What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Weight = (mass) x (acceleration of gravity)

Acceleration of gravity = 9.81 m/s² on Earth, 1.62 m/s² on the Moon.

The feather's weight is . . .

On Earth:  (0.0001 kg) x (9.81 m/s²) = <em>0.000981 Newton </em>

On the Moon:  (0.0001 kg) x (1.62 m/s²) = <em>0.000162 N</em>

The presence or absence of atmosphere makes no difference.  In fact, the numbers would be the same if the feather were sealed in a jar, or spinning wildly in a tornado, or hanging by a thread, or floating in a bowl of water or chicken soup.  Weight is just the force of gravity between the feather and the Earth.  It's not affected by what's around the feather, or what's happening to it.

Nataliya [291]

Answer:

A) mr = 100 kg

B) Fr = 210N

C) Ft = -199.5N

Explanation:

By conservation of the momentum:

mt*Vo = (mr + mt) * Vf  Solving for mr:

mr = mt*Vo / Vf - mt = 100 kg

The average force on the receiver:

mr *(Vf - 0) = Fr * Δt    Solving for Fr:

Fr = 210 N

The average force on the tackler:

mt * (Vf - Vo) = Ft * Δt    Solving for Ft:

Ft = -199.5 N

katrin [286]

If you stand on one side of a strike-slip fault and the block on the other side of the fault has moved to your left, this is known as a(n)  left lateral fault.

There are several distinct sorts of fault lines, and they are called based on the fault's movement and the fault plane's own direction. These faults may be found all over the world, but the most active and earthquake-producing ones are in the Pacific Ocean's Ring of Fire region.

When you gaze along the length of a fault line, the left side will move toward you while the right side moves away from you. This is referred to as a left-lateral fault.

Lubov Fominskaja [6]

El ejercicio completo es el siguiente:

Ana piensa en qué se podría hacer para volver a juntar los globos tras el

experimento del vídeo. ¿Cuál crees que es la respuesta correcta?

A. Esperar un rato a que se pase el efecto

B. Colocar entre los dos globos un tercer globo frotado con lana

C. Colocar entre los dos globos un objeto no electrizado

D. Colocar entre los dos globos un imán

Answer:

La respuesta correcta es la opción C

Explanation:

Como los dos globos están separados porque tienen la misma carga eléctrica, ahora Ana debe colocar un objeto no electrizado entre ellos para que los dos globos se vuelvan a juntar, como el objeto no electrizado tiene carga distinta a la de los globos hará que rápidamente se vuelvan a juntar.
