What is the Process that scientists use to solve a problem

Scientific method.

A state is named after this eastern woodland group

The eastern woodland group was known for hunting and gathering. The native people of the area were very traditional. The state of Delaware is named after an eastern woodland group.

How fiber-optic media converter works

Ethernet fiber Media Converter(fiber optical media converter) translates signals from a twisted-pair 10/100Base-Tx to 10/100Base-FX fiber optical cable.

Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h

60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy

A 1000 kg automobile is pulled by a horizontal tow line with a force of 800 N What is the automobile's acceleration

F = m a

a = F/m = (800) / (1,000) = 0.8 m/sec2

How much work is required to lift a 3.08 kg object from the bottom of a 10.3 m deep well

For an object moved along a vertical line near Earth's surface, the work required is given by:

Work = m g Δh

Where m is the object's mass (3.08 kg in this case), g is the acceleration due to gravity near Earth's surface (9.81 m/s2) and Δh is the change in the object's height (10.3 m in this case).

Can an object have no either potential energy and kinetic energy

Yes. If it is at whatever you define to be zero level for the purposes of calculating potential energy (often this will be ground level), and doesn't move, then it has zero (gravitational) potential energy, and zero kinetic energy.

Why did colonists turn to enslaved Africans for labor on their plantations

no

What is your weight in newtons if you weigh 53 kg

53kg equates to about 520 newtons (on Earth).

What two properties does the amount of potental energy depend upon

Weight and height. The potential energy of an object is its weight times its height. The potential energy is turned into kinetic energy as the object is dropped.

Potential energy is weight times height, kinetic energy is one half mass times velocity-squared.

Mgh = ½ M V^2

To reach a speed of 10 m/s this equation can be solved to show that the object must be dropped through a height of 5.1 metres.
