Since speed (v) is in ft/sec, let's convert our diameters from inches to feet:
1) 5/8in = 0.625in
0.625in × 1ft/12in = 0.0521ft
2) 0.25in × 1ft/12in = 0.021ft
Equation:
new velocity coming out of the hose then is
44 ft/sec
1) 5/8in = 0.625in
0.625in × 1ft/12in = 0.0521ft
2) 0.25in × 1ft/12in = 0.021ft

Answer:
Magnetic force,
Explanation:
It is given that,
Velocity of proton,
Angle between velocity and the magnetic field, θ = 53°
Magnetic field, B = 0.49 T
The mass of proton,
The charge on proton,
The magnitude of magnetic force is given by :
So, the magnitude of the magnetic force on the proton is . Hence, this is the required solution.
The escape velocity from the planet is 5052 m/s
Explanation:
The formula to calculate the escape velocity from a planet is:
where
is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For Earth,
is the mass
is the radius
Here we have a planet that:
- its mass is 10.8% of that of Earth, so
- its radius is 53% of that of Earth, so
Substituting everything into the first equation, we find the escape velocity from this planet:
