How many times will the wheel of a car rotate in a journey of 88 km given that the diameter of of wheel is 56 cm?
Well, isn't that a lovely question! To find out how many times the wheel will rotate, we first need to calculate the circumference of the wheel using the formula 2 x π x radius. Then we can divide the total distance of 88 km by the circumference of the wheel to find our answer. Just remember to breathe, take your time, and enjoy the journey of learning something new today.
How do you rotate an angle in maths?
You don't rotate the angle, you rotate an object by that angle, for example if you had to rotate something 180o it would flip over.
How many times will a 5 cm pulley turn when attached to a 10 cm pulley?
In relation to the 10 cm pulley a 5 cm pulley has half the circumference thus will rotate on the same line or belt twice as often. circumference = 2 x pi x radius or pi x diameter, when comparing 2 circumferences the value of pi is immaterial. Thus 10cm/5cm = 2
How many revolutions are made by a wheel 40cm in diameter in travelling 352m?
Diameter = 40 cm implies circumference = 40*pi = 125.7 cm So, in travelling 352 metres = 35200 cm, the wheel will rotate 35200/125.7 = 280.1 times (approx).
How many times would a football rotate if rolled around the middle circumference of another football of the same size?
If I understand the question, it would be once. I understand the situation to mean that if you had two footballs of the same size and rolled one around the middle of the other, how many times would you see the laces straight up basically (how many rotations)? Since the radii are the same it would just go through one rotation, covering its circumference in distance and since this is the circumference of the other ball it would be finished rotating. It's hard to show without a picture.
When riding a bike what do the bicycle wheels do around their axles?
Rotate
Does it matter how big the wheel is when measuring RPMs?
No. A revolution is a revolution is a revolution. Two wheels of different diameters can have the same rotational velocity (in rpm) or angular velocity (in radians per second or degrees per second). Mark the outer edge of the wheel, and count the number of full revolutions it makes in one second. But I have a feeling your question is poorly worded. You should realize that a smaller wheel will rotate faster than a larger one for a given linear velocity. For example, if you are riding a bicycle, say, with a small wheel on the front and a large one on the back, the smaller front wheel will need to rotate faster -- that is, it's angular velocity will be greater -- than the larger back wheel.
What is is the suns revolution period of the sun?
The Sun doesnt Rotate
What is the rotational analog of force in linear motion?
Torque is the rotational analog of force in linear motion. It represents the force that causes an object to rotate around an axis. Just as force is required to accelerate an object in a straight line, torque is required to rotate an object.
What are the two primary motions of earth?
rotate and revolve
What is the purpose of an axle cone in a bicycle wheel?
The purpose of an axle cone in a bicycle wheel is to provide a smooth surface for the bearings to rotate on, allowing the wheel to spin freely and smoothly.
Why does a bicycle speed up when you start pedalling?
Because when you push down on the pedals the rear wheel is forced to rotate.
What is the function of a bicycle axle in the overall structure and performance of a bicycle?
The bicycle axle serves as the central shaft that connects the wheels to the frame of the bicycle. It provides support and stability for the wheels, allowing them to rotate smoothly and efficiently. The axle also helps distribute the weight of the rider and any cargo, contributing to the overall performance and handling of the bicycle.
Solar system words that start with R?
rotate, revolve, revolution, redonkulous.
How can you make something move up and down or rotate with a motor?
To make something move up and down with a motor, you can use a linear actuator that converts rotary motion into linear motion. To make something rotate using a motor, you can attach the motor to a shaft or gear mechanism that will rotate the object. By controlling the speed and direction of the motor, you can achieve the desired movement.
Can a bicycle paddle be used as a turbine to generate small amount of electricity?
Yes, it can. But you will need a great amount of force to rotate it.
What does it mean by the rotation and revolution of a planet?
It means to revolve around the sun and rotate on its axis
