<h2>
The magnitude 24 (
) of the acceleration of the particle when the particle is not moving.</h2>
Explanation:
Given,
A particle moving along the x-axis has a position given by
m ........ (1)
To find, the magnitude ( ) of the acceleration of the particle when the particle is not moving = ?
Differentiating equation (1) w.r.t, 't', we get
⇒ 
....... (2)
⇒ 
⇒ 
⇒ t = 2 s
Again, differentiating equation (2) w.r.t, 't', we get
Put t = 2, we get
Thus, the magnitude 24 ( ) of the acceleration of the particle when the particle is not moving.
Heat always flows from a B. hotter object to a colder one.
Heat transfers always from hotter to colder.

Answer:
Einstein's general theory of relativity is the theory behind black holes has been tested with a wide range of experiments of which all confirm the predictions the theory makes. We cannot see black holes phenomena inside the event horizon, we do observe things outside this limit.
Black holes in binary star systems leave signs of their presence on neighboring star thats detected and the signs include X-ray emissions, accretion disks, and large orbit perturbations.
this is the evidence that astronomers and physicists have to show that the theory about black holes is correct.
I'm not sure tbh, but if it helps, heres a game that helped me understand bases acids and neutrals for chem in 8th grade! http://static.lawrencehallofscience.org/scienceview/scienceview.berkeley.edu/html/showcase/flash/jui... I know it looks cheesy, but it helps! Chem is something youll have until college, and it helps to learn about it. You can make drinks using acids, bases, and neutrals!
