How do you express 78,000 in scientific notation?

7.8 x 103

7.8 x 104

7.8 x 10-4

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
