Thermometer
Explanation:
Hence the name Thermo meaning heat.
Answer:
<u>Conservation</u>: using less water
<u>Xeriscaping</u>: replanting your yard with plants that do not require great amounts of water
<u>Desalination</u>: process of removing salt from water so that it can be used for consumption
<u>Water Budget</u>: finite amount of usable water available
<u>Potable</u>: water that is safe to use a drink
<span>Every 10s 5 waves; t1 = 2s for each wave
When v = 1.5m/s, 3 waves in 10s t2 = 10 / 3s
Calculating the frequency in first case f1 = 5 / 10 = 0.5
Calculating the frequency in second case f2 = 3 / 10 = 0.3
Using the Doppler formula f = (1-v/c) f0
For the formula f = f2, v = velocity of boat= 1.5 m/s, f0 = f1, c is velocity of wave
0.3 = 0.5 x (1 - 1.5/c) => 1.5/c = 1 - 0.6 => 1.5/c = 0.4 => c = 1.5/0.4
Velocity of the wave = 3.75 m/s</span>
Answer:
Weight of an object = 225 newtons
Explanation:
Given:
Mass = 60 kilograms
Acceleration due to gravity = 3.75 m/s²
Find:
Weight of an object
Computation:
Weight of an object = Mass x Acceleration due to gravity
Weight of an object = 60 x 3.75
Weight of an object = 225 newtons
