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.

<span> <span> The answer to your question is: increase the force applied to the object.
Two items are provided as a basis for that conclusion:
1. According to Newton's Second Law of Motion, the formula for finding force is: F = ma
where F is the force,
m is the mass of an object,
and a is the acceleration of the object.
And 2: work = force x distance or W = F x d.</span></span>
Answer:
39.2m/s
Explanation:
The potential energy the book has right before it falls is equal to the kinetic energy in falling.
PE = KE
mgh = (1/2)mv
2gh=v
v=(2)(9.81)(2)
v=39.24m/s
Answer:
The answer is "
"
Explanation:
The formula for velocity:
Answer:
Explanation:
a )
change in the gravitational potential energy of the bear-Earth system during the slide = mgh
= 45 x 9.8 x 11
= 4851 J
b )
kinetic energy of bear just before hitting the ground
= 1/2 m v²
= .5 x 45 x 5.8²
= 756.9 J
c ) If the average frictional force that acts on the sliding bear be F
negative work done by friction
= F x 11 J
then ,
4851 J - F x 11 = 756.9 J
F x 11 = 4851 J - 756.9 J
= 4094.1 J
F = 4094.1 / 11
= 372.2 N
