As we know that time period of simple pendulum is given as
T = 2π √L/g
Answer:
Varies from point to point on the surface of the material.
Explanation:
Diffusion reflection is the reflection of light due to irregular reflection angles on the material surface. It might be as a result of microscopic irregularities on the material surface or just plain non reflecting ability of the material.
Heat absorbed is given by multiplying the specific heat capacity with the mass of the substance and the change in temperature.
specific heat capacity of iron= 460.5 J/kg/k
therefore, heat = mcФ, where c is heat capacity, m is the mass of iron and Ф is change in temperature. Change in temperature is 14 (20-6), mass in kg (0.057 kg)
=460.5 × 0.057 x 14
= 367.48 joules
Hence, heat absorbed by iron will be 367.48 joules
Answer:
480 m
Explanation:
If the shoe is falling for 6 seconds and the helicopter is falling at 80 m/s you would mutiply 6*80=480
hope this helped !
