As compared with lower kVp exposures, when using high kVp will result in a scattered photon that is of ________ energy. Group of answer choices

Answers

Answer 1

Answer:

Increased

Explanation:

kVp is an acronym for kilovoltage peak, and it determines the strength x-ray beam strength, and the quality of the beam, it is a measure of the highest that the x-ray machine produces. A 60 kVp x-ray will produce photons with a maximum energy of 60 kilovolts while a 70 kVp will produce photons having 70 kilovolts as the maximum energy

Therefore, a high kVp exposure will result in scattered photon that is of increased energy compared with a lower kVp exposure.

How long will it take a 6000W motor to lift a 5000kg load through a height of 2.5m?

Answers

Answer:

20.4375 seconds.

Explanation:

Wattage = Work / time

Work = f * d

F = mass * acceleration

mass = 5000 kg

acceleration = force of gravity

acceleration = 9.81

Force = 5000 * 9.81

Force = 49050 N

Work = F * d

d = 2.5

Work = 49050 * 2.5

Work = 122625 Joules

Wattage = Work / time

time = work / wattage

wattage = 6000 watts

time = 122625 / 6000

time = 20.4375 seconds.

There is the more role of the moon than the sun to occur tides in the oceans,why?

Answers

Answer:

The ocean tides on earth are caused by both the moon's gravity and the sun's gravity. ... Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.

The moon plays a larger role than the sun in causing tides in the oceans because it is much closer to Earth and has a stronger gravitational pull on our planet. The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them.

Although the sun is much larger than the moon, its gravitational pull on Earth is much weaker because it is much farther away. The moon, on the other hand, is much smaller than the sun, but it is much closer to Earth and exerts a stronger gravitational force on our planet. This gravitational force causes the water in the oceans to bulge towards the moon, causing high tides.

In addition to the gravitational force, the shape of the ocean basins, the rotation of the Earth, and the positions of the sun and moon also play a role in causing tides. However, the moon's gravitational force is the primary factor that causes tides in the oceans.

The plane of a5cm*8cm rectangular loop of wire is parallel to a 0.19T magnetic field the loop carries a current of 6.2 A. What torque acts on aloop? What is the magnetic moment of the loop?

Answers

Answer:

Torque; τ = 4.712 × 10^(-3) J

Magnetic moment; M = 0.0248 J/T

Explanation:

Torque is gotten from the formula;

τ = BIA

Where;

B is magnetic field

I is current

A is area

We are given;

B = 0.19T

I = 6.2A

Rectangle dimensions = 5cm by 8cm = 0.05m by 0.08m

Thus;

Area; A = 0.05m × 0.08m = 0.004 m²

Thus;

τ = 0.19 × 6.2 × 0.004

τ = 4.712 × 10^(-3) J

Formula for the magnetic moment is given by;

M = IA

M = 6.2 × 0.004

M = 0.0248 J/T

What unit is used to measure the period of a wave?
A. Seconds
B. Meters
C. Hertz
D. Meters/second

Answers

Answer:

D. Meters/Seconds

Explanation:

The time period of a wave is measured in seconds.

A typical wave involves both time and distance.  Consider a sound wave, which is basically a periodic modulation of the local air pressure.  We "hear" the sound because our ears respond to the variations of pressure.

The most common metric of a sound wave is frequency.  This is the rate at which the change in pressure occurs, and is measured in cycles per second, formally known as "hertz".  The period is the inverse of frequency andl has the units of seconds per cycle, commonly stated simply as seconds.

Why does temperature increase when heat is lost?

Since kinetic energy is one of the forms of internal energy, the release of heat from an object causes a decrease in the average kinetic energy of its particles. This means that the particles move more sluggishly and the temperature of the object decreases.

D) crystalline solid that conducts current under certain conditions

Answers

Answer:

D) crystalline solid that conducts current under certain conditions

Explanation:

A semiconductor is any crystalline solid material whose electrical conductivity is intermediary between that of insulators and conductors. That is, a semiconductor does not conduct like a conductor but does more than an insulator.

Based on this, a semiconductor is said to only conduct electricity under certain conditions as opposed to conductors that do so under any condition. Example of semiconductors are silicon, carbon, antimony, arsenic etc.
