15) C. The amount of each element that begins....
Alpha - <span>The radiation particle is positively charged.
</span>Beta - <span>The radiation particle is negatively charged.
</span>Gamma - The radiation is a wave, not a particle.
The answer is C. Neutron star.
Answer:
62.1 ft
Explanation:
We know that
hence 240 gpm will be
From the formula of obtaining efficiency
and making
the subject we have
where Q is flow rate,
is specific weight of water,
is actual head rise and
is the power input to the compressor
Substituting 0.62 for
, 6hp for
,
for
and
for Q then
Therefore, actual head rise of the water being pumped is 62.1 ft
To solve this problem it is necessary to apply the concepts related to Ohm's Law to find the voltage in the case of direct current. While for the Alternate current we use the concept of RMS voltage.
PART A) In the case of DC we have to,
V=IR
Where,
I = Current
R = Resistance
Where the current is 60mA y the resistance is
, then the potential would be


In the case of DC we have that the current and the RMS voltage is,



The potential in AC then is,
