Look at the data table and graph for the 50-coil electromagnet. With the 1.5 V battery, the electromagnet picked up an average o

Triss [41]

1) The ratio between the number of turns of the two electromagnets is 2

2) The ratio between the number of paper clips picked up is 2.2

Explanation:

1)

An electromagnet is a device consisting of a coil of wire wrapped around an iron core. Such a device is able to create a magnetic field, and in this problem this is used to attract and pick up the paper clips.

In this problem, we have two electromagnets:

- The first one has 50 turns

- The second one has 25 turns

Therefoore, the ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25-coil electromagnet is:

$\frac{N_1}{N_2}=\frac{50}{25}=2$

2)

The strength of the magnetic field produced by an electromagnet is directly proportional to the number of turns in the coil wrapped on the electromagnet:

$B\propto N$

This means that the electromagnet with more turns will produce a stronger magnetic field, and therefore it will be able to pickup more paper clips.

In this problem, in fact:

- The electromagnet with 50 turns can pick up 13 paper clips

- The electromagnet with 25 turns picks up 6 paper clips

Therefore, the ratio of the number of paper clips picked up is:

$\frac{p_1}{p_2}=\frac{13}{6}=2.2$

And we see that this ratio is approximately equal to the ratio of the number of turns, which is 2.

An iron weight, suspended by a string, is motionless. The tension in the string is 4.75 newtons. What is the mass of the iron we

kakasveta [241]

Since weight is motionless, net force is equal to zero.
According to Newton's 2nd law of motion,

T - mg = 0-----------(T = tension, mg = weight of mass)

4.75 = m x 9.8
m = 4.75/9.8

m = 0.48 kg.

Hope this helps\!

Technician A says that failure analysis will assist the technician in determining whether it is more cost effective to replace r

Jobisdone [24]

Answer:

The correct option is;

Technician A

Explanation:

Here we note failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.

However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.
