joja [24]

Answer:

Explanation:

Use the following equation:

E=\frac{q}{F} and solve for F:

F=\frac{q}{E} and filling in:

F=\frac{.0600}{1500}

F = 4.0 × 10^{-4 N

How should the magnetic field lines be drawn for the magnets shown below?
sergeinik [125]

 Option B is the correct answer that show how magnetic field lines should be drawn for the magnets shown in the figure.

<h3>What is Magnetic Line of Force ?</h3>

The Magnetic Line of Force of a magnet is defined as the line along which a free N - pole would tend to move if placed in the field of a line such that the tangent to it at any point gives the direction of the field at that point.

When the two unlike poles are placed to each other, there will be attraction. And when the two like poles are placed to each other, there will be repulsion. The reason is that the line of force tend to move from the north pole to the south pole.

From the given diagram, the two magnets are of the same south pole. They are of like pole and there will be repulsion between the two magnets.

Therefore, Option B is the correct answer that show how magnetic field lines should be drawn for the magnets shown in the figure.

How could rescue workers use squeezing or compressing to get energy to their flashlights during rescue missions?
svlad2 [7]

Answer:

They can do this with the help of mechanical power generated from the human muscle.

Explanation:

Since rescue workers engage in missions where it is usually difficult for them to get electrical energy to their devices and working tools, they could employ various materials that can be sourced around them to get energy to their tools. One of such is the mechanical power generated from the human body through squeezing and compressing.

Some green devices such as the dyno torch have been designed to be powered through this method. Repeated squeezing of its flywheel allows light to be generated.

Your roommate is working on his bicycle and has the bike upside down. He spins the 60 cm
tigry1 [53]
Diameter = 60 cm, Radius = 60/2 = 30 cm = 30/100 = 0.3 m.

The pebble in the tread goes by 3 times every second.

This is the same as 3 times per second.

Recall the unit of frequency is Hertz or per second, s⁻¹

So 3 times per second, Frequency, f = 3s⁻¹ or 3 Hertz

For angular motion:

Angular speed, ω = 2πf

                         = 2*π*3

                         = 6π   rad/s

Linear speed, v = ωr =  6π * 0.3 = 1.8π m/s


Linear acceleration, a = v² / r

                               a = 1.8π * 1.8π / 0.3 = 10.8π²   m/s²

Angular acceleration α = a/r  = 10.8π² / 0.3 = 36π² rad/s²


Angular speed = 6π rad/s ≈ 18.840 rad/s

The linear speed of the pebble = 1.8π  m/s ≈ 5.655 m/s

The angular acceleration = 36π² rad/s² ≈ 355.306 rad/s²

The linear acceleration of the pebble = 10.8π²  m/s ≈ 106.592 m/s²
