If a sinusoidal electromagnetic wave with intensity 18 w/m2 has an electric field of amplitude e, then a 36 w/m2 wave of the same wavelength will have an electric field of amplitude if a sinusoidal electromagnetic wave with intensity 18 has an electric field of amplitude , then a 36 wave of the same wavelength will have an electric field of amplitude (a) 4e (b) 22√e(c) 2e(d) 2√e.

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Which sections of the heating curve illustrate this process?
