Answer:
0.7945 Hz
Explanation:
Data provided in the question:
Length of the arm = 0.59 m
Since the center of mass lies at about of its length
Thus,
Length of the simple pendulum = × 0.59 m = 0.3933 m
Now,
Frequency of vibration, f =
Thus,
we have,
Frequency of vibration for the arm =
or
Frequency of vibration for the arm = 0.7945 Hz
Answer:
81.3ohms
Explanation:
Resistance is known to provide opposition to the flow of electric current in an electric circuit.
Power dissipated by the computer is expressed as;
Power = current (I) × Voltage(V)
P = IV... (1)
Note that from ohms law, V = IR
I = V/R ... (2)
Substituting equation 2 into 1, we will have;
P = (V/R)×V
P = V²/R.. (3)
Given source voltage = 100V, Power dissipated = 123W
To get resistance R of the computer, we will substitute the given value into equation 3 to have
123 = 100²/R
R = 100²/123
R = 10,000/123
R = 81.3ohms
The resistance of the computer is 81.3ohms
PART A)
Here by force balance along Y direction
Force balance along X direction
now by torque balance
PART B)
now from above equations
now net reaction force of wall is given as
Let's think about the meaning of k, the spring's constant. Hooks law states:
or, rewriting it:
where F is the force applied by the spring when we compress/release it of a certain amount of displacement x.
As we can see from the formula, the higher the value of k, the stronger is the force of the spring when we compress it of a certain fixed value x, so it will be more difficult to compress it with respect to a spring with smaller k. This means that the higher k, the stiffer is the spring.
