What is magnification in compound microscope?The use of many lenses in a microscope is referred to as compounding. Another form of optical microscope is the compound microscope. Simple microscopes are the other kind of optical microscope. Simple and complex microscopes vary in that a simple microscope only requires one lens, but a compound microscope requires many lenses.
An tool used to see magnified pictures of tiny objects, such as cell structures on a glass slide, is a compound microscope or high-power microscope. Enlarging the apparent size is the process of magnification. This expansion is quantified by a mathematical quantity sometimes known as "magnification." Magnification often refers to scaling up graphics to view more detail and raise resolution.
When using a compound light microscope, the power of the objective lens, which can be 4x, 10x, or 40x, must be multiplied by the power of the eyepiece, which is commonly 10x, to determine the overall magnification.Consequently, a 10x eyepiece combined with a 40X objective lens will result in a 400X magnification. Now that the specimen can be seen with the unaided eye at a 400-fold higher magnification, minute features are made visible.
Given,
m = +750
mo = +150
a) total magnification, m = mo.me
me = m/mo = 750/150 = 5
Thus magnification of eyepiece is 5.
b) Total magnification = mo.me = 400 x 5 = 2000
Thus total magnification of objects having magnification 150 and 400 is 2000.

a uniform beam is suspended horizontally by two identical vertical springs that are attached between the ceiling and each end of the beam. the beam has mass 225 kg, and a 175-kg sack of gravel sits on the middle of it. the beam is oscillating in shm, with an amplitude of 40.0 cm and a frequency of 0.60 cycles/s.What is the frequency of the subsequent SHM of the beam?
1. What is the amplitude of the subsequent SHM of the beam?
2. If the gravel instead falls off when the beam has its maximum speed, what is the frequency of the subsequent SHM of the beam?
3. What is the amplitude of the subsequent SHM of the beam?
The frequency and amplitude of the SHM beam is 0.8 Hz and 0.098 m. The frequency of the SHM wave when gravel falls is 0.8 Hz and the amplitude of subsequent SHM beam is 0.4m.
(a) Mass of the spring = 225 Kg
Mass of the sack = 175 Kg
Amplitude of the beam = 40 cm = 0.40 m
Frequency of the beam = F = 0.60 cycles/s
The formula for frequency of oscillation =
= f = (1/2π) X √(k/m)
where, k = 2π²F²m
= k = 2 X (3.14)² X 0.6² X (225 + 175)
= k = 5685.37 N/m
Strength of the spring before gravels fall = x =
= x = mg / k
= x = [ (225 + 175 ) X 9.8 ] / 5685.37
= x = 0.689 m
But, the spring is stretched by the distance of x' which is expressed as,
= X = x - x'
= X = 0.689 - 0.40
= X = 0.289 m
Now, since we know that the gravel falls, thus frequency = f =
= f = (1/2π) X √(k/m)
= f= (1/ 2 X 3.14) X √ 5685.37 / 225
= f = 0.8 Hz
(b) Assuming that the spring is stretched, x = mg/k =
= x = (225 X 9.8) / 5685.37
= x = 0.3878 m
Thus, the amplitude of the sack = A = 0.3878 - 0.289
= A = 0.098 m
(c) If the gravel falls, the speed is maximum hence speed = s =
= s = A X √(k/m)
= s = 0.4 X √(5685.37/400)
= s = 1.508 m/s
The frequency = f' =
= f' = (1/2π) X √(k/m)
= f' = (1/2 X 2.14) X √(5685.37/225)
= f' = 0.8 Hz

the pulley is initially at rest. at 4.9 s what are (a) its angular acceleration and (b) its angular speed?
The pulley is initially at rest are:
a) The angular acceleration is 0 rad/s^2.
b) The angular speed is 0 rad/s.
Initially, the acceleration of the pulley is zero. As the pulley starts to move, the acceleration increases until it reaches its maximum value, which is determined by the magnitude of the force applied to it. As the pulley continues to move, the acceleration gradually decreases until it reaches zero again as the pulley comes to rest.
Angular acceleration is the rate at which the angular velocity of an object changes over time. It is usually expressed in terms of radians per second squared (rad/s2). Angular acceleration is caused by a torque being applied to an object and can be used to predict the angular velocity of a spinning object. Angular acceleration is a vector quantity, meaning it has both magnitude and direction.
Angular speed is the rate at which an object rotates or revolves around an axis. It is measured in terms of angle per unit of time and is usually expressed in radians per second (rad/s) or revolutions per second (rpm). Angular speed is related to linear speed, which is the distance traveled per unit of time. The angular speed can be calculated by taking the ratio of the linear speed and the radius of the circular path.

how are rotation curves of spiral galaxies determined beyond radii where starlight can be detected?
Rotation curves of spiral galaxies are a measure of the velocity of the stars and gas in the galaxy as a function of distance from the center. These curves are important for understanding the mass distribution of the galaxy, which in turn helps us understand the structure of the galaxy and its evolution.
In order to determine the rotation curves beyond the radii where starlight can be detected, we must use indirect methods. One of the most important indirect methods is the use of neutral hydrogen gas, which is typically found in the outer regions of galaxies. By measuring the Doppler shifts of the hydrogen gas using radio telescopes, we can determine the velocity of the gas as a function of distance. This allows us to trace the rotation curve out to much larger radii than just the starlight.
Another method for determining the rotation curves beyond the radii where starlight can be detected is to use gravitational lensing. This method relies on the fact that the gravity of a massive object, such as a spiral galaxy, can bend and focus the light from more distant objects. By measuring the distortions of the light from those distant objects, we can infer the mass distribution of the galaxy and thus its rotation curve.

in a lab experiment, a sensor is placed to detect the motion of an object relative to the sensor. the sensor was set up to identify the direction away from it as positive. a set of data including the velocity, and acceleration of the object at every 0.01s was recorded. if the values of both, velocity and acceleration, are negative, what statement below about the motion of the object is correct?
The statement below concerning the item's motion is true since the object was edging farther away from the sensor while slowing down.
What are the three categories of acceleration?The three main categories of accelerated movements are uniform, non-uniform, and average acceleration. When an item moves in a straight path with an increase in speed occurring at regular intervals of time, this motion is referred to as having uniform acceleration.
How do acceleration and velocity compare?Velocity is the rate at which displacement changes. The pace at which speed changes is known as acceleration. Because it consists of both magnitude and direction, velocity is a vector quantity. Since acceleration is only the rate at which velocity changes, it too is a vector quantity.

Three light-related phenomena are the subject of extensive research.
1) Rainfall's ability to disperse sunlight in the atmosphere.
2) The changing degrees of refraction of white light, which results in the construction of a rainbow arch.
3) The complete interior reflection of the raindrop. Refraction happens when light enters one medium and then exits another, producing our reaction.
Refraction, which is indicated by the light's bending or change in direction, can occur when electromagnetic energy in the form of visible light passes from one substance or medium to another.
Total internal reflection happens when light rays enter a right-angled glass prism at an angle of incidence larger than the critical angle.
