Answer:
Q = 177J
Explanation:
Specific heat capacity of lead=0.13J/gc
Q=MCΔT
ΔT=T2-T1,where T1=22degrees Celsius and T2=37degree Celsius.
ΔT=37 - 22 = 15
Q = Change in energy
M = mass of substance
C= Specific heat capacity
Q = (91g) * (0.13J/gc) * (15c)= 177.45J
Approximately, Q = 177J
<span>Energy dissipated by friction is E
Initial Ei=mgh
Final Ef=1/2 mv^2
then subtracted Ef-Ei,
ΔE = 0
m g h -- E – 1/2 m v² = 0
66 (9.8) (250) - E - ½ (66)(14)² = 0
E = (9.8)(250) – ((14)^2)/2
E = 155.232kJ</span>
Answer:
The energy stored in a body due to either it's position or change in shape is called gravitational potential energy.
Just took the test. Its curved!
Hope this helps, if you wnna work together or need more help hmu/add me on discord @FaultyScript#3619
