What is one half accleration times time squared?

This is the physics formula for displacement, more commonly called distance. But, it assumes you start at zero speed. The time units cancel out in the formula, so the answer comes out in terms of distance.


How do you find the velocity of a mass at half the amplitude?

To find the velocity of a mass at half the amplitude of its oscillation, you can use the formula for the velocity in simple harmonic motion: v = ω√(A^2 - x^2), where ω is the angular frequency, A is the amplitude of the oscillation, and x is the displacement from equilibrium. At half the amplitude, x = A/2, so plug this into the formula to calculate the velocity.


What is the half power frequency formula and how is it used in the field of electronics?

The half power frequency formula is used to calculate the frequency at which a signal's power is reduced by half. In electronics, this formula is important for determining the bandwidth of a circuit or system, which is crucial for designing filters, amplifiers, and other electronic devices. The formula is given by f 1 / (2RC), where f is the half power frequency, R is the resistance, and C is the capacitance in the circuit.


What is the half distance formula and how is it used in mathematics?

The half distance formula is a mathematical formula used to find the midpoint between two points on a coordinate plane. It is calculated by averaging the x-coordinates and y-coordinates of the two points separately. This formula is commonly used in geometry and algebra to determine the center point between two given points.


If the period of simple pendulum is halved its time period will become. What?

If the period of a simple pendulum is halved, its time period will become half of the original period. This means that it will complete one full swing in half the time it originally took.

How can one determine the cell potential in a chemical reaction?

The cell potential in a chemical reaction can be determined by calculating the difference in standard electrode potentials of the two half-reactions involved in the cell. The cell potential is the difference between the reduction potentials of the two half-reactions. The formula for calculating cell potential is Ecell Ered(cathode) - Ered(anode).


How do you figure the gallons of fuel in a horizontal cylinder tank?

The actual gallons of fuel would depend on how full the cylinder tank is. Here is the formula for calculating the maximum capacity of the tank.The formula for calculating the volume of a cylinder is V = πr2hV = volumeπ = PI (approximately 3.14)r = radius (half the diameter of the round portion of the tank)h = height (or length) of the tank


When you multiply half the mass of an object by its speed squared you calculate its?

You are calculating the kinetic energy of the object using the formula KE = 0.5 * m * v^2, where m is the mass and v is the speed of the object. This formula gives you the energy associated with the object's motion.

Do all triangles have the same formula of base multiplied by height divided by 2?

Yes - for calculating the area of any triangle - you either halve the base and multiply by the height - or - as you said half the height times the base. either way will work.
