Answer:
the answer is D metal resting
Explanation:
I just think that because if you treasure can that's physical charge by dropping where you create a physical charge melting and Ice Cube might be 1 but I feel like metal resting is more likely
Answer:
D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us
Explanation:
By Einstein's theory of relativity the maximum value of the red shift is 1. This correspond to a case in which the observed frequency equals the emitted frequency:
in other cases the red shift is lower than one.
Hence, the gravitational lens change the measurements of the observed frequency and because of that we calculate a greater red shift.
Hence, the answer is:
D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us
hope this helps!!
Answer:
Cp = 0.142 [cal/g*°C].
Explanation:
In order to solve this problem, we must use the following equation of thermal energy.
where:
Q = heat energy = 60 [cal]
Cp = specific heat [cal/g*°C]
T_final = final temperature = 10[°C]
T_initial = initial temperature =40[°C]
m = mass of the substance = 14 [g]
Now replacing:
Answer:If you add a proton to the atom, it becomes beryllium (atomic number = 4).
It is an ion with a +1 charge, since the number of protons (4) no longer equals
the number of electrons (3).
So you have a beryllium +1 ion - the best answer choice is C.
Explanation:if this isn’t right I am so sorry
