<h3>Calculations and Parameters</h3>
Given;
- Frequency= 256 Hz
- Water level= 30cm
- Position of resonance= 100cm
- The velocity of sound in air= ?
v= 2f(L2-L1)
= 2.2.56.(1- 0.3)
=358 m/s

The object will sail away in a straight line ... continuing in the same direction it was going when the centripetal force stopped.
Answer:
A. If two objects collide, each object exerts a force in the same direction as the other.
Explanation:
Answer:
Answer:
15.67 seconds
Explanation:
Using first equation of Motion
Final Velocity= Initial Velocity + (Acceleration * Time)
v= u + at
v=3
u=50
a= - 4 (negative acceleration or deceleration)
3= 50 +( -4 * t)
-47/-4 = t
Time = 15.67 seconds
The flow of an alternating current switches direction when a generator's terminals change its charge is true regarding current in an external circuit
<u>Explanation:
</u>
Two types of currents, one of them is direct current (DC), constant charging current in one direction. The current in the DC circuits shifts in a constant direction. The amount of electricity can vary, but it always flows from one point to another.
Next is alternating current (AC), the movement of the electric charge periodically changes direction. It is the form most often provided to enterprises and households. The usual form of AC wave is the sine wave. Some applications use different wave-forms, e.g. B. triangular or square waves.
