Physics

Sauron [17]1 year ago

From sea level to the top of the atmosphere, a column of air with a 1-m2 cross section weighs 101,000 N.

To find the answer we have to know about the pressure.

<h3>What is Pressure?</h3>
  • The pressure at a point on a surface is the thrust acting per unit area around that point.

                    Pressure, P=\frac{Thrust}{Area}=\frac{F}{A}

  • A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,

                   P=P_a=1.013*10^5 pascal

Pa is the atmospheric pressure at the sea level.

  • By combining both the equations, we get the weight of air,

                                       \frac{F}{A}=P_a

              F=W=P_a*A=1.013*10^5*1=101300N

Thus, we can conclude that, the weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is 101300N.

A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.2 m/s , a typical raindrop speed. How fast
netineya [11]

Answer:

The speed of the raindrop  and the mosquito is 8.02 m/s.

Explanation:

mass of mosquito = m

mass of drop = 45 m

initial velocity of mosquito, u = 0 m/s  

initial velocity of drop,  u' = 8.2 m/s

During the inelastic collision, the momentum of the system is conserved.  

Let the speed of rain drop and the mosquito is v.

Use the conservation of momentum

m x u + 45 m x u' = (m +  45 m) v

m x 0 + 45 m x 8.2 = 46 m x v

v = 8.02 m/s

A. A person does 5415J of work in 4.5 minutes, how much power, expressed in watts, rounded to the tenths place, was generated?
iris [78.8K]

Answer: I only have the answer for A, but still, the answer is 20.07.

  1. Explanation: Because the number ends in a 15, round to the nearest tenth which is 20. So now the number is 5420.
  2. To get the Watts (W) you have to take 5420 and divide it by the time in seconds. 4.5 minutes in seconds is 270, so 5420 divided by 270 equals 20.07.
  3. So 20.07 is the answer.

How does a series circuit differ from a parallel circuit?
nika2105 [10]

\large \sf{Answer :- }

\pink:\impliesIn a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component.

\pink:\impliesIn a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
