Answer:
See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
Answer:
thickness of ice melted = 1.242*10^{-3} m
Explanation:
power delivered = V*I = 12 * 28 = 336 Watts
.
heat delivered = power * time = 336 W * 300 seconds = 168000 Joules
.
mass of ice melted
mass of ice melted = 97200 J / 335000 J/kg = 0.5014 kg
.
volume of ice melted = mass / density = 0.5014 / 917 = 5.46*10{-4} m3
.
thickness of ice melted = volume / area = 5.46*10{-4} / 0.44 = 1.242*10^{-3} m
8m becoz when the distance increases the gravitational strength also increases
