Answer: The acceleration that is directed radially towards the center of the circle having a magnitude equal to the square of the speed of the body along the curve is divided by the total distance from the center of the circle to the moving body.

Answer:
a). V = 3.13*10⁶ m/s
b). T = 1.19*10^-7s
c). K.E = 2.04*10⁵
d). V = 1.02*10⁵V
Explanation:
q = +2e
M = 4.0u
r = 5.94cm = 0.0594m
B = 1.10T
1u = 1.67 * 10^-27kg
M = 4.0 * 1.67*10^-27 = 6.68*10^-27kg
a). Centripetal force = magnetic force
Mv / r = qB
V = qBr / m
V = [(2 * 1.60*10^-19) * 1.10 * 0.0594] / 6.68*10^-27
V = 2.09088 * 10^-20 / 6.68 * 10^-27
V = 3.13*10⁶ m/s
b). Period of revolution.
T = 2Πr / v
T = (2*π*0.0594) / 3.13*10⁶
T = 1.19*10⁻⁷s
c). kinetic energy = ½mv²
K.E = ½ * 6.68*10^-27 * (3.13*10⁶)²
K.E = 3.27*10^-14J
1ev = 1.60*10^-19J
xeV = 3.27*10^-14J
X = 2.04*10⁵eV
K.E = 2.04*10⁵eV
d). K.E = qV
V = K / q
V = 2.04*10⁵ / (2eV).....2e-
V = 1.02*10⁵V
Groups
Same number of valence electrons
Li, Na, K
Explanation:
A.
If the periodic table is not color coded, the groups of elements gives the arrangement of atoms with the same chemical properties.
All elements that are in the same group have the same chemical properties.
Periodic table groups are also called family. They are the vertical columns on the periodic table.
B.
Elements that same number of electrons in outermost shell have the same chemical properties.
The outermost shell is called the valence shell of an atom.
They are the shell containing the most loosely held electrons. Group 1 has just one electron in their outermost shell.
C.
Li Na k group 1
F Cl Br group 7

Answer:To ensure significant dialogue which will guarantee that the needed Products meets specifications
It will help to develop a better Operational model for the users.
Explanation: The design phase is one of the most critical phase in product development,it is in this phase that the product structure, contents and specifications are put into action. It is necessary that the end users have a significant time to dialogue with the project or product development team to guarantee that the end product meets specifications.
It is also necessary to spent adequate time in order to make the product user friendly (easy to operate and maintain).
