<u>Answer:</u>

The correct answer option is 'lower energy level'.

<u>Explanation:</u>

An electron in the first energy level of the electron cloud has lower energy as an electron in the third energy level.

Electrons in the first orbital (s) have the lowest energy of any electrons in that principal energy level.  

Difference between the energy levels is caused when two electrons in a single orbital spin in opposite directions on their axes.

Describe what happens when the rock on the top of a hill is pushed.
Zigmanuir [339]

Answer:

The precise point is that gravitational energy is potential energy unless it makes something move, and then the energy is converted to kinetic energy, no work can be done. So a big rock at the top of a hill has no kinetic energy. Its only when it rolls down that work is done, and this can be converted to useful energy.

A 650-kg elevator starts from rest. It moves upward for 3.00 s with constant acceleration until it reaches its cruis- ing speed
Nataly_w [17]

Answer: P=5573.43\ W

Explanation:

Given

Mass of the elevator is M=650\ kg\\\

Time period of ascension t=3\ s

cruising speed v=1.75\ m/s

Distance moved by elevator during this time

Suppose Elevator starts from rest

\Rightarrow v=u+at\\\Rightarrow 1.75=0+a(3)\\\Rightarrow a=0.583\ s

Distance moved

\Rightarrow h=ut+0.5at^2\\\Rightarrow h=0+0.5\times 0.5833\times (3)^2\\\Rightarrow h=2.62\ m

Gain in Potential Energy is

\Rightarrow E=mgh\\\Rightarrow E=650\times 9.8\times 2.62\\\Rightarrow E=16,720.3\ N

Average power during this period is

\Rightarrow P=\dfrac{E}{t}\\\\\Rightarrow P=\dfrac{16,720.3}{3}\\\\\Rightarrow P=5573.43\ W

Alcohol consumption slows people's reaction times. In a controlled government test, it takes a certain driver 0.320 s to hit the
harina [27]

Answer:

\triangle d=21.726m

Explanation:

From the question we are told that:

Unimpaired time to hit break t_i=0.320s

Drunk time t=1s

Initial Velocity v=110km/h

Generally the equation for Average velocity is mathematically given by

V_{avg}=\frac{\triangle d}{\triangle t}

Therefore

\triangle d=v.dt

\triangle d=31.95*(1-0.32)

\triangle d=21.726m
