A coil of insulated wire is wound many times around an iron bar. The wire is connected to a battery and a contact switch. The contact switch is alternately flipped closed and left closed, so the wire carries a current through it, and then flipped open and left open, so that the current stops. Describe what magnetic fields are created, if those magnetic fields in turn induce an emf, and whether the induced emf is in the direction of the original current or opposite to it. Justify your answer using Lenz's law and the conditions which can cause a magnetic field to induce an emf. You may draw a diagram if it helps you to visualize the apparatus.

Simon is riding a bike at 12 km/h away from his friend Keesha.He throws a ball at 5 km/h back to Keesha, who is standing still on a sidewalk. 
How fast would Keesha say the ball is traveling toward her?

Answers


I notice that even though we're working with frames of reference
here, you never said which frame the '5 km/hr' is measured in.

In fact !  You didn't even say which frame the '12 km/hr' of his
bike is measured in.

So there are several different ways this could go.  I'll do it the way
I THINK you meant it, but that doesn't guarantee anything.

-- Simon is riding his bike at 12 km/hr relative to the sidewalk,
away from Keesha.

-- He throws a ball at Keesha, at 5 km/hr relative to his own face.

-- Keesha sees the ball approaching her at (12 - 5) = 7 km/hr
relative to the ground and to her.

A skier starting from rest accelerates in a straight line down a 43,000 m slope at 1 m/s. How fast were they moving after 5 s?

Answers

Answer:

5m/s

Explanation:

The skier accelerates at 1 m/s, then, the acceleration is:

a=1(m)/(s^2)

to find the speed after 5 seconds you use the following formula:

a=(v-v_o)/(t)

but vo = 0m/s because the skier is at rest at the beginning.

You do v the subject of the formula:

v=at=(1(m)/(s^2))(5s)=5(m)/(s)

hence, the velocity is 5m/s

What is the slope of the line if the rise of a line on a distance versus-time graph is 900 meters and the run is 3 minutes?

Answers

Slope = (rise) / (run) = (900 meters) / (3 minutes). / / / Slope = 300 meters/minute or 5 meters/sec.
Rise/run so 900/3 which is 300 i am not sure if i am right but i think thats the answer

What is the value of w in the equation
1/2w + 7 = 2w - 2

Answers

(1)/(2) w + 7 = 2w - 2

First, replace the numerator with 'w'.
(w)/(2) +7=2w-2
Second, multiply both sides by 2.
w + 14 = 4w - 2
Third, subtract 'w' from both sides.
14 = 4w - 4 - w
Fourth, simplify to 3w - 4.
14 = 3w - 4
Fifth, add '4' to both sides.
14+4=3w
Sixth, add 14 + 4.
18 = 3w
Seventh, divide both sides by '3'.
(18)/(3) =w
Eighth, since 6 goes into 3 to get 18, simplify the fraction to 6.
6 = w
Ninth, switch the sides.
w = 6

Answer: w = 6

Why do prokaryotic cells usually reproduce more quickly than eukaryotic cells? Choose 1 answer:

(Choice A) A Eukaryotic cells are more structurally complex than prokaryotic cells.

(Choice B) B Eukaryotic cells have less DNA than prokaryotic cells.

(Choice C) C Eukaryotic cells have more cell walls than prokaryotic cells.

(Choice D) D Eukaryotic cells are smaller than prokaryotic cells.

Answers

Prokaryotic cells reproduce more quickly than eukaryotic cells because the latter are more structurally complex. The correct option is A.

Structural complexity of cells

Eukaryotic cells have nuclei and membrane-bound organelles such as mitochondrion. This is unlike prokaryotic cells whose DNA lies freely in the cytoplasm and lacks membrane-bound organelles.

In order words, eukaryotic cells are structurally more complex than prokaryotic cells. Thus, reproductive times in prokaryotes are usually quicker than in eukaryotes.
