For the first one, its B) cities B and C
I'm not so sure, but I hope this helps.
Answer:
A) Become 1/ 2 of its original value.
B) Become one-half of its original value.
Explanation:
As we know that heat transfer trough the wall of thickness t given as
Where
K=Thermal conductivity of the wall
A= Cross sectional area of the wall
t=Thickness of the wall
ΔT=temperature difference across the wall surfaces.
When the thickness become double ,lets sat t' = 2 t
Then new heat transfer
Therefore the new heat transfer become half of the original.
Physiotherapy is the treatment to restore, maintain, and make the most of a patient's mobility, function, and well-being. Physiotherapy helps through physical rehabilitation, injury prevention, and health and fitness.
If ball 1 has a higher speed than ball 2, then ball 1 has higher kinetic energy than ball 2, since kinetic energy is the energy of movement.
Explanation:
The box has no acceleration in the perpendicular direction, so the net force in that direction is 0.
Sum of forces in the parallel direction:
∑F = f − F∥ − mg∥
∑F = f − F cos φ − mg sin θ
