Electrons have negative charge,protons have a positive charge, and so a Neutron has NO CHARGE.

Hope this helps.

Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicul

ANEK [815]

Answer:

4.14 cm.

Explanation:

Given,

For Coil 1

radius of coil, r₁ = 5.6 cm

Magnetic field, B₁ = 0.24 T

For Coil 2

radius of coil, r₂ = ?

Magnetic field, B₂ = 0.44 T

Using formula of maximum torque

$\tau_{max}= NIAB$

Since both the coil experience same maximum torques

now,

$NIA_1B_1 = NIA_2B_2$

$A_1B_1 = A_2B_2$

$r_1^2 B_1 = r_2^2 B_2$

$5.6^2\times 0.24= r_2^2\times 0.44$

$r_2 = 4.14\ cm$

Radius of the coil 2 is equal to 4.14 cm.

. You are sitting on a beach watching the waves roll in. In 12 seconds, 6 waves roll by. What is the period of the waves (7)? Wh

Andrew [12]

Answer:

Explanation:

6 waves in 12 seconds

The period of a wave is defined as the time taken by the wave to complete one oscillations.

Here, 6 waves are completed in 12 seconds

So, one wave is completed in 2 seconds

So, the period of the wave is 2 second.

frequency is defined as the number of waves completed in one second. It is the reciprocal of period of the wave.

frequency = 1 / 2 = 0.5 Hertz

Let the wavelength is λ.

f = 660 kHz = 660000 Hz

the relation for the wave speed and the wavelength and the frequency is given by

v = f λ

where v is the speed of wave = 3 x 10^8 m/s

So, 3 x 10^8 = 660000 x λ

λ = 454.55 m

Tems11 [23]

For an individual to reduce his or her carbon footprint, they can:

Reduce the use of automobile
switch other renewable energy sources like solar energy

Hydrogen fuels are clean energy sources and should replace fossil fuels.

Carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases.

<h3>What is a carbon footprint?</h3>

A carbon footprint is the measure of the total amount of greenhouse gases that are emitted into the atmosphere each year by an individual.

Greenhouse gases are responsible for global warming.

For an individual to reduce his or her carbon footprint, they can:

Reduce the use of automobile
switch other renewable energy sources like solar energy

Hydrogen fuels are able to replace fossil fuels as they are clean energy sources.

An individual's carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases released.

In conclusion, greenhouse gases are responsible for global warming.
