<h2>Answer:</h2>
<u>The correct answer is</u><u> the current will decrease by a factor proportional to the number of resistors. </u>
<h2>Explanation:</h2>
In a parallel circuit, when all the resistors are in parallel to the power supply, the voltage across all the branches in parallel is the same but the current decreases as we add more load. If each current path P has different resistances, highest current flows through the path which has the least resistance and hence current decreases proportionally.
Answer:
The length of the wire is 2.86 m
Explanation:
Given:
Current A
Magnetic field T
Force N
Angle between wire and magnetic field 46°
The magnetic force on the current carrying wire is given by,
Where length of wire
m
Therefore, the length of the wire is 2.86 m
The battery will be full still a 8v bc of no time comparison
Answer:
In kinematics questions we need to separate the question into different parts if the acceleration changes. Here, there are three time intervals where acceleration is different.
1) a(t) = 96t. We can find the velocity function of the rocket by integrating the acceleration function. Then we can integrate again to find the position function.
'C' is the integration constant. We can find this constant by investigating the initial conditions.
We know that the rocket is initially at rest, so 'C' should be zero.
Again, the rocket started from ground zero, so C = 0.
We should conclude the first part by calculating the final position and final velocity of the rocket.
2) For the second part, the rocket is in free fall, so
The maximum height that the rocket reaches is when its velocity is zero.
So,
The maximum height is
The final positions for the part 2 is
3) With the parachute, the velocity is dropped from -276.4 to 16 in 5 s.
The rocket lands
