A wave pulse travels along a horizontal string. As the pulse passes a pint on the string, the point moves vertically up and then back down again. How does the vertical speed of the point compare to the speed of the wave?

• the speed of the point equals the speed multiplied by the wavelength and divided by the string's length.
• the wave speed equals the point speed multiplies by the wavelength and divided by the string's length.
• the speed of the point is 2 times greater than the wave speed.
• the speed of the point could be neglected compared to the wave speed.
• the wave speed could be neglected compared to the speed of the point.
• the speeds could not be uniquely compared, because there is no fixed relationship between them.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
