Which of the following conversion factors would you use to change 18 kilometers to meters? A.) 1,000 m/1 km
B.) 1 km/1,000 m
C.) 100 m/1 km
D.) 1 km/100 m

Answers

Answer:

The answer is A) 1,000 meters = 1 Kilometer.                                                        

Explanation:

To convert 18 Kilometers into meters, one would have to  multiply the figure given in Kilometer by 1000.

Therefore we have 18 x 1000

= 18,000.

So 18 Kilometers is also 18,000 meters when converted.

Cheers!

A ball of clay sinks when placed in water. The same piece of clay floats if it is made into the shape of a boat.Why does the clay float when made into the shape of a boat?
a. The clay is less dense when stretched into the shape of a boat.
b. The buoyant force is greater on the clay when it has a spherical shape.
c. The boat shape displaces a greater volume of water than the ball shape.
d. The weight of the clay boat is less than the weight of the clay ball.

Answers

The correct answer is definitely d. The weight of the clay boat is less than the weight of the clay ball.
In such situations, the point that we should take as a basis to resolve a question is weight. If the weight of clay is less than that of a clay ball, the clay will float.

Answer:

c. The boat shape displaces a greater volume of water than the ball shape.

I don't understand why when you use a straw the higher pressure outside of it pushes the water up the straw.

Answers

When material stuff is free to move, it moves away from stronger force on it to weaker force on it. OK ? Now take it to the next step: When material stuff is free to flow ... like liquid or gas ... it flows from higher pressure to lower pressure. That's what makes wind, and that's why water comes out of a garden hose when you open the nozzle. It doesn't amaze you at all when you INCREASE the pressure at one end of the straw (blow into it), and air moves DOWN and out of it. So it shouldn't bother you that when you DECREASE the pressure at your end, anything that's free to flow UP the straw will do that.
pressure is force acting on an area .
in the same area, more pressure means more force.

2 person, pressure outside and one in straw push water against each other. more pressure outside, so more force it pushes ... where will the water flow?

One result of wave refraction is that _____.wave energy is concentrated on headlands projecting into the water
wave energy is largely dissipated before the waves reach shore
wave energy is concentrated in the recessed areas between headlands
headlands are enlarged by sediment deposited on their seaward side

Answers

I think the correct answer from the choices listed above is the first option. One result of wave refraction is that wave energy is concentrated on headlands projecting into the water. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.

 One result of wave refraction is that wave energy is concentrated on headlands projecting into the water. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.

Explanation:

Refraction of waves comprises a change in the management of waves as they traverse from one medium to different. Refraction, or the bending of the track of the waves, is conducted by a transition toward speed and wavelength of the waves.

How has the model of our solar system changed over time?

Answers

It depends.Ptolemy was one of the most famous astronomers who was convinced that or solar system was geocentric, or revolving around the earth. Then, Copernicus came around, along with Galileo, and the attempted to convince people that that wasn't true, but that we were revolving around the sun. In fact, if you're writing an essay, a good point to add would be that Galileo spent a large part of his life imprisoned for "disobedience of the (Roman) Gods.)"

It always depends of how our solar system changed over time.

A snail can move approximately 0.30 meters per minute. How many meters can the snail cover in 15 minutes?

Answers

A snail can move approximately 0.30 meters per minute then it would cover 4.5 meters in 15 minutes.

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.

As given in the problem a snail can move approximately 0.30 meters per minute and we have to calculate the distance covered in 15 minutes.

speed of the snail  =  0.30 meters per minute

time = 15 minutes

distance covered by the snail = speed  ×time

distance covered by the snail = 0.30 ×15

distance covered by the snail = 4.5 meters

Thus, the distance covered by the snail in the 15 minutes would be 4.5 meters.

distance = velocity (or speed) x time
so, distance = 0.30 meters.min x 15 mins
distance = 4.5 meters
