Chapter 10, Problem 1RQ
Why does helium fusion require a higher temperature than hydrogen fusion?
Expert Solution & Answer
To determine
Why helium fusion requires a higher temperature than hydrogen fusion.
Answer to Problem 1RQ
The energy required for helium fusion is much higher than what is required for hydrogen fusion.
Explanation of Solution
Hydrogen has one proton in its nucleus whereas helium has two.
Protons are positively charged particles.
During fusion, two nuclei (or more) combine together to form a heavier nucleus.
Therefore, positive charges are brought together during fusion and bound into a single nucleus.
But, like charges repel. To hold them together, a large amount of energy is required.
Fusion of two hydrogen atoms involves binding two protons while helium fusion involves bringing together four protons.
Since the number of protons to be bound in helium fusion is more than that in hydrogen fusion, much more energy is required for this reaction to take place.
Therefore, helium fusion requires a higher temperature than hydrogen fusion.

You have just bought a new bicycle. On your first riding trip, it seems that the bike comes to rest relatively quickly after you stop pedaling and let the bicycle coast on flat ground. You call the bicycle shop from which you purchased the vehicle and describe the problem. The technician says
that they will replace the bearings in the wheels or do whatever else is necessary if you can prove that the frictional torque in the axle of the wheels is worse than -0.02 N . m. At first, you are discouraged by the technical sound of what you have been told and by the absence of any tool to
measure torque in your garage. But then you remember that you are taking a physics class! You take your bike into the garage, turn it upside down and start spinning the wheel while you think about how to determine the frictional torque. The driveway outside the garage had a small
puddle, so you notice that droplets of water are flying off the edge of one point on the tire tangentially, including drops that…

- John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of 0 = 17.5° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 403 N is exerted at the center of the wheel, which has a radius of 16.0 cm. Assume the brick remains fixed and does not slide along the ground. Also assume the force applied by John is directed exactly toward the center of the wheel.
