Answer: At the antinodes of a standing wave, the wave is shaking very rapidly, causing those parts of the pizza to get hot. At the nodes, the wave is not shaking much at all, causing those parts of the pizza to stay cold."

Explanation:

antinodes vibrate and are the opposite of nodes which are stationary.

Some parts of the pizza are hot while others are still cold. Because the antinodes of a standing wave shake very quickly, causing the hot spots on the pizza to appear.

The fact that there are locations along the medium that appear to be standing still is a feature of every standing wave pattern.

The term "node" refers to these sites, which are also known as "points of no displacement." Other sites along the medium are subjected to vibrations with substantial positive and negative displacements.

During each vibrational cycle of the standing wave, these are the locations that experience the most displacement. These points are termed "antinodes" because they are the polar opposites of nodes.

The antinodes of a standing wave shake very quickly, causing the hot spots on the pizza to appear. The wave isn't moving very much at the nodes, therefore those areas of the pizza stay cold."

Hence some parts of the pizza are hot while others are still cold.

Answer:

4. Force = 178.6 Newton.

5. Acceleration = 2.28 m/s².

6. Force = 178.6 Newton.

Explanation:

4. Given the following data;

Acceleration = 3.8 m/s²

Mass = 47kg

Force = mass * acceleration

Force = 47 * 3.8

Force = 178.6 Newton.

5. Given the following data;

Force = 785N

Mass = 345kg

Acceleration = force/mass

Acceleration = 785/345

Acceleration = 2.28 m/s²

6. Given the following data;

Acceleration = 6m/s²

Force = 32N

Mass =force/acceleration

Mass = 32/6

Mass = 5.33 kilograms

Explanation:

The increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

Thermal expansion is the property of the matter to change its shape, size, length, volume, density etc with change in the temperature.

The thermal expansion can be calculate as,

[tex]\Delta L=aL\Delta T[/tex]

Here, [tex]L[/tex] is the original length, [tex]\Delta T[/tex] is the change in the temperature and [tex]a[/tex] is the coefficient of the expansion.

Given information-

The change in the length of the aluminum mater-stick is 1.00 mm.

Let the initial size of the aluminium mater-stick is 1.00 m or 1000 mm . The thermal expansion coefficient of aluminium is [tex](2.4\times10^{-5})[/tex] per unit Kelvin.

Put the values in the above formula as,

[tex]1=(2.4\times10^{-5})\times 1000\times\Delta T[/tex]

Solve for temperature as,

[tex]\Delta T=\dfrac{1}{(2.4\times10^{-5})\times 1000} \\\Delta T=42K[/tex]

Hence the increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

Answer:

18kW

Explanation:

very LED bulb has a power rating in terms of Watt-hour. It gives the power consumption per hour. For e.g. a 100W light bulb consumes 100W of electricity per hour. If left 'on' for 10 hours, a 100W light bulb costs 1kW and 1 unit of electricity is burned. Because 1 unit = 1 Kw of electricity.

I calculated my electricity consumption in 1 hour with LED Bulb as follows-

LED Bulbs power rating- 15 watt

quantity- 1

No. of hours a day – 12

Wattage in 1 hour – 12(time) x 15(load) x 1(quantity) = 180W = .18kW

So consumption units of power with a LED Bulb consume in 1 hour= .18 Units (because 1 KW = 1 unit)

Answer:

60

Explanation:

Answer:

The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ. The wave frequency and the period are inversely related to one another.

Explanation:

T = 1 / f is the formula to calculate the period of a wave.

The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds.

The calculation of period of wave is:

The formula for period is T = 1 / f ,

where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.

To get period from frequency, first convert frequency from Hertz to 1/s.

Period refers to the time for something to happen and is measured in seconds/cycle.

In this case, there are 11 seconds per 33 vibrational cycles.

Thus the period is (11 s) / (33 cycles) = 0.33 seconds.

Therefore,

T = 1 / f is the formula to calculate the period of a wave.

Answer:

gravity

Explanation:

Technically it would be mass or speed because it depends on ow big or small it is, but if you break it down it will be due to gravity as it gets stronger

Choice-B is a relevant statement, although we can't see enough of the picture to actually know what's going on.

A good example of this scenario is our own moon.  Because of the Sun's  gravitational influence, the Moon's orbit around the Earth is not a circle or an ellipse.
