Hey
in the summer it is because of the meting of snow
in the spring it is rain
hope l helped
Answer:
frequency = 5.52 * 10² Hz
Explanation:
the equation that relates velocity, frequency and wavelength is:
velocity = frequency * wavelength
We are given that:
velocity = 331 m/sec
wavelength = 0.6 m
Substitute with the givens in the equation to get the frequency as follows:
velocity = frequency * wavelength
331 = frequency * 0.6
frequency = 331 / 0.6
frequency = 5.52 * 10² Hz
Hope this helps :)
Answer:
a) 1.5 × 10² kPa
b) 16.9/8.1
Explanation:
a) The pressure of the front tires is 22 psi. The appropriate conversion factor is 1 psi = 6.89 kPa. The pressure of the tires in kPa is:
22 psi × (6.89 kPa / 1 psi) = 1.5 × 10² kPa
b) Regarding the blood pressure, the minimun reading is 61 mmHg and the maximum reading is 127 mmHg. The appropriate conversion factor is 1 kPa = 7.50 mmHg. The blood pressure in kPa is:
61 mmHg × (1 kPa / 7.50 mmHg) = 8.1 kPa
127 mmHg × (1 kPa / 7.50 mmHg) = 16.9 kPa
Answer:
first one is b 2nd one is a 3rd is c and the 4th one is c also
Explanation: have a nice day
Friction-reducing technologies used in the Variable Compression Turbo Engine are Diamond-like coating on valve lifters, micro finishing on crankshaft and camshaft and mirror bore coating on cylinder wall.
<u>Explanation:</u>
Variable compression is a technology to adjust the compression of an internal combustion engine while the engine is in operation. At this time friction may occur that need to be reduced. To reduce this friction some technologies are used like
- Diamond-like coating on valve lifters
- Micro finishing on crankshaft and camshaft
- Mirror bore coating on cylinder wall
A hydrogen free diamond like carbon coating is applied to an engine valve lifter to reduce mechanical loss. Micro finishing on crankshaft and camshaft achieves improvement in geometric parameters such as roundness. Mirror bore coating on cylinder wall raises energy efficiency by reducing the friction inside the engine.
