Answer:
F1= 122.93 N
Explanation:
Pascal´s Principle
Pascal´s Principle can be applied in the hydraulic press:
If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:
P=F/A
P1=P2
Formula (1)
Data
D1 = 1.85 cm : primary cylinder piston diameter
D2 = 24.5 cm : secondary cylinder piston diameter
m = 2200-kg : car mass
Piston area calculation


A1= 2.688 cm²


A2 = 471.435 cm²
Calculating of the weight of the car (W)
W = m*g = 2200-kg * 9.8 m/s² = 21560 N
Calculation of the force in Newtons to be exerted on the primary cylinder piston
Data:
A1= 2.688cm²
A2= 471.435 cm²
F2 = W= 21560 N
We replace data in the formula (1)


F1= 122.93 N
Answer: Looser muscle
Explanation: If your muscle are tight all the time it’s unhealthy and can cause cramps all the time rather than loose muscles that are relaxed
The most important thing you should remember in order to get how is its linear momentum relative to the surface is that the<span> point on the circumference is moving at w rad/second.
Therefore, here is the solving formulae:
if </span>

you can easily get <span> linear momentum p :
</span>

I'm sure that helps.
Answer:
162.78 m/s is the most probable speed of a helium atom.
Explanation:
The most probable speed:

= Boltzmann’s constant =
T = temperature of the gas
m = mass of the gas particle.
Given, m = 
T = 6.4 K
Substituting all the given values :


162.78 m/s is the most probable speed of a helium atom.
