An observer sits in a boat watching wave fronts move past the boat. The distance between successive wave crests is 0.80 m, and t

Rama09 [41]

To solve this problem we will use the three requested concepts: Wavelength, frequency and period.

The wavelength is the distance between each crest, therefore it is already given and is 0.8m

<em>The correct answer is C.</em>

The frequency can be described as a relationship between wave speed and wavelength therefore

$f = \frac{v}{\lambda}$

$f = \frac{2.2}{0.8}$

$f = 2.75Hz \approx 2.8Hz$

<em>The correct answer is B.</em>

The period is the inverse of the frequency therefore

$T = \frac{1}{f}$

$T = \frac{1}{2.8}$

$T = 0.35s$

<em>The correct answer is B.</em>

A transformer on a 220 V line has 55 loops on the primary and 440 loops on the secondary and draws a 4.00 a current. Assuming no

Artyom0805 [142]

For transfomers (robots in disguise), there are equations to help us solve these problems.

Here are the equations you need:

$\frac{V_{p}}{V_{s}}= \frac{n_{p}}{n_{s}}$

$V_{p}$ is our V primary, $v_{s}$ is our V secondary, $n_{p}$ is our number of loops on our primary and $n_{s}$ is number of loops in our secondary.

Plugging our known values in, we can solve for the secondary voltage.

$\frac{220}{V_{s}}= \frac{55}{440}$
$V_{s} = 1760V$

For current, we have another equation:

$V_{p}I_{p}=V_{s}I_{s}$

Just like before, we can plug in our known values:

$(220V)(4A)=(1760V)I_{s}$
$I_{s}= 0.5A$

Since we are told there are no losses, the input power must equal output power.

(0.5A)(1760V)=(220V)(4A) = 880W

A true experiment involves the identification and control of variables. What is an example of a scientific investigation that mi

Karolina [17]

Answer:

Explanation:

Since the definition of true experiment has been provided in the question, let's proceed to define some other parameters.

Scientific investigation <u>that might not involve a true experiment is called non-experimental research </u>while the one that involves a true experiment is called experimental research.

Non-experimental researches are usually descriptive in nature. An example of a non-experimental research is the observation and recording of the number and the beak type of birds that visits a park. As seen, this experiment does not have it's variables set out for identification or even control.
