Answer:
Explanation:
In our previous articles, we observed the theoretical formulas of Ohm’s law, its calculations in the lab report, and experiment. Today you’ll learn the verification of theory vs experimental results on a 1 kΩ resistor.
The theoretical results are obtained from the formula of Ohm’s law: V = IR. The experimental verification is provided for a metal film 1 kΩ (±0.05%). We have used a high-quality resistor with negligible tolerance value so as to reduce the tolerance error.
The little problem in our calculations arises due to improper handling of multimeter probes. You can learn the complete method to perform the Ohm’s experiment here and can calculate the current values by using the Ohm’s law calculator.
Answer:mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle in the absence of friction
Explanation:
The mechanical advantage of a wheel and axle is equal to the ratio of the radius of the wheel to the radius of the axle in the absence of friction
Answer:
1.47×10¯⁸ N
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 1.5×10¯⁹ Kg
Acceleration due to gravity (g) = 9.8 m/s²
Force (F) =?
The force of the snowflake can be obtained by using the following formula:
F = mg
Where:
F => is the force
m => is the mass
g => is the acceleration due to gravity
F = mg
F = 1.5×10¯⁹ × 9.8
F = 1.47×10¯⁸ N
Thus the force of the snowflake is 1.47×10¯⁸ N
Answer:
<h2>
30 miles/hour, and 2.24 miles/hour</h2>
Explanation:
What is average speed?
It is the total distance traveled divided by the time taken to cover the total distance traveled
Given that the various distances are
20 miles and 10 miles
the total distance traveled is 20+10= 30 miles
the average speed is expressed as
average speed= total distance/time taken
average speed= 30/1
average speed= 30 miles/hour
The average velocity is a vector quantity
the velocity is the average displacement divided by time taken
average velocity= displacement / time
average velocity= 2.24 /1
average velocity= 2.24 miles/hour
