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
Answer:
When net force of zero acting on a ball which is at rest , then the object center of mass will not accelerate , but the object may begin to rotate .
Explanation:
Here when there is an object where several forces are acing upon are zero then the center of mass will not accelerate because we know that
Where acceleration of center of mass
= net force = 0
So the acceleration of center of mass will be zero
But the torque ,may not be zero as torque is product of individual force and perpendicular force .
Since if torque is not equal to zero then the object may begin to rotate
Answer:
Positive psychology is important because discovering what leads people to live more meaningful lives can translate to better strategies for managing mental illness, correcting negative behaviors, and increasing our happiness and productivity.
Explanation:
Answer:
The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected. ... These sounds will interfere to produce detectable beats.
