Answer:

C.  changing nuclear energy to radiant energy

Explanation:

Nuclear energy takes atoms in their potential state, split them (fission) or fuse them (fusion)  creating chain reactions of radiant energy.  Most nuclear electrical power plants use fission, radiant energy heats water making steam to spin turbines.

Or think of the atom bomb.  Definitely potential energy until the fuse starts detonation and chain reactions.  The radiant kinetic energy and shock waves were horrendous.

A box sliding on a horizontal frictionless surface encounters a spring attached to a rigid wall and compresses the spring by a c
GaryK [48]

Answer:

a) K = 49.5 J  b) k = 1378 N / m c) ΔE = 34 J  d)  μ = 0.399

Explanation:

For this exercise we will use the concepts of energy

a) The initial kinetic energy is

    K = ½ m v²

    K = ½ 3.96 5²

    K = 49.5 J

b) let's use energy conservation

    Em₀ = K = ½ m v²

    Em_{f} = Ke = ½ k x²

    Em₀ =  Em_{f}

    ½ m v² = ½ k x²

    k = m v² / x²

    k = 3.96 5² / 0.268²

    k = 1378 N / m

c) Let's calculate the final energy of the spring

     Em_{f} = Ke = ½ k x²

    Em_{f} = ½ 1378 0.15²

     Em_{f} = 15.5 J

The initial energy is the kinetics of the block

    Em₀ = 49.5 J

The lost energy is the difference with the initial

    ΔE =  Em_{f} - Em₀

    ΔE = 15.5 - 49.5

    ΔE = - 34 J

the negative sign means that the energy dissipates

d) For this part we use the concept of work

   W = F d cos θ = ΔK

In this case the force is the friction force that always opposes displacement, so the angle 180 ° and cos 180 = -1

    W = -fr d = ΔK

The force of friction is

   fr = μ N

With Newton's second law

    N-w = 0

    N = W = mg

Let's calculate

   -μ mg d = Kf -K₀o

    μ = K₀ / mgd

    μ = 49.5 / (3.96  9.8  3.20)

    μ = 0.399

a football player starts from rest and speeds up to a final velocity of 12 m/s. the speeding up takes a total of 6 seconds. what
gizmo_the_mogwai [7]

Answer:

2 m/s²

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 0 m/s

Final velocity (v) = 12 m/s

Time (t) = 6 s

Acceleration (a) =?

The acceleration of the player can be obtained as follow:

v = u + at

12 = 0 + (a × 6)

12 = 6a

Divide both side by 6

a = 12 / 6

a = 2 m/s²

Thus, the acceleration of the player is 2 m/s²

emmainna [20.7K]

Continuous signals are characterized as analog signals that are broken up into binary code are characterized as digital.

An am/fm radio is a good example of analog technology. A smart phone is a good example of digital technology.

<h3>What is a Digital technology?</h3>

These are devices that generate, store or process data while analog is a continuous signal that represents physical measurements.

The examples of analog and digital technology are mentioned above and is the most appropriate choice.
