Answer:

False

Explanation:

This statement is False.

The atom is made up of nucleus in which there are neutrons and protons and electrons which are revolving around the atom's nucleus.

nuclear energy is basically energy the source of which is nucleus of the atom. there are two methods by which nuclear energy is produces.

1) Nuclear fission

2) nuclear fusion

In nuclear fission, the neutron is bombarded on the nucleus of an atom of an element. It splits and produces a daughter nucleus, neutrons and huge amount of energy

In nuclear fusion, two nuclei of the atoms fuse and produce huge amount of energy.

In both of above mentioned cases, there is neither any role of electrons to produce energy nor in storing nuclear energy.

So, the given statement is wrong

Key words: Nucleus, Nuclear energy, electron, Nuclear fission, Nuclear fusion, neutrons, atom

False. The nuclear energy is found within the nucleus. Electrons are located outside the nucleus.

What is the formula to calculate the readings on an ammeter?

Cloud [144]

If the voltage and the resistance are known within the circuit, then you can use the formula:

Current = Voltage / Resistance

If you know the amount of charge going past a certain location in a certain amount of time, then you can find the current using:

Current = charge / time

A wave is traveling through a medium ad it travels it displaces particles of matter in the same direction as the wave is traveli

Tamiku [17]

I think it's longitudinal wave because the particles move parallel to the direction that the wave is traveling.

When the Glen Canyon hydroelectric power plant in Arizona is running at capacity, 690 m3 of water flows through the dam each sec

igomit [66]

Answer:

The maximum electric power output is $P_{max} =1.339*10^{9} \ W$

Explanation:

From the question we are told that

The capacity of the hydroelectric plant is $\frac{V}{t} = 690 \ m^3 /s$

The level at which water is been released is $h = 220 \ m$

The efficiency is $\eta =$ 0.90

The electric power output is mathematically represented as

$P = \frac{PE_l - PE _o}{t}$

Where $PE_l$ is the potential energy at level h which is mathematically evaluated as

$PE_l = mgh$

and $PE_o$ is the potential energy at ground level which is mathematically evaluated as

$PE_o = mg(0)$

$PE_o = 0$

$P = \frac{mgh}{t}$

here $m = V * \rho$

where V is volume and $\rho$ is density of water whose value is $\rho = 1000 kg/m^3$

$P = \frac{(\rho * V) * gh}{t}$

$P = \frac{V}{t} * gh \rho$

substituting values

$P =690 * 9.8 * 220 * 1000$

$P =1.488*10^{9} \ W$

The maximum possible electric power output is

$P_{max} = P * \eta$

substituting values

$P_{max} =1.488*10^{9} * 0.90$

$P_{max} =1.339*10^{9} \ W$

in a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of frequency 105.0 mhz in opposite direction

Romashka [77]

As a result, the hollow is 10.90 meters long and the distance between the nodal planes is 1.36 meters.

<h3>Explain electromagnetic waves.</h3>

The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves.

By definition, we understand that the frequency equals,

f = c/λ

where,

λ = wavelength

c= Speed of light

λ = 2L / n

While the wavelength is equal to,

Where,

L = Length

n = Number of antinodes/nodes

PART A) We know that the first component's wavelength is 110 MHz, so

λ = c/ f

λ = 3*10^8 / 11*10^6

λ = 1.36m

Therefore the distance between the nodal planes is 1.36m

PART B) For this part we need to find the Length through the number of nodes (8) and the wavelength, that is,

λ` = 2l /n

L = 8*2.72/ 2

L = 10.90m

Therefore the length of the cavity is 10.90m.
