Answer:
20.18 J
Explanation:
We are given that
Mass of bx=m=1.1 kg
Height=h=1.75 m
Initial speed of box=u=2.99 m/s
Final speed,v=2.56 m/s
We have to find the mechanical energy lost due to friction.
Energy at top=
J
Where 
At bottom,h'=0
Energy at bottom=
Energy lost=Energy(Top)-Energy(bottom)=23.78-3.6=20.18 J
Answer:
True
Explanation:
A different type of habitat exists in the caves. There exist no green plants/producers but still various life forms evolve with in the caves. The major source of nutrients with in the caves is water and intrusion of other organism that led to deposition of food in the form of debris/guano etc. These food deposits are intake by the organisms living in caves leading to start of food cycle. This is very much similar to any other food cycle
The electrical power or rate at which internal energy is produced in the copper wires is 435.6 W.
<h3>What is the internal rate at which internal energy is produced in the copper wires?</h3>
The internal energy produced in the copper wires is energy due to the resistance in the wire and is converted to heat energy.
The rate at which it is produced is electrical power.
Therefore, the rate at which internal energy produced in the copper wires is given as follows:
Power = I²R
R = l * 0.108 Ω/300m
Power = 110² * (2 * 50 * 0.108 Ω/300m)
Power = 435.6 W
In conclusion, electrical power is lost as heat in the wires.

This is another time to look at Newton's 2nd law of motion:
Net Force = (mass) x (acceleration)
If the object is not moving, then its acceleration is certainly zero, and Newton's law looks like this:
Net Force = (mass) x (zero)
or Net Force = (zero) .
"Net Force = zero" means that if there ARE any forces acting on the object, then they add up to zero, and we call them "balanced" forces.
So the answer is '<em>yes</em>', and that's why.
