Question: It takes four hydrogen nuclei to create one helium nucleus in the proton-proton chain, which is the main energy source of the Sun. If a single hydrogen nucleus has a mass of 1.6726 x 10-27 kg and single helium nucleus has a mass of 6.6447 x 10-27 kg,
Part A: How much mass is converted into energy to create four helium nuclei?
Part B: How much energy is generated in creating four helium nuclei?
This is a physic question, reply as soon as possible. Thanks.
4. A ball is kicked toward a fence from a point 32 meters away. The velocity of the ball as it leaves the kicker's foot is 24 m/s at an angle of 37 degrees above the horizontal. The top of the fence is 2.0 meters high. Assuming air resistan..

A particle moves with constant velocity [4, -2, 1] m/s. If its mass is 3 kg, what is its kinetic energy? One of the forces acting on it is given by F = [-1, 2, 2] N. Find the work done by this force on the particle as it moves a distance of 3 m.
A 0.460 kg wood block is firmly attached to a very light horizontal spring (k = 160 N/m) as shown in Fig. 6-40. It is noted that the block-spring system, when compressed 5.0 cm and released, stretches out 2.3 cm beyond the equilibrium position before..
