v2 = v1 + at
60 = v1 + 4*10 v1 = 20 m/s
Answer:
Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy.
I believe it's conduction
Answer:
The answer is most likely C.
Ready-to-eat foods are stored at the top of the fridge, away from raw foods so that harmful bacteria cannot transfer from the raw food to the cooked food. Raw meat, poultry and fish in sealed containers to stop them touching or dripping onto other foods.
Answer:
Workdone =0
Explanation:
The body is inclined at θ=30°, s=10m, m=5kg
Workdone by the object = FsCosθ
but the surface is a friction-less surface, this means coefficient of friction =0
F=μR
F=0*R
F=0
W=FScosθ
W=0*SCosθ
W=0
