If the speed of the wave along the rope is 3.2 m/s. Calculate the frequency of the wave​

Answer:

The answer is below

Explanation:

When a gallon is blown the air energy is saved as potential energy which is compressed inside the balloon. However, when the balloon is released without trying its neck, the air energy quickly turned to kinetic energy, in which the air energy keeps moving as the balloon float around the space.

Hence, in short, what happens in terms of energy when you blow up a balloon and release it without trying its neck​ is that the air energy moves from potential energy to kinetic energy.

Answer:

1.2×10⁶ Hz

Explanation:

Applying,

v = λf............. Equation 1

Where v = speed of wave, λ = wavelength, f = frequency.

make f the subject of the equation

f = v/λ............... Equation 2

From the question,

Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m

Substitute these values into equation 2

f =  3.0×10⁸/2.5×10²

f = 1.2×10⁶ Hz

Answer:

Saturn's rings are thought to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet, they are made of billions of small chunks of ice and rock coated with another material such as dust.

C. An article written by a scientist

Explanation:

Research-based original articles written by a scientist can act as a primary source of information. Textbooks, dictionaries and encyclopedias are generally classified as secondary sources and are rarely primary sources.

How was the result of your physical fitness test in Flexibility and muscular

strength compared to your previous assessments?

Explanation:

Answer:

78 m

Explanation:

Initial v = 1 m/s

a = 4 m/s²

t = 6s

[tex]x = v_{i} t + \frac{1}{2}at^{2} \\x = (1)(6) + \frac{1}{2} (4)(6)^{2} \\x = 6 + 72\\x = 78[/tex]

Answer:

Explanation:

Time for one dot = 1 /50 = .02 s

Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s

velocity = 3 cm / .02 = 150 cm /s

Distance between 4 th and 5 th  dot is 4 cm and time taken to travel this distance is .02 s

velocity = 4 cm / .02 = 200 cm /s

change in velocity = 200 cm/s  - 150cm/s = 50 cm /s

Time taken = .02 s

Acceleration = 50 / .02 cm/s²

= 2500 cm/s²

Answer:

   I = 2.667 kg m²

Explanation:

The moment of inertia of a body can be calculated by the expression

         I = ∫ L² dm

For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is

         I = [tex]\frac{1}{12}[/tex] m L²

let's calculate

         I = [tex]\frac{1}{12}[/tex]  2  4²

         I = 2.667 kg m²

Answer:

[tex]3 \times {10}^{8} m {s}^{ - 1} [/tex]

Answer:

faster than u

Explanation:

Answer:

Efficiency = 80%

Explanation:

Given the following data;

Work output = 240 N

Work Input = 300 N

To find the mechanical efficiency of a machine;

[tex] Efficiency = \frac {Out-put \; work}{In-put \; work} * 100 [/tex]

Substituting into the equation, we have;

[tex] Efficiency = \frac {240}{300} * 100 [/tex]

[tex] Efficiency = 0.8 * 100 [/tex]

Efficiency = 80%

Therefore, the mechanical efficiency of the machine is 80 percent.

Answer:

Atoms of elements with the same electons in the outer most shell they are put in the same group on the periodic table

Answer:

The first law of thermodynamics states that the change in the internal energy of a system equals the net heat transfer into the system minus the net work done by the system. This is another way of saying that energy can neither be created nor destroyed, but it can be converted from one form to another form.

A tea kettle that is warmed on an electric stove is receiving heat energy, this heat energy increases the kinetic energy of the water particles in the kettle and makes them to move faster. As time goes on, the water begins to turn into vapors. The heat energy that is released into the system is been used to carry out the work of evaporation and the whistling of the kettle.

Explanation:

1/1000

If a foot is 1/3 of a yard the 1/1000 part of a meter is a millimeter, therefore the correct answer is option D.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

Any additional quantity of that type can be stated as a multiple of the measurement unit.

As given in the problem a foot is 1/3 of a yard then we have to find out what part of a meter is a millimeter,

1 meter = 100 centimeters

1 centimeters = 10 millimeters

1 meter = 100×10 millimeters

1 meter = 1000 millimeters

1 millimeters = 1/1000 meter

Thus, the 1/1000 part of a meter is a millimeter, therefore the correct answer is option D.

fission is the process of electrons from atoms coliding into other atoms which releases more electrons and when done right releases lots of energy.

fusion is the process of using intense heat and electromagnetic forces to force electrons to bind to atoms which releases lots of energy

Acceleration is the time rate of change in velocity.

Acceleration = Rate of change of velocity
