First, we need to find the spring constant
Force of gravity = force of tension from spring
mg = kx
(1x10^-3)(9.8) = k (3.2x10^-2)
k = .30625
Now we can look at the other situation
Since the spring was moved 0.01 meters, we can find the force
F = kx = (.01)(.30625) = .0030625 N
Now we can set the electric force equal to the force of the beads
kq^2/r^2 = .0030625 N
q = 292 microCoulombs
Answer:
The sun
Explanation:
if they get too close even the heat that radiates of of it would burn you or give sunburn bad and the sun is a shining ball of energy it is way to hot for a human to get close
The velocity of the watermelon as it hits the ground is 14.715 m/s.
Given the data in the question;
Since the Watermelon was dropped from rest,
- Initial velocity of the Watermelon;
- Time taken for the Watermelon to hit the ground;
- We know that, Acceleration due to gravity;
Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.
From the First Equation of Motion:
Now, under gravity, acceleration ''a" will Acceleration due to gravity;
, "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.
So, we substitute our values into the equation
Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

To get the number of unstable atoms:
Column 3: take 900 - 90 = 810 The numbers from column 2
To get the Number of decayed atoms:
take the 810 * 10% = 810 * .1 = 81
Follow the pattern for the rest of the table.
