Boyle's law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 4l , the pressure is 720 kpa (kilopascals). What is the pressure when the volume is 10l ?
Use P=F/a
whereas P= 350000 and a=.9m2
substitute into the formula we get
350000=f/.9m2 multiply .9 on both sides as LHS=RHS WE get 315000 Newtons as the answer
Im pretty sure A-10 b-0 c-40
Answer:
Explanation:
Given
time taken to complete the circle=7.9 s
radius of circle(r)=15 m
velocity of rider is given by
Let us suppose T is the tension in the chain and is the angle which chain makes with vertical
Therefore
--2
Divide 1 & 2 we get
Answer:
6.758V
Explanation:
The computation of the final speed of the defender/ball carrier mass is shown below:-
Data provided in the question
Measurement of ball = 75 kg
Right m/s = 6.5 m/s
Defender = 80 kg
Carrying running 7.0 m/s
Based on the above information, the final speed of the defender or ball carrier mass is
As we know that
Conservation of momentum is
= Ball in Kg × Right m/s + Defender in Kg × running m/s
= 75 × 6.5 + 80 × 7
= (75 + 80)V
Therefore, the Final speed = 6.758V
