Answer:
Explanation:
Given,
Width of slit, W = 5.7 x 10⁻⁴ m
Distance between central bright fringe, L = 4 m
distance between central bright fringe and first dark fringe, y = 4 mm
Diffraction angle
Now.
m = 1
Answer;
A legislative body oversees city departments directly.
Explanation;
City commission government is a form of local government in the United States. In a city commission government, voters elect a small commission, typically of five to seven members, on a plurality-at-large voting basis.

Answer:
total amount of fluoride 3.6 *10^6 g
Explanation:
we know that
volume of reservoir 
=![\pi* [\frac{4.70*10^2}{2}]^2 *14.2](https://tex.z-dn.net/?f=%5Cpi%2A%20%5B%5Cfrac%7B4.70%2A10%5E2%7D%7B2%7D%5D%5E2%20%2A14.2)
= 2.25*10^6 m^3
denso=ity of water = 1000 kg/m3
mass of water = 1000*2.25*10^6
= 2.25*10^9 kg = 2.25*10^12 g
fluoride 1.6 ppm
total amount of fluoride 
= 3.6 *10^6 g
Answer:
A. Net force is 15 N.
B. The answer is given below.
Explanation:
The following data were obtained from the question:
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 NForce applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
A. Determination of the net force.
Force applied by you (Fᵧ) = 15 N
Force applied by your friend (Fբ) = 30 N
Net force (Fₙ) =?
Fₙ = Fբ – Fᵧ
Fₙ = 30 – 15
Fₙ = 15 N
Thus, the net force acting on the box is 15 N.
B. From the question given above, we can conclude that the box will move towards you because the force applied by your friend is greater than yours.
Answer:
50Kgm/s
Explanation:
Momentum=Mass*Velocity
P=mv
Given Mass=5Kg. Given Velocity=10m/s
Momentum=5*10=50Kgm/s
