The speed of the car in miles per hour and meters per second is 2.2369

The first person to calculate speed by accounting for both the distance travelled and the amount of time required was the Italian physicist Galileo Galilei. Galileo described speed as the distance travelled in a unit of time.

The speed of anything indicates how quickly it is moving. Miles per hour (mph), kilometres per hour (km/h), and metres per second (m/s) are the three most used speed measurement units (mph).

A speedometer is the most effective tool for demonstrating instantaneous speed. Another method to state the speed of light is as 186,282 miles per second. The speed of sound in dry air is 343.2 metres per second. The term "escape velocity" refers to the speed necessary to escape the gravitational pull of the Earth.

Distance, which is independent of direction, is the length between two points or things. Distance only considers the total magnitude and disregards the start and finish positions because it is a scalar property. Distance can only have a positive or zero value because it is a scalar attribute; it cannot be negative. The meter (m) is the most widely used unit of measurement for distance, though kilometers (km) can also be used to express longer distances and centimeters (cm) or millimeters can be used to express shorter distances (mm).

Moon Illusion is an Optical Phenomenon. This occurs because when the moon is near the horizon, Earthly things that resemble the moon on your retina generate a misunderstanding or inaccurate perception of distance and size.

The brain interprets the low moon as being bigger since it is lower in the sky than the higher moon. The mechanism behind size-distance perception in everyday life, which transforms planar pictures that fall on the retina into a perception of hard objects moving in space, is related to the moon illusion.

What happens when the mechanism acts in an uncommon circumstance is what causes the moon illusion. In typical perception, the angular size of the light image stimulating our eyes expands or shrinks as rigid objects move in depth (distance).

The sense of hard objects with shifting depth perception is produced naturally by the brain in response to these changing stimuli. The ground and horizon make the moon appear comparatively close when it is close to the horizon.

Due to the moon's shifting apparent position in depth while the light stimulus stays constant, the moon appears extraordinarily huge due to the brain's size-distance mechanism.

Weight of the crate = 20 N

Length of the ramp = 3 m

Inclination of the ramp with horizontal = 30°

The friction between the ramp and the crate = 6 N

Potential energy of the crate at the top = 20 * 3 sin 30° = 30 J

Energy lost due to friction = 6 N* 3 m = 18 J

Let the speed of the crate at the bottom be v.

Assuming that 200 Mev of energy is released per fission of u235 , the mass of that undergoes fission reactor of power 1MW will be approximately will be the correct option is a i.e. 10^-2g.

The mass of the material that undergoes fission in a reactor with a power of 1 MW, you need to know the number of fissions that occur per second in the fission reactor. The power of a reactor is the rate at which energy is released by the fission reactions taking place inside it. The energy released per fission of uranium-235 is 200 MeV.

The relationship between power, energy, and time is given by the equation:

Power = Energy / Time

Rearranging this equation to solve for the number of fissions per second gives:

Number of fissions/second = Power / (Energy/fission)

Putting the values from the problem gives:

Number of fissions/second = 1 MW / (200 MeV/fission) = 5 x 10^22 fissions/second

Since the mass of uranium-235 is approximately 235.04 g/mol, the mass of the material that undergoes fission in the reactor is approximately:

Mass = (Number of fissions/second) x (235.04 g/mol) / (6.022 x 10^23 fissions/mol) = 3.93 x 10^-2 g

So, the mass of the material that undergoes fission in the reactor is approximately 3.93 x 10^-2 g, which corresponds to the answer choice "a. 10^-2g".

The time can be calculated as follows:

t = √2d/g

The rotational inertia of a body about a given axis is a measure of the body's resistance to changes in its rotational motion. It is given by the formula I = ∑m*r^2, where m is the mass of each particle in the body, r is the distance of each particle from the axis of rotation, and the sum is taken over all particles in the body.

In this case, the body is a flat circular disk with a mass of 3.00 kilograms and a radius of 70.0 centimeters. The axis of rotation is the vertical wire attached to the center of the disk. To find the rotational inertia of the disk about the wire, we need to calculate the sum of m*r^2 for all the particles in the disk.

Since the disk is uniform, all the particles in the disk have the same mass. Therefore, we can simplify the formula for rotational inertia to I = mR^2, where m is the mass of the disk and R is the radius of the disk. Plugging in the values for m and R, we get

This arrangement of charge creates a permanent dipole moment across the molecule, which is a result of the arrangement of the polar bonds and the molecular structure.

There was a lot of uncertainty about the universe's expansion rate before the Hubble telescope was launched. This value is required to calculate the universe's age, estimate its evolution over billions of years, and comprehend the forces that drive it. Astronomers were initially ecstatic when the expansion estimate was reduced to 10% accuracy. They are now approaching one percent accuracy after much perseverance and precise observations.

The cosmic clock can be rewound and the age of the universe calculated by precisely determining the expansion rate, known as the Hubble constant. However, Edwin Hubble's estimates of the universe's expansion implied that it was younger than the Earth and Sun. As a result, Hubble concluded that the redshift phenomenon was a previously unknown property of space rather than a measurement of true space velocity. Redshift was later discovered to be a result of the expansion of space itself, as predicted by Einstein's theory of special relativity.
