If you were to rase to temperature 10c and the heat energy required to rase it 1 c is 4190 j/(kg C). 24g • 4190 j/(kg C) • (35-25)C 24 • 4190 • 10= 1,005,600 j or 1.5 MJ
Define displacement and I'll help you
Answer:
835/(320*9.8)=0.266
Explanation:
since the safe is moving at a constant speed then the net force is zero
in other words the friction force equals the sum of Bonnie and Clyde force
so the friction force must be 485+350=835N
the frictional force = mu*m*g
Answer:
β = 16.7°
Explanation:
The sum of forces on the x-axis are:
The sum of forces on the y-axis are:
By dividing x-axis by the y-axis equation:
Solving for β:
β = 16.7°
