How can citizens affect environmental policy at the local, state, and national levels

A force of 50 n is exerted to the right on a 15 kg car at the same time a 30 n force is exerted to the left on the car. find the acceleration of the car

An object with a mass of 4.6 kg accelerates at 1.08 m/s/s when an unknown force is applied to it. What is the amount of the force?

Which is colder, 0 celsius or 20 fahrenheit

Consider the differential equation y′′+αy′+βy=t+e^ (4t). Suppose the form of the particular solution to this differential equation as prescribed by the method of undetermined coefficients is yp (t) = A1t^2+A0t+B0te^ (4t).

Which of these is an example of physical weathering? Rock breaking up due to carbonic acid Rock breaking up due to mechanical force

Determine the total mechanical energy of a 250 g baseball if it has a velocity of 30 m/s when it leaves the pitcher's hand 1.2m above the ground.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.
