Power. In physics, power is defined as the rate at which work is done. In other words, it measures how quickly energy is being transferred or transformed. Explore the concept of power in physics through an example of two weightlifters, one who lifts faster than the other, to see that power measures the rate at which work is done.

Which formula you use depends on whether or not the force is constant: 1. Work with Constant force. The first formula, work = force * Distance, is used where the force applied is constant. Solving these types of problems is relatively easy. All you have to do is multiply force by distance. Example
Jan 31, 2024 · Then, plug the radius into the formula for finding area, area = πr^2. Ten squared is 100, and 100 times π is 314.16. Therefore, the area of the circle is 314.16 inches squared. To find the area using the circumference, or the distance around the circle, use the formula area = c^2/4π, where c is the circumference.

The formula you need to use is \text {Volume}=\cfrac {4} {3} \, \pi r^3. Volume = 34 πr3. Substitute the values into the formula. Show step. You need to substitute the value of the radius of the sphere into the formula. You need to divide the diameter by 2 2 to calculate the radius r. r. r=9\div 2=4.5 r = 9 ÷ 2 = 4.5.
Apr 13, 2024 · So treat squares like rectangles in terms of finding its area. 2. Learn the equation for finding the area of a rectangle. The equation for finding the area of a rectangle is simply A = L * W. [3] This means that the area is equal to the length of the rectangle times its width. Method 2.
