The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work pr

operly. Nikola Tesla saw this as an inefficient way to produce electricity. As a result, Tesla used the idea of the rotating magnetic field, which had been developed by François Arago, to invent the induction motor, which reverses automatically. How is this an example of a scientist applying creativity to solve a problem? Tesla investigated a new problem that no one had considered before. Tesla used another scientist’s research to help develop his own solution to a problem. Tesla designed a new experimental method for research. Tesla invented an entirely new concept to replace an inefficient design.

Because the pressure falls, water boils at a lower temperature with increasing altitude. Consequently, cake mixes and boiled egg
AlexFokin [52]

Answer:

1) The boiling point of water reduces by 3.28°C at 1,000 m above sea-level

2) The boiling point of water reduces by 6.56°C at 2,000 m above sea-level

Explanation:

The variation of the boiling point of water with elevation is given as follows

The boiling point reduces by 0.5°C for every 152.4 meter increase in elevation

At sea-level, the boiling point temperature of water = 100°C

1) At 1,000 m elevation, the boiling point temperature, T = 100 - (1,000/152.4) × 0.5 ≈ 96.72 °C

Therefore, the boiling point of water reduces by 100° - 96.72° = 3.28°C at 1,000 m above sea-level

2) At 2,000 m elevation, the boiling point temperature, T = 100 - (2,000/152.4) × 0.5 ≈ 93.44°C

The boiling point of water reduces by 100° - 93.44° = 6.56°C at 2,000 m above sea-level

What is a net force on an object that has a mass of 20.0 kg, an applied force of 100 n moving on a surface with a friction coeff
sergiy2304 [10]

The net force on the object as described is; 58.84N

Two forces acting on the object are;

  • The <em>applied force and the frictional force.</em>

In essence; the frictional force can be evaluated as;

  • Frictional force; = coefficient × Weight of object.

  • Frictional force = 0.21 × 20 × 9.8.

  • Frictional force = 41.16N

  • The Net force = Applied force - frictional force

  • Net force = 100 - 41.16N

Net Force = 58.84 N.
