Is the time required to swing to and fro on a playground swing longer or shorter when you stand rather than sit?
you can compare the swing motion to the motion of simple pendulum
well in a simple pendulum the time for to nd fro motion is called time period is propotional to the sq. root of length.
T=2(pi) sq.root(l/g)
l is length of pendulum
g is acc. due to gravity at dat point
now ,the length is important here
length is the dis. of the point of suspention to the centre of mass of the body hanging,so if u stand the centre of mass moves up rather than sitting .
which means more time period wen we sit than stand
What else can I help you with?
Why is the longer leg longer than the shorter leg if the shorter leg is longer than the longer leg?
Because if the shorter leg was shorter than the longer leg was long, then the longer leg wouldn't be longer than the shorter leg is short. The short leg would be the longer one rather than the long one being the short one.
If a cannonball is shot from a longer barrel cannon rather than a shorter barrel cannon it willl have a?
Longer (effective) range. Longer barrels on a firearm allow for more complete burning of the propellant, which results in a higher muzzle velocity, which in turn results in a longer effective range, when compared to an identical weapon with a shorter barrel.
Why is it easier to move an object up a long ramp rather than a short one?
It is easier to move an object up a long ramp because the longer ramp allows for a shallower incline, which reduces the force required to lift the object vertically. This decreases the amount of work needed to overcome gravity compared to a shorter, steeper ramp.
Is the pencil had been lost in the playground an active or passive voice?
The phrase "the pencil had been lost in the playground" is in passive voice. In this construction, the subject (the pencil) receives the action (being lost) rather than performing it. Active voice would involve the subject performing the action, such as "Someone lost the pencil in the playground."
Does heat have shorter or longer wavelength than light?
Heat does not have a specific wavelength because it is a form of energy transfer rather than a specific type of electromagnetic radiation like light. Heat is typically associated with infrared radiation, which has longer wavelengths than visible light.
How is the screw machine products industry changing?
Many manufacturers are turning to computer-controlled rather than cam-controlled operations, because of the longer set-up time required for cam-driven machines and the level of expertise required to operate them.
What led the Panama canal?
The building of the Panama Canal was to create a shorter passage for shipping between the Atlantic and Pacific Oceans, rather than the longer, more hazardous route round Cape Horn, the southern tip of South America.
What are the best types of wood for building a bookcase?
It depends on the length of shelf you desire. For a longer length of shelf a hardwood like maple would be best. For a shorter length shelf balsa is more than satisfactory and rather cheap.
What's the required age to be on Zwinky?
The Required age to be on Zwinky is rather be 14 and up
If you were given an empty piece of land would you rather using it to build a garden or a playground for children?
I would choose to build a playground for children. A playground provides a space for physical activity, social interaction, and imaginative play, all of which are crucial for a child's development. While a garden can be beautiful and calming, a playground offers a more dynamic environment that encourages community engagement and fosters a sense of joy among children. Ultimately, investing in children's play contributes to their overall well-being and happiness.
How many meters are in a playground?
The term "playground" typically refers to a recreational area with various equipment and structures for children, rather than a specific measurement. Therefore, the size of a playground can vary significantly based on its design and location. Playgrounds can range from small community parks measuring a few hundred square meters to larger, more extensive play areas that cover several thousand square meters. To determine the exact number of meters in a specific playground, one would need to measure its dimensions.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
