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!!
If this were to happen then the particle would be at the node (the point in the middle where the lines meet). Therefore, the particle will not move up or down because you can see the waves interfere destructively so there is no movement at the node.
answer. The particle will remain stationary due to interference.
Simply because the baseball is much lighter than the bowling ball. Making it easier for the average adult to throw the baseball farther than the bowling ball
Answer : The correct option is, (D) 278 K
Explanation :
We are given temperature 
.
Now the conversion factor used for the temperature is,
where, K is kelvin and 
is Celsius.
Now put the value of temperature, we get
Therefore, the temperature 278 K is equal to the
Answer:
B. Longer than t s,
Explanation:
Gravitational accln on earth is 9.8 m/s^2,
and one you provided as on moon is 1.6 m/s^2
that mean on moon gr. accl. is lesser!
now the time taken on earth will be lesser cuz from the same height if you drop the object from rest!
since accln on earth is higher,the object will attain higher velocity as compare to that of on moon!
