Answer
given,
mass of spring, m = 1.12 Kg
spring constant , k = 32.3 N/m
speed. v = 3.58 m/s
a) Kinetic energy of the spring
the mechanical work done by the spring
now,
A =0.666 m
Amplitude of Oscillation = 0.666 m
b) Total mechanical work done by the spring
E = 7.17 J
Answer:
95.47 C
Explanation:
Heat added = mass × heat capacity × rise in temperature
So, rise in temperature =
20000 / (0.05 × 4190)
Rise in temperature = 95.47 C
Sometime is the answer... hope I’ve help y’all
Answer
Force between two charged bodies q₁ and q₂ is given by the formula below.
F = Kq₁q₂/r²
Where k = constant
r = distance between them
F = (9.0 E9 × 1.0 E-6 × 1.0 E-6)/0.30²
= 9.0E-3/0.30²
= 9.0E-3/0.09
= 0.1 N
Because for that you need to build dams and other mega construction.. which is not possible for every country as they have many economical problems asli they have to be in large number to generate power which can feed the whole globe.. which is again difficult due to over population.
