A hydraulic lift raises a 2000 kg automobile when a 500 N force is applied to the smaller piston. If the smaller piston has an a
1 answer:
Answer:
The cross-sectional area of the larger piston is 392cm ^{2}[/tex]
Explanation:
To find the solution, we apply the following equation:
Pascal's principle: F=P*A Formula (1)
F=Force applied to the piston
P: Pressure
A= Area of the piston
Nomenclature:
Fp= Force on the primary piston= 500N
W= weight of the car =m*g=2000kg*9.8m/s2= 19600N
Fs= Force on the secondary piston= W = 19600N
As= Area of the secondary piston=?
Pressure applied on one side is distributed to all liquid molecules since liquids are incompressible.
From equation (1)
P=F/A
Pp=Ps

Answer:
The typical weight of a human heart is approximately 0.93 lbs.
Explanation:
Based on this,
the heart's weight constitutes about 0.5% of total body mass.
Total human weight = 185 lbs
Let the entire body weight be represented as w and the heart's weight as .
We aim to determine the heart's weight for a human
Using the provided information
Where, h = heart weight
w = human weight
The final weight of a human heart is 0.93 lbs.
In the study of physics, Hooke's law can be expressed as:
F = kx
This law indicates that the spring force F is proportional to the extension x, with k being the spring constant.
In experiments, this is often examined using the setup illustrated in the included figure. The spring is tested, and a known weight is applied underneath it. This weight exerts a gravitational pull, essentially its weight, on the spring. While the spring elongates, the displacement can be measured using a ruler.
Several potential errors can arise during this experiment. Firstly, the person's measurement reading may be faulty. Digital scales offer greater accuracy as they reduce human error, while ruler readings can be subjective, especially if not viewed at eye level. Additionally, the object's weight may be inaccurately measured if the scale is untrustworthy. Lastly, the measuring equipment may not be correctly calibrated.
