A regulation game consists of 7 innings unless extended because of a tie score or unless shortened because the home team needs none or only a fraction of its 7th inning or unless 1 team is leading by 10 runs after 5 innings.
Explanation:
Answer:
Final energy will be 40 KJ
Explanation:
We have given that 30 KJ of the heat is transferred to the water
So
And 5 KJ of heat is lost to the surrounding air
So
So total heat
The paddle-wheel work amounts to 5000 N -m
So work done W = -5 KJ ( as work is done by the paddle wheel )
We know that
We have given initial kinetic energy = 10 KJ
So
So final energy = 30+10 =40 KJ
Answer:
The original speed of the mess kit is 5.65 m/s.
Explanation:
Given that,
Mass of kit =7.0 kg
Mass of first = 3.5 kg
Speed= 5.5 m/s
Speed of other particle part = 7.5 m/s
Angle = 30°
We need to calculate the momentum of first part
Using formula of momentum
Put the value into the formula
We need to calculate the momentum of second part
Using formula of momentum
We need to calculate the total momentum
We need to calculate the original speed of the mess kit
Using formula of momentum
Put the value into the formula
Hence, The original speed of the mess kit is 5.65 m/s.
