The force exerted by Earth plays the role of centripetal force.
Answer:
Explanation:
When standing sound wave is produced in a medium , distance between anti-node and next node is equal to a quarter of a wave length. Node is point of silence where sound intensity is zero or minima.
wave length = velocity / frequency
= 340 / 85
= 4 m
We must move by a distance of 4/4 = 1 m away from wall
to find the first quiet spot.
Answer:
5.0 km/h = 5.0 km/60min
speed = distance/time
distance = speed x time = 5.0km/60min x 19min = 1.6km

Answer:
Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. (HOPED THIS HELPED ;)
