Answer:
I believe the answer is D.
Explanation:
Protons are found inside the nucleus so are neutrons. Electrons are found outside the nucleus.
500 N is the answer, you just tell that the moon is attracted towards the person because of the Earth's huge mass.
Answer:
Explanation:
parallel capacitances add directly
Series capacitances add by reciprocal of sum of reciprocals.
Ceq = [ C ] + [1 / (1/C + 1/C)] + [1 / (1/C + 1/C + 1/C)]
Ceq = [ C ] + [C / 2] + [C / 3]
Ceq = [ 6C/6 ] + [3C / 6] + [2C / 6]
Ceq = 11C/6
Answer:
Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/
(newtons per meter squared).
Wave 3 will move the slowest, the statement could made about the data collected in Hamish's table
Answer: Option C
<u>Explanation:
</u>
Sound waves require medium to pass from one to another. Depending upon the density of molecules in the medium, the speed of the sound waves can be determined. As we know that compression and rarefactions will be formed for propagation of sound waves when the waves collide with molecules of the medium.
So, if there is less molecules present in the medium or loosely packed molecules present in the medium with high mean free path length than the sound wave will be travelling slowly in that medium.
Thus, as we known that gas has the loosely packed molecules among the other states of matter, so wave 3 which is made to pass through the gas medium will be propagation at the lowest speed or will move the slowest compared to other 3 gases made to propagate in solid and liquid mediums.
