Explain why fluids travel faster near the center of pipes and tubes than at the edges

Answers

Answer 1

Answer: I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.

Answers

Answer:

1.a) 1 kJ

1.b) 4 kJ

ratio 1:4

1.c) 4 times as before

2.a) 3.33 m/s2

Explanation:

1.a) bicycle's velocity =Displacement/time

=100/20 m/s

=5 m/s

bicycler's KE =1/2 *mass*(velocity)^2

=1/2*80*5^2

=1000 J = 1 kJ

1.b) bicycle's new velocity =200/20 m/s

=10 m/s

bicycler's new KE =1/2*80*10^2

=4000 J = 4 kJ

Ratio= KE 1 :KE new

= 1 :4

1.c) when bicycler's speed was doubled it increased the KE by 4 times (2^2). because In KE we consider the square of the speed , so the factor we increase the speed , the KE will get increased with the square value of it

ex : speed is triple the prior value , then the KE is as 3^2 times as before. that is 9 times

2.a) car acceleration = (20-0)/6 m/s2

= 3.33 m/s2

A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.
