Answer:

A nuclear to thermal and radiant

Explanation:

Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.

In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.

The nuclei obtained from nuclear fission are different and lighter than the initial nucleus. The excess energy that emerges from nuclear fission is what is known as nuclear energy.

Nuclear fission produces energy in the form of heat and other radiations releasing (ie thermal and radiation in general), in turn, other neutrons. Each generated neutron collides with the other nuclei created, producing a chain reaction.

Nuclear fission can be used for power generation through a nuclear reactor. A nuclear reactor is a facility that generates self-sustained and controlled nuclear reactions, and uses the energy released from the fission of atoms.

For example, one of the first applications of nuclear fissions used uranium atoms to produce electricity.

The correct answer is A. I just took the test.

"nuclear to thermal and radiant"

Trust me y'all, this is the correct answer. I thought it was C but it's actually A. :)

Some car manufacturers claim that their vehicles could climb a slope of 42 ∘. For this to be possible, what must be the minimum

Paladinen [302]

Answer:

D. 0.9

Explanation:

Calculating minimum coefficient of static friction, we first resolve the forces (normal and frictional) acting on the vehicle at an angle to the horizontal into their x and y components. After this, we can now substitute the values of x and y components into equation of static friction. Diagrammatic illustration is attached.

Resolving into x component:

∑ $F_{x} = F_{s} - mgsin\alpha =0$

$F_{s} = mgsin\alpha$ ------(1)

Resolving into y component:

∑ $F_{y} = F_{n} - mgcos\alpha =0$

$F_{n} = mgcos\alpha$ ------(2)

Static frictional force, $F_{s} \leq$ μ $F_{n}$ ------(3)

substituting $F_{s}$ from equation (1) and $F_{n}$ from equation (2) into equation (3)

$mgsin\alpha \leq$ μ $mgcos\alpha$

$sin\alpha \leq$ μ $cos\alpha$

μ $\geq \frac {sin\alpha}{cos\alpha}$

μ $\geq tan\alpha$

The angle the vehicles make with the horizontal α = 42°

μ ≥ tan 42°

μ ≥ 0.9

A violinist tuning her violin plays her A-string while sounding a tuning fork at A 415 Hz, and hears 5 beats per second. When sh

frutty [35]

Answer:410 Hz

Explanation:

It is given that frequency of tuning fork is 415 Hz and hears a beat of 5 beat per second

so untuned frequency must be either 410 Hz or 420 Hz because beat frequency is the difference in frequency of two notes.

When she tightens the string the beat frequency decrease

and velocity $v=\nu \lambda$

where $\nu =frequency$

$\lambda =wavelength$

$v=velocity$

$v=\sqrt{\frac{T}{\mu }}$

where T=tension

it T increase v also increases and from 1 st equation frequency is also increasing therefore untuned frequency must be 410 Hz because beat frequency is decreasing.
