Answer:
(A) Their high energy
Explanation:
The higher the energy of the x-ray the more "likely" they will pass through.
The x-ray is electromagnetic energy caused by energy changes in an electron.
X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.
Answer:1.Air, 2.the ground,3.water
Explanation:I just got it right:)
The potential difference across a and b is 15 v. determine the electrical charge on the 3 μf capacitor will be 45 *
C
Capacitance, property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. Capacitance also implies an associated storage of electrical energy.
Charge (Q) stored in a capacitor is the product of its capacitance (C) and the voltage (V) applied to it. The capacitance of a capacitor should always be a constant, known value. So we can adjust voltage to increase or decrease the cap's charge. More voltage means more charge, less voltage... less charge.
charge = capacitance * voltage
Q = CV
= 3 *
* 15 v
= 45 *

Answer:
85 miles .
Explanation:
Displacement along the 110 South freeway = 260 - 150 = 110 miles
Displacement along the 110 North freeway = 150 - 175 = - 25 miles
Net displacement = 110 - 25 = 85 miles
So Joey's displacement from the 260 mile marker is 85 miles .
