Hydrogen fuel cells is the answer
Answer:
M = ρ V = 9 gm/cm^ 3 * cm^3 = 27 gm
a = (V2 - V1) / t = (6 - 2) m/s / 12 s = 1/3 m/s^2 the acceleration
F = M a = 27 gm * 1/3 m/s^2 = 9 dynes net force applied
Answer:
The period of a mass m on a spring of spring constant k can be calculated as T=2π√mk T = 2 π m k .
Explanation:
4*5=20; ration of 20:25,
20/25= %80
