Preview this picture of a roller coaster. Does it make you feel safe? How does the picture reinforce the idea of roller coasters being safe as stated in the article?

Answers

Answer 1

Answer: The coaster tracks serve to channel this force — they control the way the coaster cars fall. ... If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt-up, gravity applies a downward force on the back of the coaster, so it decelerates.

Explanation: They may be safe though!

The SI unit for energy is Newton true or false

Answers

Explanation:

false....it is joules

..........

The answer is false

The SI unit for energy is joules and not Newton. Energy can be described as the capability of an individual to perform work. Every day all living things carry out one form of work or the other. These might include walking, running, cooking, singing, driving etc. All these activities require energy, some require a whole lot of energy.

This is why the importance of energy for our day to day activities cannot be over emphasized.

Hence the SI UNIT for energy is joules.

Answers

Answer:

C. amount of charge on the source charge.

Explanation:

Electric field lines can be defined as a graphical representation of the vector field or electric field.

Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.

The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.

Lightning flashes and you hear a thunder clap for seconds later. the velocity of sound is 340 m/s. how far away did lightning strike ?

Answers

Answer:

For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.

Explanation:

hope it hep and if it doesnt sorry

The distance struck by the lighting flashes is 680 m.

The given parameters;

time taken to hear the thunder clap, t = 4 svelocity of sound, v = 340 m/s

The distance struck by the lighting is calculated by applying the principle of echo as follows;

[tex]v = \frac{2d}{t} \\\\2d = vt\\\\d = \frac{vt}{2} \\\\d = \frac{340 \times 4}{2} \\\\d = 680 \ m[/tex]

Thus, the distance struck by the lighting flashes is 680 m.

i have a physAn e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.
Which electrical device operates because of this effect?ics exam someone please help 9th grade &

Answers

Answer:

Generator.

Explanation:

In a generator, an e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.

The mode of operation of a generator is that a metal core with copper tightly wound to it (conductor coil) rotates rapidly between the two (2) poles of a horseshoe magnet type. Thus when the conductor coil rotates rapidly, it cuts the magnetic field existing between the poles of the horseshoe magnet and then induces the flow of current.

How much energy is transferred when the potential difference is 12V and the charge is 7.5C?

Answers

So you do 12 multiplied by 7.5 which is 90, so your answer is 90J :)

The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

What is energy?

In physics, energy is the capacity to carry out work. It might be potential, kinetic, thermal, electrical, chemical, radioactive, etc., among other types. Heat and work are other examples of energy being transferred from one body to another. Once it has been transmitted, energy is always allotted according to its nature. As a result, heat transmission could result in thermal energy while effort could provide mechanical energy.

Given the information in the question:

The potential difference, V = 12 Volts,

The charge, q = 7.5 C,

Calculate the energy, E by the formula given below,

E = [tex]VQ[/tex]

Substitute the values of charge and potential difference,

E = [tex]12*7.5[/tex]

E = [tex]90 Joules[/tex]

Therefore, the energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

A body completes one round of a circular path of radius 14m in 10 seconds. Calculate its average speed and average velocity at the end of one round.

Answers

Answer:

Average speed = 8.8 m/s

Average velocity = 8.8 m/s

Explanation:

From the question,

Avearge speed = 2πr/t................ Equation 1

Where r = 14 m, t = 10 s

Constant π = 22/7

Substitute this value into equation 1

Average speed = 2(22/7)(14)/10

Avearge speed = 8.8 m/s.

For a body moving in circular motion, The average speed and average velocity are equal.

Hence,

Average speed = 8.8 m/s

Average velocity = 8.8 m/s
