Dmitry_Shevchenko [17]

Answer:

Explanation:

Let the charge on bead A be q nC  and the charge on bead B be 28nC - qnC

Force F between them

4.8\times10^{-4} = \frac{9\times10^9\times q\times(28-q)\times10^{-18}}{(5\times10^{-2})^2}

=120 x 10⁻⁸ = 9 x q(28 - q ) x 10⁻⁹

133.33 = 28q - q²

q²- 28q +133.33 = 0

It is a quadratic equation , which has two solution

q_A = 21.91 x 10⁻⁹C or q_B = 6.09 x 10⁻⁹ C

Centripetal Force, F = mv²/r

Where m = mass in kg, v = velocity in m/s and r = radius of curvature in m.

Centripetal Force, F = 2000 * 25² / 80.    Use your calculator.

                           F = 15 625 N.

A dolphin jumps out of the water. As it falls back down it a clerated at a rate of -9,8m/s^2 for 0.8 seconds of free fall. To ca
Anettt [7]

Answer:

0.196 m

Explanation:

Given in the question that,

time taken by the dolphin to go back to water = 0.2 sec

To solve the question we will use Newton's Law of motion

<h3>S = ut + 0.5(a)t²</h3>

here S is distance covered

u is initial speed

a = acceleration due to gravity

t = time taken

Plug value in the equation above

S = 0(0.2) + 0.5(-9.8)(0.2)²

S = 0.5(-9.8)(0.2)²

S = -0.196 m

Negative sign represent direction

(Assuming that dolphin have a vertical straight jump not a projectile motion)
