The correct answer is Neutron
Explanation:
As shown in the diagram the sub-particles in atoms are electrons, neutrons, and protons. From these, the two types of particles that are in the nucleus or center of the atom are neutrons and protons. Moreover, neutrons differ from protons because these are neutral or are not charged. According to this, the uncharged particles in atoms are neutrons.
Moreover, the number of neutrons can be calculated by subtracting the atomic number (number of protons) to the mass number (number of atoms and protons). For example, if in an atom the mass number is 12 (protons and neutrons)and the atomic number is 6 (number of protons), the neutrons are 6 (12 - 6 = 6). According to this, the correct answer is the neutron.
Answer:
0.027 cubic ft/min
Explanation:
Volume of water is V=V(t) Depth of water is h=h(t)
The relationship between V and h is
V=π/3.r2.h
Let
h0= the height of the cylinder = 24ft, r0= the radius of the opening = 10ft.
Since water level (h) rise with respect to flow rate we find an expression for r and substitute into V
r/h = r0/h0= 10/24 = 5/12
r = (5/12) h,
Substitute for r in V
so,
V=1/3.π.(h2)square = 1/3.π. 25/144.(h3)
When
h= 16ft
and dV/dt = 20ft3/min
,
dV/dt =1/3*π*25/144*h3*(dh/dt)
20ft3/min= 1/3*π* 25/144*h3*(dh/dt)
20 = 1/3*π*(16)3.(dh/dt)
Make dh/DT subject of formula
dh/dt=(20*3*144)/(25*π*4096) = 8640/321740.8
=
dh/dt= 0.027 ft3/min
I took this question before, and it is A) size in area.
