Answer:
5.09 cm
Explanation:
using the formula
V = rω where r is radius and ω is the angular speed and V is the speed
ω = 7. 5 rpm = 7.5 × 2πrad / 60 seconds = 0.7855 rad s⁻¹ since one revolution = 2π and 1 minutes = 60 seconds
2.00 cm/s =r ×0.7855 rad s⁻¹
r = 2.00 cm/s / 0.7855 rad s⁻¹ = 2.546 cm
d = 2r =2 × 2.546 cm = 5.09 cm
Answer:
Explanation:
Given
Mass of water is
mass of ice is
Latent heat of fusion
The heat capacity of water is
Suppose water is at and it reaches to to melt the ice
the heat released by water must be equivalent to heat absorbed by the ice
