Answer:
B, to predict star count
Explanation:
the rest can be done with rulers, Einstein cans and public surveys, we can't predict how many stars there will be, but we can take pictures of them instead
C kinetic energy bc it consists of the total kinetic energy of all its atoms and molecules. It is a form of energy related to heat and temperature
Answer:
More than two million electron volts.
Explanation:
More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
Answer:
Potential difference will be 151.9 volt
Explanation:
We have given capacitance of the capacitor 
Voltage V = 49 Volt
Dielectric constant K = 3.1
We have to find the potential difference
We know that when a dielectric medium is introduced then p[otential difference is increases by k times
As the dielectric constant k = 3.1
So potential difference will be = 3.1×49 = 151.9 volt
The correct answer are
a) "The number of muscle fibers best determines how powerful a muscle will be"
b) "The more a muscle shortens, the more power it generates."
Reason :
Muscle fiber in longitudinal directions generate more power
Multipennate muscles do not produce much power because the tendon branches within muscle
