A cart with an unknown mass is at rest on one side of a track. A student must find the mass of the cart by using newton’s second law. The student attaches a force probe to the cart and pulls it while keeping the force constant. A motion detector rests on the opposite end of the track to record the acceleration of the cart as it is pulled. The student uses the measured force and acceleration values and determines that the cart’s mass is 0. 4kg. When placed on a balance, the cart’s mass is found to be 0. 5kg. Which of the following could explain the difference in mass?.

Answers

Answer 1

An 85-foot wire is tied from the top of a utility pole to the top of the building as shown below. Find d, the distance from the pole to the building.

Answers

The distance from the pole to the building is 79 feet

The relationship between the utility pole and the 85-foot wire, can be adjusted to fit in the description of a right-angled triangle.

So, the distance (d) can be calculated using the following sine function.

[tex]\sin(68) = \frac{d}{85}[/tex]

Multiply both sides of the equation by 85

[tex]85 \times \sin(68) = \frac{d}{85} \times 85[/tex]

Cancel out the common factors

[tex]85 \times \sin(68) = d[/tex]

Evaluate sin(68)

[tex]85 \times 0.9272 = d[/tex]

Evaluate the product

[tex]78.812 = d[/tex]

Approximate

[tex]79= d[/tex]

Rewrite the equation

[tex]d = 79[/tex]

Hence, the distance from the pole to the building is 79 feet

Which image do you think best illustrates the tragedy of the fire? why? give at least three reasons for your choice in your response.

Answers

9-13 and 17

Pictures 9-13 actually show dead people, who died trying to escape the fire. These were people who had lives, families, etc. who never knew that an ordinary work day would turn tragic. The sheer number of people seen truly shows how horrific of an event this was, with their bodies being broken and lifeless.

17 shows the aftermath of the fire. What was once a busy, bustling workplace full of life was now lonely and deserted, with the ashes of equipment, clothing, and crushed memories. The scorched-black room and messy area really give off that "neglected and forgotten" feel. Even the officer contributes to the empty feel of the room, as he's the only one seen there, all alone.

Pictures 9 through 13 show actual deceased victims who perished while attempting to flee the fire. These were folks with families, lives, and other responsibilities who had no idea that a routine workday would end tragically.

What is Fire?

The observable result of the combustion process, a unique kind of chemical reaction, is fire. It happens when some kind of fuel and atmospheric oxygen are combined. The end result of the chemical reaction is entirely distinct from the initial component.

The heat from the heat causes some of the cellulose material that makes up the wood to break down when the wood reaches about 300 degrees Fahrenheit (150 degrees Celsius).

The molecules of the complex disintegrate at a temperature of roughly 500 degrees F (260 degrees C) for wood, at which point the atoms recombine with oxygen to generate water, carbon dioxide, and other products. They burn, in other terms.

A spring with a spring constant of 150 n/m has an equilibrium length of 8. 0 cm. What is the change in spring potential energy when the spring is stretched from a length of 11. 0 cm to 14. 0 cm?.

Answers

When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores

1/2 (150 N/m) (0.030 m)² = 0.0675 J

of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores

1/2 (150 N/m) (0.060 m)² = 0.27 J

Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J

You wish to earn a return of 13% on each of two stocks, x and y. Stock x is expected to pay a dividend of $3 in the upcoming year while stock y is expected to pay a dividend of $4 in the upcoming year. The expected growth rate of dividends for both stocks is 7%. The intrinsic value of stock x.

Answers

Based on the information given, the intrinsic value of stock x will be less than the intrinsic value of stock Y.

Based on the information given above, the intrinsic value of Stock X will be calculated thus:

D1 = Dividend in next year = $3

g = growth rate = 7%

r = = 13%

Therefore, intrinsic value of Stock X will be:

= D1 / (r-g)

= 3 / (13% - 7%)

= 3/6%

= 3 / 0.06

= $50

Therefore, the intrinsic value of stock X is $50.

Intrinsic value of Stock Y will be calculated thus:

D1 = $4

g = 7%

r = 13%

Intrinsic value of Stock Y will be:

= D1 / (r-g)

= 4 / (13% - 7%)

= 4/6%

= 4 / 0.06  

= 66.67

Intrinsic value of Stock Y is $66.67

Therefore, the intrinsic value of Stock X will be less than the intrinsic value of Stock Y.
