Answer:

Two wave will be coherent when they have the wavelength, amplitude, and phase of the constituent wave forms must be identical.

Where as interference is the addition of two wave considering the mathematical sense while adding them.

when two wave of same sense add together they for constructive interference. like two +ve sense or -ve sense will form constructive interference.

when the are are of different sense the form destructive interference. like one positive wave added with -ve one.

A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio

Gnesinka [82]

Answer:

a). $a_p=-2.39x10^{-12} rad/s^2$

b). $t=1016298.8 years$

c). $T_i=80.58x10^{-3}s$

Explanation:

a).

The acceleration for definition is the derive of the velocity so:

$a_p=\frac{dw}{dt}$

$w=\frac{2\pi}{t}$

$a_p=\frac{dw}{dt}=-\frac{2\pi}{t^2}*\frac{dT}{dt}$

$dT=0.0808s$

$dt=1 year*\frac{365d}{1year} \frac{24hr}{1d} \frac{60minute}{1hr} \frac{60s}{1minute}=31.536x10^{6}s$

Replacing

$a_p=-\frac{2\pi}{0.082s^2}*\frac{9.84x10^{-7}}{31.536x10^{6}s}= -2.39x10^{-12} rad/s^2$

b).

If the pulsar will continue to decelerate at this rate, it will stop rotating at time:

$t=\frac{w}{a_p}$

$w=\frac{2\pi }{t}=\frac{2\pi }{0.0820s}=76.62 rad/s$

$t=\frac{76.62 rad/s}{2.39x10^{-12}rad/s^2}= 3.2058x10^{13}s$

$t=1016298.8 years$

c).

A tube has a length of 0.025 m and a cross-sectional area of 6.5 x 10-4 m2. The tube is filled with a solution of sucrose in wat

Pepsi [2]

Answer:

The time required for sucrose transportation through the tube is 8.4319 sec.

Explanation:

Given:

L = 0.025 m

A = 6.5×10^-4 m^2

D = 5×10^-10 m^2/s

ΔC = 5.2 x 10^-3 kg/m^3

m = 5.7×10^-13 kg

Solution:

t = m×L / D×A×ΔC

t = (5.7×10^-13) × (0.025) / (5×10^-10)×(6.5×10^-4)×(5.2 x 10^-3)

t = 8.4319 sec.

WhAt is this question??????????

valina [46]

Answer:

Period = 7

Group = Actinides group

Family = Actinides Family

Explanation:

uranium found in seventh row or seventh period of the periodic table.

uranium is the member of Actinoides group it is also called Actinide group, And it has element whose atomic is number is 89 to 103. The atomic number of the uranium is 92. So, the uranium element is belongs to Actinide group

Uranium found in actinide family of periodic table, and actinides family has element whose atomic number is greater than or equal to 89 and less than or equal to 103.

At which latitudes shown in the image of Earth do people experience the greatest tangential speed?

PilotLPTM [1.2K]

There's actually only one latitude implied by anything attached the question . . . Zero, since there are no choices listed.

That's brilliant ! Because zero latitude (the equator) IS the place on Earth where tangential speed is greatest.

Very clever !
