Answer:

V=21V

Explanation:

In series combination current is same

I=2.6A

R2=8ohm

V2=2.6×8

V2=20.8

V2=21V

Sort the chemical equations based on the chemical reactions they represent.

Svetradugi [14.3K]

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,

ABC → A + B + C

Specific Examples are as,

Water → Hydrogen + Oxygen

2 H₂O → 2 H₂ + O₂

Calcium carbonate → Calcium oxide + Carbon dioxide

CaCO₃ → CaO + CO₂

While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,

A + B + C → ABC

Specific Examples are as,

Iron + Oxygen → Iron Oxide

2 Fe + 3 O₂ → 2 Fe₂O₃

Sodium + Chlorine → Sodium chloride

2 Na + Cl₂ → 2 NaCl

Sulfur + Oxygen → Sulfur dioxide

S + O₂ → SO₂

Potassium + Chlorine → Potassium chloride

2 K + Cl₂ → 2 KCl

Ocean waves are hitting a beach with a frequency of 0.100 Hz. Their average wavelength is 15.0 m. What is their average speed?

den301095 [7]

Answer:

Average speed=1.5 m/s

Frequency of pendulum=93.75Hz

Explanation:

We are given

Frequency, $f=0.100Hz$

Average wavelength = $\lambda=15m$

Speed of pendulum, $v=30m/s$

Wavelength, $\lambda'=0.32m$

We have to find the average speed and frequency of pendulum.

We know that

Speed, $v=\lambda f$

Using the formula

Average speed, $v=15\times 0.1=1.5m/s$

Hence, the average speed =1.5m/s

Frequency, $f=\frac{v}{\lambda'}$

Using the formula

$f=\frac{30}{0.32}$

$f=93.75Hz$

Hence, the frequency of a pendulum=93.75Hz

What are 3 criteria for acceleration?

Temka [501]

I don't think you mean 'criteria'. I think you mean three occurrences or
observations that indicate the presence of acceleration.

They are:

-- an object is speeding up
-- an object is slowing down
-- the direction of an object's motion is changing .

Any one of these changes is acceleration.

There's a single term that covers them all. It is "change in velocity".

A certain electromagnetic wave traveling in seawater was observed to have an amplitude of 98.02 (V/m) at a depth of 10 m, and an

maksim [4K]

Answer:

The value is $\alpha = 0.002 Np/m$

Explanation:

From the question we are told that

The first amplitude of the wave is $E_{max}1 = 98.02 \ V/m$

The first depth is $D_1 = 10 \ m$

The second amplitude is $E_{max}2 = 81.87 \ (V/m)$

The second depth is $D_2 = 100 \ m$

Generally from the spatial wave equation we have

$v(x) = Ae^{-\alpha d}cos(\beta x + \phi_o)$

=> $\frac{v(x)}{v(x)} =\frac{ Ae^{-\alpha d}cos(\beta x + \phi_o)}{ Ae^{-\alpha d}cos(\beta x + \phi_o)}$

So considering the ratio of the equation for the two depth

$\frac{A}{A_S} = \frac{e^{-D_1 \alpha }}{e^{-D_2 \alpha }}$

=> $\frac{98.02}{81.87} = \frac{e^{-10 \alpha }}{e^{-100 \alpha }}$

=> $\alpha = \frac{0.18}{90}$

=> $\alpha = 0.002 Np/m$
