The distance travelled by the ball that is thrown horizontally from a window that is 15.4 meters high at a speed of 3.01 m/s is 5.34 m
s = ut + 1 / 2 at²
s = Distance
u = Initial velocity
t = Time
a = Acceleration
Vertically,
s = 15.4 m
u = 0
a = 9.8 m / s²
15.4 = 0 + ( 1 / 2 * 9.8 * t² )
t² = 3.14
t = 1.77 s
Horizontally,
u = 3.01 m / s
a = 0 ( Since there is no external force )
s = ( 3.01 * 1.77 ) + 0
s = 5.34 m
Therefore, the distance travelled by the ball before hitting the ground is 5.34 m

Answer:
Parallel circuit
Explanation:
A parallel circuit is a closed circuit in which current flows and divide in two or more paths and recombining to complete the circuit, each load (light bulb) receives the fully voltage of the batteries in the circuit.
Answer:
A theory does not change into a scientific law with the accumulation of new or better evidence. A theory will always remain a theory
Explanation:
Answer:
Thermometer calibration is the act of verifying whether your thermometers are reporting the correct temperature.
The answer is
in (m/s) : 100m / 9.77s = 10.2354 m/s
in (km/h) : (100/1000 or 0.1) km / (9.77/3600 or 0.002714) h = 36.84 km/h
in (ft/s) : 33.5807 ft / s
in mi / h : 22.8959 mi / h
