Answer:
the heat absorbed by the block of copper is 74368.476J
Explanation:
Hello!
To solve this problem use the first law of thermodynamics that states that the heat applied to a system is the difference between the initial and final energy considering that the mass and the specific heat do not change so we can infer the following equation
Q=mCp(T2-T1)
Where
Q=heat
m=mass=2.3kg
Cp=0.092 kcal/(kg C)=384.93J/kgK
T2=Final temperatura= 90C
T1= initial temperature=6 C
solving

the heat absorbed by the block of copper is 74368.476J
A.gold is the answer. As it's density is 19.32 grams per cubic centimeter which is lot more than the other substances.
Answer:
50N
Explanation:
Given parameters:
Mass of the bike = 10kg
Acceleration = 5m/s²
Unknown:
Force on the bike = ?
Solution:
To solve this problem, we apply Newton's second law of motion.
Force = mass x acceleration
Force = 10 x 5 = 50N
