The answer is "The force between two charges and the distance separating them".
Coulomb's Law is written as:
In which
is the force felt between two charges,
is the charge of one particle,
is the charge of the other particle,
is the distance separating them, and
is a constant.
Answer:
To reach the goal to be Eco friendly, the designer must not harm the ecosystem of surrounding in any ways.
Explanation:
- Friendly design means that the hotel must not harm the surrounding ecosystem in any way.
- The hotels' energy consumption shall be fulfilled by the use of renewable resources like solar, wind energy, etc.
- Proper disposal of wastage is the most important term.
- No, chemicals are used inside the premises of the hotel for any purpose of cleaning, washing, etc.
- The designer must place a garden with grass, trees, and flowers for the fresh air of the hotel.
<h3><u>Answer;</u></h3>
D. Longitudinal waves
<h3><u>Explanation;</u></h3>
- A wave is a transmission of a disturbance from one point to another. It involves the transmission of energy from a source to other points.
- <em><u>Waves may classified as longitudinal waves or transverse waves depending on the vibration of particles relative to the wave motion.</u></em>
- <em><u>Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion, while transverse wave are types of waves in which the vibration of particles is perpendicular to the wave motion.</u></em>
- Longitudinal waves creates regions of compressions and rarefactions, while transverse waves creates regions of maximum displacement called crests and troughs
Answer:
Fourth option
Explanation:
They're many different types of energy, from chemical and mechanical to heat and solar energy. But the two most basic types of energy are "kinetic and potential energy" or the fourth option. Kinetic energy is the energy an object has when it is in motion, while potential energy is the energy an object has when it's as rest. These two specific types of energies are the most basic and you can even convert them into many different types of energies, like heat or electrical energy.
Hope this helps.
The change in mean drift velocity for electrons as they pass from one end of the wire to the other is 3.506 x 10⁻⁷ m/s and average acceleration of the electrons is 4.38 x 10⁻¹⁵ m/s².
The given parameters;
- <em>Current flowing in the wire, I = 4.00 mA</em>
- <em>Initial diameter of the wire, d₁ = 4 mm = 0.004 m</em>
- <em>Final diameter of the wire, d₂ = 1 mm = 0.001 m</em>
- <em>Length of wire, L = 2.00 m</em>
- <em>Density of electron in the copper, n = 8.5 x 10²⁸ /m³</em>
<em />
