I think it will be 800j because right absorb mean getting more
Answer:
the time at which it passes through the equilibrum position is:
t = 0.1 second
Explanation:
given
w= 4pounds
k(spring constant) = 2lb/ft
g(gravitational constant) = 10m/s² = 32ft/s²
β(initial point above equilibrum) = 1
velocity = 14ft/s
attached is an image showing the calculations, because some of the parameters aren't convenient to type.
Answer:
640 J
Explanation:
ΔKE = KE − KE₀
ΔKE = ½ mv² − ½ mv₀²
ΔKE = ½ m (v² − v₀²)
ΔKE = ½ (80 kg) ((5 m/s)² − (3 m/s)²)
ΔKE = 640 J
Her kinetic energy increases by 640 J, so she does 640 J of work.
Answer:
Power of the electron beam in the x-ray tube is 2304 W
Explanation:
Given;
voltage of the electron beam in the x-ray tube, V = 144 kV = 144 x 10³ V
current of the electron beam in the x-ray tube, I = 16.0 mA = 16 x 10⁻³ A
Power is given as the product of voltage and current in a circuit.
Power of the electron beam in the x-ray tube, P = V x I
Power of the electron beam in the x-ray tube, P = 144 x 10³ V x 16 x 10⁻³ A
P = 2304 W
Therefore, power of the electron beam in the x-ray tube is 2304 W
<span>I don't think there is enough information from the question. If you are asked to calculate the number of microbes in a certain area., then it should be that the total area or maybe the volume of that should be given so you can estimate the number of microbes. Hope this helps.</span>
