A 70 N force pulls a box straight up 5 m above the ground. How much work is done on the box?

Chemistry
1 answer:
Bingel [31]3 years ago
5 0

D. 350 J

Explanation:

Given parameters:

Force of pull = 70N

Distance = 5m

Unknown:

Workdone on the box = ?

Solution:

Workdone is defined as the force applied on a body to move it through a distance.

   Work done = Force x distance moved

   Work done =  5 x 70 = 350J

  • Left to Right<u> </u>

<u>Chemistry</u>

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 2Al₂O₃ → 4Al + 3O₂

[Given] 20 mol Al₂O₃

<u>Step 2: Identify Conversions</u>

[RxN] 2 mol Al₂O₃ → 4 mol Al

<u>Step 3: Stoich</u>

  1. [DA] Set up:                                                                                                     \displaystyle 20 \ mol \ Al_2O_3(\frac{4 \ mol \ Al}{2 \ mol \ Al_2O_3})
  2. [DA] Multiply/Divide [Cancel out units]:                                                         \displaystyle 40 \ mol \ Al

<u>Step 4:Check</u>

<em>Follow sig fig rules and round. We are given 1 sig fig.</em>

Since our final answer already has 1 sig fig, there is no need to round.

Laser fusion Group of answer choices uses chemical reactions to produce energy uses nuclear reactions to produce energy implodes
KonstantinChe [14]

Answer:

Uses nuclear reactions to produce energy

Implodes a fuel pellet

Explanation:

Laser fusion is a method of initiating nuclear fusion reactions through heating, and compressing fuel pellets containing deuterium and tritium using high energy density laser beams. Lase fusion is also known as inertial confinement fusion and the energy produced by the process is known as Laser Inertial Fusion Energy, LIFE.

During the process of laser fusion, small pellets of deuterium-tritium (DT) isotopes mixture are fed into a blast chamber where they are compressed to high densities using a number of amplified laser beams in the chamber.

The high energy density of the beams as well as the heat produced due to compression, induces the thermonuclear explosion ignition resulting in the production of high energetic products such as charged particles, x-rays and neutrons. The energy produced is absorbed and stored as heat in a blanket that is then used in a steam thermal cycle to generate electrical power.

There are two methods of compression of the DT pellet: direct and indirect-drive laser fusions.

However, there are a number of limitations to energy production by this process. One limitation is that the process is extremely inefficient in energy energy production. Also, the heat produced by the flashtubes results innthe deformation of the laser glass.

Which of the following are functions of the ears?
Advocard [28]

The functions of the ears are:

I. Hearing by collecting and processing sound waves

II. Keeping our balance when we turn or bend over; option A

<h3>What is the function of the ear?</h3>

The ear is one of the five sense organs in the body.

The sense organs are the organs which receive external stimulus and send it to the brain for processing and response.

The other sense organs are:

  • the eye
  • the nose
  • the skin
  • the tongue

The functions of the ear are for hearing and for balance.

In conclusion, the sense organs function to receive stimulus and send them to the brain.
