Ann and Jesse’s mom is driving them to school. They are listening to music on an FM radio station. When they ride in the car with their father, they sometimes listen to AM radio. Ann wants to find out the difference between AM and FM radio signals. She finds a diagram in an online search. How do the AM and FM radio waves compare? In your answer, explain how the wavelength affects the frequency of the radio waves.

What is the relationship between globular clusters and the milky way?

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i. e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
