Asolar model is used to calculate the expected temperature and density at all depths within the sun. these results are then used to calculate the expected fusion rate within the sun. we have confidence that the model is correct because it agrees with the observed characteristics of the sun. which of the following observations can be used to check that we really do know the sun’s internal fusion rate?
select all that apply.
a. measurements of the varying number of sunspots on the sun over time
b. measurements of the sun’s total energy output into space
c. observations of neutrinos coming from the sun
d. observations of the total x-ray emission from the sun’s corona
e. measurement of the sun’s mass

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.

To understand the concept of isomers and be able to answer questions relating to molecular formulas, structures, and condensed structures of isomers. molecules that have the same molecular formulas but different structures are called isomers. for example, hexane and 2-methylpentane have same the molecular formula, c6h14.
