Answer:
Given:
Mass of oxygen (m) = 32.0 g = 0.032 kg
Volume occupied by oxygen (V) = 22.4 L = 0.0224 m³
Speed of sound in oxygen (v) = 317 m/s
To Find:
Bulk modulus of oxygen
Explanation:
Answer:
<h3> B. 4 m/s</h3>
Explanation:
The formula for Speed is distance per time.
<h3>Therefore Speed = Distance / Time</h3>
<u>Data</u>
D = 40 m
T = 10 sec
S = ?
<h3> Speed = 40m /10sec</h3>
To find the speed , divide the distance by the time.
Note : the unit for Speed is meter /second
<h3> Speed = 4 m/s</h3>
Therefore the speed of the wave, the surfer is riding on is 4 m/s.
Answer:
B. in both directions until the temperature is equal in the water and the air
Explanation:
When a warm body is in contact with a cool body , there is exchange of heat energy in both sides until there is attainment of equilibrium temperature . At this temperature both the body attains equal temperature . Initially rate of heat radiated by warm body is more than that from cool body , but after attainment of equilibrium , the rate becomes equal to each other . This is called dynamic equilibrium .
Hence option B is correct .
