how to get a rheostats to create heat? project?

i want to heat a piece of metal up ( copper ) with a rhetostat. this is all home made with a small extension cord,120 v light dimmer. im using a thin metal to try and heat it up. is 120 v enough to heat it up or not enough? i figure no but cannot find out. and im using lots of safety percautions doing this .
i meant i know 120 v is enough but unsure. but i am not sure what you mean by issue is heat current. the powers there but there isnt enough current to get it there? well how can i a improve this? more metal? thicker wires? thinner wires?

This is a very dangerous experiment to heat up copper wire with 120V. And no body uses copper wire as heater. The dimmer blows right away because of overload.
You need Nickle chromium heater wire and the total resistance at least 30 ohm. Dimmer cannot handle more than 600 watts power.

Calculate gun fired the ball as from space station?

This question is to determine the mathematical method for calculation: azimuth, elevation, and cooking time of a hypothetical shooting a bullet (2500 fps muzzle velocity – 180 grain copper bullet jacket) orbiting the sun from one station space theory (estimated fixed height of 100 miles – stationary orbit over Cape Hatteras, North Carolina). Please take into account not efects of radiation and heat of the sun and is that the planet such as composition, may be that Mars was adopted. For this question, we want to have test bullet projectile hit the surface to see the sun, Mathematics involved. Please use, miles per hour, etc., and non-metric units. I ask this question for the answer to question someone else and I realized that I do not have the knowledge necessary to perform the necessary calculations. In addition, the enormous attraction that given the attraction of the sun (as compared to the Earth) change the velocity of the projectile during flight ..

The velocity of 2,500 fps is much, much too slow to get to the sun never set. To achieve the sun, you must first escape Earth's gravity, which requires about 36,000 fps. Then you have to cancel most of the orbital velocity of the earth, approximately 97,000 fps is to avoid missing the centrifugal force of the ball to the sun. So you need a top speed of about 133 000 frames per second to take the sun. You will need the fire against the orbital motion of the earth, the 90 degree from the direction of the sun.
