Water is a naturally abundant polar solvent that is essential for life as we know it. It consists of two hydrogen atoms covelently bonded to oxygen making a H-O bond angle of 120 degrees.

Answer:

Explanation: Water is a colorless, odorless and tasteless chemical substance which is made up of two molecules of oxygen and one molecule of hydrogen.Two third part of our planet is made up of water that is why earth is called a blue planet. Water is a polar solvent which is important for life. Water molecules are bounded with hydrogen bonds with each other. In polar form they exist as one hydrogen(positive ion) and one OH(negative) ion.

When a carpet is beaten with a stick dust comes out of it ...why
Mandarinka [93]

This can be explain through Newton’s first law of motion where an object at rest remain in rest unless acted upon by an unbalanced force. Hence, the dust particles having inertia and trapped within the pores of the carpet has the tendency to remain at the state of rest, it does not move and resist motion but when the carpet is beaten with a stick, dust comes out because the force from a stick acted upon it.

Find the equivalent resistance of this circuit
Phantasy [73]

Answer:

Req = 564 Ω

Explanation:

The equivalent resistance between R1 and R2:

1/R =1/R1 + 1/R2

1/R =1/960 + 1/640

1/R = 1/384

R = 384

Now, the equivalent resistance between R and R3:

Req = 384 + 180

Req = 564 Ω

What are barriers to physical fitness and activity?
vagabundo [1.1K]
Barriers to physical fitness and activity may be someone's health (they may have a disease that prevents them from exercising). Other than this, there really is no limit to whom can exercise.

Hope this helps!

Baseball scouts use a radar gun to measure the speed of pitches. One particular model of radar gun emits a microwave signal at a
SpyIntel [72]

Answer:

2.8\times 10^3 Hz

Explanation:

We are given that

Frequency,f=10.525GHz=10.525\times 10^9 Hz

Speed,v=40.2 m/s

We have to find the increase in frequency.

We know that

Speed of light,c=3\times 10^8m/s

\Delta f=f\times \frac{v}{c}

\Delta f=10.525\times 10^9\times \frac{40.2}{3\times 10^8}

\Delta f=1.4\times 10^3Hz

The waves are reflected therefore the change in frequency  at the gun is equal to twice the change in frequency.

Therefore, increase in frequency=2\Delta f=2\times 1.4\times 10^3=2.8\times 10^3 Hz
