displaystyle P= \frac{W}{t}[/tex]
[tex]\displaystyle 15= \frac{190}{t}[/tex]
Solve for t.
Multiply both sides by t.
[tex]15t =190[/tex]
Divide both sides by 15.
[tex]\displaystyle t= \frac{190}{15}[/tex]
[tex]t \approx 12.67[/tex]
[tex] \bf \underline{ \underline{given : }}[/tex]
- Work = 190 J
- Power = 15 W
[tex]\bf \underline{ \underline{To \: be \: calculated : }}[/tex]
Calculate the time ?
[tex]\bf \underline{ \underline{
Formula \: applied :}}[/tex]
[tex] \boxed{ \bf{Power = \frac{Work \: done}{Time} }}[/tex]
[tex]\bf \underline{ \underline{Solution : }}[/tex]
We know,
[tex]\sf {Power = \dfrac{Work \: done}{Time}}[/tex]
[tex] \sf{ Time = \dfrac{Work \: done}{Power } }[/tex]
Substituting the values of work and power, we get:
[tex] \sf \implies{Time = \dfrac{190}{15} }[/tex]
[tex] \sf\implies{Time = 12.66 \: s}[/tex]
Thus,the time taken by a body is 12.66 seconds.
