The true response is A. The greatest amount of solid particles that a stream can transport in a given amount of time is known as capacity.

The categorization of the sediment is based on their size. From smallest to largest in size, they may be divided into the following categories: clay, silt, sand, pebbles, cobble, and boulder.

Small sand grains between 0.2 mm and 0.5 mm are the particles in a stream that dissolve the most quickly. Any object that is smaller or larger needs more water moving past it in order to be degraded and entrained inside the flow.

Competence is a measure of a person's skill, whereas capacity is the greatest load of solid particles a river can move in a unit of time. The capability of a stream to move particles as per size rather than amount.

When light from infinite coming toward the lens of the telescope then this light is converge at the focal plane of the lens. This will image which is formed at the focal plane worked as an object for another lens of the telescope.

Now another lens made the final virtual image which is seen by the observer.

So here in this whole process the main working of Telescope is to form the image of a distant object near to the eye of an observer. So the light coming from the infinite distance is collected together and then a bright image is formed by that light so that observer is able to see the image clearly

Explanation:

The Doppler effect can be used to measure radial motion, which refers to the motion of objects along the line of sight. In the context of stars, the Doppler effect allows astronomers to determine the radial velocity of stars, which is their motion towards or away from the observer.

When a star moves towards an observer, the observed wavelengths of the light emitted by the star are compressed, resulting in a blue shift. On the other hand, when a star moves away from an observer, the observed wavelengths are stretched, leading to a red shift. By analyzing the shift in the wavelengths of the star's spectral lines, astronomers can determine the star's radial velocity.

The Doppler effect is a valuable tool for studying the motion of stars, including the motion of binary star systems, the rotation of stars, and even the motion of galaxies. It allows astronomers to investigate the dynamics and kinematics of celestial objects and gain insights into their behavior and interactions.

Answer:

Air resistance, also known as drag, is a force that is caused by air, the force acts in the opposite direction to an object moving through the air. It is where air particles hit the front of the object slowing it down. The more surface area, the more air particles hit it and the greater the resistance.

The focal length of the converging lens is approximately equal to 3113 cm.

The magnification produced by a converging lens is found to be 3.1 for an object placed 18 cm from the lens.

The focal length of the lens can be calculated using the formula for magnification provided below:

Magnification = Image height / Object height

Magnification produced by the lens = 3.1

The object height can be assumed as 1 since it is not given.

Therefore, the image height will be equal to the magnification.

Image height = Magnification = 3.1

The distance of the object from the lens is given as 18 cm.

The focal length of the lens can be calculated using the formula provided below:

1 / f = 1 / v - 1 / u

Where,

f is the focal length of the lens

u is the distance of the object from the lens

v is the distance of the image from the lens

The image is formed on the opposite side of the lens from the object.

Therefore, the image distance will be negative.

u = -18 cm

v = image distance = magnification * object distancev = 3.1 * 18 cm

v = 55.8 cm

Substituting the values of u and v in the formula provided above, we get:

1 / f = 1 / 55.8 - (-1 / 18)

1 / f = 0.0179

f = 55.8 cm / 0.0179

f = 3112.85 cm

What is friction?

The force that prevents one solid item from moving over another is known as friction. Static friction, sliding friction, rolling friction, and fluid friction are the four major categories of friction. Two surfaces that come into contact and slide against one another produce frictional energy. Surface roughness and the quantity of force pressing them together have the biggest an impact on these forces.

The angle of friction is the product of normal reaction and limiting friction with the normal reaction. The tangent of the friction angle is equivalent to the coefficient of static friction.

0= Usmgcos(ø) - mg*sin(ø)

mgsin(ø) = Usmg*cos(ø)

Option A is correct, conduction is the method by which the primary heat transfer mechanism does one end of a steel rod becomes hot when the other end is placed in a flame

Conduction is the manner with the aid of which heat is transferred from the warmer quit to the colder cease of an item. The ability of the item to behave warmth is known as its thermal conductivity and is denoted as k.

Heat spontaneously flows along a temperature gradient. for example, warmth is performed from the hotplate of an electric range to the bottom of a saucepan in contact with it. in the absence of an opposing external riding energy source, inside a frame or between bodies, temperature differences decay through the years, and thermal equilibrium is approached, temperature turning more uniform.

In conduction, the warmth glide within and via the body itself. In evaluation, in a warmness switch by using thermal radiation, the transfer is regular between bodies, which may be separated spatially. warmness also can be transferred by using a combination of conduction and radiation. In solids, conduction is mediated by way of the combination of vibrations and collisions of molecules, propagation and collisions of phonons, and diffusion and collisions of loose electrons. In gases and drinks, conduction is due to the collisions and diffusion of molecules at some stage in their random movement.

Photons in this context do not collide with one another, and so warmness delivery by using electromagnetic radiation is conceptually awesome from heat conduction by way of microscopic diffusion and collisions of cloth particles and phonons. but the difference is frequently now not easily found except the fabric is semi-transparent.

The quantity with the same units as force times time (ft) and dimensions of MLT^(-1) is momentum.

Momentum is defined as the product of an object's mass and its velocity. Its units in the SI system are kilogram meters per second (kg m/s).

To see why momentum has the same units as force times time, we can use the definition of force, which is the rate of change of momentum.

F = dp/dt

where F is force, p is momentum, and t is time. Rearranging this equation, we get:

F * t = dp

where F * t is force times time (ft) and dp is the change in momentum. Therefore, force times time has the same units as momentum, which is MLT^(-1).

The Coriolis effect is a condition which causes a hurricane to rotate in a particular direction. Thus, the correct option is B.

Hurricanes are the enormous storms which come with a rotating wind speed of about 74 miles per hour. The rotating wind that swirls across the warm water of the tropics and also comes with a terrifying force.

The Coriolis force is an inertial or the fictitious force, which acts on the objects which are in motion within a frame of reference that rotates them with respect to an inertial frame. In a reference frame, with the clockwise rotation, the force acts to the left of the motion of the object. Whereas, in one with anticlockwise or counterclockwise rotation, the force acts to the right of the object. The deflection of an object due to this Coriolis force is called as the Coriolis effect.

Therefore, the correct option is B.

Electric field lines can be considered similar to pressure lines where the electric potential would be similar to a voltage.

One can draw pressure lines in a hose from a positive voltage to a voltage of zero at the exit of the hose.

If one were to reverse the voltage the field lines would also be reversed.

Note: at 100 lbs force at a faucet and a hose length of 10 m one would have a force drop of 100 lbs / 10 m of 10 lbs / m in the hose.

Practically one would never have an exit force of 0 lbs or no water would flow - but one can see the similarities

The answer is D.) 90

Explanation:

the electromagnetic wave is a transverse wave. the electric field makes an angle of 90° with the magnetic field. both these fields, in turn, make an angle of 90° with the direction of movement of the wave.

The correct answer is 378000 km.

The speed of light is the rate at which light waves move through distinct substances. In instance, it has now been established that the speed of light in a vacuum is 299,792,458 metres per second.

Using the equation

distance = speed × time,

the total distance travelled is calculated.

Consequently, the overall distance travelled is

Distance = ( 3.00 × 10^8 m/s ) ( 2.52 )

= 756000000 m

The total distance travelled divided by two determines the distance between the Earth and the Moon.

Distance between earth to moon = 756000000/2

= 378000000 meters

= 378000 km.

Approximately 384 thousand kilometres separate the Earth and the Moon.
