Which statement correctly compares nuclear fission with nuclear fusion?
A. Nuclear fission forms a larger nucleus, and nuclear fusion forms
smaller nuclei.
B. Nuclear fission uses a common isotope, and nuclear fusion uses a
rare isotope.
C. Nuclear fission reactions demonstrate the conservation of atomic
number, and nuclear fusion reactions do not.
D. Both nuclear fission and nuclear fusion produce energy from
matter
Help please
Answer:
Both nuclear fission and nuclear fusion produce energy from
matter
:D
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
What is nuclear fusion?The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.
The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.
As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.
For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
Hence option D is correct.

What will be the mass of a body at the center of the earth as compared to other places on
the earth?
Answer:
The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.
Explanation:
It's because the mass of the object doesn't change by moving it to next place.

A double slit produces a diffraction pattern that is a combination of single and double slit interference. Find the ratio of the width of the slits to the separation between them, if the first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern. (This will greatly reduce the intensity of the fifth maximum.)
Answer:
The ratio of the width of the slits to the separation between them is 1:5
Explanation:
For this set of question
n = 1, m = 5
As we know for nth minimum
[tex]D sin\theta =n \lambda[/tex]
For mth Maximum
[tex]d sin\theta =m \lambda[/tex]
From the above two equations we get
[tex]Sin\theta = \frac{1*\lambda}{D} \\d * \frac{1*\lambda}{D} = 5 *\lambda\\\frac{D}{d} = \frac{1}{5}[/tex]
The ratio of the width of the slits to the separation between them is 1:5

Answer:
C. Alkynes
Explanation:
please answer this time question in do not send a link to an unknown website or you are getting reported.
(1) Use Newton's second law: The force F required to accelerate a mass m with acceleration a satisfies
F = m a
So the force needed to accelerate the lion-stretcher system is
F = (175 kg) (2 m/s²) = 350 N
(2) Average speed is defined as the ratio of distance traveled to the time it takes to travel that distance, so in this case the bus's average speed is
(280 km) / (4 h) = 70 km/h
(3) The vertical lines in the plot split up the distance function into 5-minute chunks. The one with the highest average speed is the one over which the distance changes the most. Roughly, the average speeds over each of the given choices is
• 0 to 5 min : (1500 m - 0 m) / (5 min) = 300 m/min
• 10 to 15 min : (3250 m - 2500 m) / (5 min) = 150 m/min
• 15 to 20 min : (3750 m - 3250 m) / (5 min) = 100 m/min
• 25 to 30 min : (4500 m - 4250 m) / (5 min) = 50 m/min
(4) Velocity is a vector, so it has both magnitude and direction. A car moving at constant velocity would be traveling at the same magnitude and direction. But a car on the circular track is constantly turning and changing direction.
An archer shoots an arrow 75 m distant target; the bull's-eye of the target is at the same height as the release height of the arrow. If d = 75 m and v = 37 m/s. At what angle must the arrow be released to hit the bull's-eye if its initial speed is 37 m/s?
Answer:
[tex]16.25^{\circ}[/tex]
Explanation:
R = Horizontal range of projectile = 75 m
v = Velocity of projectile = 37 m/s
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
Horizontal range is given by
[tex]R=\dfrac{v^2\sin2\theta}{g}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{Rg}{v^2}}{2}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{75\times 9.81}{37^2}}{2}\\\Rightarrow \theta=16.25^{\circ}[/tex]
The angle at which the arrow is to be released is [tex]16.25^{\circ}[/tex].

do electronics harm our mental physical and social health
Answer:
(I will talk in my opinion only)
electronics do harm our mental health but they are also helpful ones like mobile both a boon and a curse
physical health is greatly affected and it's something no need to explain
social ( for me ) my only place to be social and talk people is brainly so for me mobile is very important
Answer:
Just a little bit. You should not be on electronics all the time. I know some people that are so addicted to there electronics that they won't even hang out with people. If you are at the point where you think about things other than school, friends, and family...you should think about getting off of your electronics and go play with a neighborhood friend outside, or have a sleepover! Your whole life should not count on your phone, iPad, or your laptop.

100 cm cubic of water is mixed with 50 centimetres cubic of concentrated acid of density 1.2 gram per centimetre cube assuming no change in volume find the average density of the mixture the density of water is 1.0 gram per centimetre cube
Answer:
Average Density = 1.07 g/cm³
Explanation:
The average density of the whole mixture is given by the following formula:
[tex]Average\ Density = \frac{mass\ of\ whole\ mixture}{volume\ of\ whole\ mixture}[/tex]
where,
volume of whole mixture = volume of water + volume of acid
volume of whole mixture = 100 cm³ + 50 cm³ = 150cm³
mass of whole mixture = mass of water + mass of acid
mass of whole mixture = (volume of water)(density of water) + (volume of acid)(density of acid)
mass of whole mixture = (100 cm³)(1 g/cm³) + (50 cm³)(1.2 g/cm³)
mass of whole mixture = 160 g
Therefore,
[tex]Average\ Density = \frac{160\ g}{150\ cm^3}[/tex]
Average Density = 1.07 g/cm³
