Dr. Alley has helped drill many holes in ice sheets. Special tools can be lowered down the holes on cables, and tracked to learn

the shapes of the holes. Initially, the holes are straight up and down. Years later, the holes are bent, because the ice in the ice sheet is flowing. What does it mean to say that the ice is flowing?

Answer:

Much like shakes in the mantle or iron warmed by a metal forger, the ice is practically hot enough to soften, and distorts as gravity pulls on it, without loosening up into lumps.

Explanation:

  • Materials warmed however not exactly to their liquefying point can results in deformation without breaking or dissolving.
  • It results from the extraordinary convection cells in the mantle. In the event that you list the temperature of the ice in degrees F, it is much colder than the mantle, or iron warmed by a metalworker, or a chocolate bar in your pocket.
  • Be that as it may, the ice has been warmed from total zero nearly to the liquefying temperature, much the same as the mantle and the iron and the chocolate, so the pressure from gravity can make the ice distort or stream.

How to solve number 10
Vinil7 [7]

The 'formulas' to use are just the definitions of 'power' and 'work':

Power = (work done) / (time to do the work)

and  

Work = (force) x (distance) .

Combine these into one. Take the definition of 'Work', and write it in place of 'work' in the definition of power.

Power = (force x distance) / (time)

From the sheet, we know the power, the distance, and the time.  So we can use this one formula to find the force.

Power = (force x distance) / (time)

Multiply each side by (time):  (Power) x (time) = (force) x (distance)

Divide each side by (distance): Force = (power x time) / (distance).

Look how neat, clean, and simple that is !

Force = (13.3 watts) x (3 seconds) / (4 meters)

Force = (13.3 x 3 / 4) (watt-seconds / meter)

Force = 39.9/4 (joules/meter)

<em>Force = 9.975 Newtons</em>

Is that awesome or what !

For which length of wire are the readings of resistance the most precise
levacccp [35]
The resistance of a wire is directly proportional to the length of the wire. That is the longer the length of the wire, the higher the resistance and the shorter the length of the wire, the smaller the resistance.
