What is the difference between planets period of rotation and period of revolution?
The difference between the rotation and revoulution is that rotation is the spiinning of the planet on its axis and revoulution is the orbiting of the planet around the sun.
How will be the value of g vary ar different distances from the hub of a rotating space station?
The value of gravitational acceleration, g, will decrease as you move farther away from the hub of a rotating space station due to the centrifugal force generated by the rotation. At rotation speeds where the centrifugal force and gravitational force balance, you will experience a simulated gravity equal to g, but this balance point will vary depending on the rotation speed and distance from the hub.
What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation of a molecular cloud tends to increase as it collapses to form a star due to the conservation of angular momentum. This rotation can lead to the formation of a protostellar disk around the young star, influencing the subsequent evolution of the star and potentially contributing to the formation of planetary systems.
Motion around a central axis is called?
It is rotation.
What is the difference between Earths revolution and Earths rotation?
The term rotation refers to the Earth turning on its axis once per day. The term revolution refers to the earth circling the sun once per year.
When the radius is increased does the period of rotation increased or decreased?
When the radius is increased, the period of rotation will increase. This is because a larger radius means the object has to travel a greater distance in the same amount of time, leading to a longer period of rotation.
In uniform circular motion when the radius is increased does the period of rotation increase or decrease?
When the radius of the circular motion is increased, the period of rotation also increases. This is because the period of rotation is directly proportional to the radius of the circle in uniform circular motion.
What does an ice skater do to change her rotational speed?
She can move her arms inwards - to increase the rotation speed - or outwards - to decrease it.
What is gained by increasing the rotation speed of a disk or CD?
increase tranfer rate and decrease average access time
If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
What change would occur if the earths rotation significantly decreased?
The length of a day would increase and the number days in a year would decrease.
How can I adjust the rotation of a sprinkler head?
To adjust the rotation of a sprinkler head, locate the adjustment screw on the top of the sprinkler head. Use a screwdriver to turn the screw clockwise to decrease the rotation or counterclockwise to increase it. Test the rotation by turning on the sprinkler system and observing the coverage area. Adjust as needed until the desired rotation is achieved.
What would be the probable effect on the earth's equatorial diameter the speed of rotation increased?
If the speed of rotation of the Earth were to increase, the centrifugal force acting on the equator would also increase. This would cause the Earth to bulge slightly at the equator, leading to a small increase in the equatorial diameter.
Why moment of inertia is also called rotational inertia?
Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
What movement does not increase or decrease the angle between bones?
Isometric contraction is a type of muscle movement that does not result in any change in the angle between bones. This type of contraction involves the muscle producing force without changing its length or causing movement at a joint.
Do you breaks increase friction or decrease friction?
Brakes increase friction in order to slow down or stop a vehicle. When the brake pads clamp down on the brake rotors, the friction between them generates heat and slows down the rotation of the wheels.
What can be done to increase the speed of rotation of the coil?
To increase the speed of rotation of the coil, you can increase the voltage applied to the coil or reduce the resistance in the circuit. Additionally, using a stronger magnetic field or reducing the friction in the system can also help increase the speed of rotation.
