Neutralization usually involves an acid producing a salt. A double displacement reaction usually produces a precipitate in which the more reactive metal displaces the less reactive one.

Gauss law states that the electric flux through any closed surface is proportional to the net electric charge inside the surface. This is expressed mathematically in the form of:

Φ = Q / εo

Where,

Φ = the electric flux = unknown (which we have to find for)

Q = the net electric charge = 5.0 µC = 5 E-6 C

εo = the permittivity of free space = a constant value = 8.85 E-12 C^2 / N m^2

Plugging in the values into the equation will result in:

Φ = 5 E-6 C / (8.85 E-12 C^2 / N m^2)

Φ = 564,971.75 Wb = <span>5.6 x 10^5 Wb </span>

Calculate the kinetic energy of a motorcycle of mass 60kg travelling at a velocity of 40km/h

ELEN [110]

Answer:

1848.15J

Explanation:

KE =1/2 mv^2

Mass = 60kg, velocity =40km/h =11.11m/s

Hence

KE =30 x(11.1)^2 /2 = 1848.15J

According to your graph, does the wave speed change with wave length?

fiasKO [112]

Yes

Explanation:

From the graph, we can deduce that the wavelength changes with the speed of the wave.

This is a simple linear graph. A linear graph has a steady gradient and it shows two variables that increases proportionately.

Using the graph, we can establish that as the wavelength of the wave increases the time taken for one wave to pass through increases.

The speed of a wave is given as:

V = fλ

f is the frequency of the wave i.e the number of waves that passes through a point per unit of time

λ is the wavelength of the wave

The vertical axis on the graph shows the time for 1 wave trip, this is the wave period, T

f = $\frac{1}{T}$

Therefore;

speed of the wave = $\frac{λ}{T}$

This can be evaluated by solving slope of the graph and finding the inverse.

We can see that as the speed of the wave changes, the wavelength will change.
