Two people are standing in the middle of a frozen pond that is frictionless. They want to move to the edges of the pond but are

unable to get any traction to walk on the slick surface. If they push against each other, what can be said about the force that is created between them?
if one person has more mass than the other , what can u say about their accelerations?​

Answer:

if their frozen they cant contract heat by rubbing against each other which will result in a death of hypothermia.but they could've done something good for the world and maybe the sun will come then the can swim or go whatever way the came to get out of the pond.

1. Determina el momento que produce una fuerza de 7 N tangente a una rueda de un metro de diámetro, sabiendo que el punto de apl
Rudik [331]

Answer:

τ= F r     into the blade

Explanation:

The moment of a force is defined by

         τ = F x r

where the bold indicates vectors

Let us write in the expression in magnitude

         τ = F r sin θ

in our case the force is tangent to the wheel therefore the angle between F and the radius is 90º, and the sin 90 = 1

       τ= F r

The direction of τ can be used by the rule of the right hand, the fingers curve in the direction of the torque when advancing from the force to the radius and the thumb points in the direction of the torque.

In this case, for a clockwise rotation, the fingers are curved in the direction and the thumb points into the blade, this is the direction of the τ.

TRASLATE

El momento de una fura es definido por

         τ = F x r

donde la negrillas indican vectores

Escribamos en ta expresión en magnitud

          τ = F r sin θ

en nuestro caso la fuerza es tangente a la rueda por lo tanto el angulo entre F y el radios es 90º, y el sin 90=1

        τ = F r

la dirección de tau la podemos  usar la regla de la mano derecha, los dedos curva en la dirección del torque al avanzar dese la fuerza al radio y el pulgar apunta en la dirección del torque.

En este caso para un giro en sentido horario los dedos se curvan ente sentido y el pulgar apunta hacia dentro de lla hoja, esta es la dirección del troque

PLLEEEASE HELP!!! How does archimedes' principle explain how much fluid is displaced by an object?
Crank

The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg.

How does the amount of energy in light change as the wavelength increases
Phoenix [80]

Answer

we know,

E= \dfrac{hc}{\lambda}

where

E = energy  

h = planks constant

λ = wavelength

from the above equation, we can see that energy is inversely proportional to wavelength.

E\ \alpha\ \dfrac{1}{\lambda}

that is why  

Violet color light has low wavelength but the energy of  Violet light is very high whereas red light has low energy and high wavelength.

2. A water wave has a speed of 4 m/s and 10
nikklg [1K]

Answer: 12.12 m

Explanation:

We have the following data:

v=4 m/s is the speed of the water wave

f=\frac{10 waves}{30 s}=0.3 Hz is the frequency of the water wave

Now, the speed of a wave is given by the following equation:

v=\lambda f

Where \lambda is the wavelength.

Isolating \lambda:

\lambda=\frac{v}{f}

\lambda=\frac{4 m/s}{0.3 Hz}

Finally:

\lambda=12.12 m This is the water wave wavelength
