Answer:
B= 100 N
Explanation:
Given data:
Mass of ball = 0.05 Kg
Acceleration of ball = 2000 m /s²
Net force = ?
Solution:
Formula:
F = ma
F = force
m = mass
a = acceleration
By putting values,
F = 0.05Kg × 2000 m/s²
N = Kgm/s²
F = 100 N
The horizontal distance represents wavelength λ. The time represents the period of the wave T.
Wave speed is given by v= λ/T
Hence, those are the only parameters needed.
Note: the vertical distance is for calculating amplitude which is not used in calculating wave speed.

Answer:
2.47 M
Explanation:
Molarity is (mol of solute)/(L of solvent). To find molarity, convert grams of NaCl to moles of NaCl and milliliters of water to liters of water.
72.3 g ÷ 58.44 g/mol = 1.2372... mol
500 mL ÷ 1000 mL = 0.5 L
Molarity = 1.2372/0.5 = 2.47 M
