Answer:
with the mirror into the right direction
Explanation:
a. 2Na+ Cl2=2NaCl is the most possible chemical reaction that can occur
The velocity of Satellite A is 2% greater than velocity of satellite B.
The given parameters;
- <em>Altitude of Satellite A = 500 km</em>
- <em>Altitude of Satellite B = 800 km</em>
The forces acting on the Satellites are given as follows;
Thus, the velocity of Satellite A is 2% greater than velocity of satellite B.

The answer would be energy, because all wave emitters give off at least one type of energy....
Answer: v = 3.57×10^6 m/s; R = 4.42×10^-3m; T = 7.78×10^-9 s
Explanation:
Magnetic force(B) = 4.60×10^-3 T
Electric force(E) = 1.64×10^4 V/m
Both forces having equal magnitude ;
Magnetic force = electric force
qvB = qE
vB = E
v = (1.64×10^4) ÷ (4.60×10^-3)
v = 3.57×10^6 m/s
2.) Assume no electric field
qvB = ma
Where a = v^2 ÷ r
R = radius
a = acceleration
v = velocity
qvB = m(v^2 ÷ R)
R = (m×v) ÷ (|q|×B)
q=1.6×10^-19C
m = 9.11×10^-31kg
R = (9.11×10^-31 * 3.57×10^6) ÷ (1.6×10^-19 * 4.6×10^-3)
R = 32.5227×10^-25 ÷ 7.36×10^-22
R = 4.42×10^-3m
3.) period(T)
T = (2*pi*R) ÷ v
T = (2* 4.42×10^-3 * 3.142) ÷ (3.57×10^6)
T = (27.775×10^-3) ÷(3.57×10^6)
T = 7.78×10^-9 s
