I'm guessing that the question is how much force is pulling the two charges together. I'll use Coulomb's law where Force = k*Q1*Q2/r^2, where k is Coulomb's Constant= 8.99*10^9. First, r = distance between points = sqrt((0.150+0.15)^2+0^2) = 0.3 Entering this info into the equation = (8.99*10^9)*(6*10^-9)*(6*10^-9)/(0.3)^2 = 3.60*10^-6 Newtons away from each other They repel since both are positive).
Answer:
(a) K.E = 56000 J = 56 KJ, (b) d = 116.618 m
Explanation:
Given:
m = 70 Kg, Vi = 40.0 m/s, Vf= 0 m/s, μk = 0.70
Solution:
(a) K.E. =? J (due to motion of the runner the mechanical energy loss is in the form K.E.)
K.E. = 1/2 m v² = 0.5 ×70 kg × (40.0 m/s)²
K.E = 56000 J = 56 KJ
(b) distance d =? m
W= F × d
∴W = K. E = 56000 J and F= mg μk
K.E. = mg μk × d
so 56000 J = 70 kg × 9.8 m/s² × 0.70 × d
d = 116.618 m

The correct answer is option A. 1/4 times
This is because distance and force are inversely proportional

Answer: This phenomenon happens due to upthrust exerted by water.
Explanation:
We know that,
Liquid Pressure is directly proportional to the height of the vertical column in the liquid.(P∝h)
When a bucket filled water is sunk into the water container, there occur difference in the pressure in top and bottom of the water container. Due to this, water exerts an upward force on the bucket filled with water. This is called Uprthrust.
Upthrust on the bucket makes the bucket filled with water lose some of it's weight and causes apparent loss in weight.
Hence, the bucket filled with water seems light while it sinks into water.
C. slate cause bedrocks are the general medium for a seismic wave ,the conductivity depends on temp,density,element and tensition . generally its faster the densier, heavier , and more tense and what the element is.
