To demonstrate the large size of the henry unit, a physics professor wants to wind an air-filled solenoid with self-inductance o

f 1.0 H on the outside of a 11 cm diameter plastic hollow tube using copper wire with a 0.79 mm diameter. The solenoid is to be tightly wound with each turn touching its neighbor (the wire has a thin insulating layer on its surface so the neighboring turns are not in electrical contact).
(a) How long will the plastic tube need to be?
(b) How many kilometers of copper will be required?
(c) What will be the resistance of this solenoid?
(Express all the answers to two significant figures and include appropriate units.)

In March 2006, two small satellites were discovered orbiting Pluto, one at a distance of 48,000 km and the other at 64,000 km. P
Natasha_Volkova [10]

Answer

given,

distance of first satellite = 48,000 Km

distance of second satellite = 64,000 Km

orbital period = 6.39 day

Using equation of time period

  T = \dfrac{2\pi r^{3/2}}{\sqrt{Gm_{pluto}}}

now, from the above equation we can say that only variable is Time period and r is the radii of orbit.

from the first satellite

   \dfrac{T_{charon}}{r^{3/2}_{charon}}=\dfrac{T_{sat1}}{r^{3/2}_{sat1}}

   T_{sat1}=\dfrac{T_{charon}\ r^{3/2}}{r^{3/2}_{charon}}

   T_{sat1}=\dfrac{6.39\times (48000)^{3/2}}{19600^{3/2}}

   T_{sat1}=24.5\ days

for second satellite

   T_{sat2}=\dfrac{T_{charon}\ r^{3/2}_{sat2}}{r^{3/2}_{charon}}

   T_{sat1}=\dfrac{6.39\times (64000)^{3/2}}{19600^{3/2}}

   T_{sat1}=37.7\ days

A clam of mass 0.12 kg dropped by a seagull takes 3.0 s to hit the ground. [Neglect friction.]
inna [77]
This is a defective, misleading question, and should never be asked in a Physics class.

There is no such thing as the force due to the impact.

If you know how long it takes the clam to stop once it begins to hit the dirt,
then you can calculate the impulse transferred to it, and tease a force out
of that.  But the question doesn't give us the time. 

It depends on the material of the surface.  Was the clam dropped onto dirt ? 
Into a dumpster ?  Onto grass ?  Concrete ?  Styrofoam ?  Mud ?  The answer
is different in each case, and we still need to know the short length of time
AFTER it first encountered whatever surface brought it to rest.

I would kick this question back to the Physics teacher.  It's meaningless,
and the longer you try to work on it, the more nonsense you'll plant into
your head that'll need to be dug out later.

WILL MARK BRAINLIEST ANSWER WITHIN HALF AN HOUR!! How did Faraday’s invention of the motor and the generator, explain that elect
Sphinxa [80]

Explanation:

1. He discovered electromagnetic induction

Before Faraday made it on the scene, scientists were aware of electricity, though they had done little to harness it for practical use. Take Giovanni Aldini, for example, who embarked on a tour around Europe in 1803 to electrocute a corpse in front of an audience. Electricity was such a mysterious force at the time, most laypeople saw it akin to magic more than anything else.

Faraday changed all that when he discovered electromagnetic induction in 1831. Through his innovative experiments, he found that by placing a conductor in a changing magnetic field, it would produce voltage across the conductor. In simpler terms? He found a way to cause an electric current, and that discovery was later applied to many devices we use today.

2. His inventions transformed the home, farm, and factory

Forget about that fancy fridge that produces three different types of ice cubes on a whim. Before the advent of harnessable electricity, nearly every facet of human life functioned differently than it does now. People in Faraday’s time got by at home with oil lamps, wooden ice boxes, and coal stoves by dry sinks.

Faraday’s discoveries also came to revolutionize work for small-time farmers in just about every way imaginable. Electricity eliminated manual labor like pumping water, so that rural families no longer spent hours of their day hauling water to livestock or to the house. Automated systems for tasks like milking cows kept farmers from crippling their hands, and the threat of barn fires from knocked over oil lamps during early-morning milking decreased. And although the industrial revolution was already underway when Faraway was born, cotton gins and power looms became old news as marvels like sewing machines and the telegraph refashioned the ways people worked and communicated. From cell phones to air conditioning, the modern conveniences we now take for granted were once but a fantasy without Faraday’s relentless wonder and curiosity to fuel them.

Keep your promise and mark me BRAINLIEST if you want..
