What happens to a moving object with zero nets force acting on it?
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
How does terminal velocity affect acceleration?
The terminal velocity of an object moving through a fluid under the force of gravity (let's assume the fluid is air for sake of discussion) occurs at the speed where the drag force of the air on the object becomes equal to the weight of the object. At this point the object has stopped accelerating and is in uniform motion (constant speed).For example, a skydiver jumping out of a plane will accelerate towards the Earth. At first the skydiver is accelerating at 9.8 m/s2, the gravitational acceleration of the Earth. But as he accelerates to higher speed, drag force becomes greater and the rate of acceleration slows. Drag force is proportional to the square of the speed, by the way. Eventually the skydiver will reach a speed (around 120 mph depending on the orientation of the skydiver's body) where the drag force is equal to his weight. That will be his terminal velocity.
What is the energy transformation in bell?
The chemical energy of the battery is transformed into electrical energy to light the lamp. When an external circuit is completed around the battery, chemical reactions occur inside the cell or cells, and electric current flows to do the work of heating the filament in the lamp to incandescence. We've got light. cemical-light-thermal.

How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
Around a positive charge we have a repulsive field and around negative charge we have an attractive field.

A transformation in which a figure turns around a point?
rotation (i think)
What is the skydiver acceleration?
Upon leaving the aircraft, a skydiver rapidly reaches something called terminal velocity. This is where the resistance of the air matches the mass of the skydiver. At this speed, the skydiver maintains a relatively constant speed. Typically this is around 120mph in a flat body position and takes approximately 10 seconds to reach. For more questions about skydiving, see the attached link.

Its called points maybe
How many seconds does a skydiver open hes chute?
That depends on what orientation the skydiver is in. The most stable position is belly to earth or flat and this typically has a speed of around 120mph. Another position is headup (seated arm-chair) or headdown position and this increases the speed to around 150mph. At the end of the spectrum is the speed skydiver who can reach speeds over 300mph by streamlining their body and wearing slick shiny clothing. Equally at the slowest end is the wingsuit skydiver who achieves lift by a series of fabric wings between the arms and legs. They can slow their decent down to 30 or 40 mph, but this is counteracted by a high forwards speed.
When was Alice Cullen created?
Her Transformation date isn't really known but she was born around 1901.
What forces act on a skydiver as they are diving?
when a skydiver jumps out of a plane, the dominant force is gravity, pulling him/her towards the ground, although some air resistance is also acting on him/her, allowing him/her to fall at a steady speed (not dropping like a stone), so the forces acting on the skydiver are almost balanced. of course, all that changes when the parachute opens. then the air resistance greatly increases, drastically slowing the descent down to earth.

What are the lowest and highest terminal velocity while skydiving?
In a belly to earth body position, the average terminal velocity of a skydiver is around 120mph. This takes approximately 10 seconds to reach this speed. The most common discipline in the sport is formation skydiving and that takes place in this orientation.However, the terminal velocity of a skydiver can have variables which can greatly affect this speed:The clothing / jumpsuits they wear. Skin-tight nylon is more aerodynamic than rough cordura material. Heavier jumpers tend to wear cordura in their jumpsuits.The size and weight of the skydiver. A tall thin person will need to near skin-tight clothing to increase their speed. Otherwise they may fall around 10mph slower. Visa verca a small heavy person may need a baggy cordura jumpsuit to help them reduce their fall rate.The orientation of the skydiver. In addition to the belly-to-earth body position, there is also a headup/headdown body position which is used for the discipline of freefly. This is around 150 to 160mph. In fact, in the discipline of speed skydiving, the jumper has no official terminal velocity as they accelerate for the duration of the freefall, often reaching speeds in excess of 300mph.
What transformation gives the same result as a rotation of 180 around the origin followed by a reflection over the x axis?
Reflection in the y-axis.
What does dilated mean in math?
it means a transformation in which a polygon is enlarged or reduced by a given factor around a given center point.so its an enlargmant or a reduction
What is translation reflection and rotation?
translation: is a slide reflection : is a flip roation: you rotate the triganle around like 180 degrees
