Answer:
Horizontal distance=?m
Explanation:
Horizontal velocity,u=482ms⁻¹
Height of the cliff=17.7m
Horizontal distance,R=?
R=v×√2h/g
At normal temperature,
specific heat of air = 1.006
concrete =0.96
water =4.187 (all are in KJ/KgK)
soil = 0.80
So, from <span>Q=mcDeltaT</span><span>
higher the specific heat lower the change in temperature for same quantity of heat supplied.
Therefore, water is the answer.</span>
Answer:
Explanation:
Dimensions of mattress 100 cm by 194 cm by 14 cm
= Mass of mattress = 4 kg
= Density of water =
g = Acceleration due to gravity =
Volume of mattress
Weight of water displaced is equal to the buoyant force
Mass of water
Mass of person would be
Weight of the person would be
The air mattress could hold a person that weighs up to .
