A worker pushes a 7 kg shipping box along a roller track. Assume friction is small enough to be ignored because of the rollers.

The worker's push is 25 N directed down and to the right at an angle of 20°.
(a) Determine the horizontal component of the worker's push.
(b) Write a net force equation for the horizontal forces on the box.

Answer:

a) Fₓ = 23.5 N

b) Net force = Fₓ

Explanation:

An illustration of the query as mentioned is included with this answer.

According to the provided image, the forces on the box include its weight, the normal force from the surface beneath it, the applied force by the worker, and the frictional force acting against the box's motion (which is considered negligible and essentially 0)

a) Based on the diagram, the horizontal force component can be calculated as

Fₓ = 25 cos 20° = 23.49 N = 25 N

b) Referring again to the attached diagram, performing a force analysis on the box in the horizontal direction allows us to conclude

Net force = Fₓ - Frictional force

Since the frictional force is 0 N

Net force = Fₓ

Hope this Helps!!!

A particular brand of gasoline has a density of 0.737 g/mLg/mL at 25 ∘C∘C. How many grams of this gasoline would fill a 14.9 gal
Yuliya22 [3333]

Answer:

The answer to your inquiry is Mass = 41230.7 g or 41.23 kg.

Explanation:

Data

Density = 0.737 g/ml

Mass = ?

Volume = 14.9 gal

1 gal = 3.78 l

Process

1.- Convert gallons to liters

1 gal ---------------- 3.78 l

14.9 gal ------------- x

x = 56.44 l

2.- Convert liters to milliliters

1 l ------------------- 1000 ml

56.44 l --------------- x

x = (56.44 x 1000) / 1

x = 56444 ml

3.- Calculate the mass

Formula

Density = \frac{mass}{volume}

Solving for mass

Mass = density x volume

Substituting values

Mass = 0.737 x 56444

Result

Mass = 41230.7 g or 41.23 kg.

Jade and her roommate Jari commute to work each morning, traveling west on I-10. One morning Jade left for work at 6:45 A.M., bu
Maru [3345]

Answer:

Jari

Explanation:

To determine who is traveling faster, we need to evaluate their gradients. A steeper slope indicates a higher speed.

For Jari's path, starting point is (0, 0) and (6, 7) is another point.

The gradient is the difference in y divided by the difference in x:

Change in y=7-0=7

Change in x=6-0=6

Thus, the slope equals 7/6.

For Jade, her first point is (0, 10) and another is (6, 16).

Change in y=16-10=6

Change in x=6-0=6

Thus, the slope equals 6/6=1.

It's evident that 7/6 exceeds 6/6 or 1, proving Jari is quicker than Jade.

Albert uses as his unit of length (for walking to visit his neighbors or plowing his fields) the albert (a), the distance albert
Yuliya22 [3333]

To tackle this question, we know the following:

1 Albert equals 88 meters.

1 A = 88 m.

Initially, we square both sides of the equation:

(1 A)^2 = (88 m)^2

1 A^2 = 7,744 m^2

<span>Since 1 acre equals 4,050 m^2, let’s divide both sides by 7,744 to find out how many acres match this value:</span>

1 A^2 / 7,744 = 7,744 m^2 / 7,744

(1 / 7,744) A^2 = 1 m^2

Then multiply both sides by 4,050.

(4050 / 7744) A^2 = 4050 m^2

0.523 A^2 = 4050 m^2

<span>Thus, one acre is approximately 0.52 square alberts.</span>
