Do u think the benefits of nuclear energy outweigh the dangers
Answer:
While there is no such thing as 100 percent safe, having nuclear energy is much safer than you think. It's thousands of times safer than conventional coal and other fossil-fuel-derived energy, not to mention the specter of environmental disaster from continued use of carbon-based energy sources.29 may. 2011

When using the lens equation, a negative value as the solution for d baseline i indicates that the image is
A. real
B. virtual
C. upright
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.

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
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.

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 boat at anchor is rocked by waves whose crests are 28 m apart and whose speed is 7 m/s. How often do these waves reach the boat? State your answer in terms of frequency (Hz) and period T (seconds).
Answer:
0.25 Hz
4 s
Explanation:
Speed = wavelength × frequency
7 m/s = 28 m × f
f = 0.25 Hz
Frequency = 1 / period
0.25 Hz = 1 / T
T = 4 s

Growing up a tree is a conversion from light energy to chemical energy.
What is law of energy conservation?Energy can neither be created nor be destroyed , it gets only transferred from one form to another.
What is photosynthesis?The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.In simple words by the process of photosynthesis a tree makes food for itself.What happens when a tree grows?Tree makes food by absorbing the sunlight.The energy of the sunlight is used in making of ATPs in trees.ATP ( Adenosine triphosphate ) is used in various operations in trees.So, the sunlight is light energy which get converted into ATPs , which is chemical energy.
Thus, Growing up a tree is a conversion from light energy to chemical energy.

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe
Answer:
20 gram of H as the greastest volume
Explanation:
Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe
Given that,
40.0 g of Ar
20.0 g of Ne
20.0 g of h
24.0 g of he
The ideal gas equation ; Pv = nRT
where P is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of mole
which is equal to
n = m / M
where m is the given mass
M is the molar mass
The given gas sample are at the same temperature and pressure,
So, the temperature, pressure and gas constant are fixed.
Therefore the volume is proportional to the given mass and molar mass
V ∝ m/M
Substitute the given mass and molar mass of given masses for comparison
No of mole of Ar = mass / molar mass
= 40 / 40 = 1 mole
No of mole of Ne = mass / molar mass
= 20 / 20 = 1 mole
No of mole of h = mass / molar mass
= 20 / 1 = 20 mole
No of mole of he = mass / molar mass
= 24 / 4 = 6 mole
Hence, 20 gram of H as the greastest volume

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
