Answer:
Metabolic power 420.138 W
Explanation:
Given data:
considering drag coefficient Cd = 0.9
Assuming cross section of cyclist A = 0.50 m^2
Take density of air ρ = 1.2 kg/m3
We know that drag force is given as
D = 14.388 N
hence metabolic power is given as
Metabolic power
= 420.138 W
Answer:
Explanation:
When a certain amount of substance is supplied with a certain amount of energy Q, the temperature of the substance increases according to the equation
where
m is the mass of the substance
C is the specific heat capacity
is the change in temperature
In this problem:
m = 150.0 g is the mass of wood
Q=67,000 J is the amount of energy supplied to the wood
is the increase in temperature of the substance
Therefore, the specific heat capacity is:
