1. A 6-volt battery produces a current of 0.5 amps. What is the power in the circuit?

Answer:

0.75 grams

Explanation:

Today we have 6 grams

In 30 years, 3 grams remain

In 60 years 1.5 grams remain

in 90 years 0.75 grams remain

mathematically It would look like this

m = 6(0.5⁽ⁿ/³⁰⁾) where n is number of years

Researchers believe that sleep helps strengthen and enhance long-term memory function. Hence, option B is correct.

Meditation could be thought of as a series of practices that encourage enhanced awareness and focused attention. Meditation is a different way to change awareness that has been shown to have several benefits for psychological well-being.

To feel refreshed and alert when you get up, sleep is a crucial process that allows your body and mind to heal. The body needs adequate sleep to remain healthy and free of disease. Without enough sleep, the brain cannot work efficiently. This may affect your ability to concentrate, think clearly, and process memories.

That's the reason researchers believe that sleep help in enhancing longer memory function.

Hi there!

We can use the conservation of energy:

Ei = Ef

The initial energy involves kinetic energy while the final energy involves maximum elastic potential energy, so:

1/2mv² = 1/2kx²

We can cancel out the 1/2s for ease of solving:

mv² = kx²

Plug in given values to solve for x:

√(mv²/k) = x

√(5.7)(12²)/(150)) = x

x = 2.339 m

Hollywood studios get in trouble for a lack of diversity in their casting decisions. The true statement about this computational model is that it will be effective and efficient at eliminating bais from casting.

Option 1 is correct.

The lack of diversity in Hollywood studios casting decisions results in the inability to select and choose the right actors for a specified role play.

The use of a computational model makes use of a computer program that studies and compares the prospective actors to famous ones and chooses prospective actors that are most similar to famous ones.

This is the best result to can be achieved and derived in making decisions in the diversity of casting because the computational model provides actors that are most effective and efficient thereby elimination the bias from casting decisions. This model is objective and it's not based on emotional decisions, unlike people.

Explanation:

It is given that,

Resistance, R = 20 ohms

Voltage of the battery, V = 10 V

We can find current flowing through the circuit using Ohm's law as follows :

V = IR

\begin{gathered}I=\dfrac{V}{R}\\\\I=\dfrac{10}{20}\\\\I=0.5\ A\end{gathered}I=RVI=2010I=0.5 A

It can be seen from the Ohm's law, that the current is directly proportional to the voltage. It means that if the battery is replaced by a battery that provides a larger voltage, the current through the circuit will be more than 0.5 A i.e. it increases

The water from head of 20m or above is brought in open or closed conduit. Traditionally wooden blades are used as turbine on which water jets are strike upon, jets rotates the bigger wheel mounted on smaller wheel. There is continuos feed of grains in between grinds into finer particles.

Answer:

Explanation:

100 kph = 27.8 m/s

80 kph = 22.2 m/s

v² = u² + 2as

a = (v² - u²) / 2s

a = (22.2² - 27.8²) / (2(88))

a = -1.578282828...

a = -1.58 m/s²

t negative sign means the acceleration opposes the initial velocity.

t = Δv/a

t = (22.2 - 27.8) / -1.57828

t = 3.52 s

The force applied to the submerged rubber duck is 4.9 N.

The density of the rubber duck is calculated as follows;

ρ = S.G x density of water

ρ = 0.2 x 1000 kg/m³

ρ = 200 kg/m³

F = mg = (ρV)g

F = (200 x 0.0025) x 9.8

F = 4.9 N

1.  The galaxies are moving away from each other.

2.  There is a large amount of weak background radiation in the universe

3. The temperature of the universe has cooled over time

The Big Bang model says that initially the universe was born from a great initial explosion about 14 10⁹ years ago, with this idea several facts arise:

Let's apply these ideas to the different questions, to find the correct answers.

1) What phrase about galaxies provides evidence of the expansion of the universe proposed by the Big Bang

the correct answer is:

As there is no friction, the initial forces create a speed in the galaxies, therefore they must move away from each other at this speed

2) What phrases give evidence of the expansion of the universe

the correct answer is:

3) What evidence of expansion

In conclusion with the characteristics of the Big Bang we can find the correct answers for the different questions are:

Despite being the same temperature, the swimming pool is a much larger thermal energy store than the beaker of water.

Thermal energy is the energy contained within a system that controls its temperature. The flow of thermal energy is defined as heat.

Thermodynamics is a branch of physics that deals with how heat is transferred between different systems and how work is done in the process.

Thermal energy sources include natural gas, coal, and oil, as well as solar, heat pump electric, and geothermal heat.

A swimming pool and a beaker of water can both be the same temperature.

Despite being the same temperature, the swimming pool contains significantly more thermal energy than the beaker of water. A heated swimming pool's thermal store contains a lot of energy.

Thus, If a pool and a cup of water had the same temperature, then swimming pool has a much larger thermal energy.
