Answer:

oh this one is easy its the rotation of earth (how fast its rotating) and the height of the waves meaning the higher the wave the faster the current moves, the lower the wave the slower the current moves.

18. A circuit contains a 10 ohm resistor, a 50 ohm resistor, and an 80 ohm resistor connected in parallel. If you test this circ

lutik1710 [3]

The equivalent resistance is D) $7.55 \Omega$

Explanation:

The equivalent resistance of n resistors in parallel is given by the equation:

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+...+\frac{1}{R_n}$

For three resistors such as in this problem, the equation becomes

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}$

where we have the following:

$R_1 = 10 \Omega$ is the resistance of the 1st resistor

$R_2 = 50 \Omega$ is the resistance of the 2nd resistor

$R_3 = 80 \Omega$ is the resistance of the 3rd resistor

Substituting, we find the equivalent resistance:

$\frac{1}{R}=\frac{1}{10}+\frac{1}{50}+\frac{1}{80}=0.133 \Omega^{-1}$

$R=\frac{1}{0.133}=7.55 \Omega$

An object in a fluid experiences a buoyant force from the fluid. If the object is completely immersed, on which does the magnitu

loris [4]

Answer:

Weight of the fluid that the object displaces.

Explanation:

When the fluid is completely immersed in a fluid, it experiences pressure from all the direction. While the object is immersed in the fluid a force acts on it in the opposite direction, i.e., upwards. This force is termed as buoyant force.

Also, as per the Archimedes' Principle, the force experience by the object is the same as the weight of the fluid that gets displaced by the object.

Thus on complete immersion of the object in the fluid, it experiences the force same as the weight of the fluid that gets displaced

the frequency of a beam of uv light is 1.0 ×10 ^15hz what is the energy in one quantum of this light express it in ev?

kap26 [50]

Answer:

4.14 eV

Explanation:

f = 1.0 ×10^15 Hz

h= 6.63×10^-34 J s ( this is called PLANCK 'S CONSTANT)

ENEGY = E = ?

E = hf ( THIS IS FORMULA FOR ENERGY OF ONE QUANTA OR ONE PHOTON )

E= 6.63×10^-34×1.0 ×10^15

E = 6.63×10^-19 J

As 1eV = 1.6×10^-19 J so changing energy in eV from joules we will divide energy by 1.6×10^-19

hence E in eV = 6.63×10^-19/(1.6×10^-19)

E = 4.14 eV

arlik [135]

The statement 'establishing a high critical value in a statistical test is associated with more confidence' is TRUE.

<h3>What is statistical significance?</h3>

The statistical significance is a arbitrary value used to indicate that data collected can be used to confirm (or reject) my working hypothesis.

The most widely used value to measure the statistical significance is the p threshold.

In conclusion, the statement 'Establishing a high critical value when calculating the results of a statistical test means that a researcher will have more confidence in finding significance than when a lower critical value is established' is TRUE.
