frosja888 [35]

Answer:

2,7 m

Explanation:

You can solve this doing an energy balance:

$m*g*h-\frac{1}{2} *m*v^{2} =41,7[J]$

Solving this equation to get h:

$\frac{41,7- \frac{1}{2} *m*v^{2} }{m*g}=h$

Replacing the values and solving brings to 2,7 m

The specific silver is How many joules of energy are needed to warm 4.37 g of silver from 25.0 degrees * C to 27.5 degrees * C ?

Alexxandr [17]

0.24J/g*degC * 4.37g * 2.5degC = 2.622J

The 2.5 degC is the difference between 25 and 27.5 deg C.
