topjm [15]3 years ago
5 0

Answer:

Efficiency of the machine = 75%

Explanation:

Given:

Input work = 8,000 J

Output work = 6,000 J

Find:

Efficiency of the machine

Computation:

Efficiency of the machine = [Output work / Input work]100

Efficiency of the machine = [6,000 / 8,000]100

Efficiency of the machine = 75%

An object starts from rest at the origin and moves along the x axis with a constant
Alika [10]

Answer:

6.9m/s

Explanation:

Given parameters:

Acceleration of the object  = 4m/s²

Distance = from x; 2m to x; 8m

Unknown:

Average velocity  = ?

Solution:

From the given parameters, we use the right motion equation to solve the problem.

   v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

 S is the distance covered

 Distance  = 8m - 2m  = 6m

 Initial velocity  = 0m/s

The final velocity gives us the average velocity in this problem;

       v² = 0² + (2 x 4 x 6) = 48

      v = √48  = 6.9m/s

The type of chemical bond that involves the transfer of electrons between atoms is a(n) bond.
GaryK [48]
<h3>Answer;</h3>

<em>-Ionic bond</em>

<h3>Explanation;</h3>
  • <u>Ionic bond</u> is a type of bonds that results from transfers of electrons from one atom to another.  This types of bond is formed between metals and non metals.
  • Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion.
  • For instance; between sodium and chlorine element; sodium donates a single electron to attain a stable configuration while chlorine gains an electron to achieve stable configuration, thus forming an ionic compound sodium chloride.

2(A + B)
SCORPION-xisa [38]

Answer:

θ = cos^(-1) (-A/B)

Explanation:

The image of the reauktant forces A & B are missing, so i have attached it.

Now, from the attached image, we will see that;

Angle between A and B is θ

Also;

A = Bcos(180° − θ)

Now, in trigonometry, we know that;

cos(180° − θ) = -cosθ

Thus;

A = -Bcosθ

cosθ = -A/B

Thus;

θ = cos^(-1) (-A/B)
