We know that,
Mass of skier is <u>25</u> kg
Боже, как это сложно! Ну ладно.
Между прочим это ты сам должен делать, а то не куда не поступишь!
Answer:
C)the distance decreases Shorter wavelength
Step by step Explanation:
Answer:
U = 8.30×10-⁹J
Explanation:
m1 = m2 = 5.00kg masses of the spheres
d = 15.0cm = 15×10-²m
r = 5.10cm = 5.10×10-²m
R = d + r = 15×10-² + 5.10×10-²
R = 20.10 ×10-²m = 0.201m
G = 6.67×10-¹¹Nm²/kg²
U = Gm1×m2/R = potential energybetween the spheres
U = 6.67×10-¹¹×5.00×5.00/0.201
U = 8.30×10-⁹J
Hypotheses and theories related to each other since hypotheses are used in creating a theory. Hypotheses are explanations for some phenomenon that are still proposed. When these are validated and proved, they are accepted by the public as theories and are used to explain natural phenomenon.
