That's false. Visibility has nothing to do with weight.

Carbon Monoxide, Carbon Dioxide, Hydrogen Sulfide, Nitrogen, Oxygen, Methane, water vapor, and a bunch of other gases are invisible, but they all have plenty of weight.

Air is invisible. If your bedroom is, say, 12-ft long, 10-ft wide, and 7-ft high, then the air inside your room weighs around 65 pounds !

Magnitud del momento de una fuerza respecto a un punto cuando la línea de acción de la fuerza pasa por dicho punto.

Monica [59]

Answer:

τ = 0

Explanation:

The moment of a force is defined by

τ = F x r

where bold indicates vectors.

We can write this equation in module form

τ = F r sin θ

the amount without ea r is called the breaststroke and is the distance perpendicular to the pivot point.

The line of action of the force passes through the turning point whereby

r = 0,

Consequently the moment is also zero

τ = 0

A roller coaster is travelling 1 m/s at the top of the track. At the bottom of the track, 5 seconds later, it is travelling 36 m

lidiya [134]

Answer:

7m/s²

Explanation:

Given parameters:

Velocity at the top = 1m/s

Velocity at the bottom = 36m/s

Time = 5s

Unknown:

Average acceleration = ?

Solution;

Acceleration is the rate of change of velocity with time. It is expressed as;

A = $\frac{v -u}{t}$

v is the velocity at the top

u is the velocity at the bottom

t is the time taken

Now, insert the parameters and solve;

A = $\frac{36 - 1}{5}$ = 7m/s²
