A 10,000J battery is depleted in 2h. What power consumption is this? *

Physics

Tomtit [17]3 years ago

Answer:

P = 1.4 W

Explanation:

Given that,

The work done or the energy of the battery, E = 10,000 J

Time, t = 2 h

We need to find the power consumption. Let it is P. Power is the rate of doing work. So,

P=\dfrac{W}{t}\\\\P=\dfrac{10,000}{2\times 3600}\\\\P=1.38\ W

or

P = 1.4 W

So, the power of the battery is 1.4 W.

The right-hand rule predicts the direction of the force on a positively charged object moving in a gravitational field true fals
eimsori [14]
The statement above is FALSE.
The right hand rule is used in physics to predict the direction of the force on a charged object moving in a MAGNETIC FIELD. The right hand rule is used to relate the relationship between the magnetic field and the forces that are exerted on the moving objects in the field. Using the right hand rule, for a positively charged object that is moving in an electric field, the pointer finger will point in the direction the charged object is moving, the middle finger will point in the direction of the magnetic field and the thumb will point in the direction of the magnetic force that is pushing the charged object.

Explain one recent idea that scientists have proposed for how the universe began. Consider the big bounce theory or the multiver
aliya0001 [1]

The most widely accepted theory about the universe is the big bang theory.

<h3>What is big bounce theory?</h3>

The Big Bounce theory refers to the universe that is expanding and contracting, move back and forth in a big-picture timeline. The Big Bang theory was happened about 13.8 billion years ago when the universe began as a tiny, dense, ball that exploded. Many astronomers use the Big Bang theory to show how the universe began. But what caused this explosion in the first thing that is still a mystery. It has passed through many stages, which can be considered cosmological theories. The flat Earth, the geocentric model, heliocentricity, galactic centricity, the Big Bang, and the Inflationary Big Bang. In the Big Bounce theory, the universe is expanding and contracting, seesawing back and forth in a massively big-picture timeline more specific theory called "Big Bounce" theory proposes that the universe could collapse to the state where it is first started and then initiate another Big Bang.

So we can conclude that The Big Bang theory says that the universe came into being from a single more than 13 billion years ago.

Which two pieces of evidence most directly support the idea that the universe is expanding from one original point?
Goryan [66]

Answer:

it is option 3

Explanation:

because as red shift occurs when object in a space is far from us, so many of the stars we know will be seen in red shift because they are far from us by 20 years the most of the starts we see will be in red shift
