A strand of 10 lights is plugged into an outlet. How can you determine if the lights are connected in series or parallel?A) Unscrew one light. If the other lights stay on, it's a series circuit.
B) Unplug the strand. If the first light stays on, it's a series circuit.
C) Unscrew one light. If the other lights turn off, it's a series circuit.
D) Cut the strand in half. If the plugged in half stays on, it's a series circuit.

Answers

Answer 1

Answer: series circuits, the current runs through all of them and they are conncted by the bulbs, so if you unscrew one, all light turn off

paralell, they are kinda independent, if you unscrew one, nothing happens to others

look at options
A. unscrew 1 light, if stay on, it's series, false, that's paralell

B. unplug, if stay on (then you have pozessed lights)

C. unsrew light, if stays on, it's parlell RIGHT ANSWER

D. cut strand in half (will cut power) if the plugged half stays on, then (pozessed circuit)

answer is C

None of these is a Physics problem. The numbers, and the fractions that
they appear in, might have come from Physics problems, but these are
nothing more than arithmetic exercises, and they can be whipped out

The material through which a mechanical wave travels is

Answers

A mechanical wave is a disturbance in matter that transfers energy through the matter.

Final answer:

Mechanical waves require a medium to travel through, such as a solid, liquid, or gas.

Explanation:

Mechanical waves require a medium through which they can travel. The medium can be a solid, liquid, or gas. Examples of mechanical waves include water waves, sound waves, and seismic waves.

The equation V=tk is used to describe the relationship between the volume of a gas tank and the time required to fill it . Is the symbol "K" a proportionally constant?

Answers

Answer:

The symbol 'K' is a proportionality constant because it shows the direct relationship between the gas tank volume, v, and the time required, t, to fill.

It is also the constant product of the ratio of the gas tank volume to the time required to fill it.

Which one is an accurate description of the process of erosion? A.

breaking rocks into smaller pieces

B.

forming rocks and depositing them in new places

C.

moving bits of rock and soil across the earth’s surface by water, wind, or glaciers

D.

water moving over the earth's surface and into the atmosphere

Answers

The accurate description of the process of erosion is when moving bits of rock and soil across the earth’s surface by water, wind, or glaciers. The answer is letter C.

An accurate description of erosion would be C. moving bits of rock and soil across the earth's surface by water, wind, or glaciers.

Erosion occurs over time when the Earth's surface begins to get worn down resulting in things like valleys, mud after a rainstorm, and rocks located on the bottom of a body of water.

Due to the force of gravity water easily flows from one place to another, which is why erosion occurs.

An observer on the earth sees a spaceship approaching at 0.54c. The ship then launches an exploration vehicle that, according to the earth observer, approaches at 0.82c. What is the velocity of the exploration vehicle relative to the spaceship? Give your answer as a decimal fraction of c, i.e. a β factor.

Answers

Answer:

Explanation:

Expression for relative velocity

= $(v_1+v_2)/(1+(v_1v_2)/(c^2) )$

= (.54 + .82 )c/ $1+ (.54 *.82)/(1)$

= 1.36 c / 1.4428

= .94 c

β = .94
