Answer:
The magnitude is
Explanation:
From the question we are told that
The distance between the spiders is
The charge on the is
The charge on is
Given that the charge are arranged in an equilateral triangle, it implies that the angle at each vertices of the triangle is 60°
Generally the magnitude of net force on is mathematically represented as
So
Here k is the columns constant with value
So
=>
From the diagram we see that
So
Now from the diagram the ls [tex]270^o[\tex] counterclockwise from x-axis
Answer:
Mass of ball = 3.0102 Kg.
Explanation:
Potential energy at height h is given by
PE = mgh
where m is the mass of the body
g is the the acceleration due to gravity whose value is 9.8 m/s^2
h is the height from surface level
PE is potential energy
In the problem given h = 2 meters
PE = 59 joules
59 = m*9.8*2
=> m = 59/9.8*2 = 3.0102 Kg
Thus, mass of ball is 3.0102 Kg.
Answer:
A wishing well is a term from European folklore to describe wells where it was thought that any spoken wish would be granted. The idea that a wish would be granted came from the notion that water housed deities or had been placed there as a gift from the gods.

Answer:
255 [m].
Explanation:
1) the formula is (d - requred distance, V₀ - initial velocity, t - elapsed time, a - deceleration):
2) according to the formula above the required distance is:
d=10*30-0.5*0.1*900=300-45=255 [m].

Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of kinetic energy, which is less than the initial amount of potential energy.
remember the law of energy there cannot be any more since it is using the potential energy to move
