The amount of work done by the person is equal to 120 Joules.
<u>Given the following data:</u>
- Displacement = 15 meters.
To calculate the amount of work done by the person at a total height of 2 meters:
<h3>How to calculate work done.</h3>
In Science, work done is calculated by multiplying force and the displacement experienced by an object.
Mathematically, work done is given by the formula:

Substituting the given parameters into the formula, we have;

Work done = 120 Joules.

<span>We calculate the electric field as follows:
r = </span>√<span>(3)/6 x 19 cm = .05484 m
The angle for the triangle would be 30 on each side.
tan(30) = r/(L/2)
E' = kQ/{r*sqrt[(L/2)^2 + r^2]} = (8.99e9 x 15e-9) / {.05484 * sqrt[(.19/2)^2 + .003]}
</span>E' <span>= 22413 N/C
The value above is the electric field strength for a single rod at the center.
|E'| = 22413 N/C
E = 2|E'|sin(30) + |E'| = 49000 N/C</span>
Answer:
a circular path
Explanation:
In a magnetism field if a charged particle having a charge of magnitude '' enters such that its velocity vector V is 90° to the direction of the magnetic field "B'', then it will experience a force, called Lorentz force F

According to the property of cross-product, the Lorentz force (F) acting on the particle will be perpendicular to the instantaneous position of the particle, making the path of the particle to be a circular path.
Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)
Explanation:
We know that m = 5 kg
a = 3.0 m/s^2
g = 9.8 (since not written, lets assume it's an international standard)
T - mg = ma
T = mg + ma
T = (5 . 9.8) + (5 . 3 )
T = 49 + 15
T = 64 N
