Why knowing the velocity of an airplane is more important to a traveller than knowing its speeda?
velocity is speed and direction. It would not be good to be traveling at a speed of 500 mph in the wrong direction!
What is the objects velocity after the 20 N force is applied for 5 seconds?
There is no answer to your question without knowing the direction of the velocity and of the force application.
How do you get area given pressure and velocity?
Velocity is not involved in the definition of pressure, so knowing it doesn't help you calculate pressure. Pressure = force/area You may be talking about wind pressure, which obviously does depend on the speed of the wind, or on the speed of the object through quiet air. In order to know the wind force, you have to know the specific size, shape, dimensions, and surface texture of the object past which the air is moving.
How do you calculate dish end weight?
Engineering requires calculation of the dish end diameter and circumference for proper fit before crimping. The weight can also be necessary in some applications. To determine the weight, knowing the substance and dimension, going to weight of unit of substance the calculation can be determined.
What is the relationship between acceleraion and velocity?
Acceleration increases the velocity. There are two physics formulas that you can use to see more how they interact. The first is a formula for determining your current velocity at a given moment t, knowing your initial velocity and your current acceleration. v = v0 + at (v0 is v-naught. The zero is usually written as a subscript.) You can solve this equation for a to get a formula for acceleration as well. a = (v-v0)/t So, basically, at any given interval t, the acceleration has been added onto the current velocity that many times.
Is their any general formula to calculate bearing OD?
No there is no proper formula for knowing the outer diameter
How do you calculate the radius of a turn based on a path or curve without knowing the circumference or diameter?
You cannot.
How do you calculate vessel height and diameter with knowing volume?
You wll also need to know its radius as well as its volume
Why is it so important to know the circumference of a circle when finding the surface area of a cylinder?
It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.It is not. Knowing its radius or diameter will do just as well.
How do you find the area of a circle by using its circumference y?
From the circumference y, you can find the diameter by dividing by pi. Knowing the diameter, you can calculate the area by either dividing the diameter by 2, squaring it and multiplying by pi, or by squaring the diameter, dividing by 4 and then multiplying by pi (they are mathematically equivalent). The end result is that you can calculate the area of a circle with circumference y from the formula: Area = π(y/2π)² = y²/4π
How do you calculate unit weight of steel?
weight of all steel can be calculated by multiplying unit volume with density.
Why knowing the velocity of an airplane is more important to a traveller than knowing its speeda?
velocity is speed and direction. It would not be good to be traveling at a speed of 500 mph in the wrong direction!
Velocity is distance time knowing this what are the SI units of velocity?
The velocity is distance per unit time and the SI unit is m/s.
How do you find the radius of a cone knowing only the diameter?
The radius is half the diameter, so just divide the diameter by 2.
How do you calculate the area of a sphere knowing just the diameter?
-- Take 1/2 of the diameter. That's the 'radius' of the sphere. -- 'Square' the radius. (Multiply it by itself.) -- Multiply the result by 4 pi. You now have the surface area of the sphere. P.S.: There really isn't anything else to know about a sphere other than its diameter.
How do you find out the the diameter of a circle if knowing the circumference?
Divide the circumference by the value of Pi - that will give you the diameter.
What is the minimum drain pipe diameter for two washing machines?
Residencial / commerical This is like asking How fast can a car go top speed with out knowing any facts about make /model The piping would be sized by the GPM discharge
