When an object is pushed by a force and moves in the direction of the force, work is done on the object. The amount of work equals the force times the distance (W = Eg).
A small particle is pushed by a force of 2.6x10-4 newtons over a distance of 3.7x10-3 meters.
How much work was done on the particle?
Express the answer to the correct number of significant figures and in proper scientific
notation.
The force did 10 newton-meters of work on the particle.

What are the factors that affect the resistance of a wire?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
