It has been shown that large and small masses fall at the same rate. This has been repeatedly tested, including on Earth, in space, and on the moon. Which tenet of science does this demonstrate? (1 point) The natural world can be described using natural phenomena.
Scientific theories are based on multiple lines of evidence.
O Scientific discoveries are falsifiable.
The same physical rules apply throughout the universe,

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? a)\vec ein the +xdirection,\vec bin the +ydirection. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction b)\vec ein the -y direction,\vec bin the +x choose+ x direction- x direction+ y direction- y direction+ z direction- z direction c)\vec ein the +z direction,\vec bin the -x direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction d)\vec ein the +y direction,\vec bin the -z direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction

How does changing the frequency affect the energy of the wave?
