The components of a vector are the parts of the vectors that are what to each other.

How does the resistance of a 100w light bulb compare to the resistance of a 60w light bulb?

When you inhale (breathe in) your ribs move upwards and outwards and your diaphragm moves down. Explain in terms of pressure and volume how this process forces air into your lungs

Cold water (cp = 4180 J/kg·K) leading to a shower enters a thinwalled double-pipe counterflow heat exchanger at 15°C at a rate of 1.25 kg/s and is heated to 60°C by hot water (cp = 4190 J/kg·K) that enters at 100°C at a rate of 4 kg/s.

Bob is pushing a box across the floor at a constant speed of 1.5 m/s, applying a horizontal force whose magnitude is 60 n. alice is pushing an identical box across the floor at a constant speed of 3 m/s, applying a horizontal force.

A force of 1500 N is applied to a 1500 kg out. What is the acceleration of the car?

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.

Two students are looking at a brightly lit full Moon, illuminated by the reflected light from the Sun. Consider thefollowing discussion between the two students about what the spectrum of moonlight would look like.
