Answer:
C. hyperbola
Explanation:
From Boyle's law:
PV = k, where k is a constant
Solving for P:
P = k / V
At first glance, this equation doesn't fit any of the options. But when you graph it, you can see that it's actually a <em>rotated</em> hyperbola.
Answer:
579600J
Explanation:
Given parameters:
Height of the building = 828m
Weight of the man = 700N
Unknown:
Work done by the man = ?
Solution:
The work done by the man is the same as the potential energy expended.
Work done:
Work done = Weight x height = 700 x 828
Work done = 579600J
If an element has a charge of +1, there is 1 more proton than electrons.
A proton has a charge of +1
A neutron has a charge of 0
A electron has a charge of -1.
For there to be a charge of 0, there would be the same amount of charges for both proton and neutron. To get a charge of 1, you will need 1 more proton.
hope this helps
Answer:
The frequency increases with a shorter horn <em>(Option B)</em>.
Explanation:
The length of the horn determines the distance along which the wave travels; simply called the wavelength. Therefore, a short horn tube will produce a short wavelength and vice versa.
Sound waves have various characteristics that define pitches in musical instruments and these characteristics are interdependent on each other.
in this case, the frequency and the frequency and the wavelength are related.
The relationship between the wavelength and its frequency is given as:
<em> </em><em>c = f λ </em><em> </em>
<em>where 'c' is the speed of sound through the instrument; 'f ' is the frequency and 'λ' is the wavelength.</em>
Let's assume that the speed at which the musician blows air into the mouthpiece remains constant, an increase in wavelength will cause a decrease in frequency. Conversely, as the tube of the horn becomes shorter the frequency increases.
