Answer:
The correct option is D
Explanation:
In trying to achieve what the student wanted to see, which is to see the relationship between the weight the cord can hold and how long the cord will stretch. Since the origin of the graph is from zero, the value plotted on the vertical axis would be just the length caused by each weights. Thus, <u>the original length would have to be subtracted from the measured length to determine the actual length caused by the weight added to the cord</u>.
Answer:
circuito paralelo
Explanation:
Siempre el circuito en paralelo dara una resistencia menor. Recuerda que las resistencias se suman en el circuito en serie, an cambio en el circuito en paralelo, la corriente se bifurca de manera de circular con mayor intensidad por las ramas que tengan menos resistencia, y tal situacion llevara siempre a producir una menor resistencia equivalente.
Thinking critically is basically thinking outside of the box, so it's asking how does the bulub filament change after it's on, a filament is basically the wiring inside.
D. It’s a composite because it’s a mixture of cement, sand, and other granular pieces.
Answer:
current in series is 1.33 mA
current in parallel is 5.48 mA
Explanation:
given data
voltage = 8 V
resistors R1 = 2.5 kilo ohms
resistors R2 = 3.5 kilo ohms
to given data
current flow
solution
current flow in series is express as
current = voltage / resistor
put here all value
current = 8 / (2.5 + 3.5)
current = 8 / 6
current = 1.33 mA
and
current flow in parallel is express as
current = voltage / resistor
put here all value
current = 8 / (1/ (1/2.5 + 1/3.5))
current = 8 / 1.45
current = 5.48 mA
