What is the density at 20oC of 12.0 milliliters of a liquid that has a mass of 4.05 grams?0.338 g/mL
2.96 g/mL
16.1 g/mL
48.6 g/mL

Answers

Answer: A. 0.338 g/ml

Explain:
D = m/V = 4.05/12 = 0.3375 = 0.338 g/mL

The density at 20°C of 12.0 milliliters of a liquid that has a mass of 4.05 grams is 0.3375g/mL.

HOW TO CALCULATE DENSITY:

The density of a liquid can be calculated by dividing the mass of the liquid by its volume. That is;

Density (g/mL) = mass (g) ÷ volume (mL)

According to this question, a liquid at 20°C has a volume of 12.0 milliliters and a mass of 4.05 grams. The density is calculated as follows:

Density (g/mL) = 4.05g ÷ 12mL

Density of liquid (g/mL) = 0.3375g/mL

Therefore, the density at 20°C of 12.0 milliliters of a liquid that has a mass of 4.05 grams is 0.3375g/mL.

Lan tries to make a 10 W lightbulb light up by connecting it to a battery with
an insulated copper wire. When the lightbulb does not light up, she assumes
that the battery is dead. What can she do to make an electric current flow
through the lightbulb?
A. Replace the battery with a coil of the wire, and then pass a magnet
back and forth through the coil.
B. Replace the battery with a magnet, and then pass a piece of wire
back and forth over the magnet.
O C. Wrap a magnet with several coils of the wire, and then hold the
lightbulb close to the wire.
D. Wrap the lightbulb with several coils of the wire, and then hold a
magnet close to the wire.

Answers

Answer:

A

Explanation:

When a magnet passes through something that's copper, there is a reaction that generates an electric pulse. Passing a magnet back and forth through the wire is much more likely to generate the electrical charge needed then the other options given.

Lan can  replace the battery with a coil of the wire, and then pass a magnet back and forth through the coil to make an electric current flow through the lightbulb. Hence option (A) is correct.

What is electromagnetic induction ?

The generation of an electromotive force (emf) across an electrical conductor in a fluctuating magnetic field is known as electromagnetic or magnetic induction.

Induction was first observed in 1831 by Michael Faraday, and James Clerk Maxwell mathematically named it Faraday's law of induction. The induced field's direction is described by Lenz's law. One of the four Maxwell equations in his theory of electromagnetic, the Maxwell-Faraday equation is a generalization of Faraday's law.

When Lan replace the battery with a coil of the wire, and then pass a magnet back and forth through the coil, it generates electromagnetic induction and electric current flows through the lightbulb.

Describe the difference between a transverse wave and longitudinal wave. Include the parts that you would find on a transverse wave and longitudinal wave. Give an example of each.



PLEASE HELP! ITS A WRITTEN RESPONSE!

Answers

A transverse wave is a moving wave in which the current is perpendicular to the direction of the wave or path of propagation. A longitudinal wave are waves in which the displacement of the median is in the direction of the propagation.
Example:
Transverse- pond ripple
Longitudinal- crest and troff

Answer:

A transverse wave is a moving wave in which the current is perpendicular to the direction of the wave or path of propagation. A longitudinal wave are waves in which the displacement of the median is in the direction of the propagation.

Read the excerpt from "Healthy Eating."

But no one can ignore the damage being wrought by all this bad eating. More than one out of three adults in the United States -- 37.5 percent -- are obese, according to the Centers for Disease Control and Prevention. Some of the leading causes of death -- heart disease, stroke and type 2 diabetes -- are directly linked to obesity. And childhood obesity has tripled in the last 30 years. With more than a third of kids between 6 and 19 considered obese, the CDC reports, they are at substantially more risk for developing cardiovascular disease, diabetes, bone and joint conditions, and cancer.

The author's argument that a poor diet can be harmful to a person's health is _____________________.

ineffective, because it lacks clear and reasonable evidence.

ineffective, because it leaves the reader with questions.
