E=mc^2 n its given 1kg = 9x10^16J
so need to figure out the total mass loss n u can find the energy released
mass loss when 4x H atom combines to form 1x He atom in a fusion reaction is given as 4.59x10^-29kg
1 mole of He has 6.02x10^23 He atoms
so 2.7 moles of He has 2.7x6.02x10^23 He atoms
the total mass loss for 2.7 moles of He created in a fusion reaction
= 2.7x6.02x10^23 x 4.59x10^-29kg
= 7.46x10^-5kg
radiation energy released from this fusion reaction
= 7.46x10^-5 x 9x10^16J
= 6.7x10^12J
its 60 BILLION times more than burning carbon!!
The first one,second one and the forth one are correct
Complete Question
The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, which orbits a rather average star in the distant Garbanzo Galaxy. A scouting party sets out to explore. The party's leader–a physicist, naturally–immediately makes a determination of the acceleration due to gravity on the Pink Planet's surface by means of a simple pendulum of length 1.08m. She sets the pendulum swinging, and her collaborators carefully count 101 complete cycles of oscillation during 2.00×102 s. What is the result? acceleration due to gravity:acceleration due to gravity: m/s2
Answer:
The acceleration due to gravity is
Explanation:
From the question we are told that
The length of the simple pendulum is 
The number of cycles is 
The time take is
Generally the period of this oscillation is mathematically evaluated as

substituting values


The period of this oscillation is mathematically represented as

making g the subject of the formula we have
![g = \frac{L}{[\frac{T}{2 \pi } ]^2 }](https://tex.z-dn.net/?f=g%20%3D%20%5Cfrac%7BL%7D%7B%5B%5Cfrac%7BT%7D%7B2%20%5Cpi%20%7D%20%5D%5E2%20%7D)

Substituting values

An 'alpha particle' is the same thing as the nucleus of a helium atom ...
a little bundle made of 2 protons and 2 neutrons.
A 'beta' particle is an electron.
The mass of an alpha particle is more than 7,000 times the mass of
an electron, so it certainly takes more energy to get it moving.
I think its b because when there is unbalanced forces it accelerates.
Hope this helps you out
