The equation for free fall at the surface of a celestial body in outer space (s in meters, t in seconds) is sequals10.04tsqua

Sindrei [870]

Answer:

1.42 s

Explanation:

The equation for free fall of an object starting from rest is generally written as

$s=\frac{1}{2}at^2$

where

s is the vertical distance covered

a is the acceleration due to gravity

t is the time

On this celestial body, the equation is

$s=10.04 t^2$

this means that

$\frac{1}{2}g = 10.04$

so the acceleration of gravity on the body is

$g=2\cdot 10.04 = 20.08 m/s^2$

The velocity of an object in free fall starting from rest is given by

$v=gt$

In this case,

g = 20.08 m/s^2

So the time taken to reach a velocity of

v = 28.6 m/s

$t=\frac{v}{g}=\frac{28.6 m/s}{20.08 m/s^2}=1.42 s$

Some magnets have just one pole <br> Truth or false ?

leva [86]

False

-A magnet can never have one pole, even a simple magnet was cut, each end would have an opposite south(-) or north(+) pull.

What is the correct answer?

sashaice [31]

Answer:

D) 4

Explanation:

Roots of a polynomial must be factors of the last term.

In this case, the factors of 6 are +1, -1, +2, -2, +3, -3, +6, -6. The only factor that doesn't show up, given the options, is 4. This means that D is the correct answer.
