Answer:
T = 365.58 K
Explanation:
Given that,
The concentration of solution, C = 0.750M
Osmotic pressure, P = 22.5 atm
We need to find the temperature of the solution.
The formula for the osmotic pressure is given by :
Where
R is gas constant,
So, the temperature of the solution is 365.58 K.
Answer:v
Explanation:
Given
Initially spring mass system is moving towards right with velocity
Now if the spring is released left block moves towards left with a velocity
As there is no external force applied on the system therefore the change in linear momentum is zero i.e. it is conserved
so center of mass continue to move towards the right with velocity v or we can say right block moves towards right with velocity and left block moves with velocity
#1)
1). A point on the outside of a spinning top whose rotational speed is constant.
It will not accelerate as its net speed is ZERO
2). A skydiver whose air resistance is equal to that of her weight.
Since weight is counterbalanced by resistance so here net force is zero so acceleration must be zero here
3). A car on the freeway experiencing a net force of -120 N.
Since there it acts net force F = -120 N so it will accelerate here
4). A submerged beach ball whose buoyant force is eight times the force of gravity on it.
Since buoyant force is more than weight of the ball so it will accelerate upwards
#2)
A non accelerating fra me is always a valid inertial frame
A frictionless spinning merry go round.
(since it is having centripetal acceleration so it is non inertial frame)
A falling rock.
(Since it is falling with acceleration a = 9.8 m/s^2 so it is non inertial)
A hot air balloon moving at 30 degrees east of north with no net force.
(Since net force on hot air balloon is ZERO so it is Inertial Frame)
A space shuttle whose boosters just ignited for takeoff.
(Since space shuttle ignite the boosters so it will accelerate here and hence it is non inertial)
#3
here two forces given as
towards right
towards Left
Since left side applied force is more than right side applied force so net force on it will be towards Left and it is given by
So it is 60 N Left
