An electric toaster takes in electrical energy from the power outlet and converts it into heat, very efficiently. If you want your toast to cook quickly, you need a toaster that radiates as much heat as possible each second onto your bread

A toaster converts electrical energy to heat (or thermal) energy.  A toaster is an electrical device used for making toasts. The process involves putting pieces of bread in the slots of a toaster and using electricity to heat them. The heat is provided by coils that heat up due to passage of electricity and we end up with toasted bread or simply, toast.

Amy gets up from her seat on a train to move closer to the front. Just as she begins to walk forward, the train stops at a stati
Ivahew [28]
Have you ever been in a bus, a train, or a car ?
What happens to you when it stops suddenly ?

A body in motion continues in motion unless
an external force acts on it and makes it stop.

Amy's body keeps moving forward when the train stops.
She pitches forward, and if she doesn't reach out and grab
a seat or a seated person, she may lose her footing and fall
on her face.

Choice - 'A' is a very good explanation.
The other choices aren't.

'C' is a good hunch, but it only applies to her feet.
The rest of her keeps going.

'D' is nonsense.  There are no mysterious forces of
'repulsion' or 'attraction' on the train.

El peso normal de un estudiante de secundaria es 725 N y el área de los dos zapatos que usa es de 412 cm2 . La presión medida qu
kotykmax [81]

Answer:

Presión = 175,97 N/m²

Explanation:

Dados los siguientes datos;

Peso del alumno (fuerza) = 725N

Área de zapatos = 412 cm² a metros cuadrados = 412/100 = 4.12 metros

Para encontrar la presión, usaríamos la siguiente fórmula;

Presión = fuerza / área

Presión = 725 / 4.12

Presión = 175,97 N/m²

An air-filled capacitor consists of two parallel plates, each with an area of 7.60 cm2, separated by a distance of 1.60 mm. If a
nata0808 [166]

Answer:

Explanation:

(a) For the calculation of the Electric field we use

E=\frac{V}{d}=\frac{15.0V}{1.6*10^{-3}m} =9375\frac{N}{C}

(b) The capacitance is calculate by using the expression

C=\frac{\epsilon_{0}A}{d}=\frac{8.85*10^{-12}C^{2}/(Nm^{2})*(7.6*10^{-4}m^{2})}{1.6*10^{-3}m}=4.2*10^{-12}C

(c) Finally, the charge on each plate is

Q=CV=(4.2*10^{-12}C)(15V)=6.3*10^{-11}C

I hope this is useful for you

Regards
