Answer:300 joules
Explanation:The formula for specific heat is:
E
=
m
c
θ
, where:
E
is the energy needed in joules,
m
is the mass in kilograms,
c
is the specific heat,
θ
is the change in temperature, Celsius of Kelvin doesn't matter.
Here,
m
=
0.125

Answer:
65.3 Inches tall
Explanation:
If Sammy is 5 feet and 5.3 inches tall, we simply need to convert the feet to inches, and sum the remaining inches from his height to determine his overall height in inches.
So, 5 feet = (12 inches/1foot) * (5 feet) = 60 inches
And 60 inches + 5.3 inches = 65.3 inches.
Hence, Sammy is 65.3 inches tall.
Cheers.
