Answer:

Darwin's theory of natural selection lacked an adequate account of ... Darwinian principles now play a greater role in biology than ever before, .... Sadly, even if Mendel had lived to see the rediscovery of his work, he probably .... evolutionary forces are acting, a genetic equivalent to Galileo's law of inertia.

An object of mass 20g taken at a height of 2m above the ground. Which type of energy is possessed by the object at this height ?

In-s [12.5K]

<h3><u>Given</u> </h3>

Mass of an object is $\bf\red{20 g}$
Height of the body is $\bf\green{2 m}$

Value of the energy

<h3><u>Solution</u></h3>

${\purple {\underline{\boxed{\sf{ Potential\: Energy \:=\: mgh}}}}}$

Where,

$\sf\red{m}$ = Mass
$\sf\green{g}$ = Gravity
$\sf\blue{h}$ = Height

Now, Converting gram to kg

$\longrightarrow\:$ 1000g = 1kg

$\longrightarrow\:$ 20g = $\sf\dfrac{20}{1000}$

$\longrightarrow\:$ = 0.02 kg

According to the question

$\sf\red{Mass \:= \:0.02 kg}$

$\sf\green{Gravitational \;force \:= \;10 m/s^{2}}$

$\sf\purple{Height\: =\: 2 m}$

Putting these values

$\to\:$ Potential Energy = mgh

$\to\:$ Potential Energy = 0.02 × 10 × 2

$\to\:$ Potential Energy = 0.2 × 2

$\to\:$ Potential Energy = $\bf\pink{0.4\:joules}$

Why does a shirt appear white outside on a sunny day?

Maru [420]

The shirt absorbs the sunlight, so it appears white. All the light is reflected, so the shirt appears white. The sunlight refracts when it hits the shirt, so the shirt appears white.
