A wave is a disturbance in a medium. It is a product of wavelength and frequency, and time period of a wave is the reciprocal of frequency of wave.

A wave is a disturbance in a medium which carries energy without a net movement of particles in the medium. Wave may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, or temperature.

Speed of a wave = wavelength of the wave × Frequency of the wave

3. Frequency = 2 Hz, Wavelength = 5 m.

Speed of the wave = wavelength × Frequency

Speed of the wave = 2 × 5

Speed of the wave = 10 m/s

4. Speed of wave = 50 m/s, wavelength = 3 m

Speed of wave = wavelength of the wave × Frequency

frequency = Speed of wave/ wavelength

Frequency of wave = 50/3

Frequency of wave = 16.66 Hz.

5. Speed of wave = 30 m/s, wavelength = 3 m,

Frequency of wave = Speed of wave/ wavelength

Frequency of wave = 30/3

Frequency = 10 Hz.

6. Time period = 2 seconds, wavelength = 4 meters,

Frequency of wave = 1/T

Frequency = 1/2

Frequency = 0.5 Hz,

Speed of wave = Wavelength × Frequency

Speed of wave = 4 × 0.5

Speed of wave = 2 m/s

7. Speed of wave = 330 m/s, wavelength = 2 m

Frequency = ?

Time period = ?

Speed of wave = Wavelength × Frequency

Frequency = Speed of wave/ Wavelength

Frequency = 330/2

Frequency = 165 Hz,

Time period = 1/f

Time period = 1/165

Time period = 0.0060 seconds

8. Wave A: Frequency = 250 Hz, wavelength = 30 cm,

Wave B: Frequency = 260 Hz, wavelength = 25 cm,

Time period of Wave A = 1/ 250

Time period of Wave B = 1/ 260

Time period of Wave B is less than time period of Wave A. Therefore, Wave B is faster than Wave A.

9. Number of waves = 10, Total time = 40 seconds,

Therefore, time period = Number of waves/ Total time

Time period = 10/ 40

Time period = 1/4

Time period = 0.25 seconds.

Answer:

see below

Explanation:

Distance = 5100m

time = 1min = 60s

avg speed= distance/time

v = 5100m/60s

v = 85m /s

so the plane was traveling a average distance of 85m per second.

The volume of 60c is 1333.33 ml

The volume of a gas is directly proportional to its temperature, provided the pressure remains constant. The equation for this relationship is:

V1 / T1 = V2 / T2

where

V1 is the initial volume,

T1 is the initial temperature,

V2 is the final volume, and

T2 is the final temperature.

when V1 = 600 ml and T1 = 27°C, we can solve for V2:

V2 = (V1 * T2) / T1

V2 = (600 ml * 60°C) / 27°C

V2 = 1333.33 ml

Using algebraic expressions, the constant acceleration is represented as 2(d/4)/t^2 and the ratio of the the average velocity is 8/t

A. To meet the puck one quarter of the distance from where you started, you need to cover one quarter of the total distance that the puck travels.

Let's call the initial distance between you and the puck "d". Then, the total distance the puck travels is d, and the distance you need to cover is d/4.

The time it takes for the puck to travel d is d/8 (since the puck's velocity is 8 m/s). The time it takes for you to cover d/4 is t.

Using the equation of motion, we can find the acceleration needed:

d = (1/2)at^2

d/4 = (1/2)(a)t^2

(1/2)(a)t^2 = d/4

a = 2(d/4)/t^2

We don't know the value of "d", so we cannot calculate the exact value of "a". But we can find it in terms of "t".

B. To calculate the ratio of your average velocity to the puck's constant velocity, we can use the equation:

v(average) = d/t

Let's call your average velocity "v". Then,

v/8 = d/(4t)

v/8 = d/4 * 1/t

v/8 = v(average)/t

v/8 = v(average)/t

v/v(average) = 8/t

Again, we don't know the value of "d" or "t", so we cannot calculate the exact value of the ratio. But we can represent it in terms of "t".

Explanation:

The amount of work done by the man in pushing the mower 5.7 m can be calculated using the following formula: Work = Force x Distance. Therefore, the amount of work done by the man in this case can be calculated as: Work = 211 N x 5.7 m = 1201.7 N.m.

A way of stating this motion is that the planet is accelerating towards the Sun and decelerating away from it.

This is because the gravitational force of the Sun is stronger when the planet is closer, and weaker when the planet is further away. As a result, the planet's speed changes as it moves along its orbit.

Planets orbit around the Sun in an elliptical path, which is shaped like an oval. This path is determined by the gravitational force of the Sun on the planet. The closer the planet is to the Sun, the faster it moves, and the further away it is, the slower it moves. This means that the planets can be closer or further away from the Sun depending on their position in their orbit. As the planets orbit the Sun, their distance from the Sun changes, and this causes the seasons on Earth.

The given statement about “When infrared radiation is absorbed by a greenhouse gas molecule the infrared radiation can never leave Earth atmosphere” is false, because the circulating infrared radiation in the atmosphere will eventually escape into space.

Greenhouse gases are needed in order to maintain a temperature on our planet that is suitable for the continuation of life. Without the natural greenhouse effect, the heat that the Earth radiates into space would simply escape outwards from the surface of the planet, and the average temperature of the planet would be somewhere about -20 degrees Celsius.

Because it emits energy into space as infrared radiation, which is invisible to the human eye, the Earth does not get hotter and hotter as it receives energy from the sun. The Earth must emit an amount of infrared radiation that is equal to the amount of energy that is absorbed from sunlight in order for there to be an energy balance.

Explanation:

Given that the metal chloride formula is MC13, we can assume that the metal (M) is represented by the atomic symbol "M" and the atomic weight of chlorine (Cl) is 35.5.

Since 20% of the total weight of the compound is the metal, the atomic weight of the metal (M) can be calculated as:

M = (0.2 * (13 * 35.5 + M)) / 13 = 0.2 * 35.5 + 0.2 * M

Solving for M:

0.2 * M = (0.2 * 35.5) / (1 - 0.2) = 7.1

M = 7.1 / 0.2 = 35.5

So the atomic weight of the metal (M) is 35.5, and the answer is (b) 56.

Answer:The answer is "when it is in the air" because when objects are positioned higher off the ground they have more gravitational potential energy.

Explanation:

Newton's law of cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings. This relationship can be mathematically modeled using a first-order ordinary differential equation.

The general form of the equation for Newton's law of cooling is:

[tex]dT/dt = k(T_s - T)[/tex]

where T is the temperature of the object, [tex]T_s[/tex] is the temperature of its surroundings, k is the constant of proportionality known as the cooling rate, and t is time.

To solve this differential equation, we need to find the function T(t) that satisfies the equation. One method to solve this equation is to use the method of separation of variables. We separate the variables T and t, integrate both sides, and then solve for T.

The solution to this differential equation gives us the time-dependent temperature of the object as it cools down to the temperature of its surroundings. This solution is useful in understanding the cooling process of objects in various real-world scenarios such as heat transfer in electronics, refrigeration, and air conditioning systems.

A scalar is a single quantity that has magnitude but no direction. It is typically represented by a real number and is used to measure the magnitude of a physical or mathematical quantity. Examples of scalars include speed, temperature, mass, energy, and volume. Scalars are contrasted with vectors, which have both magnitude and direction.

T(Su) = (25, 5)

T(_9v) = (-45, 27)

T(Su 90) = (-225, -45) with explanation:

To calculate T(Su), we use the fact that T is linear, meaning it respects the distributive, associative, and scalar multiplication properties. Therefore, we can break down the expression into its constituent parts, T(S*u), which can be written as: T(S) * T(u).

Since S is a scalar (90) and u is a vector (5,2), we can calculate T(S) as 90*T(u) and T(u) as (2,1). Therefore, T(S*u) = 90*(2,1) = (180, 90).

To calculate T(_9v), we use the same principle and break down the expression into its constituent parts, T(_9)*T(v). Since _9 is a scalar and v is a vector (1,3), we can calculate T(_9) as -9*T(v) and T(v) as (-1,3). Therefore, T(_9v) = -9*(-1,3) = (-45, 27).
