On a nice summer day, kim takes her niece madison for a walk in her stroller. if they start from rest and accelerate at a rate of 0.5m/s2,what is their velocity after they have traveled 5.0

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Which best represents the law of conservation of mass ?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
