What process contributes most to acid precipitation?

Physics
1 answer:
kramer3 years ago
7 0

Answer:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Look at the diagram below. The value of equivalent resistor is: A. 4 Ω B. 6 Ω C. 8 Ω D. 10 Ω
Advocard [28]

Answer:

R=4Ω

Explanation:

R1 and R3 are parrallel

so we have : R=R1*R2/R1+R2

R=6*3/6+3

R=18/9

R=2Ω

R2 and 2Ω are in series,so we have

R=R2+2

R=2+2

R=4Ω

A box-shaped metal can has dimensions 6 in by 2 in by 12 in high. All of the air inside the can is removed with a vacuum pump. A
leva [86]

Answer:

a) The total force is 4659.8 N

b) The gauge pressure is 50764 Pa

Explanation:

Given:

Pressure inside = 0

Patm = pressure outside = 1.013x10⁵Pa

Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa

a) The area is equal:

A=12*6=72in^{2} =0.046m^{2}

The force is:

F=delta-P*A=1.013x10^{5} *0.046=4659.8N

b) The gauge pressure at the bottom is equal:

P=\rho gh

Where:

ρ = density = 1000 kg/m³

h = 17 ft = 5.18 m

Replacing:

P=1000*9.8*5.18=50764Pa

15. A machine must move an object 15.1 meters by exerting a 121 Newton force. If the machine
Tcecarenko [31]

The power provided by the machine is 13.24 W.

Answer:

Explanation:

Power is determined as the ratio of work done by the system or on the system to the time interval. As the work done is equal to the product of force acting on the system or by the system with the  displacement experienced by the system. The power provided by the machine will be

Power = Work done /Time

As the force is given as 121 N and the displacement is given as 15.1 m in a time interval of 2.3 minutes. The time interval should be changed to seconds for each solving ability.

Time taken = 2.3 * 60 s = 138 s

Power = (121×15.1)/138 = 13.24 W.

So the power provided by the machine is 13.24 W.

Suppose that Paul D. Trigger fires a bullet from a gun. Will the speed of the bullet leaving the muzzle will be the same as the
Y_Kistochka [10]

Answer:

Explanation:

The speed of the bullet will only be the same if the mass of the bullet is equal to the mass of the gun. This because only their momentum ( product of mass and velocity) is conserved; the momentum before the gun and pullet was fired is equal to the momentum of the recoil of the gun and the momentum of the released bullet. The smallest mass  receives the highest speed (the bullet) while the larger mass ( the gun) receives the lowest speed ( speed of recoil).
