When gasoline is burned in the cylinder of an engine, it creates a high pressure that pushes the piston. If the pressure is 100.

Marianna [84]

Answer:

$\dot W=2.1074\ hp$

Explanation:

Given:

pressure on the piston, $P=100\ psi=689476\ Pa$

diameter of the piston, $d=3\ in=0.0762\ m$

displacement of the piston, $s=0.05\ m$

time taken in the piston displacement, $t=0.1\ s$

Now, we find the force on the piston:

$F=P.A$

where, A = area upon which pressure acts

$A=\pi.\frac{d^2}{4}$

$A=\pi.\frac{0.0762^2}{4}$

$A=0.00456\ m^2$

$\therefore F=689476\times 0.00456$

$F=3144.2638\ N$

we know that Power is given as:

$\dot W=\frac{F.s}{t}$

$\dot W=\frac{3144.2638\times 0.05}{0.1}$

$\dot W=1572.1319\ W$

$\dot W=2.1074\ hp$

A 120 V electric heater draws a current of 14.1 A. What is the resistance, in ohms?

Sav [38]

Answer:

8.5 ohms

Explanation:

from ohms law

V=IR

120=14.1R

divide both sides by 14.1

120/14.1=14.1R/14.1

R=8.5ohms

What will be the mass of a body at the center of the earth as compared to other places on

Eduardwww [97]

The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.
