Answer:
V=IR
since the circuit is parallel both resistor have same voltage and different current value according to OHMs law.
total resistance in parallel=
1/R=1/R1+1/R2+...+1/Rn
since we have two resistor in parallel
Rt=R1R2/R1+R2
2*4/2+4=4/3 ohms
I=V/R
12/4/3=36/4=9Amp
OR
I=12/2=6amp
I=12/4=3amp
total current
I=6+3
9amp
Answer:
Because the output force is greater than the input force, the input distance must be greater than the output distance.
Explanation:
Answer:
68.8 Hz
137.6 Hz, 206.4 Hz
Explanation:
L = Length of tube = 2.5 m
v = Velocity of sound in air = 344 m/s
Distance between nodes is given by

Where n = 0, 1, 2, 3, ...
Making n+1 = n

where n = 1, 2, 3 .....
For fundamental frequency n = 1

Frequency is given by

The fundamental frequency is 68.8 Hz
First overtone

Second overtone

The overtones are 137.6 Hz, 206.4 Hz
Answer:
Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves.
Explanation:
Answer: No! Animal cells cannot be broken down further into living cells.
