A solenoid has a cross-sectional area of 6.0 3 1024 m2, consists of 400 turns per meter, and carries a current of 0.40 A. A 10-t

urn coil is wrapped tightly around the circumference of the solenoid. The ends of the coil are connected to a 1.5-V resistor. Suddenly, a switch is opened, and the current in the solenoid dies to zero in a time of 0.050 s. Find the average current induced in the coil.

Complete Question:

A solenoid has a cross-sectional area of  6.0×10−4m2  consists of 400 turns per meter, and carries a current of 0.40 A. A 10-turn coil is wrapped tightly around the circumference of the solenoid. The ends of the coil are connected to a  1.5−Ω  resistor. Suddenly, a switch is opened, and the current in the solenoid dies to zero in a time of 0.050 s. Find the average current induced in the coil.

Answer:

I = 1.65 * 10⁻⁵A

Explanation:

I = Absolute value[-N(d∅/dt)/R]

N = 10 turns

∅ = BA cos Θ

B = μηI

B = (4π * 10⁻⁷)(400)(0.4)

B = 0.0002 T

A = 6.03 * 10⁻⁴m²

∅ = 0.0002 * 6.03 * 10⁻⁴

∅ = 12.12 * 10⁻⁸

d∅/dt = (12.12 * 10⁻⁸)/0.05

d∅/dt = 24.24 * 10⁻⁷

I =Abslute value of [-10 * ( 24.24 * 10⁻⁷)/1.5]

I = 1.6 * 10⁻⁵A

Which statement is incorrect when considering gases? 1. Gas molecules are in constant, random motion at room temperature 2. The
vova2212 [387]

Answer:

4

Explanation:

For gases :

1. The motion of gases molecule is in random manner at the room temperature.

2.The distance between the gas molecule is more and that is why gas can be compress.

3.The attraction force between the gas molecule is negligible or we can say that there is no any force between the gas molecules.that is why gas can be filled in the container.But the motion of the gas molecule does not stop they are still moving inside the container but the space for movement become less.When a gas container heated then the container start to vibrate because the movement of the gas molecule.

So the option 4 is incorrect.

A 2.00 kg block hangs from a spring balance calibrated in Newtons that is attached to the ceiling of an elevator.(a) What does t
tresset_1 [31]

Answer:

Part a)

Reading = 2.00 kg

Part b)

Reading = 2.00 kg

Part c)

Reading = 4.04 kg

Part d)

from t = 0 to t = 4.9 s

so the reading of the scale will be same as that of weight of the block

Then its speed will reduce to zero in next 3.2 s

from t = 4.9 to t = 8.1 s

The reading of the scale will be less than the actual mass

Explanation:

Part a)

When elevator is ascending with constant speed then we will have

F_{net} = 0

T - mg = 0

T = mg

So it will read same as that of the mass

Reading = 2.00 kg

Part b)

When elevator is decending with constant speed then we will have

F_{net} = 0

T - mg = 0

T = mg

So it will read same as that of the mass

Reading = 2.00 kg

Part c)

When elevator is ascending with constant speed 39 m/s and acceleration 10 m/s/s then we will have

F_{net} = ma

T - mg = ma

T = mg + ma

Reading is given as

Reading = \frac{mg + ma}{g}

Reading = 2.00\frac{9.81 + 10}{9.81}

Reading = 4.04 kg

Part d)

Here the speed of the elevator is constant initially

from t = 0 to t = 4.9 s

so the reading of the scale will be same as that of weight of the block

Then its speed will reduce to zero in next 3.2 s

from t = 4.9 to t = 8.1 s

The reading of the scale will be less than the actual mass

While passing through a human cell, an x-ray photon interacts with and inactivates the cell’s master molecule. What is the conse
Yuliya22 [10]

Answer:

Cell Death

Explanation:

Cell death is defined as the biological process which ceases the function of the cell to carry out. This can be caused due to the formation of new cells in place of old cells.

Or it can be cause due to some serious disease or may be caused due to the injury or due to the death of that organism to which these cells belong.

And another case is that when X-ray photon interact with the human cell while it passes through the cell, it   will damage the cell and cease it to function well and a more drastic condition occurs and that cell become dead.

Suppose the Sun moved twice the distance from Earth. Describe immediate and future changes to our planet. Justify your reasoning
Reptile [31]
Our year would now be 2.8 times longer, we would also be receiving only 1/4 of the energy from the sun that we currently do. This means that we’d now be out beyond the orbit of Mars and right at the edge of the asteroid belt, and things would rapidly get very cold with temperatures expected to drop by around 50 degrees Celsius on average, and that’s with our current atmospheric composition which would not be stable in the new conditions. And also, any living thing on earth would die.
