Answer:

Option (C)

Explanation:

The non-renewable resources are defined as those resources that cannot be regenerated again and again. They are also known as conventional resources. For example, coal, oil, petroleum and natural gas. These are formed after million so years, acquiring a lot of time. These are very limited in amount and are very difficult to determine where they re exactly located.

In today's world, everything is mostly dependent on these non-renewable resources. The burning up of these fossil fuels releases a large amount of carbon that is harmful to the atmosphere and creates pollution.

Theses resources are obtained at an affordable price and are inexpensive, so these resources are more frequently used than renewable resources.

Thus, the correct answer is option (C).

Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1.38 m and finds that it makes 441

Tasya [4]

The period of a simple pendulum is given by:
$T=2 \pi \sqrt{ \frac{L}{g} }$
where L is the pendulum length, and g is the gravitational acceleration of the planet. Re-arranging the formula, we get:
$g= \frac{4 \pi^2}{T^2}L$ (1)

We already know the length of the pendulum, L=1.38 m, however we need to find its period of oscillation.

We know it makes N=441 oscillations in t=1090 s, therefore its frequency is
$f= \frac{N}{t}= \frac{441}{1090 s}=0.40 Hz$
And its period is the reciprocal of its frequency:
$T= \frac{1}{f}= \frac{1}{0.40 Hz}=2.47 s$

So now we can use eq.(1) to find the gravitational acceleration of the planet:
$g= \frac{4 \pi^2}{T^2}L = \frac{4 \pi^2}{(2.47 s)^2} (1.38 m) =8.92 m/s^2$

PLEASE ANSWER-Why are loose electrons needed for heat conduction?

dolphi86 [110]

Answer:

Why do metals conduct heat so well? The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.
