The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.

An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:

A = (1/2)*(Perimeter)*(Apothem)

The perimeter of the regular hexagon is just the length of one side multiplied with the number of sides. Since a hexagon has 6 sides,

P = 6(15) = 90in

A = 1/2 * 90 * 13
A = 585 square inches

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 3 k
tekilochka [14]

Answer:

50 N

Step-by-step explanation:

To help us find our answer, we need to use Newton's Second law

F = m \times a

Where F is the force (N), m is the mass (Kg) and a is the acceleration (m/s^2, on a planet this would just be the gravity)

So if we know that a person has a mass of 3Kg and weighs 30N, the acceleration (or the gravity on that planet is)

30 = 3 \times a\\a = 10 m/s^2

Now that we know the acceleration we can easily find the weight of the person.

F = 5 * 10 = 50 N
