The speed of the electron is 1.98×10⁸ m/s. Considering the electron has a total energy of 5.5×105ev.
The speed of an electron with a total energy of 5.5×10⁵ eV can be calculated using the relativistic energy-momentum equation: E² = (pc)² + (mc²)²
where E is the total energy of the electron, p is its momentum, m is its rest mass, and c is the speed of light.
Rearranging the equation to solve for the momentum, we get: p = sqrt(E² - (mc²)²)/c
Substituting the values, we get:
p = sqrt((5.5×10⁵ eV)² - (9.11×10⁻³¹ kg * (2.998×10⁸ m/s)²)²)/2.998×10⁸ m/s
p = 1.80×10⁻²⁰ kg·m/s
Finally, we can calculate the speed of the electron using the momentum:
v = p/m = (1.80×10⁻²⁰ kg·m/s) / 9.11×10⁻³¹ kg
v = 1.98×10⁸ m/s.

An object launched at 65 degrees from the horizontal would have the same range (distance travelled) as an object launched from? Write only the WHOLE number with no units (example: 65)
An object launched at 65° from the horizontal would have the same range (distance travelled) as an object launched at 25° from the horizontal.
The greatest range you can get when you launch a projectile is to aim it at 45° above the horizon. If you change that angle by something, then the range is shorter by the same amount if you increse OR decrease the angle by the same something.
65° = 45° plus 20°. So the range will be the same if you launch at an angle of (45° minus 20°). That's 25°.

e. 100 kg/m3
The density of a 2-cubic meter block of mass of 1000 kg is 500 kg/\(m^{3}\).
We use the word "density" to indicate how much space (or "volume") an object or substance occupies in relation to the amount of matter contained therein (its mass). Density can also be defined as the quantity of mass per unit of volume. A dense object is one that is both hefty and small. Density is a crucial concept because it allows us to predict which compounds will float and sink in liquids. The density of an object needs to be lower than the density of the liquid in order for it to float.
Density= \(\frac{Mass}{Volume}\)
= \(\frac{1000 kg}{2 cubic meter}\)
= 500 kg/\(m^{3}\)
So, The density of a 2-cubic meter block of mass 1000 kg is 500 kg/\(m^{3}\).

how will the gravitational force between the moon and a spacecraft change as the spacecraft nears the moon? it will increase. it will increase. it will repel the spacecraft. it will repel the spacecraft. it will decrease. it will decrease. it will remain the same.
As the spacecraft nears the moon, its gravity will increase.
This is because the gravitational force between objects is inversely proportional to their distances from each other.
The gravitational force between a spacecraft and moon will also increase as they get closer together due to tidal forces. Tidal forces are caused by differences in water levels at either side of an object and are strongest when two objects are close together (i.e., when they're orbiting).
Therefore, When a spacecraft is close to the moon, the gravitational force between it and the moon will increase.

The pressure due to the liquid on an object immersed in that liquid is 4500 Pa
The density of the liquid is 900 kg/m.
What is the depth of the object below the surface of the liquid ?
Answer:
The depth of the object below the surface of the liquid is 0.510 meters.
Explanation:
The hydrostatic pressure (\(P\)), measured in pascals, experimented by the object is directly proportional to density of the fluid (\(\rho\)), measured in kilograms per cubic meter, gravitational acceleration (\(g\)), measured in meters per square second, and depth of the object (\(h\)), measured in meters. That is:
\(P = \rho\cdot g \cdot h\) (1)
If we know that \(P = 4500\,Pa\), \(\rho = 900\,\frac{kg}{m^{3}}\) and \(g = 9.807\,\frac{m}{s^{2}}\), then the depth of the object is:
\(h = \frac{P}{\rho\cdot g}\)
\(h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}\)
\(h = 0.510\,m\)
The depth of the object below the surface of the liquid is 0.510 meters.
The depth of the object below the liquid's surface will be
"0.510 m".
Pressure and DensityAccording to the question,
Object immersed, P = 4500 Pa
Density of liquid, ρ = 900 kg/m³
Acceleration due to gravity, g = 9.8 m/s²
We know the relation,
→ Hydrostatic pressure (P) = ρ.g.h
or,
Depth will be:
→ h = \(\frac{P}{\rho .g}\)
By substituting the values,
= \(\frac{4500}{900\times 9.8}\)
= \(\frac{4500}{8820}\)
= 0.510 m
Thus the above answer is appropriate.

Rainbow images are captivating circular bands of colors formed when sunlight is refracted by water droplets, creating a beautiful display of nature's intricate light phenomena.
A rainbow image is a captivating natural phenomenon that occurs when sunlight is refracted, or bent, by water droplets in the atmosphere. It appears as a circular band of colors, typically red, orange, yellow, green, blue, indigo, and violet, arranged in a specific order.
The process begins when sunlight enters a raindrop and is split into its component colors due to the bending of light. As the light rays bounce off the inner surface of the droplet, they are further refracted and dispersed. When the dispersed light exits the droplet, it forms a circular arc in the sky, with the red color on the outer edge and the violet on the inner edge.
The vibrant colors of a rainbow image are a result of the varying wavelengths of light being separated and visible to our eyes. Rainbows can be observed after rain showers when sunlight breaks through the clouds, or they can be seen near waterfalls or misty areas. They are a beautiful reminder of the intricate nature of light and the wonders of the natural world.

what changes must a gas undergo to become a liquid?
The conversion of gas into liquid happens due to condensation.
Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. For example, condensation occurs when water vapour (gaseous form) in the air changes into liquid water when it comes in contact with a cooler surface. When the water in the air comes in contact with a cold surface, it condenses to form water droplets. The opposite of condensation is evaporation reaction.When temperature is increased and pressure is decreased, the gaseous state is converted into liquid state on this impact.

If observations had shown that the cosmic microwave background was perfectly smooth (rather than having very slight variations in temperature), then we would have no way to account for _________.
If observations had shown that the cosmic microwave background (CMB) was perfectly smooth, without any variations in temperature, then we would have no way to account for the formation of **large-scale structures** in the universe.
The slight temperature variations observed in the CMB, known as anisotropies, provide crucial evidence for the formation of structures such as galaxies, galaxy clusters, and cosmic filaments. These temperature fluctuations are a result of tiny density fluctuations in the early universe, imprinted shortly after the Big Bang during a period known as cosmic inflation.
These density fluctuations served as the seeds for the gravitational collapse of matter, leading to the formation of structures over billions of years. The regions of slightly higher density would have experienced stronger gravitational attraction, causing matter to accumulate and form clumps, while regions of slightly lower density would have become underdense regions.
If the CMB had been perfectly smooth with no variations, it would suggest a very uniform and homogeneous early universe, lacking the necessary initial conditions for the formation of structures. Our understanding of the evolution of the universe and the formation of galaxies and other large-scale structures would be significantly challenged without the observed temperature fluctuations in the CMB.

a 30 kg cart is travelling in a zero friction environment at a constant velocity of 5m/s. It's about to go up a very steep hill. How high will the cart be when the velocity changes to zero? PLEASE HELP
Answer:
1.27551m
Explanation:
This is a simple energy convertion problem. Since there is no friction, and assuming no air drag and other external factors, mechanical energy should be conserved in this system.
Thus, we get:
\(KE_{initial} + PE_{initial} = KE_{final} + PE_{final}\)
We also know that the gravitational potential energy is equal to mgh, while the KE can be calculated using \(\frac{1}{2}mv^2\)
One thing to note here, is that the final KE will be 0, as there is no velocity at the end. Furthermore, we also can set the initial PE as 0 as we are looking at relative height, and at the start it is at h=0.
\(KE_{initial} = PE_{final}\)
Plugging in:
\(\frac{1}{2}*30*5^2 = 30*9.8*h\)
Solving for h, we get 1.27551m

A boat takes 4 hours for travelling downstream from point A to point B and coming back to point A upstream. If the velocity of the stream is 2 Kmph and the speed of the boat in still water is 4 kmph, whit is the distance between A and B
Answer:
d = 6 km
Explanation:
In this case we have the relative speed of the boot changes, suppose that the boat and the river have the same direction when the boat goes from A to point B
vbr = vrt + vbt
vbr = 2 + 4
vbr = 6 km / h
v₁ = 6 km / h
velocity is constant
v₁ = d / t₁
t₁ = d / v₁
when the boat returns to the starting point the speed is both opposite
vbr = vbt - vrt
vbr = 4-2
vbr = 2 km / h
v₂ = 2 km / h
as the speed is constant
t₂ = d / v₂
they also indicate that the total time is 4 h
t₁ + t₂ = 4
we substitute
4 = d / v₁ + d / v₂
4 = d (1 / v₁ + 1 / v₂)
d = 4 / (1 / v₁ + 1 / v₂)
let's calculate
d = 4 / (1/6 + 1/2)
d = 4 / 0.6666 67
d = 6 km
According to the tachometer in the car the engine is rotating at 3500 RPM. Through what angle will this engine rotate each minute?
Answer:
Please look at the Explanation.
Explanation:
Assuming that the engine runs at a constant speed of 3500 revolutions per minute (RPM), we can calculate the angle through which it rotates each minute using the following steps:
Convert RPM to RPS (revolutions per second) by dividing by 60, since there are 60 seconds in a minute:
3500 RPM ÷ 60 = 58.33 RPS
Multiply RPS by 2π (the number of radians in a complete circle) to find the angle in radians per second:
58.33 RPS × 2π = 366.93 radians/second
Finally, multiply by 60 to convert radians per second to radians per minute:
366.93 radians/second × 60 seconds/minute = 22,015.8 radians/minute
Therefore, the engine rotates through an angle of approximately 22,015.8 radians each minute when it is running at 3500 RPM.
