A swimming duck paddles the water with its feet once every 1.6 s, producing surface waves with this period. The duck is moving a

emmainna [20.7K]

Answer:

0.245 m/s

0.904 m

Explanation:

$v_{d}$ = speed of duck ahead of wave

$v_{s}$ = speed of surface wave = 0.32 m/s

T = time for paddling = 1.6 s

d = spacing between the waves = 0.12 m

speed of duck ahead of wave is given as

$v_{d}$ = $v_{s}$ - $\frac{d}{T}$

$v_{d}$ = 0.32 - $\frac{0.12}{1.6}$

$v_{d}$ = 0.245 m/s

$v_{w}$ = speed of wave behind the duck

speed of wave behind the duck is given as

$v_{w}$ = $v_{s}$ + $v_{d}$

$v_{w}$ = 0.32 + 0.245

$v_{w}$ = 0.565 m/s

D = spacing between the crests

spacing between the crests is given as

D = $v_{w}$ T

D = (0.565) (1.6)

D = 0.904 m

Object C has a mass of 3,600 kilograms. Object D has a mass of 900 kilograms. Both objects were placed on different planets so t

jek_recluse [69]

The answer is 1/4
this is actually a very simple question because if you divide 3,600 by 4 that equals 900 so if you want them to be the same waight you need 3,600 to be multiplied by 1/4.

To find the pressure with a given data for the height, you are asked to get the hydraulic pressure. Hydraulic pressure has the following formula:

P = density*acceleration due to gravity*height

Assume that the density of seawater is the same as that for pure water,density = 1000 kg/m^3.

P = 1000 kg/m3*9.81m/s2*9100m
P = 89271000 Pascals or 89.271 megapascals

Assume that the pictured magnet is being moved into the solenoid. If the polarity of the magnet is reversed and then moved into

dangina [55]

Answer:

The direction of the induced emf is revered, and hence the direction of the induced current.

Explanation:

When the polarity of the magnet is revered, the direction of the magnetic field is also reversed, and therefore, according to Faraday's law

$\varepsilon = NA\dfrac{dBcos(\theta)}{dt}$

$\varepsilon = -NA\dfrac{dBcos(\theta)}{dt}$

since the magnetic field changes sign from $B$ to $-B$ .

Hence, the effect is that the direction of the emf induced is reversed, which also reverses the direction of the induced current in the solenoid.

P.S:<em> The cause of confusion here is the direction of magnetic field lines from the magnetic</em>, and so you must remember that <em>field lines begin at the north pole and end at the south pole.</em>
