To measure the magnetic strength of a bar magnet use a gauss meter for the test.

<h3>Test for magnetic strength of a bar magnet</h3>

The strength of a magnet is determined by the pull force exerted by the magnet when it is pulled away from a magnetic material like steel.

Use the following steps to determine the strength of a magnet;

  1. Get a gauss meter and magnet, take both where no other magnetic material can be located.
  2. Place the gauss meter directly on on the surface of one of the magnet's poles.
  3. Locate the needle on the gauss meter and find the corresponding heading. If the needle points far left or far right, then strength of the magnetic field is high and vice versa.

List 5 types of action energy and 4 types of potential energy
Taya2010 [7]
Well, kinetic energy is defined as energy in motion (or as you said, action energy). Now, in order to characterize something as kinetic energy, it needs to be in motion (e.x., movement on a rollercoaster, a ball falling, a ball rolling, a person running, or a car in motion, really, anything moving).
Potential energy is stored energy. For example, it could be the farthest point back when you pull a slingshot. Or being at the very top of a hill right before you fall back down it, or holding a ball at its highest point before you drop it. Another example, is water stored behind a dam waiting to be released. Hope this helps!

Consider the reaction X mc022-1.jpg Y + 2Z . If the molar solubility of X is multiplied by 2, the value of Ksp will be multiplie
Alex777 [14]
X -> Y + 2Z

So there are 2 different particles. 1 mol of X produces 1 mol of Y and 2 moles of Z.

Kps = [Y] [Z]^2

We will call “s” (solubility) the molarity of X

So the molarity of Y+ is also “s” (same number)

And the molarity of Z is “2s” (twice as much)

Kps = s*(2s)^2 = s*4s^2=4s^3

If s is multiplied by 2:

Kps = 4*(2s)^3=4*2^3*s^3=4*8*s^3

So Kps is multiplied by 8.

Explain how the plants of a tropical rain forest contribute to the characteristic hot, humid weather associated with the area. U
Talja [164]

Answer: The atmosphere of trophic rainforest is hot and humid due to high rate of transpiration.

Explanation:

The tropical rainforest is a biome which exhibit rich biodiversity of plants and animals. The average temperatures in this region remain high with warm summer. It remains frost free. The soil is nutrient deficient. Due to hot temperature the rate of transpiration remains high as a result the concentration of the water vapors remain high. This is responsible for increasing the humidity in the atmosphere also this region receives appreciable amount of rainfall annually. The average rainfall range is 200-450 centimeters.

A proton initially at rest is accelerated by a uniform electric field. The proton moves 4.76 cm in 1.10 x 10^-6 s. Find the volt
iVinArrow [24]

Answer:

The voltage drop through which the proton moves is 39.1 V.

Explanation:

Given that,

Distance = 4.76 cm

Time t=1.10\times10^{-6}\ s

We need to calculate the acceleration

Using equation of motion

s = ut+\dfrac{1}{2}at^2

Where, s = distance

a = acceleration

t = time

Put the value in the equation

4.76\times10^{-2}=\dfrac{1}{2}\times a \times(1.10\times10^{-6})^2

a=\dfrac{2\times 4.76\times10^{-2}}{(1.10\times10^{-6})^2}

a=7.87\times10^{10}\ m/s^2

We need to calculate the voltage drop

Using formula of electric field

F=qE

F = q\dfrac{V}{d}....(I)

Using newton's second law

F = ma....(II)

Put the value of F in equation (I) from equation (II)

ma=\dfrac{qV}{d}

V=\dfrac{mad}{q}

Where, q = charge

a = acceleration

d = distance

m= mass of proton

Put the value into the formula

V=\dfrac{1.67\times10^{-27}\times7.87\times10^{10}\times4.76\times10^{-2}}{1.6\times10^{-19}}

V=39.1\ V

Hence, The voltage drop through which the proton moves is 39.1 V.

f a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave? A. 1,200 m/s B. 1,500 m/s C. 1,80
GalinKa [24]

Answer: 1500 m/sec. ( b )

Solution:

V= f (λ)

Speed = frequency. Wavelength  

And frequency = 1/time period

First we will find the frequency :

Frequency = 1/time period

1/0.006 = 166.67 Hz

Using this in the equation:

Speed = frequency. Wavelength  

V= f (λ)

9 × 166.67  

= 1500.03 ≈ 1500

V (Speed) = 1500 m/s.

Note: Do not forget to mention the units or otherwise they may cost you marks!
