Answer: 43.01 m
Explanation:
Given that :
Time ball uses in the air = 5.93, time it takes to reach maximum height and return = time of flight(T) = 5.93 s
TIME of flight (T) = 2 * time taken(t)
Where g = a = acceleration due to gravity = 9.8m/s²
S = 0.5at²
S = maximum height
Tjme taken (t) = time of flight / 2 = 5.93/2 = 2.965 s
Hence,
S = 0.5at²
S = 2 × 0.5 × 9.8 × 2.965²
S = 43.0770025
S = 43.01 m
Answer:
Frequency = 3 Hz
Explanation:
Frequency is a measure of Hertz. Recall that Hertz is the unit expressing cycles/second, where one second is the denominator of the fraction for simplicity. If there are 12 waves every four seconds, and one wave represents one cycle, dividing 12 waves by 4 seconds will give the answer of 3 waves (or cycles) per one second.
The cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.
What is Electric current?
The rate of flow of electric charge through a point is known as electric current. The electric current is nothing but the flow of electrons in general.
Consider a space, when electrons of charge (e) is flowing through the space in a given time interval t. Then,
I = e/t
here,
I is the electric current.
Moreover, there is a flow of electrons in a wire due to a potential difference existing at the circuit. Due to that, electrons always flow from high electric potential to low electric potential.
Thus, we can conclude that the cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.

The acceleration is the principal subordinate of the speed if the speed is steady the subsidiary is invalid if the speed is diminishing the subsidiary is negative. When discussing so much stuff we consider the momentary esteem.
<span>Note that when you back off, you back off by and large yet can locally in time quicken a tiny bit, suppose amid 1/tenth of a sec since you achieved a segment of the street which was slanting. In any case, this does not change the way that when the speed diminishes, the quickening is negative.</span>
