It shows deflection for the presence of current.However it can't be used for the A.C. current used at home.hope this helped.
In electronics, the SI unit for current is Ampere. It is the amount of charge in Coulombs per unit time. It is named after the father of electrodynamics, Andre-Marie Ampere. Also, the current can be easily determined through the Ohm's Law, which states that current is equal to volts divided by the resistance. The answer is letter D.
Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The net force is 5 Newtons and the mass is 13 kilograms. Let's convert the units for force to make the problem and unit cancellation easier.
- 1 Newton (N) is equal to 1 kilogram meter per square second (1 kg*m/s²)
- The net force of 5 N is equal to 5 kg*m/s²
Now we know the values for 2 variables:
Substitute the values into the formula.
Since we are solving for the accleration we must isolate the variable, a. It is being multiplied by 13 kilograms and the inverse of multiplication is division. Divide both sides by 13 kg
The units of kilograms (kg) cancel.
The original measurements of force and mass ( 5 and 13) have 1 and 2 significant figures. We must round our answer to the least number of sig figs: 1.
For the number we found, that is the tenths place. The 8 in the hundredth place (0.384615385) tells us to round the 3 up to a 4.
The acceleration is approximately <u>0.4 meters per square second.</u>
Answer:
The frictional torque is
Explanation:
From the question we are told that
The mass attached to one end the string is
The mass attached to the other end of the string is
The radius of the disk is
At equilibrium the tension on the string due to the first mass is mathematically represented as
substituting values
At equilibrium the tension on the string due to the mass is mathematically represented as
The frictional torque that must be exerted is mathematically represented as
substituting values
To find the slope, use the equation: m = y2 - y1 / x2 - x1
