Explain please explain

Answer 1

Answer:

1=Speed=500 km/hr

Time=15 minutes

1 hr=60 min

15 min=1/4hr

Distance =speed×time

distance=500×1/4

Distance=125 Km

2=Time=25seconds

Complete oscillations =20

Time period for each pendulum=20/25

Time for each oscillation=1.25

3=Distance=450Km

Time=6hr

Speed=Distance/Time

Speed=450/6=75 km/hr
