Suppose your rub a balloon in your hair and it acquires a static charge of −2 × 10⁻⁹c. what is the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon? Coulomb’s constant is 9 × 10⁹ N · m²/c² . Answer in units of N/C
Answers
Given that the charge of the balloon is -2 × 10^(-9) C and the distance from the balloon is 1 m, we can substitute these values into the equation:
E = (9 × 10^9 N · m²/C²) * (-2 × 10^(-9) C) / (1 m)^2
Note that the negative sign indicates the direction of the electric field, which in this case is due north.
E ≈ -18 N/C
Therefore, the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon is approximately 18 N/C.

The weight of 20 kg is
(mass) x (gravity) =
(20 x 9.8) = 196 newtons, downward.
There must be a force of 196 newtons upward on the mass.
Otherwise the mass is accelerating either up or down.
Answers
air resistance, then vertical acceleration is always 9.8 m/s²
downward, and horizontal acceleration is always zero.
My apex test just corrected my original answer of 9.8 m/s^2 to 0 m/s^2.

The work is an effect that is observed due to the application of force. Taking the concern of work-energy principle, the work is done when there is a transfer of energy take place.
What is Work Done?
When some magnitude of the force is being applied on an object to displace, then the term used to describe the effect is known as work done.
The mathematical expression for the work done is given as,
W = F × d
here,
F is the magnitude of applied force.
d is the displacement.
If we compare work with energy then, Energy, on the other hand, is the ability to do work. According to the work-energy principle, a change in the kinetic energy is equivalent to the net work done by the object. Therefore, energy is being transferred from one point to another when work is being done.
Thus, we can conclude that the work is done when a transfer of energy takes place.

Answer;
Energy is being transferred
Explanation;
- Work is the force applied over a given distance, in other words work is the product of force and distance.
Work = force × distance.
- Work is measured in Joules.
- Energy on the other hand, is the ability to do work.
- According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.
G. Heat from the sun reaches your skin by conduction.
H. The Suns energy is conducted to your skin by the glass
I. Heat from the room is reflected from the Windows onto your skin
Answers
We know it's NOT G., because conduction requires some pathway that actually CONNECTS to us, and a window can't "connect" to us.
H. is the same reason as G., and the problem didn't state that it touches or "connects" to us.
So that leaves only to A., and YES, it could reach our skin through radiation!
