Mass over volume is the answer
D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289
Answer:
The package will be directly below the location of the plane.
Explanation:
Look up projectile motion for more information. The horizontal speed of the package is separate from the vertical speed of the package. The vertical speed of the falling package will be based on the rate of acceleration and the height of the package when dropped. The horizontal speed of the package will be the same as the plane so the package will remain directly below the plane the entire time until the package hits the ground.
Answer:
So then we will have that the 3 working together will complete 1 job in approximately 1.429 hours for this case.
Explanation:
If we want to express the situation in math terms and find the number of hours that takes to complete 1 job with the 3 at the same time, we can do this.
For this case we have the following rates:
And we know that working together the rate would be the addition of the rates like this:
And if we divide the numerator and denominator by 7 we got:
So then we will have that the 3 working together will complete 1 job in approximately 1.429 hours for this case.
The correct answer is "decrease":
<span>A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will INCREASE the wavelength.
Let's see why. The basic relationship between frequency and wavelength of a wave is
</span>
<span>where
v is the speed of the wave
f its frequency
</span>
its wavelength
<span>
We can see from this equation that, if the frequency is increased, if the speed of the wave does not change (and this is the case), then the wavelength of the wave must decrease, since the ratio </span>
becomes smaller.
