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.

For every action, there is an equal and opposite reaction” is a definition of _________ ​
sveticcg [70]

Answer:

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

If a 4 Ω resistor, a 7 Ω resistor, and a 12 Ω resistor are connected in a series, which resistor has the most current in it?
sesenic [268]
<u>series </u> 
 current same to all resistors
 p.d  is divided to each resistors depending on their resistivity 
V = IR  the resistor which have more resistance (also resistivity) gain more p.d

<u>parallel
</u>  p.d  is same to all components
<u />  current is divided to each resistor depending on their resistivity
  I = V/R  more current flows through one with less resistance (also resistivity)

here as it is series connection,<u>current is same</u> to all resistors irrespective of their resistance

what is the thickness of the central portion of a thin conveying lens can be determined very accurately by using (a) vernier cal
beks73 [17]

Option B The thickness of the central portion of a thin conveying lens can be determined very accurately by using a micrometer screw gauge.

<h3>What can be measured using a micrometer screw gauge?</h3>

One micrometer of thickness can be measured with a micron micrometre screw gauge. A Use of Micrometer Screw Gauge as like example Upon turning the screw of the micrometer screw gauge four times, a 2 mm space is covered.

<h3>What purposes does a micrometer serve?</h3>

A tool known as a micrometer is used to measure solid objects’ lengths, thicknesses, and other dimensions precisely and linearly.

<h3>What is the micrometer screw gauge’s SI unit?</h3>

The SI symbol m is also known as a micron, which is an SI-derived unit of length equaling 1106 meters, where 106 is the SI standard prefix for the prefix “micro-.” A micrometer is one-millionth of a meter.

A vehicle that weights 400 n on the surface of the earth is traveling in outer space at a speed of 400 m/s. It can be stopped by applying a constant force of 20 n for <u>800 secs.</u>

Newtons 3 law whilst one object exerts pressure on any other object, the second object exerts a force on the first item this is identical in significance, but opposite in course; for each movement, there is an identical, but opposite response; referred to as the law of action-reaction.

You can use the equal formulation d = rt because of this distance equals the price instance's time. To solve for speed or rate use the components for pace, s = d/t this means that pace equals distance divided by way of time. To clear up for time use the components for time, t = d/s this means that time equals distance divided by way of velocity.
