A charge of 8.4 × 10–4 C moves at an angle of 35° to a magnetic field that has a field strength of 6.7 × 10–3 T.
sineoko [7]

Answer:10842.33m/s

Explanation:

F=qvBsine

V=f/(qBsine)

V=(3.5×10^-2)÷(8.4×10^-4×6.7×10^-3×sin35)

V=10842.33m/s

Se deja caer un objeto desde la cornisa de una casa la cual tarda en llegar al suelo 645/500 segundos. ¿Cúal es la altura de la
salantis [7]

8.15m. La altura de la casa de la cual se deja caer un objeto que tarda en caer \frac{645}{500}s es de 8.15m.

La clave para resolver este problema es mediante caída libre, la velocidad inicial del objeto es 0 por lo que podemos calcular la altura h de la casa mediante la relación h= \frac{gt^{2}}{2}.

Conocemos la gravedad g=9.8\frac{m}{s^{2}} y el tiempo en que tarda en caer el objeto t=\frac{645}{500}s, sustituyendo los valores tenemos que:

h=\frac{(9.8\frac{m}{s^{2}})(\frac{645}{500}s)^{2}}{2}=8.15m

(b) Cable of a microwave oven has three wires inside it which have insulation of different colours black, green and red. Mention
MakcuM [25]
The green is ground.  Ideally, no current travels in this one.  The red and black are the power and neutral wires but which colors they are depends on a convention.  In the US, you will actually have a black (power) and a white (neutral)  Here it's red and black and usually in a red/black system the red is the power.  Either way there is a potential of 120V rms between them.
