If a pendulum clock keeps perfect time at the base of a mountain, will it also keep perfect time when it is moved to the tip of
vazorg [7]

Answer:

No

Explanation:

The period of a pendulum is given by

T=2\pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration due to gravity

We see that the period of the pendulum depends on the value of g. However, the value of the gravitational acceleration is different at different locations on Earth. In particular, at the top of the mountain the value of g is slightly lower than the value of g at the base of the mountain; in fact, g is given by

g=\frac{GM}{r^2}

where

G is the gravitational constant

M is the Earth's mass

r is the distance from the Earth's center

so since r is greater at the top of the mountain, g is lower, and therefore the period of the pendulum will be slightly longer.

The velocity of a particle traveling in a straight line is given by v = (6t - 3t²) m/s, where t is in seconds. If s = 0 when t =
qaws [65]

Answer

given,

v = (6 t - 3 t²) m/s

we know,

v = \dfrac{dx}{dt}

a = \dfrac{dv}{dt}

position of the particle

dx = v dt

integrating both side

\int dx = (6t - 3 t^2)\int dt

 x = 3 t² - t³

Position of the particle at t= 3 s

 x = 3  x 3² - 3³

 x = 0 m

now, particle’s deceleration

a = \dfrac{dv}{dt}

a = \dfrac{d}{dt}(6t - 3 t^2)

  a = 6 - 6 t

at t= 3 s

    a = 6 - 6 x 3

    a = -12 m/s²

distance traveled by the particle

  x = 3 t² - t³

at t = 0 x = 0

   t = 1 s   , x = 3 (1)² - 1³ = 2 m

   t = 2 s  ,  x = 3(2)² - 2³ = 4 m

   t = 3 s ,   x =  0 m

total distance traveled by the particle

D = distance in 0-1 s + distance in 1 -2 s + distance in 2 -3 s

D = 2 + 4 + 2 = 8 m

average speed of the particle

v_{avg} = \dfrac{distance}{time}

v_{avg} = \dfrac{8}{3}

v_{avg} =2.67\ m/s

Does the universe need explaining or can it just 'be' there?
Naddik [55]

Recently, We've been discussing this specific topic in my RS class. So, there are many theories to explain the existence of the world such as the Big Bang, Evolution or the Creation story.

Although these are three different ideas, they can still be related or interconnected with one another in some way. For example, George Lemaintre's Big Bang explanation can be linked with the Creation story in ways such as God being present at the Big Bang or even God being the one to allow the Big Bang occur.

Furthermore, God might have created us as apes or monkeys then we evolved to become humans.

In conclusion, the universe couldn't have come to pass just like that, they're must be Scientific or Theological truths to back this up. The only thing is that people have their unique beliefs, according to their religion, culture and childhood background.
