Explanation :

Scientific notation is the form of writing a very large or very small number in a simplest way.

Any number in scientific notation is written in the following form :

a\times 10^b

Where,

a is the coefficient of real numbers

b is any integer

In the given question, the number is given as 0.000681

So, in scientific notation it is written as 6.81\times 10^{-4}

Hence, this is the required solution.

What is the difference between sounds that have the same pitch and loudness? the standing wave the natural frequency the sound q
Elden [556K]

Answer:

Sound quality

Explanation:

Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.

Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.

How much heat is needed to raise the temperature of 100 g of water by 50 C, if the specific heat of water is 4,184 J/kg.C?
Yuliya22 [10]

Heat required to raise the temperature of water is given as

Q = ms\Delta T

here we have

m = 100 g = 0.100 kg

s = 4183 J/kg C

\Delta T = 50 ^0 C

now we can use the above equation

Q = 0.100 * 4184 * 50

Q = 20920 J

so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C

Two skiers start at the same place at the top of the hill, and finish at the same place at the bottom. Skier A takes a straight,
Rus_ich [418]

Answer:A

Explanation:

Given

Skier A takes straight, smooth route while Skier B takes curvy, bumpy route to finish.

We know gravity is conservative in nature i.e. work done against it is independent of path followed

So work done by gravity for A and B is same

According to Work energy Theorem Change in the kinetic Energy is equal to work done by all the forces.

W_g=\frac{1}{2}mv^2

W_g=mgh

where h=vertical height of hill

thus v=\sqrt{2gh}

which is same for both A and B

Am radio signals are broadcast at frequencies between 550 khz and 1600 khz and travel 2.99792 × 108 m/s. What is the shortest am
Rus_ich [418]

Answer:

187.37 m

Explanation:

The wavelength of an electromagnetic wave is given by:

\lambda=\frac{c}{f}

where

c is the speed of light

f is the frequency

We see that the wavelength is inversely proportional to the frequency: this means that the shortest am wavelength will occur at the highest am frequency, which is

f=1600 kHz = 1600 \cdot 10^3 Hz

And substituting also the speed of light

c=2.99792 \cdot 10^8 m/s

We find the wavelength:

\lambda=\frac{2.99792 \cdot 10^8 m/s}{1600\cdot 10^3 Hz}=187.37 m
