The amount of heat lost by the water is 1870 calories
Step-by-step explanation:
The amount of heat released by a substance is given by the equation
where
Q is the amount of heat lost
m is the mass of the substance
C is the specific heat capacity of the substance
is its change in temperature
In this problem, we have:
m = 85 g is the mass of water
is the specific heat capacity of water
is the change in temperature of the water
Substituting, we find

Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
We have to simplify this using the properties of exponents.
The property that we use here is:
So, let us simplify the powers of separately and -24 and 8. This gives,
Therefore, the simplified form is:
Answer:
According to Pythagoras Theorem- a²+b²=h²
So, a²+13²=29²
=>a²+169=841
=>a²= 841-169= 692
=> square root of 692= 26.3
