Answer:
y = 2.45 x
Explanation:
given,
Let 'x' be the number of cans.
and 'y' be the total area of the room
now,
From the given statement in the question
y = 2.45 x
From the Above equation we can state that
To pain the entire room 2.45 cans of paint is required.
The answer is A. Alternating current regularly reverses direction. Direct current flows in only one direction.
Answer: 
Explanation:
The density 
of a material is given by:
(1)
Where:
is the mass of the cube
is the volume of the cube
Now, the volume of a cube is equal to the length 
of its edge to the power of 3:
(2)
If we know 
, the volume of this cube is:
(3)
Substituting (3) in (1):
(4)
This is the density of the cube
Rotation during thawing is necessary to ensure that your food reaches the right temperature in a secure and efficient manner. This prevents the ice from becoming stuck under some of the food. By rotating it, you can reveal any trapped, covered, or chunked ice.
<h3>What do you mean by Microwave oven?</h3>
- A microwave oven, often known as a microwave, is an electric oven that uses electromagnetic radiation with a microwave frequency range to cook and heat food.
- As a result, the food is heated via a process known as dielectric heating, which causes the polar molecules there to rotate and produce heat energy.
- Because excitation is rather homogenous in the exterior 25–38 mm (1–1.5 inches) of a homogeneous, high water content food item, microwave ovens heat food fast and effectively.
<h3>What are the uses of a microwave oven?</h3>
- A microwave oven, sometimes known as an electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food.
- A microwave oven is a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.

Electromagnetic waves are produced by light. They are made up of oscillating magnetic and electric fields. They include radio waves, microwaves,infrared waves, visible light, ultraviolet, x-rays and gamma rays. Electromagnetic waves carry energy. radio waves are used in communications to send signals from one place to another.Microwaves use high energy that increases the motion of molecules in your food. Infrared waves are used in things like night vision cameras or a tv remote. The human body has a temperature that produces radiation which can be picked up by an infrareds device.Ultraviolet light ( like from the sun) can cause sunburn and skin cancer . That.s why it’s important to wear sunscreen and sunglasses to protect our bodies and and our eyes. X-rays are very high energy and like ultraviolet rays can cause damage to the body. But x-rays used at the right amount can be safe on the tissues and organs in our bodies. Hope this helps !
