Explanation:

The way to calculate this

  speed of light =  wavelength * frequency

   3 x 10 ^8 m/s   =   wavelength * 2450000000 Hz

       wavelength = .12245 meters

                    = 1.2245 x 10^-1  Meters  

The wavelength of a microwave with a frequency of 2450 mhz is 1.2245 x 10⁻¹ meters.

The wavelength is the time period or spatial period between the periodic wave and the distance between two waves. A microwave is a form of electromagnetic radiation.

The frequency of a microwave, f = 2450 MHz

We need to find the wavelength and the period of the microwaves

c = f λ

c = speed of light = 3 x 10 m/sec. 8 c = λf where λ = wavelength, f = frequency. Length

The relation between the wavelength and frequency is given by

The speed of light =  wavelength x frequency

3 x 10⁸ m/s   =   wavelength x 24500 Hz

Wavelength = .12245 meters

1.2245 x 10⁻¹  Meters  

Therefore, the wavelength of a microwave with a frequency of 2450 MHz is 1.2245 x 10⁻¹ meters.

0.216 moles of gas can the container hold if a sealed container can hold 0.325 L of gas at 1.00 atm and 293 K.

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

V=5 L

P = 1.05 atm

T = 296 K

Putting value in the given equation:

[tex]\frac{PV}{RT}=n[/tex]

[tex]n= \frac{1.05 atm\; X \;5 L}{ 0.08206 L.atm / mol K X 296 K}[/tex]

Moles = 0.216 moles

The relation between the speed of impact and the dropping height is

[tex]\rm h =\dfrac{1}{2g}v^2[/tex]

It is defined as the speed of an object when it falls from a height  and makes an impact with the ground or any other object.

As the object is falling from the height , its velocity will be continuously changing

Assuming it has no initial velocity , u = 0

let the final velocity is  [tex]\rm v_f[/tex] = [tex]\rm \sqrt {2gh}[/tex]

the potential energy at the height  h as  mgh

the kinetic energy when it reaches the bottom as  [tex]\rm \dfrac{1}{2}mv^2[/tex]

As the energy is always conserved

 [tex]\rm mgh = \dfrac{1}{2}mv^2[/tex]

[tex]\rm h =\dfrac{1}{2g}v^2[/tex]

Answer:

B. Mixing a few teaspoons of salt into the water

Explanation:

Pure water doesn't contain any ions, therefore it cannot conduct electricity. Adding salt (NaCl) to the water causes the salt to ionize into Na⁺ and Cl⁻ ions, and the movement of the ions completes the circuit, causing the bulb to glow.

The thickness of the walls of each hollow lump of iron ore is: 0.295cm. This is determined using the knowledge of the Volume of a Hollow Sphere.

The formula for the Volume of a Hollow Sphere is give as:

Volume of a Hollow = 4/3 R³ – 4/3 r³

Step 1 - Find the apparent volume of 8cm diameter sphere including the wall the the hollow inside

V = 4/3 r³

V = (4/3) (8)³

V = (4/3) * (22/7) * 512

V = 2145.52cm³

Step 2 - Determine the mass of Gold required for the sphere to achieve the density of iron ore if the apparent volume is as given in Step 1 above.

Recall that Mass = Density * Volume

Mass = 5.15 *  2145.52

Mass = 11049.45

Step 3 - Find volume of gold based on mass calculated in Step 2 above

Recall that :

Volume = Mass/Density

Thus,

V = 11049.4/19.3

Thus, Volume = 572.51cm³

Step 4 - Find the width of the wall of a hollow sphere for the volume realized in step 3

Recall the initial formula:

Volume of a Hollow = 4/3 R³ – 4/3 r³

Thus, 572.51 = (4/3) (8³ - (8 - t)³)

572.51 = (4/3) *(22.7) *(8³ - (8 - t)³)

572.51 = (88/21) *(8³ - (8 - t)³)

Multiply both sides by 21 and we have

88 (512 - (8 - t)³) = 12,022.71

Simplify further
(8 - t)³ = 357.38

t = 0.9035cm

Explanation:

The answer to this question is A. Both ripening and spoiling are chemical reactions.

Spoiling is a chemical reaction because spoiled food has bad smell and taste and it changes colour too.

Ripening of fruits is a chemical change. For example the colour could change as well as the texture.

Answer:

option a) chemical reaction, chemical reaction.

Explanation:

Changes in which new substances with different properties are formed are called chemical changes. Cooking of food, burning of substances are chemical changes as entirely new substances are formed. Burning of a candle wax releases carbon dioxide and water vapour (new substances). in here ripening and spoiling is a change that cannot be reversed which makes it a chemical change.

5. The amplitude of the ripples decreases as the circumference of the circle increases.

A wave is a disturbance that moves energy from one place to another.

Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.

As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.
