Answer:

No matter, what there is always the same amount of energy in the universe!

Explanation:

That is essentially what the Law of Conservation of Energy states, however, this passage. Now I don't really have an in-depth view of what your requirements are, however, the idea is that energy cannot be destroyed or created; it can only be transformed. You have most likely learned about energy transformations: potential to kinetic (being a broad category). If potential energy goes down (for an object), kinetic energy for the object goes up. The Ramsey Box is essentially stating that the less you train, the more you will suck. The total mechanical energy stays the same, and goes up or down together. The less hard work, the more failure. The more hard work, the less failure. Comment if you want more info. I'm in 8th grade too btw:)

Stells [14]

Answer:

$-9.25 m/s^2$

Explanation:

The motion of the skater is a uniformly accelerated motion, so we can find the deceleration by using the following suvat equation:

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

In this problem, we have:

u = 19 m/s is the initial velocity of the skater

v = 18 m/s is the final velocity of the skater

s = 2.0 m is the displacement

Solving for a, we can find the acceleration:

$a=\frac{v^2-u^2}{2s}=\frac{18^2-19^2}{2(2.0)}=-9.25 m/s^2$

And the negative sign tells us that the acceleration is in the opposite direction to the motion (so, it is a deceleration)

Which statement is NOT true about "p" orbitals? Which statement is NOT true about "p" orbitals? A 3p orbital has a higher energy

ki77a [65]

Answer:

Option E is correction. None of the above.

Explanation:

( 1 ) A 3p orbital has more energy than 2p orbital and this is the reason it is away from the nucleus as compare to 2p orbital. Energy of the shells increases as their distance increases from the nucleus.

(2) p subshells are made up of three dumbbell-shaped orbitals

(3) There are three atomic orbitals in a p subshell. They are px, py, and pz.
