Fist one is a cylinder
the second, i believe is a sphere
the third is a rectangular prism
and the last is the same as the first, a cylinder
Ick! Word problems! They suck. Okay so first of all you want to narrow it dow the equation.
Step 1. What are the numbers? (In this case 12 m/s and 25 m/s)
Step 2. Are you multiplying, dividing? (In this case your dividing)
Step 3. Divide.
I hope that helps.
Answer:
Speed = 2.25 m/s
Explanation:
(Assume a running step is 1.5 m long)
Given the following data;
Energy = 0.6J
Power = 61 Watts
Mass = 68 kg
To find how fast the person running;
First of all, we would determine the total mechanical energy being dissipated by the person.
Total energy = 0.6 * 68
Total energy = 40.8 Joules
Next, we find the time;
Energy = power * time
40.8 = 61 * time
Time = 61/40.8
Time = 1.5 seconds
Finally, to find the speed;
Speed = distance/time
Speed = number of steps * time
Speed = 1.5 * 1.5
Speed = 2.25 m/s
The electric field at arbitrary point outside the sphere is determined as the E = σr³/k.
<h3>Electric field determined from Gauss law</h3>
The electric field of the surface is determined from Gauss law as shown below;
E ∫ds = Q/ε
E (4πr²) = Q/ε
E = Q/4πεr² . r
<h3>Electric field outside the sphere with dielectric with polarization</h3>
where;
- σ is dipole moment of atom of the metal
- k is dielectric constant
Thus, the electric field at arbitrary point outside the sphere is determined as the E = σr³/k.
The complete question:
A metal sphere of radius R carries a total charge Q. outside the sphere is a dielectric with polarization p(f) k/r^3er. Determine the electric field at arbitrary point outside the sphere.
