Answer:

In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards.

The pressure at a depth in a fluid of constant density is equal to the pressure of the atmosphere plus the pressure due to the weight of the fluid, or p = p 0 + ρ h g , p = p 0 + ρ h g , 14.4

How does the water cycle influence weather in your area? Use complete sentences and a specific example from your experience.
Charra [1.4K]

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration.

As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins
Colt1911 [192]

Answer:

A. w=8.3rev/s

a_v=3.21rev/s^2

B. rev=10.79rev

Explanation:

A.

500rpm

500rpm*\frac{1minute}{60seg}=8.33\frac{rev}{s}

the time is about 2.60s knowing the acceleration is:

a_v=\frac{w}{t}

so:

w=8.3rev/s

a_v=\frac{8.33 rev/s}{2.60s}=3.21rev/s^2

B.

The CD stop so the final velocity is vf=0 so:

Total revolutions:

8.3rev/s*2.60s=21.58rev

21.58rev/2=10.79 rev

Dos cargas puntuales (q1 y q2 ) se atraen inicialmente entre sí con una fuerza de 550 N , si la separación entre ellas es de 90
antiseptic1488 [7]

Answer:

q2 = 9.02*10^{-4}C

Explanation:

To find the value of the other charge you use the Coulomb's law:

F=k\frac{q_1q_2}{r^2}

k: Coulomb's constant = 8.98*10^{9}Nm^2/C^2

q1: charge 1 = 55*10^{-6}C

r: distance between charges = 90cm = 0.9m

F: electric force = 550N

By doing q2 the subject of the formula and replacing you obtain:

q_2=\frac{r^2F}{kq_1}=\frac{(0.9m)^2(550N)}{(8.98*10^9Nm^2/C^2)(55*10^{-6}C)}=9.02*10^{-4}C

hence, the value of the other charge q2 is 9.02*10^{-4}C
