Harappa was the earliest city discovered in India.

Oligarchy is a form of government in which the power rests with the small group of people.

One atomic mass unit (AMU) is equal to the one-twelfth the mass of one carbon-12 atom.

It is launched vertically with an initial speed of 110 ft/sec.

It will reach maximum height when the speed drops to 0.

Vo=110 feet per second 

ho=2 feet 

So, h(t) = -16t^2 +110t +2 

Take the derivative: h'(t) = 110 -32t 

The maximum height will be at the inflection when the derivative crosses the x-axis, then h'(t)=0. 

So, set h'(t)=0 and solve for t: 

0 = 110 -32t 

-110 = -32t 

t=3.4375 

t=3.44 seconds.

Allotropes are the different physical forms of an element. Here in the given options, diamond and graphite are the pair of allotropes of carbon.

Some more examples are Molecular oxygen and ozone are pair of allotropes, Black and red phosphorous are also pairs of allotropes.

Metamorphism is the method of changing the structure of a rock by using heat and temperature.

Hence, for this to happen the parent rock must be in solid form only. Therefore, option C) is true.
