A total of 54.0 Joules of heat are absorbed as 58.3 g of lead is heated from 12.0° C to 42.0° C. What is the specific heat of le

DedPeter [7]

to increase the temperature of lead we know that the formula of heat required is given as

$Q = ms\Delta T$

here we know that

$Q = 54 J$

m = 58.3 g

$\Delta T = T_f - T_i$

$\Delta T = 42 - 12 = 30 ^0C$

now from the above equation we have

$54 = 0.0583*s *30$

$54 = 1.75*s$

$s = 31 J/kg ^0C$

also we can write its as

$s = 0.031 J/g ^0C$

Bob (88 kg) jumps out of a plane, starting at rest. After falling for 1 km, he is moving downward at 96 m/s. How much work is do

Vlad1618 [11]

Answer:

The work done by friction is 456 kJ.

Explanation:

Given that,

Mass of Bob, m = 88 kg

After falling for 1 km, he is moving downward at 96 m/s. It is required to find the work done by friction over this distance. It can be calculated using work energy theorem as :

$mgh+W=\dfrac{1}{2}mv^2\\\\W=\dfrac{1}{2}mv^2-mgh\\\\W=m(\dfrac{1}{2}v^2-gh)\\\\W=88\times (\dfrac{1}{2}\times (96)^2-9.8\times 1000)\\\\W=-456896\ J\\\\W=-456\ kJ$

So, the work done by friction is 456 kJ. Hence, this is the required solution.
