The sound gets louder, like hitting a metal pole on a thin metal beam, the energy increases as the sound does.
100 g lead target. Lead has a very high density which means even a very small volume and weight quite a lot. So because the lead target weighs only 100 g it's going to be small in size compared to other targets which are all made of lesser dense materials than lead.
Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example
answer : a) 14 ohms b) 0.86 amps c) 10.32 V
Explanation:
Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms
Voltage source = 12V
<u>Assuming that the Resistors are in series </u>
<u>a) Determine Total resistance </u>
Req = R1 + R2 + R3
= 3 + 4 + 5 = 14 ohms
<u>b) Total current </u>
Ieq = V / Req
= 12 / 14 = 0.86 amps
<u>c) The Total Voltage over the entire system </u>
Vt = ∑ Voltage drops
= ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )
= 10.32 V
B. Inertia and gravity must be balanced.
Sir Isaac Newton, held the theory that light was made up of tiny particles<span>. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of </span>waves<span>vibrating up and down </span>perpendicular<span> to the direction of the light travels, and therefore formulated a way of visualising wave propagation.</span>
