Answer:
Explanation:
Electrical energy is energy derived from electric potential energy or kinetic energy.
Or,
Electrical energy is a form of energy resulting from the flow of electric charge. Lightning, batteries and even electric eels are examples of electrical energy.People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
Hope it helped you.
The forces acting on your mom while cooking is Air resistance and the force of friction
<u>Explanation:</u>
<u>1. Air resistance:</u>
- In simple words, Air resistance can be stated as the type of friction between the air and the other materials.
- In this scenario, there will be an air resistance and the air hits the mom while cooking via the doors or windows
<u>2. The force of friction:</u>
- In simple words, friction can be stated as, the resistance that one surface or object encounters when moving over another.
- While cooking the food mom would experience the friction since friction is the transfer of heat, and cooking is the process of receiving that heat.
Answer:
A) E = 4.96 x 10³ eV
B) E = 4.19 x 10⁴ eV
C) E = 3.73 x 10⁹ eV
Explanation:
A)
For photon energy is given as:
where,
E = energy of photon = ?
h = 6.625 x 10⁻³⁴ J.s
λ = wavelength = 0.25 nm = 0.25 x 10⁻⁹ m
Therefore,
<u>E = 4.96 x 10³ eV</u>
<u></u>
B)
The energy of a particle at rest is given as:
where,
E = Energy of electron = ?
m₀ = rest mass of electron = 9.1 x 10⁻³¹ kg
c = speed of light = 3 x 10⁸ m/s
Therefore,
<u>E = 4.19 x 10⁴ eV</u>
<u></u>
C)
The energy of a particle at rest is given as:
where,
E = Energy of alpha particle = ?
m₀ = rest mass of alpha particle = 6.64 x 10⁻²⁷ kg
c = speed of light = 3 x 10⁸ m/s
Therefore,
<u>E = 3.73 x 10⁹ eV</u>
Answer:
by moving your hands up and down your we're creating transverse wave which travel in a right angle shape towards your friend
Answer:
Vector quantity
Explanation:
What is a vector quantity?
-> A vector quantity has both direction and magnitude
What is scalar quantity?
-> S scalar quantity has only magnitude
[] Based on these definitions, 9.7 x 104 km East is a vector quantity because it includes a direction, East.
Have a nice day!
