a jeweler's eyepiece generates magnifications of 20x. what is the size of the image of a 0.5mm gem?

Answers

Answer 1

The magnification produced by the lens of a 0.5 mm gem is 10mm.

The magnification of a lens is calculated in terms of the ratio of image height to object height. It is also expressed as a ration of image distance and object distance.

Magnification of lens = image height / object height  = image distance / object distance.

M = [tex]h^{'[/tex]/ h = v/u

Magnification of concave lens is negative and of convex lens is positive.

In the given question,

M = 20

h = 0.5 mm

We have to find size of image, [tex]h^{'[/tex] = ?

using magnification formula

m = h'/h

20 = h'/0.5

h' = 20× 0.5 =10 mm

A stream is 30. Meters wide and its current flows southward at 1. 5 meters per second. A toy boat is launched with a velocity of 2. 0 meters per second eastward from the west bank of the stream. How much time is required for the boat to reach the opposite bank of the stream?.

Answers

The time required for the toy boat to reach the opposite bank of the stream is 20 seconds.

To solve this problem, you need to use the concept of vector addition to find the net velocity of the toy boat relative to the ground. The net velocity of the toy boat is equal to the velocity of the current plus the velocity of the toy boat relative to the current.

The velocity of the current is 1.5 meters per second southward, and the velocity of the toy boat is 2.0 meters per second eastward. When these velocities are added vectorially, the resulting net velocity is 2.6 meters per second at an angle of 63.4 degrees east of south.

To find the time required for the toy boat to reach the opposite bank of the stream, you can use the distance traveled and the speed to calculate the time using the equation t = d/s, where t is the time, d is the distance, and s is the speed.

The distance traveled is 30 meters (the width of the stream), and the speed is 2.6 meters per second. Plugging these values into the equation gives you a time of t = 30 meters / 2.6 meters per second = 11.54 seconds. Rounding up to the nearest whole number gives you a time of 20 seconds.

Answers

The ball's change in momentum on the bounce will be "0.308 kg.m/s."

How does the momentum of the ball change when it bounces?

Since linear momentum is mv, it varies with each bounce by the same quantity, r = R. For instance, if a ball bounced 80% of its height each time, it would lose 20% of its energy.

Velocity and Motion

The answer is that the mass of a baseball is m = 0.140 m.

-1.20 m/s is the downward speed.

Upward speed, v "= 1 m/s

Since we are aware of the momentum, P = mv

The force acting downward is: = mv'

When the data are put together, Pv = 0.140 (-1.20) Pv = -0.168 kg.m/s

The forward motion is now: = mv "Pv = 0.140 kg/s/s Pv = 0.140 kg/s/s

Therefore, the modification will be: = 0.140 - (-0.168)

A car starts at rest and travels 100 m in 5 seconds. What is the car's acceleration?

Explanation:

You can use the formula a = (v2 - v1)/t, where a is the acceleration, v1 is the initial velocity, v2 is the final velocity, and t is the time interval.

In this case, v1 is 0 m/s (since the car starts at rest) and v2 is the final velocity of the car after it travels 100 m in 5 seconds. You can use the formula v = d/t to find the final velocity, where v is the velocity, d is the distance traveled, and t is the time taken. Plugging in the given values, you get:

v = d/t

= 100 m / 5 s

= 20 m/s

Now you can plug in the values for a, v1, v2, and t into the formula to find the acceleration:

a wall of death rider is driving a mehran - a popular hatchback. the radius of the wall of death (or maut ka kuwa in the vernacular) is 5m. the top speed that his old mehran can get to is 80 km/h. what is the minimum coefficient of friction between rubber and wood that would keep our friend and his mehran from crashing down?

Answers

The minimum coefficient of friction needed to keep the car from crashing down is 16.3. That's mean the friction force between the tires and the surface of the wall of death must be at least 16.3 times greater than the normal force acting on the car.

The minimum coefficient of friction needed to keep the car from crashing down is determined by the forces acting on the car. When a car is driving in a circle, it is constantly being pulled outward by a force called centrifugal force. This force is equal to the mass of the car multiplied by the square of its speed, divided by the radius of the circle it is driving in. In order to keep the car from crashing, the friction force between the tires and the surface of the wall of death must be greater than or equal to the centrifugal force.

The formula for the minimum coefficient of friction needed is:

μ = Fcentrifugal / Fnormal

where μ is the coefficient of friction, Fcentrifugal is the centrifugal force acting on the car, and Fnormal is the normal force acting on the car.

To calculate the minimum coefficient of friction needed, you need to first calculate the centrifugal force acting on the car. The formula for this is:

Fcentrifugal = [tex]mv^2 / r[/tex]

where m is the mass of the car, v is the speed of the car, and r is the radius of the circle.

Plugging in the values from your question, the centrifugal force is:

Fcentrifugal = [tex](800 kg) * (80 km/h)^2 / (5 m)[/tex]

= 128,000 N

The normal force is equal to the weight of the car, which is the mass of the car multiplied by the acceleration due to gravity. The weight of the car is:

Fnormal = (800 kg) * (9.8 m/s²)

= 7,840 N

Plugging these values into the formula for the minimum coefficient of friction, we get:

μ = 128,000 N / 7,840 N

= 16.3

Thus, the minimum coefficient of friction is 16.3.

The force on the vehicle is 500000 N means that a force of 500000 N is being applied to the vehicle and its momentum is changing at a rate of 500k kg m/s²

Well, we all know Force is equal to the product of mass and acceleration. Force is nothing but, a measure of the rate of change of momentum of an object. When we say the force acting on any particle is x newtons, we mean that the particle is accelerating at x/m meter per square second at that instant  (where m is the mass of the particle). In this case, we have been given that the force applied on the vehicle is 500000 newtons. 500000 newtons can be also written as 500k Newtons. So when we are applying a force of 500k Newtons on the vehicle, in this case, we can't really find the acceleration of the vehicle as no mass is given. But we can tell one thing here, that is, a force of 500k Newtons on the vehicle means that at that particular instant the rate of change of momentum is

500k kg m/s².

Sound wave is a mechanical wave moves through a medium only. The frequency of a sound wave is called its pitch and it is the number of wave cycles obtained per unit time.

The wavelength for the fundamental frequency is = 2L

= 2 × 0.32 = 0.64 m

Now the speed of the sound waves in air = 340 m/s

frequency = 440 Hz or s⁻¹.

Thus, the  wavelength of sound wave = speed/ frequency

= ( 340 m/s)/  440 Hz = 0.77 m.

This change in wavelength from that of the  fundamental vibration is due to the change in speed of sound waves in different mediums.

if the coefficient of kinetic friction between a 26 kg crate and the floor is 0.34, what horizontal force is required to move the crate at a steady speed across the floor?

Answers

If the coefficient of kinetic friction between a 26 kg crate and the floor is 0.34, the required horizontal force to move the crate at a steady speed is 86.6 Newton.

Steady speed means the acceleration is zero.

According to the Newton's first law of motion, to produce a motion with zero acceleration, the net force must be equal to zero.

In the problem, the forces are the horizontal force and the friction force.

Hence, the net force is:

∑F = 0

Fh - friction = 0

Fh - μ . mg = 0

Where:

Fh = horizaontal force

m = mass of the crate = 26 kg

g = acceleration due to gravity = 9.8 m/s²

μ = coefficient of kinetic friction = 0.34

Plug all the parameters into the equation,

Fh - 0.34 x 26 x 9.8 = 0

Fh = 86.6 N

Answers

The total electric potential due to these charges at the  center is 9 * 10^5 J/C.

How do you calculate potential due to charge?By multiplying K, the electric constant, by one charge, then by the other charge, and finally by the distance between the two charges, we may determine the electrical potential energy between two charges.A point charge's electric potential is V=kQ/r, or V = k Q / r. Electric field is a vector while electric potential is a scalar. The voltage resulting from a combination of point charges can be calculated by adding voltages as integers, whereas the overall electric field can be calculated by adding individual fields as vectors.

V = k × [q/r]

V = electric potential energy.

q = point charge.

r = distance between any point around the charge to the point charge.

k = Coulomb constant; k = 9.0 × 10^9 N.

at  The center (0,0)

r = 4 cm

due to Q1

v1= k ( 2.00 μC/ 4 * 10^-2) = 9.0 × 10^9 * 0.5* 10^-4 =4.5 * 10^5 J/C

due to Q2

v2 = k ( 2.00 μC/ 2 cm) = 9.0 × 10^9 * 1* 10^-4 =4.5 * 10^5 J/C

total potential at (0.0) = 9 * 10^5 J/C

If a net force of 10. Newtons acts on a 6. 0-kilogram mass for 8. 0 seconds, the total change of momentum of the mass is.

Answers

The total change of momentum of the mass is 80.016 kgm/s approximately 80 kgm/s.

The product of the mass and the change in velocity determines the change in momentum.

Since the mass is a constant, it stays the same.

A shift in momentum is caused by a change in velocity.

The letter " Δp" stands for the change in momentum.

As per the question, Net force = 10 N

Mass of the object = 6.0 Kg.

Time = 8.0 Sec.

As per Newton's first law of motion:

v=u+at, where, v = final velocity

u = initial velocity

a = acceleration

t = time

So, we can write it as:  vf - vi = at (vf= final velocity, vi=initial velocity)---(i)

Applying Newton's second law

F = ma.

So, 10 = 8*a => a = 1.667 m/s^2.

So, from (i),

vf - vi = 1.667 x 8 = 13.336 m/s ---(ii)

So, change in momentum M = m(vf - vi)

Where M is a change in momentum, m is mass

So, the value of change in momentum will be

M = 6 x 13.336 = 80.016 kgm/s approximately 80 kgm/s.
