I believe the correct answer from the choices listed above is option D. The amplitude, period, and frequency of the motion of the mass are given by <span>amplitude = 3, period = , and frequency = 2. The standard form of this model would be as follows:
y = A sin Bx
where A is the amplitude and 2pi/B is the period. Frequency is the reciprocal of the period. Hope this answers the question. Have a nice day.</span>
One of the handy formulas for electrical power is
Power = (Voltage)² / (Resistance)
Since the voltage is squared, if you double the voltage and
the resistance doesn't change, the power will increase by
the factor of (2²), which is 4 times the original power.
Pretty sure It’s false. Hope this helps and good luck :)
Answer:
With the given information, we can assume that the start and the end of the trip are the same place. (Suppose, a tour where the bus starts at the school, then it goes to a given location, and then it returns to the school)
Now, the definition of displacement is:
The difference between the final position and the initial position.
But if the start and the end of the trip are the same place, then the initial and final position must be the same. Then the difference between the final position and the initial position is zero.
This means that the displacement of the school bus from the start to the end of its trip must be zero.
Answer:
<em>The tension in the web is 0.017738 N</em>
Explanation:
<u>Net Force</u>
The net force exerted on an object is the sum of the vectors of each individual force applied to an object.
If the net force equals 0, then the object is at rest or moving at a constant speed.
The spider described in the question is hanging at rest. It means the sum of the forces it's receiving is 0.
A hanging object has only two forces: The tension of the supporting string (in our case, the web) and its weight. If the object is in equilibrium, the tension is numerically equal to the weight:
T=W=m.g
The mass of the spider is m=1.81 gr = 0.00181 Kg, thus the tension is:
The tension in the web is 0.017738 N
