Answer:
Check the explanation
Explanation:
1) Pressure acting on the plug = Patm + P
Pressure = Patm + rho*g*h (Here h = D2)
Pressure = 101325 + 1000*9.8*7
Pressure = 169925 Pa
so, Force = PA
Force = 169925*pi*0.0152
Force = 120.1 N
Answer:
The value is
Explanation:
From the question we are told that
The mass of the car is
The acceleration is 
Generally the net force applied on the rope is mathematically represented as

Here W is the weight of the car which is evaluated as
=> 
=> 
Generally the net force can also be mathematically represented as
So

=> 
=>
If it is in its ground state, it will be in the level 1s
it's caused by a pressure that is large on the button of an object that it is on the top of an object submerged in a liquid.
Explanation:
This is why object appear to weigh less when immersed in a liquid. If the upthrust is greater than the weight of the object, the object will rise up through the liquid.
