Answer:
384N
Explanation:
Given parameters:
Mass = 3kg
radius = 0.5m
Speed = 8m/s
Unknown:
Centripetal force = ?
Solution:
The centripetal force is the inward force that keeps a body in motion along a circular path.
It is mathematically expressed as;
F =
m is the mass
v is the speed
r is the radius
Now insert the parameters and solve;
F = = 384N
Answer:
D remove 1.5 ML of liquid.
Explanation:
Use the Ideal Gas Law to the air in the tire :
( P ) ( V ) = ( n ) ( R ) ( T )
n = ( P ) ( V ) / ( R ) ( T )
P = P gauge + P baro = 31.2 psig + 14.8 psia = 46 psia
P = ( 46 psia ) ( 1 atm / 14.696 psia ) = 3.13 atm
n = ( P ) ( V ) / ( R ) ( T )
n = ( 3.13 atm ) ( 4.6 L ) / ( 0.08206 atm - L / mol - K ) ( 26.0 + 273.2 K )
n = 0.5864 moles
m = ( n ) ( M )
m = ( 0.5864 mol ) ( 28.96 g/ mol ) = 16.98 g
Answer:
The force on the second piston is 5246.5 N .
Explanation:
Area of first piston, a = 3.002 cm^2
Area of second piston, A = 315 cm^2
Force on first piston, f = 50 N
let the force of the second piston is F.
According to the Pascal's law
Answer:
The momentum of the two-block system is 18 kg-m/s
Explanation:
It is given that,
Mass of block A,
Mass of block B,
Velocity of block A,
Velocity of block B, (it is moving in opposite direction)
We need to find the momentum of two block system. It is given by the product of mass and velocity for both blocks i.e.
p = -18 kg-m/s
So, the momentum of two block system is 18 kg-m/s. Hence, this is the required solution.
