The amplitude and wavelength are measured in meters while frequency is measured in decibels.

<h2>Units of measurement:</h2>

Amplitude: It is the maximum displacement of the points of the wave from its mean position. Hence it is measured in meters.

Frequency: It is measured in Hertz. A hertz is a number of waves passed from a single point per second.

Wavelength: It is the distance between two consecutive crests or troughs. hence it is measured in meters.

Wave speed: It is measured in m/s.

Loudness: The loudness of the sound is measured in decibels.

Therefore, the amplitude and wavelength are measured in meters while frequency is measured in decibels.

How do they make pickle sunflower seeds?

Kobotan [32]

Preheat oven to 350°F. Spray large baking sheet with cooking spray.

Place dill, garlic powder, onion powder, salt, sugar and ascorbic acid in small bowl and stir to combine.

Generously season sunflower seeds with dill mixture and toss to combine. Taste and season again, if needed.

Arrange seeds on baking sheet and transfer to oven to brown for 10 to 15 minutes, tossing every 5 minutes to prevent burning.

Remove from oven, let cool and store in airtight container.

Express force in terms of base units

denis-greek [22]

Answer:

F = [MLT⁻²]

Explanation:

Force = ma

m (mass) = [M]

a (acceleration) = [LT⁻²]

F(force) = m x a = [MLT⁻²]

A batter hits a foul ball. The 0.14-kg baseball that was approaching him at 40 m/s leaves the bat at 30 m/s in a direction perpe

swat32

Answer:

7 kgm/s or 7 Ns

Explanation:

Since the velocity are perpendicular to each other, the impulses will also be perpendicular.

From newton's second law of motion,

Impulse = mass×velocity

I = mv............. Equation 1

For the horizontal,

I₁ = mv₁......... Equation 2

Given: m = 0.14 kg, v₁ = 40 m/s

Substitute into equation 2

I₁ = 40(0.14)

I₁ = 5.6 kgm/s

Also for the vertical,

I₂ = mv₂.............. Equation 3

Given: m= 0.14 kg, v₂ = 30 m/s

Substitute into equation 3

I₂ = 0.14(30)

I₂ = 4.2 kgm/s

Using Pythagoras to get the resultant impulse

I = √(I₁²+I₂²)................ Equation 4

Substitute the value of I₁ and I₂ into equation 4

I = √(5.6²+4.2²)

I = √(31.36+17.64)

I = √49

I = 7 kgm/s or 7 Ns

You were driving your car to UTD at a speed of 35 miles per hour. You stopped at the FloydCampbell intersection with the signal

ser-zykov [4K]

Answer:

green light have high energy

Explanation:

We have given the wavelength of the red light $\lambda =6.45\times 10^{-5}cm=6.45\times 10^{-7}m$

Speed of the light $c=3\times 106{8}m/sec$

The energy of the signal is given by $E=h\nu =h\frac{c}{\lambda }=\frac{6.67\times 10^{-34}\times 3\times 10^{8}}{6.45\times 10^{-7}}=3.1023\times 10^{-15}j$

The frequency of the green light is given by:

$f=5.80\times 10^{14}s^{-1}$

So energy $E=h\nu =6.67\times 10^{-34}\times 5.80\times 10^{14}=3.8686\times 10^{-19}j$

So green light have high energy
