Curved lines or straight lines can function as trend lines on a graph.

Answer: Option C

Explanation:

In general, trend refers to a pattern or behavior to represent a set of data in terms. In statistical point of view, trend lines are used in graph to represent a set of data values in terms of function in order to determine a relation between them for better understanding. The trend line can either be a curved line or a straight line which shows the direction on which the data travels.

Describe what Ecstasy looks like

stepan [7]

Ecstasy pills look a lot like candy. They are small, brightly colored, and stamped with funny images or clever symbols. They look like harmless little bits of nothingness people might swallow by the handful after a night of trick-or-treating. In reality, each ecstasy pill can do a great deal of damage. Hope this helped!

A police car on the side of the road (at rest) uses a radar gun to catch speeders as they approach it. The frequency the radar g

oee [108]

Answer:

$\Delta f = 1.49 \times 10^9 Hz$

Explanation:

Apparent frequency that is received to the speeder is given as

$f_1 = f_0\frac{v + v_o}{v}$

$f_1 = (8 \times 10^9)\frac{340 + v_o}{340}$

here we know that

$v_o = 65 mph = 29 m/s$

now we have

$f_1 = (8 \times 10^9)\frac{340 + 29}{340}$

$f_1 = 8.68 \times 10^9 Hz$

now the frequency that is received back from the speeder is given as

$f_2 = f_1\frac{v}{v- v_o}$

$f_2 = (8.68 \times 10^9}\frac{340}{340 - 29}$

$f_2 = 9.49 \times 10^9 Hz$

So difference is the frequency is given as

$\Delta f = 9.49 \times 10^9 - 8 \times 10^9$

$\Delta f = 1.49 \times 10^9 Hz$

A lamp has a current of 2.17 A. In hours, how long does it take for 1 mole of electrons to pass through the lamp?

Gennadij [26K]

Answer: The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

Explanation:

We are given:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of particles.

We know that:

Charge on 1 electron = $1.6\times 10^{-19}C$

Charge on 1 mole of electrons = $1.6\times 10^{-19}\times 6.022\times 10^{23}=9.6352\times 10^4C$

To calculate the time required, we use the equation:

$I=\frac{q}{t}$

where,

I = current passed = 2.17 A

q = total charge = $9.6352\times 10^4C$

t = time required = ?

Putting values in above equation, we get:

$2.17A=\frac{9.6352\times 10^4C}{t}\\\\t=\frac{9.6352\times 10^4C}{2.17A}=44402s$

Converting this into hours, we use the conversion factor:

1 hr = 3600 seconds

So, $44402s\times \frac{1hr}{3600s}=12.33hr$

Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

Explain what is meant by the term “good mother dinosaurs.”

Anna007 [38]

The term “good mother dinosaurs” is a term given to a type of dinosaur called Maiasaura which lived in the Upper Cretaceous Period, about 76.7 million years ago. This term is given to the Maiasaura because of the meaning of its name "Maia". This name means "good mother" because this type of dinosaur found near of the nest of eggs and embryos.
