The bear fell because it slides to the surface of ice due to lack of friction.

One of these theories is that friction<span> causes the liquid layer of water to form on </span>ice<span>. </span>Friction<span> is the force that generates heat whenever two objects slide against each other. If you rub your hands together, you can feel them heat up. That's </span>friction<span> at work. When a </span>skate<span> moves over the surface of </span>ice, the friction<span> between the </span>skate<span> and the </span>ice<span> generates heat that melts the </span>outermost<span> layer of </span>ice<span>.</span>

A 2.00-kg ball is moving at 2.20 m/s toward the right. It collides elastically with a 4.00-kg ball that is initially at rest. 1)
loris [4]
Elastic collision is when kinetic energy before = kinetic energy after

Ek= 1/2mv^2

total before
Ek=1/2(2)(2.2^2) = 4.84 J

total after
Ek= 1/2(2+4)(v^2) = 3v^2

Before = after
4.84=3v^2 | divide by 3
121/75 = v^2 | square root both sides
v=1.27 m/s

What is the difference between liquid and fluid friction
frez [133]
Friction is used to refer to forces that resist relative motion, in general,whereas viscosity refers specifically to resistive forces that occur between layers of a fluid when fluids attempt to flow. Fluid friction is the force that resists the movement of a solid object through a fluid(liquid or gas). Sky divers falling down through the sky experience a type of fluid frictioncalled air resistance.

A hammer taps on the end of a 4.10-m-long metal bar at room temperature. A microphone at the other end of the bar picks up two p
xz_007 [3.2K]

Answer:

Speed of sound inside metal is ≅ 8200 \frac{m}{s}

Explanation:

Given :

Length of metal bar x = 4.10 m

From general velocity equation,

 v = \frac{x}{t}

Where v = speed of sound in air = 343 \frac{m}{s}

For finding time from above equation,

  t = \frac{x}{v}

 t = \frac{4}{343}

t = 0.01166 sec

Since pulses are separated by  t_{o} =  11.1 \times 10^{-3} = 0.0111 sec

So we take time difference,

\Delta t = t_{} -t_{o}  = 0.0005

So speed of sound in metal is,

 v = \frac{x}{\Delta t }

 v = \frac{4.10}{0.0005}

 v = 8200 \frac{m}{s}

What does the area between the line and the x-axis represent on a velocity vs. time graph?
Finger [1]

Answer:

It has been learned in this lesson that the area bounded by the line and the axes of a velocity-time graph is equal to the displacement of an object during that particular time period. ... Once calculated, this area represents the displacement of the object.
