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)

What is the acceleration of a car that travels in a straight line?

Sphinxa [80]

Acceleration occurs when there is a change in speed or direction. If it travels in a straight line, there is no speed or change in direction as it is constant througout, hence 0 acceleration.

hope this helps!! ✨

A rock falls for 1.43 seconds how far did it fall? The falls's velocity is an acceleration of -9.81 m/s2

BartSMP [9]

Answer:

$s = -0.100 \ m$

Explanation:

Generally from kinematics equations we have that

$s = ut + \frac{1}{2}gt^2$

Here u is the initial velocity of the rock and the value is 0 m/s given that there was no information that it was in motion before the fall

substituting 1.43 s for t and $-9.8m/s^2$ for g we have that

$s = 0 *1.43 + \frac{1}{2}(-9.8)*(0.143)^2$

=> $s = -0.100 \ m$

The negative sign show that the displacement is in the direction of the negative y-axis

A car is traveling in a circular curve on a horizontal road at constant speed. Name the force that is responsible for causing it

boyakko [2]

The correct answer is
<span>c the friction force from the road

In fact, the friction force between the road and the tires of the car acts as centripetal force, keeping the car in circular motion.</span>
