Answer:
Power = 50204 [watts]
Explanation:
We know that the power is defined by the following expression:
Power = Work/time
where:
Power [watts]
time [seconds]
The work done will be the following:
Work = Force * distance [Joules]
Force[Newtons]
distance[meters]
Force = mass* gravity
Force=290 [kg]*9.81[m/s^2] =2844.9[N]
Work = 2844.9[N]*300[m] = 853470[J]
Therefore
Power = 853470 / 17 = 50204 [watts]
Answer:
second lag
Explanation:
If in a cup game, a specified time limit is assigned to both teams to score high. If both teams are unable to score or if score of both the teams is equal then there is another second lag played where each team tries to score high. Even if in second lag both teams fail to score higher than other the last third lag is played or else game is declared draw.
The mass of the iceberg is 71.9 kg
Explanation:
The amount of thermal energy needed to completely melt a substance at its melting point is given by
where
is the latent heat of fusion
m is the mass of the substance
In this problem, we have a block of ice at its melting point (zero degrees). The amount of heat given to the block is
And the latent heat of fusion of ice is
So, we can re-arrange the equation to find m, the amount of ice that will melt:
