- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And
- Hence force varies directly with acceleration hence weight will be more .
Answer:
Explanation:
The time constant of the radioactive isotope is:
The isotope decay is predicted by the following model:
The age of the rock is determined after algebraic handling:
Answer:
Explanation:
(i) μs = F/N = mgsinθ/mgcosθ = tanθ
tanθ = 0.3
θ = 16.7°
(ii) a = F/m
a = (mgsinθ - (μk)mgcosθ) / m
a = g(sinθ - (μk)cosθ)
a = 9.8(sin16.7 - (0.2)cos16.7)
a = 0.94 m/s²
(iii) s = ½at²
t = √(2s/a)
t = √(2(1)/0.94)
t = 1.5 s
The solution for this problem is computed by through this formula, F = kQq / d²Plugging in the given values above, we can now compute for the answer.
F = 8.98755e9N·m²/C² * -(7e-6C)² / (0.03m)² = -489N, the negative sign denotes attraction.
