lana [24]

Answer:8.28 km

Explanation:  

Given

First it drifts 45^{\circ} 2.5 km

r_1=2.5cos45 i+2.5sin45 j

Secondly it drifts 60^{\circ} 4.70 km

r_{12}=4.7cos60 i-4.7sin60 j

After that it drifted along east direction 5.1 km

r_{23}=5.1 i

After that it drifts 55^{\circ} 7.2 km

r_{34}=-7.2cos55 i-7.2sin55 j

After that it drifts 5^{\circ} 2.8 km

r_{54}=-2.8cos5 i+2.8sin5 j

r_{5O}=\left [ 2.5cos45+4.7cos60+5.1-7.2cos55-2.8cos5\right ]\hat{i}+\left [ 2.5sin45-4.7sin60-7.2sin55+2.8sin5\right ]\hat{j}

r_{5O}=2.299\hat{i}-7.95\hat{j}

|r_{5O}|=8.28 km

for direction

tan\theta =\frac{7.95}{2.299}=3.4580

\theta =73.87^{\circ} south of east

The bright yellow light emitted by a sodium vapor lamp consists of two emission lines at 589.0 and 589.6 nm. What are the freque
stiv31 [10]

Answer:

Explanation:

Given

wavelength of emissions are

\lambda _1=589 nm

\lambda _2=589.6 nm

Energy is given by

E=\frac{hc}{\lambda }

where h=Planck's constant

x=velocity of Light

\lambda=wavelength of emission

E_1=\frac{6.626\times 10^{-34}\times 3\times 10^8}{589\times 10^{-9}}

E_1=3.374\times 10^{-19} J

E_1 in kJ/mol

E_1=203.2 kJ/mol

frequency corresponding to this emission

\nu =\frac{c}{\lambda }

\nu _1=\frac{3\times 10^8}{589\times 10^{-9}}

\nu _1=5.09\times 10^{14} Hz

Energy corresponding to \lambda _2

E_2=\frac{6.626\times 10^{-34}\times 3\times 10^8}{589.6\times 10^{-9}}

E_2=3.371\times 10^{-19} J

E_2=203.02 kJ/mol

frequency corresponding to this emission

\nu =\frac{c}{\lambda }

\nu _1=\frac{3\times 10^8}{589.6\times 10^{-9}}

\nu _1=5.088\times 10^{14} Hz

What happens to the equilibrium price and quantity for jelly when the price of peanut butter increases? (Assume that peanut butt
Darya [45]

Answer:

Equilibrium price will fall and quantity demanded for jelly will also fall

<u>Explanation:</u>

Peanut butter and jelly are consumed together. It means they are complementary goods. These are those goods which are bought together. So increase or decrease in the price of one commodity will automatically affect the demand for another commodity.

When the price of peanut butter increases than people will demand less of peanut butter. Similarly, the demand for jelly is associated directly with the demand for peanut butter. So it will also fall . Due to the fall in the price of jelly and simultaneous fall in demand, the equilibrium price will fall.
