Answer:
Randell using a public computer is vulnerable to theft.
We should first calculate the highest point that ball reaches.
y' = 40 - 32t = 0
t = 40/32 = 1,25s
y = 25 feet.
To calculate average velocity we use simple formula:
Vav=s/t where s is traveled distance by the time t.
for t=2 we calculate y
y = 16
(i) for t = 2,5 y = 0
Vav = 16/0.5 = 32 feet/s
(ii) for t = 2.1 y = 13.44
Vav = 2.56/0.1 = 25.6 feet/s
(iii) for t = 2.01 y = 15.7584
Vav = 0.2416/0.01= 24.16 feet/s
it seems like the answer would be 24 feet/s. There is a way to calculate that.
If two wires run parallel and the current passes through
both wires in the same direction, which happens to the wires?
If two wires run parallel and the current passes through
both wires in the same direction, the wires wires move together because the
current of one wire pulls the other wire closer. The answer is letter C.
<h2> F = k×
</h2>
Explanation:
- The attractive or repulsive forces which act between any two charged species is an electric force.
- The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows
F = k×
where, K is coulombs constant, which is equal to - 9 x10^9 
- The unit for K is newtons square meters per square coulombs.
- This is known as Coulomb's Law.
