The answer is letter C. 40 N
Answer:
2 meters
Explanation:
time is directly proportional to temperarure where distance is the constant k
therefore
T = t x 2a
28=7 x 2a
28= 14a
a=2m
Answer:3764.282 KPa
Explanation:
Given gusher shoots oil at h=25 m
i.e. the velocity of jet is
v=\sqrt{2gh}[/tex]
v=22.147 m/s
Now the pressure loss in pipe is given by hagen poiseuille equation
For 25 m head in terms of Pressure
Total Pressure==3543.557+220.725=3764.282 KPa
Answer:
The ratio of the escape velocity to the orbital velocity is .
Explanation:
The minimum velocity given to an object so that it escapes from the earth's gravitational pull is called escape velocity.
The formula of the escape velocity is
The velocity of an object in the orbit around the earth is called orbital velocity.
The formula of the orbital velocity is
The ratio of the escape velocity to the orbital velocity is
