Answer:

There are different answers to that, like if you read a passage or something.

Explanation:

These days many people do not get exercise. A lot of jobs are now done indoors and do not require any physical activities. Technology is becoming more advanced and many people prefer using machines to do the heaving lifting.

There are a lot of fast-food restaurants and this is where a lot of people in the US choose to eat. The food is cheap and easy to pick up. This food is convenient for people on the go. The food is not healthy and it causes weight gain.

In the US, many young children find it cool to smoke. Smoking decreases the body's strength and it causes a decrease in physical health, causing people to gain weight.

Everyone has a phone these days, if not some kind of electronic device to chat with people or play games. Over time, playing on electronic devices replaces doing physical activities.

What was the measurement of the wavelength and amplitude respectively?

SpyIntel [72]

<h3>Answer</h3>

option C)

The wavelength has a length between 7.0 cm and 8.0 cm and the amplitude lies between 1.0 cm and 2.0 cm.

<h3>Explanation</h3><h2>1)</h2>

The amplitude of a wave is the height of a wave as measured from the highest point on the wave, peak, to the rest point or from the lowest point on the wave, trough, to the rest point.

By looking at the image

rest point is at 5cm and crest is at 3.3 cm (y-axis)

so amplitude = 5 - 3.3

= 1.7 cm (approximately)

Wavelength refers to the length of a wave from one peak to the next.

one crest is at 2cm and the other crest is at 10cm (x-axis)

so wavelength = 10 - 2

= 8 cm (approximately)

What would the weight of an astronaut be on Neptune if his mass is 68 kg and acceleration of gravity of Neptune is 11.15 m/s^2?

Dima020 [189]

Weight = Mass of object * Gravity of experimented place
Here, m = 68 Kg
g' = 11.15 m/s²

Substitute their values,
w = 68 * 11.15
w = 758.2 N

In short, Your Answer would be 758.2 Newtons

Hope this helps!

A bug on the surface of a pond is observed to move up and down a total vertical distance of 6.5 cm , from the lowest to the high

m_a_m_a [10]

Answer:

factor that bug maximum KE change is 0.52284

Explanation:

given data

vertical distance = 6.5 cm

ripples decrease to = 4.7 cm

solution

We apply here formula for the KE of particle that executes the simple harmonic motion that is express as

KE = (0.5) × m × A² × ω² .................1

and kinetic energy is directly proportional to square of the amplitude.

$\frac{KE2}{KE1} = \frac{A2^2}{A1^2}$ .............2

$\frac{KE2}{KE1} = \frac{4.7^2}{6.5^2}$

$\frac{KE2}{KE1}$ = 0.52284

so factor that bug maximum KE change is 0.52284
