An object made from brass was left out in the sun for 17 hours had an initial temperature of 20 Degrees Celsius , later that day it's temperature was recorded to be 45 Degrees . The brass object had an initial length 18m . Calculate the change in objects length . Knowing that M a=19*10^ ^ -19

What are the three ways that an object can accelerate

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

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
