A 2kg object is dropped from a height 10m.Calculate the speed of the object after it has fallen 5m, assuming there is no resista
Ugo [173]

Answer:

10m/s

Explanation:

d=v_ot+\dfrac{1}{2}at^2

Since there is no initial velocity as the object is dropped, you can write the following equation:

5=\dfrac{1}{2}(10)t^2 \\\\1=t^2 \\\\t=1

Now that you know how long the fall took, you can use another physics equation to find the velocity at that point.

v_f=v_o+at

Since there once again is no initial velocity, you can rewrite this as:

v_f=at=(10)(1)=10m/s

Hope this helps!

Fofino [41]

Answer:

The correct answer is

right; fall

Explanation:

When there are changes in the costs of the factors of production, it can result in the supply curve shifting to the right or to the left. That means the quantity supplied at the given price has either increased or decreased, hence the supply curve shows the relationship between quantity supplied at a given price

Factors that can cause a shift in supply curve include, prices of imput materials, increased competition, technological advancement, social or natural factors and general expectations.

When the supply curve shifts right, that means increased in supply or more units are available at a given price, hence prices fall. However if the supply curve shifts left that means less goods are available at a given market price, hence prices of the commodities will rise

2. Define Lightning conductor. How does it work?
tresset_1 [31]

In Building, there are a host of protective devices that are installed to protect lives and properties, one of them is the Lightning Conductor that  a metal rod mounted on a structure and intended to protect the structure from a lightning strike. It works on the principle of induction

<h3>Principle of Operation of Lightning Conductor</h3>

The lightning conductor works on the principle of induction:

  • When a charged cloud passes by the building hosting the Lightning conductor, it gets a charge opposite to that of the cloud through the process of induction.
  • They are Typically made from copper material.

Most Lightening conductors are made from copper materials.
