spin [16.1K]3 years ago
4 0

Answer:

The main difference between friction and viscosity is that friction is used to refer to forces that resist relative motion, in general, whereas viscosity refers specifically to resistive forces that occur between layers of a fluid when fluids attempt to flow.

Frequency of the wave below?
agasfer [191]

It's hard to tell exactly what's happening in that 110 cm that you marked over the wave. What is under the ends of the long arrow ? How many complete waves ? I counted 4.5 complete waves ... maybe ?

If there are 4.5 complete waves in 110cm, then the length of 1 wave is (110/4.5)=24.44cm.

Frequency = speed/wavelength

Frequency = 2m/s /0.2444m

Frequency = 8.18 Hz

Answer:

A_{area}=0.243m^{2}

Explanation:

Given data

Average intensity of sunlight on one day I=700 W/m²

Power P=170 W

To find

Area A

Solution

As we know that:

I_{intensity}=\frac{P_{power}}{A_{area}}\\ A_{area}=\frac{P_{power}}{I_{intensity}}  \\ A_{area}=\frac{170W}{700W/m^{2} } \\ A_{area}=0.243m^{2}

Joanna drove a car at 30km/hr. What is the speed in m/s?
Aloiza [94]
8.33 m/s
Explain:

If you understand what 1 km = 1000 m and 1 hr = 60*60 seconds signify, you already know what they mean. If you translate 1000 m/ 3600 s to km/hr, you'll get 5 m/ 18 s, which you can multiply by 30 to get (30 x 5)/18 = 8.33 m/s.
