Answer:
The total resistance is 106 Ω and the current in the circuit is 0.11 A.
Explanation:
Given that,
Voltage of the battery, V = 12 V
Resistors 34 Ω, 42Ω, and 30Ω are connected in series.
The total resistance is given by :}
R = 34 + 42 +30
= 106Ω
Let I is the total current in the circuit. Using ohm's law to find it such that,
Hence, the total resistance is 106 Ω and the current in the circuit is 0.11 A.
A= 50/8 m/s^2
<span>vf=at=50/8 * 5= 250/8 m/s at t=5sec </span>
<span>time to get to 50m/s </span>
<span>50=50/8*t or t=8 seconds </span>
<span>distance=1/2 a t^2=1/2 50/8 64 </span>
<span>distance= 400 m check that.</span>
Answer:
If the earth stops rotating the apparent weight will increase at most of the places because the upward component of the centrifugal force due to rotation will disappear.
Answer:
The experiment to determine the coefficient of static friction between a rough block and an incline plane is detailed in the explanation.
Explanation:
A simple experiment is as follows:
Take a weight in which its mass is known and hold it with a roller at the end of the inclined plane with a rope.
Place the weight on the plane inclined horizontally with the ground, forming a zero degree angle.
Gradually lift the weight so that the angle of incline begins to increase.
Observe that the weight will begin to slide. This angle will be the angle theta.
In this way, the coefficient of friction will be calculated as the tangent of the angle theta.
Take a different weight and repeat the procedure to get different values of the coefficient of friction.
By averaging the coefficients of friction, a final value will be obtained.
