Answer : The specific heat of aluminum is, 
Solution : Given,
Heat absorbs = 677 J
Mass of the substance = 10 g
Final temperature = 
Initial temperature = 
Formula used :
or,
Q = heat absorbs
m = mass of the substance
c = heat capacity of aluminium
= final temperature
= initial temperature
Now put all the given values in the above formula, we get the specific heat of aluminium.
Therefore, the specific heat of aluminum is,
Heat exhaustion is usually accompanied by a fever no higher than 104 degrees Fahrenheit, excessive thirst, nausea, fainting, cool and clammy skin, weakness, muscle aches, heavy sweating, slow heartbeat and dizziness. Heatstroke may develop following heat exhaustion if the condition is not treated.
It has been stored in fuels such as coal and oil, formed from the fossilized remains of plants or animals over millions of years.
The period of the pendulum doesn't determine the length of the string.
It's the other way around.
The period of the pendulum is proportional to the square root of its length.
So if you want to triple the period, you have to make the string nine times
as long as it is now.
