Write an equation that expresses the following relationship.
ahrayia [7]

Given:

u varies directly with the square of p and inversely with d.

To find:

The equation for the given situation.

Solution:

If y is directly proportional to x, then

y\propto x

If y is inversely proportional to x, then

y\propto \dfrac{1}{x}

It is given that u varies directly with the square of p and inversely with d. So,

u\propto \dfrac{p^2}{d}

It can be written as:

u=k\dfrac{p^2}{d}

Where, k is the constant of proportionality.

Therefore, the required equation is u=\dfrac{kp^2}{d}.

A force vector M points 3 N in the x-direction and 4 N in the y-direction. What is Vector M’s magnitude?
julsineya [31]

Answer:

5 N.

Step-by-step explanation:

Given that,

A force vector M points 3 N in the x-direction and 4 N in the y-direction.

We need to find the magnitude of vector M. The magnitude of the vector when they are perpendicular to each other is given by :

M=\sqrt{3^2+4^2} \\\\M=5\ N

So, the required magnitude of M is 5 N.
