ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.A caterpillar tries to climb straight up a wall two meters high, but for every 2 cm up it climbs, it slides down 1 cm. Eventually, it reaches the top. When it reaches the top, it does not pull itself over so it will slide down 1 cm. At this point, the caterpillar was exhausted and fell to the ground. What is the total displacement?

0 up

0 down

0 n/a

What is your speed if you travel 7564 km in 23 hours? Convert this to miles per hour.

Answers

Answer:

[See Below]

Explanation:

Your average speed would be 204.35 mph.

i got appx. 204.3478 miles per hour because you convert 7564km/23hours to 4700miles/23hours, then divide 4700 and 23 by 23 to end up with 204.3478miles/1hour

Explain why the current is reduced as electrons move through a conductor.

Answers

The current is reduced as less energy is available to move electrons through the wire.


This is because electrons moving through the conducting substance collide with the electrons and ions.


This causes collisions which further more convert kinetic energy into thermal energy because of the fewer energy that is available, it reduces.


Moreover the resistivity factor of the conductor it self might play some role and the loss of energy too.
as current moves through the conductor; the resistance of the conductor causes the original amount of current to reduce do to the length and the cross section size of the wire.

In the series circuit below the power source is a 9-volt battery and three resistors are R1 = 7 ohm, R2 = 9 ohm and R3 = 2 ohm. What is the total resistance in the series circuit? R1 7 ohm + R2 9 ohm + R3 2 ohm = 18
Is this correct?

Answers

Yes indeed. You're on your way. In a series circuit, the total resistance is the sum of the individuals no matter what order they're in. Now, if the question goes on to ask what is the current in the circuit, that will be the source voltage divided by the total resistance that you have calculated.

An ultra-low friction pulley deal is as shown. The two weights experience an acceleration of 3.8m/s2. The first weight has 1.08kg. Find the mass of the second weight

Answers

Answer:

The mass of the second weight is approximately 0.477 kg

Explanation:

The given parameters are;

The acceleration experienced by the two weights = 3.8 m/s²

The mass of the first weight = 1.08 kg

The formula for the acceleration, a, of weights attached to a friction pulley, is given as follows;

a = (g \cdot (M - m))/(M + m)

Where;

a = The common acceleration of the two weights

g = The acceleration due to gravity = 9.81 m/s²

M = The mass of the first weight = 1.08 kg

m = The mass of the second weight

Therefore, we have;

m = (M\cdot (g -a ))/(g + a) = (1.08* (9.81 -3.8 ))/(9.81 + 3.8) \approx 0.477

The mass of the second weight = m ≈ 0.477 kg

The mass of the second weight ≈ 0.477 kg.

I have to make three videos for physics about Newton's three laws of motion but I don't want to be in the videos or talk in them. Any ideas on how I could do that?

Answers

Answer:

You should face your fears sometimes, and get in front of a crowd do present your ideas. Not everyone is good at it, and many people get anxious when they have to speak in front of people but it’s best if you just do it and get it over with and maybe it won’t be as intimidating next time :)

A ball rolls from point A to point B. The total energy of the ball at point A isn’t the same as the sum of its potential energy and kinetic energy at point B. Which statement best explains this situation?The rolling ball doesn’t follow the law of conservation of energy. Some of the ball’s energy is transformed to thermal energy. The rolling ball loses some of its energy because of gravity. The ball absorbs some of its own potential energy.
