The product is 1487.9286. Since we're dealing with money, there can Only be 2 numbers after the decimal point, so you'd round it to £1487.93

To estimate you would do 50x30, which equals 1500. That would make it £1500(or dollars or whatever it's the same number).

I think the mixed number would be 1487 pounds and 93 pence (again dollars or whatever it's the same number).

Then the multiply is just the product.

Hope I helped :)

I don't understand linear relationships. Can someone explain how it works

Vesna [10]

Linear relationships can be expressed in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable is multiplied by the slope coefficient, added by a constant, which determines the dependent variable.

Answer:

See below

Step-by-step explanation:

(a) Field lines

A negatively charged particle has an electric field associated with it.

The field lines spread out radially from the centre of the point. They are represented by arrows pointing in the direction that a positive charge would move if it were in the field.

Opposite charges attract, so the field lines point toward the centre of the particle.

For an isolated negative particle, the field lines would look like those in Figure 1 below.

If two negative charges are near each other, as in Figure 2, the field lines still point to the centre of charge.

A positive charge approaching from the left is attracted to both charges, but it moves to the closer particle on the left.

We can make a similar statement about appositive charge approaching from the left.

Thus, there are few field lines in the region between the two particles.

(b) Coulomb's Law

The formula for Coulomb's law is

F = (kq₁q₂)/r²

It shows that the force varies inversely as the square of the distance between the charges.

Thus, the force between the charges decreases rapidly as they move further apart.
