The conversion factor can be used to change values from one unit to another.

<h3>What is conversion factor?</h3>

The conversion factor can be used to change values from one unit to another. We know that there are various units that could be used for the measurement of a quantity. The conversion factor would enable us to change the unit in which a value is given.

Without the conversion factor, a value in meters can not be expressed in inch or a values expressed in torr be given in bars or millimeter mercury for ease of computation.

This ability to change from one value to another has made the solution of mathematical problems much easier and  helps us to have a better grasp of the computational procedure that could be used in the calculation that we want to do for a particular of given problem.

Now the conversion factor is;

1 foot = 3281 kilometers

Hence;

159 feet = 159 * 3281

= 521679 kilometers

A 58.0 kg snow skier is on the top of 351 m high hill. After she has gone down a vertical distance of 142 m, what is her mechani
Nezavi [6.7K]

Answer:

Explanation:

Initially skier is at a height of 351 m . Her kinetic enery will be nil because she is at rest . Her potential energy will be calculated as follows

potential energy = mgh where m is mass , h is height and g is acceleration due to gravity

potential energy = 58 x 9.8 x 351

= 199508 .4 J

Total mehanical energy = potential energy + kinetic energy

= 199508.4 J

According to conservation of mechanical energy , at the height of 142 m also total mechanical energy will be same . At this height some potential energy will be converted into kinetic energy but total of potential and kinetic energy will be same.

A hovering mosquito is hit by a raindrop that is 50 times as massive and falling at 8.9 m/s , a typical raindrop speed. How fast
Ivahew [28]

Answer:

v =  8.72 m/s

Explanation:

To find the speed of the raindrop joint to the mosquito, you take into account the momentum conservation law for an inelastic collision. Before the collision the total momentum of raindrop and mosquito must be equal to the total momentum of both raindrop and mosquito after the collision.

m_1v_1+m_2v_2=(m_1+m_2)v       (1)

v1: speed of the mosquito before the collision= 0 m/s (it is at rest)

v2: speed of the raindrop before the collision = 8.9 m/s

m1: mass of the mosquito

m2: mass of the raindrop = 50m1 (50 time more massive that the mosquito)

v: speed of both raindrop and mosquito after the collision

You solve the equation (1) for v and replace the values of the rest of the parameters:

v=\frac{m_1v_1+m_2v_2}{m_1+m_2}=\frac{m_1v_1+50m_1v_2}{m_1+50m_1}\\\\v=\frac{0m/s+50(8.9m/s)}{51}=8.72\frac{m}{s}

hence, after the inelastic collision the speed of the raindrop andmosquito is 8.72 m/s
