Describe what happens to matter

Temos os meios A e B. A luz no meio B com ângulo de incidência de 45º e n=V2, para o meio A com n=V3. Determine: a) o ângulo de refração; b) A velocidade da luz no meio A.

Many radioisotopes have important industrial, medical, and research applications. One such radioisotope is 60Co, which has a half-life of 5.2 yr and decays by the emission of a beta particle (energy 0.31 MeV) and two gamma photons (energies 1.

What is the law of physics

Can an object experience more than one force at a time

7. How much force is needed to give a 10-kg mass an acceleration of 35 m/s?

A rightward force of 302 n is applied to a 28.6 kg crate to accelerate it across the floor. thye coefficient of friction between the crate and the floor is 0.750. determine the acceleration

How the properties of sound waves change as they spread out in a spherical pattern

If legos are plastic can they be recycled?

At an accident scene on a level road, investigators measure a car's skid mark to be 93 m long. It was a rainy day and the coefficient of friction was estimated to be 0.35.

How does a shorter wavelength affect the frequency of a wave?
