Answer:

C. infrared waves

Explanation:

Microwaves are the electromagnetic waves which would the best to use in an object designed to cook food. Thus, the correct option is D.

Microwave is a form of electromagnetic radiation with the wavelengths ranging from about one meter to about one millimeter which is corresponding to the frequencies in the range between 300 MHz and 300 GHz, respectively.

Microwaves are used for cooking food faster than the conventional ovens and would not make a mess in the process. This reheats food instantly quickly. It is helpful for the health conscious people. Microwaves also ensure that a person will never burn the food again. Microwaves are also very economical and energy efficient.

Therefore, the correct option is D.

Answer:

32 m

Explanation:

By energy conservation, total energy at the top of slide must be equal to the total energy at at the bottom.

therefore

mgh = (1/2)mv^2

v^2= 2gh

[tex]v = \sqrt(2gh)[/tex] ..............(1) i.e., velocity is a function of height of slide.

1st part

Let height of blue slide be H and height of red slide be h.

Let velocity of rider in blue slide= V and red slide= v

At the bottom of slide,

From equation (1)

therefore  

[tex]\frac{V^{2}}{v^{2}} = \frac{2gH}{2gh}[/tex]

Given, V= 2v  

[tex]\therefore  \frac{4v^{2}}{v^2{}} = \frac{H}{h}[/tex]

H = 4h

therefore, height of blue slide is 4 times that of red slide= 4*8=32 m

Answer:

its c

Explanation:

Answer:

15%

Explanation:

Step one:

Given data

Energy source= 300J

Useful energy = 45J

Waste energy = 255J

Required

The efficiency of the solar system

Step two:

The efficiency is computed by factoring only the useful work and the energy source

Efficiency= 45/300*100

Efficiency= 0.15*100

Efficiency= 15%

Answer:

because of the hydrogen bonds, as water molecules come together they stick to one another for a small, but significant amount of time. This slows them down, and holds them closer to one another. They become a liquid; a different state of matter where the molecules are closer and slower than in a gas.

Answer:

When water is in its solid-state, the water molecules are packed close together preventing it from changing shape.

Explanation:

In general, when considering the states of matter, solids are denser than liquids, and normally liquids are denser than gases.

                "relationship between drag force and driving force​"

The velocity at any time during the flight depends on the corresponding acceleration of the vehicle and the balance of forces acting of the vehicle.Forces acceleration and velocity are all vector quantities having both a magnitude and a direction.When describing the motion of an object caused by forces,one must account for both the magnitude and direction.The forces present during coasting flights are the drag and the weight.The weight is constant is magnitude and is always directed toward the center of earth.The magnitude of the drag change the square of the velocity.During ascent the drag is in the same direction as the weight .But during descent the drag opposes the weight.

For the descending rocket the next vertical external force  F is equal to the difference between the drag D and the weight W:

                  F=D-W
