Answer:
total volume is 0.9125 m³
Explanation:
given data
oil = 28 litres
pressure p = 40 MPa
final pressure p2 = 35 MPa
initial pressure p1 = 30 MPa
y = 1,4
to find out
volume of accumulator
solution
so we here say that volume of oil
v3 - v2 = 28 litres
so v3 = 0.028 + v2 ......................a
and volume formula is
v1 = v2 ...................1
so v2 = v3 ..............2
put here value in equation 2
v2 = (0.028 + v2)
v2 = 0.274 m³
and here v1 will be
v1 = 0.274
v1 = 0.3365 m³
and v3 will be
v3 = 0.028 + v2
v3 = 0.028 + 0.274
v3 = 0.302 m³
so
total volume is v1 + v2 + v3
total volume = 0.274 + 0.3365 + 0.302
total volume is 0.9125 m³
Yes. 'Equilibrium' means that the SUM of adding up all the forces acting on the object is ZERO.
If you add up all the forces acting on the object and the sum is NOT zero, then the object is NOT in equilibrium. The force you have to add to it is whatever it takes to cancel out (balance) all the forces that are there now.
Take the SUM you got when you added up all the existing forces. To get equilibrium, ADD ON one new force with the SAME magnitude, in exactly the OPPOSITE direction.

Answer:
Change in momentum,
Explanation:
It is given that,
Mass of the basketball, m = 601 g = 0.601 kg
The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s
It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :
So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
