A hydrogen atom has a diameter of about 12.7 nm, express this diameter in centimeters.
Andrej [43]
1 meter = 1e9 nm
To get meters, divide nanometers by 1e9: 9.95nm / 1x10^9 = 9.95x10^-9 meters
Answer: 9.95e-9 meters

Which jovian planet should have the most extreme seasonal changes? a. Saturn b. Neptune c. Jupiter d. Uranus
Maksim231197 [3]

Answer:

D). Uranus.

Explanation:

Jovian planets are described as the planets which are giant balls of gases and located farthest from the sun which primarily include Jupiter, Saturn, Uranus, and Neptune.

As per the question, 'Uranus' is the jovian planet that would have the most extreme seasonal changes as its tilted axis leads each season to last for about 1/4 part of its 84 years orbit. The strong tilted axis encourages extreme changes in the season on Uranus. Thus, <u>option D</u> is the correct answer.

How does the equivalence principle lead us to suspect that spacetime might be curved?
Dafna11 [192]

Answer:

To understand Einstein's thought processes,

imagine yourself in the sealed box, being accelerated through interplanetary

space at 9.8m/s^2. You grab the flashlight that you keep on the bedside

table and shine a beam of light perpendicular to the acceleration vector. Since the box is accelerating upward, the path of the light beam

will appear to you to be bent downward, as the floor of the box rushes up

to meet the photons. However, thanks to the equivalence principle, we can

replace the accelerated box with a stationary box experiencing a constant gravitational acceleration. Since there's no way to distinguish between these

two cases, we are led to the conclusion that the paths of photons will be

curved downward in the presence of a gravitational field. Gravity affects

photons, Einstein concluded, even though they have no mass. Contemplating  the curved path of the light beam.

Fermat's principle, which states that

light travels between two points along a path which minimizes the travel time  required. In a vacuum, where the speed of light is constant, this translates  into the requirement that light takes the shortest path between two points.  In Euclidean, or flat, space, the shortest path between two points is a straight  line. However, in the presence of gravity, the path taken by light is not a  straight line. Thus, Einstein concluded, space is not Euclidean.  The presence of mass, in Einstein's view, causes space to be curved.

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s
Veseljchak [2.6K]

Answer:

v_{avg} = 0

Explanation:

The object is moving to and fro about its mean position

and the equation for its displacement is given as

s = 5 sin(\pi t) + 5 cos(\pi t)

now in one complete time period we know that the the object will complete its one oscillation

So the change in the position of the object in one complete time period will be ZERO

so here we can say that

v_{avg} = \frac{displacement}{time}

since change in position is zero

so displacement = 0

v_{avg} = 0
