Answer:
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen, and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Explanation:
Answer:
2.9Ω
Explanation:
Resistors are said to be in parallel when they are arranged side by side such that their corresponding ends are joined together at two common junctions. The combined resistance in such arrangement of resistors is given by;
1/Req= 1/R1 + 1/R2 + 1/R3 .........+ 1/Rn
Where;
Req refers to the equivalent resistance and R1, R2, R3 .......Rn refers to resistance of individual resistors connected in parallel.
Note that;
R1= 6.0Ω
R2 = 9.0Ω
R3= 15.0 Ω
Therefore;
1/Req = 1/6 + 1/9 + 1/15
1/Req= 0.167 + 0.11 + 0.067
1/Req= 0.344
Req= (0.344)^-1
Req= 2.9Ω
The realtionship between force in Newtons, mass in kilograms and acceleration in metres per second squared is described by Newton's second law of motion which is Force = mass times acceleration, or F=ma. You need to know the mass, so rearrange the formula to solve for m, giving m=F/a
In your example, the mass is therefore 8480 divided by 32, which is equal to 265kg.
Answer:
4.55 m/s
Explanation:
The frequency is defined as the number of rotations in one second
So, f = 2.03 Hz
r = 0.357 m
The tangential speed is
v = r ω = r x 2 x 3.14 x f = 0.357 x 2 x 3.14 x 2.03 = 4.55 m/s
<span>Como sabemos a quantidade de tempo que leva a Fernando para chegar à escola, quando sua classe começa e termina, e quanto tempo leva para chegar em casa, podemos resolver quanto tempo Fernando estava longe de casa. O que fiz primeiro foi adicionar os 40 minutos que levou Fernando para chegar em casa às 11:30 e chegou às 12:10. Foi quando Fernando chegou em casa, então tudo o que precisamos fazer agora é fator em 6:30 e descubra quanto tempo ele estava fora da casa. Eu fiz isso contando as horas e subtraindo os minutos extras. O tempo que Fernando acabou é de 5 horas e 40 minutos.</span>
