Answer:
Explanation:
The force exerted on a charged particle due to a magnetic field is given by:
where
q is the charge of the particle
v is the velocity of the particle
B is the magnetic field strength
is the angle between the directions of B and v
In this problem we have:
is the charge of one honey bee
is the velocity of the bee
is the average strength of the Earth's magnetic field
, because the bee flies east to west while the Earth's magnetic field is south to north
Substituting into the equation, we find:
Answer:
0.89 g/cm^3 = 890 kg/m^3
Explanation:
Cross sectional area of U-tube ( A ) = 1.00 cm^2
volume of oil ( V ) = 5.00 cm^3
change between top surface = 0.550 cm
height of oil = 5 cm ( volume / area )
height of water = 5 - 0.550 = 4.45 cm
pressure at the oil-water junction = Pressure on the second side of the U-tube at same level
Po * g * Hoil = Pw * g * Hwater
Po * 5 = 1 * 4.45
∴ Density of oil ( Po ) = 4.45 / 5 g/cm^3 = 0.89 g/cm^3
Answer:
I think so because if it starts at a low temperature for that material, it should melt when you bring it up to that temperature.
Answer:
The tire fills up just like anything else that holds air when u pump a ball or tire up it fills all the way up cause it is a small confined space and after filling it with air the atoms of the air fill the tire up
