What is joule's law of heating?
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
What are the factors that altered the periodic time for a pendulum?
The time period is directly proportional to the square root of length of the pendulum and inversely proportional to the square root of acceleration due to gravity.
Identify the two pieces of information you need to know the velocity of an object?
Displacement and Time, displacement is the distance with a direction ( vector quantity) , and time . Displacement and velocity are directly proportional, while velocity and time are inversely proportional..( The faster, the less time it will take) Velocity = Displacement ____________ Time
Is frequency proportional to distance?
Frequency is proportional to time, the number of cycles at a certain frequency is proportional to its length(distance).
How mass affect the time?
Mass doesn't effect time, energy effects mass (proportional) and velocity effects time (not proportional).
What is the equation or the formula getting power?
P(watt)=energy/time. Where power in measure in watt directly proportional to energy(work) and inversely proportional to time in seconds. 1W = .001kW
Are time and distance directly proportional to each other?
Time and distance traveled are directly proportional only if the velocity of the object in question is constant.
What does it mean when something is directly proportional?
Directly proportional means that both variables increase or decrease at the same time.
Is an increase in kinetic energy directly proportional to the time it takes for an object to fall slash distance it falls?
The kinetic energy of a falling object is directly proportional to the distance it falls.But the distance is not directly proportional to the time in fall, so the KE is not directly proportionalto the time either.
Formula of distance vs time?
Distance is directly proportional to time.(Which simply means that distance covered by object is directly proportional to time it took) Distance= Time*Speed * is the multiplication sign
Are reaction time and temperature directly proportional?
temperature is proportional to 1/time taken for reaction to complete (rate of reaction)
What is joule's law of heating?
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
What does v equals d divided by t mean?
Velocity = Distance / Time Velocity is defined as the change in Distance travelled over the Time taken to travel across it at this average rate of velocity. Therefore, average velocity and time are inversly proportional to one another, while distance is directly proportional to both time and velocity, and vice versa. At a fixed velocity, the travel time increases as the distance becomes longer; if the distance is fixed, then the velocity must become greater to make the time shorter.
Time constant of an RC circuit increases if the value of the resistance?
Increased The time constant of an "RC" circuit IS RC. So it's directly proportional to 'R' and also directly proportional to 'C'.
Give an example of direct proportion?
The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
How does distance and time affect the speed from object?
Distance and time do not, in general, affect the speed. Speed, however, can affect distance or time. Distance is directly proportional to speed, time is inversely proportional.
Is distance a function of time?
Definitely. Distance is directly proportional to time, and the proportionality constant is called "speed".
