Which of the following measurements is equal to 150 dL?
MrRissso [65]
This is a case of metric system of measurements. The scale of the metric system only differs by a factor of 10. The scale (from greatest to least) is kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter and milliliter. If the unit is 150 dL, and you want to find the equivalent dkL measurement, just move the decimal point 2 decimals places to the left (just follow the scale). The same procedure is done for the other metric units.

150 dL = 1.5 dkL
150 dL = 15 L
150 dL = 1,500 cL
150 dL = 15,000 mL

From the choices, the answer is letter C.

A small toy car draws a 0.50-mA current from a 3.0-V NiCd (nickel-cadmium) battery. In 10 min of operation, (a) how much charge
adelina 88 [10]

Answer:

0.3 Coulomb charge flows through the toy car.

0.9 Joules of energy is lost by the battery

Explanation:

Current(I)=\frac{charge(Q)}{Time (T)}

a)

Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)

milli Ampere = 0.001 Ampere

Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s

1 min = 60 seconds

Charge flows through the toy car be Q

0.50\times 0.001 A=\frac{Q}{600 s}

Q=0.50 \times 0.001 A\times 600 s=0.3 C

0.3 Coulomb charge flows through the toy car.

b)

Heat(H)=Voltage(V)\times Current(I)\times Time(T)

Voltage of the battery = V = 3.0 V

Current drawn from the battery = 0.50 mA = (0.50 × 0.001 A)

Duration of time current drawn = T = 10 min = 10 × 60 s = 600 s

H=V\times I\time T=3.0 V\times 0.50 \times 0.001 A\times 600 s

H = 0.9 Joules

0.9 Joules of energy is lost by the battery

What does radioactive mean?
stepladder [879]

Answer:

B. Emitting radiation as a result of unstable nuclei.

Explanation:

Radioactive by definition is "Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction". So we would assume that the answer would be B.
