What is \( \sqrt{\frac{16}{4}} \)?
To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:
\( \sqrt{\frac{16}{4}} \)
\( \frac{\sqrt{16}}{\sqrt{4}} \)
\( \frac{\sqrt{4^2}}{\sqrt{2^2}} \)
\( \frac{4}{2} \)

One Horsepower (hp) is equal to how many watts?
746
Power is the rate at which work is done, P = w/t, or work per unit time. The watt (W) is the unit for power and is equal to 1 joule (or newton-meter) per second. Horsepower (hp) is another familiar unit of power used primarily for rating internal combustion engines. 1 hp equals 746 watts.
The electrical potential difference between two points is called:
voltage
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
A major difference between sound waves and light waves is which of the following?
all of these are correct
A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.
Connecting the 4 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 15A configuration. Connecting the 4 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 15V 60A configuration. Using a series-parallel connection, 2 batteries can be connected in series and 2 can be connected in parallel resulting in a 30V 30A configuration.
Solve 3c + 2c = 9c - 9y + 8 for c in terms of y.
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
3c + 2y = 9c - 9y + 8
3c = 9c - 9y + 8 - 2y
3c - 9c = -9y + 8 - 2y
-6c = -11y + 8
c = \( \frac{-11y + 8}{-6} \)
c = \( \frac{-11y}{-6} \) + \( \frac{8}{-6} \)
c = 1\(\frac{5}{6}\)y - 1\(\frac{1}{3}\)
Which of the following describes how a person's genes express themselves in physical characteristics?
phenotype
A person's genotype is their genetic makeup and includes both dominant and recessive alleles. Phenotype is how the genes express themselves in physical characteristics.
In fermentation, what replaces oxygen in anaerobic respiration?
lactic acid or alcohol
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
