Si se aplica una fuerza de 3n sobre un sistema se genera 15000 cal de calor generandose a su vez un trabajo de 300 j ¿en cuanto
Marizza181 [45]

Answer: +/- 71,65 Calorías

Explanation: Se deduce que la fuerza aplica para aumentar o disminuir la energía del generador.

+/- x Calorías

X = Equivalente de 300 Joules en calorías

Para poder pasar Joules a calorías.

Hacemos una regla de 3 simple

1 Calorías = 4,18 Julios

0,2392 calorías = 1 Julio

(  1 / 4,18 = 0,2392 calorías)

300 Julios = 71,65 calorías

(0,2392 calorías x 300 julios = +/- 71,65 calorías)

Natalia lifts a bag of groceries 0.50 m by exerting a force of 36 N. How much work did she do on the bag?
Kruka [31]
<h3><u>Answer;</u></h3>

18 Joules

<h3><u>Explanation;</u></h3>
  • <em><u>Work is the measures the transfer of energy when an object moves over a given distance.</u></em>
  • Work is therefore given by; Force × distance

Force =36 Newtons

Distance = 0.5 meters

  • Hence; <em>work = 36 N × 0.5 N</em>

<em>                                = 18 Joules </em>

A string is vibrating between two posts as shown above. Students are to determine the speed of the wave within this string. They
kow [346]

Answer:

The distance between two posts

Explanation:

As the students have already measured the amount of time necessary for the wave to oscillate up and down that is on the string between two posts,They have to measure the speed of the wave.

        ie  v=fλ

<em>They have to measure distance between the posts. </em>

Because wavelength is equal to the distance between the posts ie full length of string.

The frequency of the wave is calculated by

               f= 1/T

Where is the time period which the students have calculated ie the amount of time taken to oscillate up and down,

Thus the wave speed is calculated using formula

            v=λ/T
