D. inverted
When using the lens equation, a negative value as the solution for d baseline i indicates that the image is Virtual. The correct option is B.
What is reflection?When a light strikes on a shiny surface, it reflects back the light ray in the same medium. The phenomenon is called reflection and the ray is called the reflected ray.
From the Len's maker formula, e have
1/f = 1/u + 1/v
where f = radius of curvature /2
So, the negative value as the solution for d baseline i indicates that the image is Virtual.
Thus, the correct option is B.

Indicate what a specific property of matter is. Also explain why the specific properties of matter are useful compared to the general ones.
Solution
The specific properties of matter are properties that describes the intensive properties of the system. They are properties that do not depend on or change with the extent or size of the system. They are usually obtained by dividing the generalised properties or extensive properties by the extent or size of matter to make them independent of size/extent/Mass.
Examples of specific properties include specific heat capacity, specific volume etc. They usually have units of general units/Mass units.
The specific properties of matter are more important than the general ones because
- They help in general comparisons of the properties of different materials. They are used to rank, classify and compare properties of different materials.
- They are used in reference table/data to easily record easily accessible properties of matter. It helps to record standards that are general and independent of sizes/extents/Mass, thereby keeping the reference table/data/chart precise and concise.
- They provide us with values that are easy to memorize and remember, unlike trying to cram the different properties of different masses/sizes of matter.
In Spanish/En español
Las propiedades específicas de la materia son propiedades que describen las propiedades intensivas del sistema. Son propiedades que no dependen ni cambian con la extensión o el tamaño del sistema. Por lo general, se obtienen dividiendo las propiedades generalizadas o las propiedades extensivas por la extensión o el tamaño de la materia para hacerlas independientes del tamaño / extensión / masa.
Los ejemplos de propiedades específicas incluyen capacidad calorífica específica, volumen específico, etc. Usualmente tienen unidades de unidades generales / unidades de masa.
Las propiedades específicas de la materia son más importantes que las generales porque
- Ayudan en las comparaciones generales de las propiedades de diferentes materiales. Se utilizan para clasificar, clasificar y comparar propiedades de diferentes materiales.
- Se utilizan en la tabla / datos de referencia para registrar fácilmente propiedades de materia fácilmente accesibles. Ayuda a registrar estándares que son generales e independientes de tamaños / extensiones / masa, manteniendo así la tabla / datos / tabla de referencia precisa y concisa.
- Nos proporcionan valores que son fáciles de memorizar y recordar, a diferencia de tratar de agrupar las diferentes propiedades de diferentes masas / tamaños de materia.

Chris has a part time job as a cannon ball catcher for the circus. One day he was located an unknown distance away from the cannon. A cannonball was fired from the cannon at 425 m/s. The speed of sound was 345 m/s. Unfortunately the cannonball went past Chris 0.20 s before he heard the sound of the blast. How far away was the cannon from Chris?
show work with answer for brainliest plz
Answer: 366.56 meters.
Explanation:
Velocity of the cannon ball = 425m/s
Velocity of sound = 345 m/s
For the "position" of both, we have the equation:
Pc = 425m/s*t
Ps = 345m/s*t
Where t is time in seconds.
If the position of Chris is X, we have that if the ball reaches the position of Chris in T seconds, then the soundwave reaches the position of Chris in T + 0.20 seconds, we can write this as:
425m/s*T = X
345m/s*(T + 0.20s) = X
Now we can solve this system of equations. First we can replace the first equation in the second equation and get
345m/s*(T - 0.20s) = 425m/s*T
Now we solve this for T.
345*T + 69 = 425*T
69 = (425 - 345)*T = 80*T
T = 69/80 = 0.8625 seconds.
Now we replace this in the first equation and get:
X = 425m/s*T = 425m/s*0.8625s = 366.56 meters.

Rohit placed a pencil perpendicular to principal axis in front of a converging
mirror of focal length 30 cm. The image formed is twice the size of the pencil.
Calculate the distance of the object from the mirror.
Answer:
45 cm ( in my opinion)♀️
Explanation:
( Using the mirror formula)
1/ u + 1/v = 1/f
( introducing magnification; m into the formula )
u( 1/u + 1/v ) =u×1/f
1 + u/v =u/f
( But u/v =1 ÷v/u= 1/m)
1 +1/m =u/f
(Supposing m is actually equal to 2, and f =30 cm, then;)1 + 1/2 =u/30
2+1= u/15
3=u/15
3×15=u
45 cm=u

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?
Answer:
white
Explanation:
This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.
Now, in diffraction fo a single slit we always have a central maximum (for all the colors)
This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white
A sphere of radius 10.0cm is moulded into a uniform cylindrical wire of same radius r calculate length in millimeters
Answer:
133.33 mm
Explanation:
First we need to find the volume of the sphere. The volume of a sphere is given by:
V = (4/3) * pi * r^3
With a radius of 10 cm, we have:
V = (4/3) * pi * r^3 = 4188.79 cm3
The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:
V = pi * r^2 * h
Where h is the height of the cylinder, and for this case, it will be the length.
The radius is the same old radius, so we have:
4188.79 = pi * 10^2 * h
h = 4188.79 / 100pi = 13.3333 cm
In millimeters, we have h = 133.33 mm

You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the
resistance?
A 12 ohms
B 0.75 ohms
C 3.0 ohms
D.0.5 ohms
E. 6.0 ohms
Answer:
The answer is "C. 3.0 ohms".
Explanation:
Ohm's law states the following:,
V = IR
where:
Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts
Current (I) = 2.0 amps
Resistance (R) = ? ohms
To solve for Resistance (R) the equation must be rearranged this way:
R = V / I
Then, the variables must be replaced with the known values:
R = 6.0 volts / 2.0 amp
R = 3.0 ohms
The answer is C. 3.0 ohms.

Object A has a mass of 10 kg and is moving at a velocity of 2.0
m/s. So Object A's momentum is - kg. m/s.
Answer:20kgm/s
Explanation:
Mass=10kg
Velocity=2m/s
Momentum=mass x velocity
Momentum=10 x 2
Momentum=20
Momentum=20kgm/s
The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.
What is momentum?Momentum is the product of mass and velocity of a moving object.
If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be
p = 10 × 2.0
p = 20 kg.m/s
Thus, the momentum of the object A is 20 kg.m/s

El coeficiente de variación de la resistencia con la temperatura del carbón es -0.0005/°c.Si la resistencia de una resistencia de carbón es de 1000 a0°c , determine su resistencia a 120°c
Answer:
R (120) = 940Ω
Explanation:
The variation in resistance with temperature is linear in metals
ΔR (T) = R₀ α ΔT
where α is the coefficient of variation of resistance with temperature, in this case α = -0,0005 / ºC
let's calculate
ΔR = 1000 (-0,0005) (120-0)
ΔR = -60 Ω
ΔR = R (120) + R (0) = -60
R (120) = -60 + R (0)
R (120) = -60 + 1000
R (120) = 940Ω
Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas
v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E
The first and second velocities of the car, with four washers attached to the pulley, are both 0.125 m/s.
We must apply the following calculations to determine the car's first and second velocities with the four washers attached to the pulley:
v1 = 0.25 m / t1
v2 = 0.25 m / (t2 - t1)
Here, t1 denotes the typical time needed for the car to go 0.25 metres, and t2 is the typical time needed to travel 0.50 metres.Let's say that t1 and t2 are the typical times, each lasting two seconds on average.The first formula allows us to determine v1:
v1 = 0.25 m / 2 s = 0.125 m/s
Using the second formula, we can calculate v2:
v2 = 0.25 m / (4 s - 2 s) = 0.125 m/s
Table E can be used to record these values as the velocities at the relevant distances.
