In which situation is the maximum possible work done?

Physics
1 answer:
ExtremeBDS [4]3 years ago
3 0

Answer:

Answer is A.

Explanation:

Remember the equation for work:

W = F d cos θ

Math explanation: When θ = 0, cos θ = 1, so Fd is a maximum. For any other value of θ up to 90 degrees, cos θ < 1 so Fd will be smaller. For θ = 180, you're pushing away from the direction of displacement so you're actually doing negative work.

Intuitive explanation: you have the most success pushing an object when you apply the force directly against it compared to if the force was directed at an angle.

The distance from earth to a NASA satellite traveling through the solar system is 6.0 × 109m. A command is sent to the satellite
alexandr1967 [171]

Answer:

the signal it takes 40 s to get the answer

Explanation:

As the satellite is in space the speed of radiation (waves9 is the speed of light in a vacuum, which is constant 3. 108 m / s, so we can use the uniform motion ratios to find the time.

    v = d / t

    t = d / v

    t = 6.0 109 / 3. 108

    t = 2 101 s

    t = 20 s

This is the time it takes to get the signal from the earth to the satellite and it takes the same time to return, so since they send the signal it takes 40 s to get the answer

Michael is biking on a trail and is accelerating at a rate of 1.2 m/s/s for 15 seconds. He began this part of his ride with a ve
Serhud [2]

Answer:

Michael's final velocity is 19.62 m/s.    

Explanation:            

We can find the final velocity of Michael by using the following kinematic equation:

v_{f} = v_{0} + at   (1)    

Where:

v_{f}: is the final velocity =?

v_{0}: is the initial velocity = 1.62 m/s

a: is the acceleration = 1.2 m/s²

t: is the time = 15 s

By entering the above values into equation (1) we have:

v_{f} = 1.62 m/s + 1.2 m/s^{2}*15 s

v_{f} = 19.62 m/s

Therefore, Michael's final velocity is 19.62 m/s.

I hope it helps you!

A student blows in a tube with one closed in that is 0.49 m long. If the frequency of the sound is 358 Hz what is the speed wave
BaLLatris [955]

Answer:175.42m/s

Explanation:

Wavelength=0.49m

Frequency=358Hz

Velocity=frequency x wavelength

Velocity=358x0.49

Velocity=175.42m/s

Describe the different types of objects found in the Universe
Tema [17]
There are asteroids, which are rocks that fly through the space, and meteors which are pretty much the same. The only difference is their sizes. There are also planets, big and small. The moon, the dwarf planet Pluto, and many more. There are probably thousands of other planets that we haven't quite yet discovered. Soon we will though. There are also billions of stars, such as the sun, and some others we don't have names for that form constellations.
Hope this helped!!
