In order to convert the ft^2 to m^2, we use the multiplier 0.09290304.
Therefore your calculation would be: 0.09290304 · 1930 = 179.303m^2 (rounded to 3 d.p)
Answer:
100 mph
Explanation:
Average speed = distance / time
v = 250 mi / 2.5 hr
v = 100 mi/hr
Newton's first law of motion is an object in motion stays in motion until acted upon by another force. Driving at 30 mph in a car is going to stay constant until you crash the car into a wall, stopping the car.
Answer:
Graph B shows the solubility of gas dissolved in a liquid.
In graph B the temperature is increasing and solubility decreases
So, when temperature increases the molecules of the gas becomes free their kinetic energy increases.
Hence, their solubility decreases they will be more present in the form of vapors.
Therefore, Option B is correct that is gas dissolved in a liquid.
Answer:
1.25Hz
Explanation:
For waves on a string, the second harmonic is obtained from;
2fo = 1/l √T/M
Where;
l = length of the string
M= mass in kilograms
T = tension in the string
2fo = 1/2√5/0.8
2f0 = 1.25Hz
