Answer from: yasarhan2

The correct answer is reflection.

Explanation:

Reflection is defined as bouncing back of the light rays from the shiny or mirror surface.

According to question when lights falls on the surface of metal cup it bounced towards Harold's eyes due to which light shines in his eyes.

Metals shows the property of luster and hence, their surface are lustrous surfaces. Therefore,phenomena of reflection is observed.

From the given options the correct answer is reflection.

Answer from: lahebra

Reflection and absorption

Explanation:

In ideal situation this shows reflection. Light falls on the metal cup and enters in Harold's eye due to reflection from the surface of the cup.

But the cup will not have the capacity to reflect 100% of incident light. Some part of the light is absorbed by the cup as well. So practically both absorption and reflection of light wave are happening in this scenario.

Answer from: Quest

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

$v_j = v_1 + v_2 = 3.100 + 1.350 = 4.45 m/s$

now the speed of paul will be same as it is given as he is running on the ground

$v_p = 3.100 m/s$

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

$\delta t = \frac{d}{v_j} - \frac{d}{v_p}$

$\delta t = \frac{2080}{4.450} - \frac{2080}{3.100}$

$\delta t = -203.55 s$

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ∆t. the resistance of the coil is r, and the total charge is q = i∆t, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly “swiped” past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be “swiped” through the reader at exactly the right speed? why or why not?
