A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the value of work being done on the object?

Answers

Answer 1
Answer: The total work done is 957.56 joules. This is calculated as work is equal to 25N time 50 meters time cosine 40 degrees.
Answer 2
Answer:

Answer:

Work being done on the object = 766.04J

Explanation:

Work done by a force  is calculated by finding dot product of force and displacement.

            W = F . s

             F = 25 N

              s = 50 m

               θ = 40.0°

W = F . s = Fs cosθ = 25 x 40 x cos 40 = 766.04J

Work being done on the object = 766.04J

What are Underground Storage Tank Systems?

Underground Storage Tank systems are tanks along with the underground piping that has at least 10% of their total volume underground.

Some of the storage tanks that are exempt from the federal regulations on USTs are;

  • Farm and residential tanks of 1,100 gallons or less capacity holding motor fuel used for noncommercial purposes.
  • Tanks storing heating oil used on the premises where it is stored.
  • Tanks of 110 gallons or less capacity.

Final answer:

The federal UST regulations typically do not cover tanks that store heating oil used on site, tanks that hold less than 200 gallons, and farm and residential tanks that hold 2,000 gallons or less of motor fuel for noncommercial uses.

Explanation:

The question pertains to certain types of storage tanks that are exempt from federal regulations called USTs (Underground Storage Tanks). These tanks are used to store regulated substances, typically petroleum and hazardous substance. However, not all tanks fall under these regulations. For instance, tanks that store heating oil used on the premises where it is stored, tanks that hold less than 200 gallons, and farm and residential tanks that hold 2,000 gallons or less of motor fuel for noncommercial uses, are not governed by these federal UST regulations. Hence, the correct answer is D) all of these.

A cat jumps 1m forward, then crawls 0.2m backwards. What is the displacement of the cat?

Answers

I think its 0.8m because 1+(-0.2)=0.8
Displacement refers to how far out of place an object is. So if the cat jumps a meter forward, than crawls back .2 meters, the cat is .8 meters out of place

PLEASE HELP!! Use the information below to solve this problem: A note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, what pitch is this note? speed of sound in air: 343 m/s

A. 440.00 Hz
B. 493.88 Hz
C. 523.25 Hz
D. 587.33 Hz
E. 659.26 Hz
F. 698.46 Hz
G. 783.99 Hz​

Answers

Answer:

C

Explanation:

Given that a note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, the pitch of the note is the same as the frequency.

Sound Velocity = product of frequency and wavelength.

Substitute wave speed and wavelength into the formula

343 = f × 0.65551

Make f the subject of formula

F = 343 / 0.65551

F = 523.58 Henz

Therefore, the pitch of the note is 523.52 Hz approximately

The correct answer is option C
