Answer:

The magnetic field produced inside a current carrying solenoid is uniform.

Explanation:

A solenoid is a cylindrical coil of wire that produces a nearly uniform magnetic field, when electric current is passed through it.

The direction of magnetic field inside the solenoid will be along the axis of the solenoid and can be determined by a rule called the right hand thumb rule.

Right hand thumb rule states that, all the curled fingers of right hand signifies the flow of current in the circular direction in the coils and the thumb signifies the direction of magnetic field in the solenoid.

Citrus2011 [14]

Answer:

$\theta = 66.7 degree$

Explanation:

since force is applied downwards at some angle with the horizontal

so here we will have

$F_n = mg + Fsin\theta$

now we know that the box will not move if applied force is balanced by frictional force on it

so we will have

$Fcos\theta = \mu F_n$

$F cos\theta = \mu (mg + F sin\theta)$

$F(cos\theta - \mu sin\theta) = \mu mg$

$F = \frac{\mu mg}{cos\theta - \mu sin\theta}$

so here we can say

$cos\theta - \mu sin\theta > 0$

$tan\theta = \frac{1}{\mu}$

$\theta = tan^{-1}\frac{1}{\mu}$

$\theta = tan^{-1}(\frac{1}{0.43})$

$\theta = 66.7 degree$

Some laptops contain a second battery. what is this battery called

Phoenix [80]

I believe this battery is called Sheet battery.
Sheet battery is a flexible, ultra thin energy storage and production device formed by combining nano tubes with a conventional sheet of cellulose based paper. It acts as both a high-energy battery and super-capacitor, combining two components that are separate in traditional electronics.

Why was Democritus considered a philosopher and not a scientist?

Alika [10]

Answer:

Democritus had no scientific instruments to extend the reach of his senses, so all of his experiments were just 'mind experiments', but because Democritus was a philosopher, he thought more into depth about why we humans are alive which led to the atomic theory.

What happens when someone is walking across the carpeted room then touches a metal door knob

igomit [66]

Static electricity travels to the door knob because of the friction caused by the feet on the carpet. the friction traveled through the person, to their hand, and to the door knob because it is the best conductor.
