When you listen to the radio watch TV or cook food in the microwave you're using a device that makes use of man-made electric magnetic waves which statement about electromagnetic waves is false

Why does a catalyst cause a reaction to proceed faster?

For a projectile launched at an angle, are the forces in the vertical direction balanced or unbalanced?

The two ropes seen in (Figure 1) are used to lower a 255 kg piano exactly 6 m from a second-story window to the ground.

Diffraction patterns are due to: interference refraction dispersion scattering

A car weighing 800 kg starts from rest due to the force of the engine, which evenly increases so that after the first second it has a value of 325 N. Calculate what speed it will havethe car after 10 s of movement and what path it took in that time.

What factors affect the speed of a wave? Check all that apply. the amplitude of the wave the energy of the wave the temperature of the medium the type of wave the type of medium

A sound level of 96 dB is how many times as intense as one of 90 dB?

Which type of waves are whale songs in an ocean?

Which is normally greater: static friction or sliding friction on the same object? Static friction is normally greater than dynamic friction. On the same object, static friction and dynamic friction are equal.

A child pulls a wagon 3.0 m using a force of 55 N at an angle 35° above horizontal. The force of friction on the wagon is 12 N. Calculate the net work done on the wagon
