Options are. Zenith, Great circle, Equinox, or Meridan
Answer:
F = 351×10³lb
Explanation:
Given the density
ρg = 64.6lb/ft³
Diameter d = 12ft
The tank is horizontally cylindrical. The vertical distance from the top to the bottom of the tank is h = 12ft
The pressure in the tank is
P = ρgh = 64.6 × 12 = 775.2lb/ft²
The force exerted on one end of the tank is therefore F = PA = 775.2 × πd² = 775.2π×12²
F = 351×10³lb.
Answer:
The strength of the electric field is 2.258 x 10⁸ N/C
Explanation:
Potential energy = -p*ECosθ
where;
d is the dipole moment
E is the electric field
θ is the angle of inclination
→When the water molecules is perpendicular to the field, θ =90° and potential energy = p*ECosθ = d*ECos0 = 0
Total potential energy = 0 + 1.40×10⁻²¹J, since it is 1.40×10⁻²¹J more
→When the water molecules is aligned to the field, θ =0°
potential energy = -p*ECosθ
dipole moment, p = 6.2×10⁻³⁰Cm
= -(6.2×10⁻³⁰)*(E) Cos0
0 + 1.40×10⁻²¹ J = -(6.2×10⁻³⁰)*(E),
E = (1.40×10⁻²¹ J)/(6.2×10⁻³⁰)
E = 2.258 x 10⁸ N/C
Therefore, the strength of the electric field is 2.258 x 10⁸ N/C
Answer:
60 m/hr
Explanation:
Remember your equation d=r/t
Plug it in
Or you can think; if a person can run 240 m/hr that means that they can get 1/4 of the way in 1/4 of the time= 60 m
