What requirements must be met for a nuclear fu- sion reaction to occur? A select all that apply. A extremely low temperatures C extremely high temperatures D a large amount of pressure

Nuclear fission and nuclear fusion are important nuclear processes that result in a change in the nucleus of isotopes. (a) Compare nuclear fission and nuclear fusion, and explain two similarities be- tween them. (b) Describe two ways nuclear fission and nuclear fusion differ regarding require- ments for reactions and applications. You can start your response with: - Nuclear fission and nuclear fusion are similar in that they both ... - Two ways in which nuclear fusion differs from nuclear fission are...

A magnetic pole face has a rectangular section having dimensions 200 mm by mm . If the total flux emerging from the pole is \( 150 \mu \mathrm{~Wb} \), calculate the flux density. ( 4 marl

Suponha que, neste experimento, os cavalos de Thompson exercessem uma força F, ao mesmo tempo que, a cada segundo, deslocavam uma distância de 3 metros. Se em 1,6 horas, 19 litros de água tiverem sido aquecidos de uma temperatura inicial de \( 20^{\circ} C \) até uma temperatura final de \( 100^{\circ} C \), calcule o valor da força F realizada pelos cavalos. Suponha, para isso, que todo o trabalho realizado pelos cavalos seja convertido em energia térmica da água. Considere que o calor específico da água vale \( c_{a g u a}=1 \) cal \( / g^{\circ} C \), que \( 1 c a l=4,18 \mathrm{~J} \) e que a densidade da água é de \( 1 \mathrm{~g} / \mathrm{mL} \) (ou seja, cada litro corresponde a 1000 g de água).

What is the force on a 1000 kg elevator that is falling freely at \( 9.8 \mathrm{~m} / \mathrm{sec}^{2} ? \)

HW 1: Name Clarabelle Barraza student ID: 1. In major league baseball, the pitcher's mound is 60 feet from the batter. If a pitcher throws an \( 85 \mathrm{~m} / \mathrm{h} \) fastball, how much time elapses from when the ball leaves the pitcher's hand until the ball reaches the batter? Solve it in the unit of second.
