Answer:
See explanation
Explanation:
The use of Uranium - 234 to generate electricity depends on a fission reaction. The uranium nuclide is bombarded by fast moving neutrons leading to a chain reaction. Control rods and moderators are used to keep the nuclear reaction under control.
As the nuclear reaction proceeds, heat is generated and steam is consequently produced. This steam is used to turn a turbine and electricity is thereby generated.
Answer: A convex lens is used to converge ligtht.
Explanation:
A concave lens is a lens that is thicker on the ends than in the middle. As consequence of this, a concave lens diverges (separate) the rays of light. A concave lens is also called diverging lens.
A convex lens is is thicker in the middle than on the ends. As consequence of this, a convex lense converge the parallel rays that pass through it. A convex lens is also called converging lens.
Answer:
98 g/mol
Explanation:
atomic mass for hydrogen=1
atomic mass for sulphur=32
atomic mass for oxygen=16
atomic mass for sulphuric acid=2H + S + 4O
=2x1 + 32 + 4x16
2+32+64=34+64
=98g/mol
Answer: these are the values of density that complete the table
Sample density
A 1024
B 1027
C 1026
D 1025
E 1028
Procedure: take the values of temperature and salinity for each sample given in the table, and enter the graph to read the corresponding density value.
1) Sample A: temp = 21°C, salinity = 34%
Locate the value 34 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 21 for the vertical axis, read the value of the density on the curve that passes through the point (34, 21). That value is
density = 1024 g/cm^3.
That is the value to copy on the table.
2) Sample B: temp = 11°C, salinity =35 %
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 11 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 11). That value is
density = 1027 g/cm^3.
That is the value to copy on the table.
3) Sample C: temp = 12°C, salinity = 34%
Locate the value 34 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 12 for the vertical axis,
read the value of the density on the curve that passes through the point
(34, 12). That value is
density = 1026 g/cm^3.
That is the value to copy on the table.
4) Sample D: temp = 19°C, salinity = 35%
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 19 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 19). That value is
density = 1025 g/cm^3.
That is the value to copy on the table.
5) Sample E: temp = 3°C, salinity = 35%
Locate the value 35 on the horizontal axis (salinity axis), move
vertically upward until reaching the level of 3 for the vertical axis,
read the value of the density on the curve that passes through the point
(35, 3). That value is
density = 1028 g/cm^3.
That is the value to copy on the table.
