In one eight-hour workday, a forklift operator at a particular distribution warehouse lifts a total of 100,000 N of boxes. Each

box must be lifted to a height of 1.5 m and carried an average of 10 m to the shipping dock. What is the net work done against gravity?

Answer:

150000 J

Explanation:

Only the work that is used to lift the boxes up by 1.5 m is counted against gravity. The work that is used to move 10m to the dock is not.

This work done to lift up by 1.5m is the product of force lifted F = 100 000 N and the vertical distance in height h = 1.5m

W = F*h = 100000*1.5 = 150000 J

A gas had a initial volume of 168 cm at a temperature of 255 k and a pressure of 1.6 atm the pressure of the gas decreased to 1.
Mademuasel [1]

P₁V₁ / T₁ = P₂V₂ / T₂

1.6 × 168 /255 = 1.3 × V₂ / 285

V₂ = 1.6 × 168 × 285 / (1.3 × 255)

V₂ = 231.095

The final volume = 231 cm³

What is Stefan Boltzmann's law???<br> Need explaination
sukhopar [10]

Answer:

The Stefan–Boltzmann law, also known as Stefan's law, states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black-body irradiance, energy flux density, radiant flux, or the emissive power), j*, is directly proportional to the fourth power of the black body's

A partially discharged car battery can be modeled as a 9.0-V emf in series with an internal resistance of 0.18 Ω . Jumper cables
Bad White [126]

Answer:

The answer is <em>15A</em>

Explanation:

Terminal of like polarity are connected with jumpers of negligible resistance

Kirchoff's voltage law gives

E1 -E2 - IR1 - IR2 = 0

I(R1 + R20 = E1 -E2

I= 12 -9/ 0.18 + O.2 = 15A OF CURRENT WILL FLOW THROUGH DISCHARGED BATTERY.

This question is incomplete; here is the complete question:

Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he measures the frequency as 3 hertz, which statement about the wave is accurate?

A. The wave has traveled 32.4 cm in 3 seconds.

B. The wave has traveled 32.4 cm in 9 seconds.

C. The wave has traveled 97.2 cm in 3 seconds.

D. The wave has traveled 97.2 cm in 1 second.

The answer to this question is D. The wave has traveled 97.2 cm in 1 second.

Explanation:

The frequency of a wave, which is in this case 3 hertz, represents the number of waves that go through a point during 1 second. According to this, if the frequency of the wave is 3 hertz this means in 1 second there were 3 waves. Moreover, if you multiply the wavelength (32.4cm) by the frequency (3) you will know the distance the wave traveled in 1 second: 32.4 x 3 =  97.2 cm. This makes option D the correct one as the distance in 1 second was 97.2 cm.

How does evaporation happen on a stove<br> (dont mind the subject btw)
Shtirlitz [24]

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆

Answer: Evaporation happens by heat being transferred to the pot, then the pot transfering the heat to the water, which caused the water to vibrate more, eventually turning it into water vapor, which is how evaporation happens on the stove.

Explanation:

I hope this helped!
