Answer:

0.007

Explanation:

A = F/P

Force = 1730

P = 2.45 = 2.47 * 10^5

1730/(2.47*10^5) = 0.007

Answer:

Hi.

The answer to this problem is 0.007

Explanation:

It was correct for Acellus

How to solve it:

P=F/A

Rearrange it for A, plug in the numbers and solve!

A=F/P

F=1,730

P=2.45

Which interaction between x-ray photons and matter results in total absorption of the incident photon?

Leno4ka [110]

Answer:

Photoelectric effect

Explanation:

In the photoelectric effect, when an x-ray strikes on a metal surface, the energy is completely absorbed by the metal. If the energy would be equal to or more than work function of metal, electron ejects out. The kinetic energy of the electron which is ejected depends on the energy of the incident radiation and work function of the metal.

Explain why atomic radius decreases as you move to the right across a period for main-group elements but not for transition elem

Aleksandr-060686 [28]

Answer:

Explained.

Explanation:

Only the first question has been answered

In a period from left to right the nuclear charge increases and hence nucleus size is compressed. Thus, atomic radius decreases.

In transition elements, electrons in ns^2 orbital remain same which is the outer most orbital having 2 electrons and the electrons are added to (n-1) d orbital. So, outer orbital electron experience almost same nuclear attraction and thus size remains constant.

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. A r

Illusion [34]

Answer:

the weight of the rider is 493.53 N

Explanation:

Given the data in the question and as illustrated in the image below,

Tension T = 1900 N

the rider is moving at a constant speed so the net force in the horizontal direction will be 0

In the horizontal direction

F $_{sail$ cos( 30° ) = Tcos ( 17° )

F $_{sail$ = Tcos( 17° ) / cos( 30° )

F $_{sail$ = 1900cos( 17° ) / cos( 30° )

F $_{sail$ = 2098.07 N

Now, In the vertical direction,

F $_{sail$ sin( 30° ) = W + T sin( 17° )

W = F $_{sail$ sin( 30° ) - T sin( 17° )

W = 2098.07sin( 30° ) - 1900sin( 17° )

W = 1049.035 - 555.506

W = 493.53 N

Therefore, the weight of the rider is 493.53 N
