In series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits.
And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
Option A and D
<u>Explanation:</u>
A circuit consists of number of passive and active devices in it. And depending upon the connections between the passive devices, the flow of current and potential drop across them will be specified.
Like if the passive devices are connected parallel to each other, the current flow through each device will vary but the voltage drop will be same. Similarly, if the passive devices are connected in series, then the current flow will be constant in the devices but the potential drop will vary.
Thus, in series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits. And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
Answer:
T = 273 + (-50) = 273 – 50 = 223 K
R = 188.82 J / kg K for CO2
Density (Martian Atmosphere) = P / RT = 900 / 188.92 x 223 = 900 / 42129.16 = 0.0213 kg / 
T = 273 +18 = 291 K, R = 287 J / kg k (for air) P = 101.6 k Pa = 101600 Pa
Density (Earth Atmosphere) = P / RT = 101600 / 287 x 291 = 1.216 kg /
Answer:
Light intensity refers to the strength or amount of light produced by a specific light source .
The force tending to lift the load (vertical force) is equal to <u>22.5N.</u>
Why?
Since the boy is pulling a load (150N) with a string inclined at an angle of 30° to the horizontal, the total force will have two components (horizontal and vertical component), but we need to consider the given information about the tension of the string which is equal to 105N.
We can calculate the vertical force using the following formula:
Hence, we can see that <u>the force tending to lift the load</u> off the ground (vertical force) is equal to <u>22.5N.</u>
Have a nice day!
