Answer :
Explanation :
Given that
Radius of sphere
The distance between the centers of the two spheres is
The charge of the sphere
The magnitude of the repulsive force between the charges pushing them a part is
Using coulomb law
Hence, this is the required solution.
We will solve this question using the second law of motion which states that force is directly equal to the product of mass and acceleration.
Where,
In our case,
<em>Thus, The force of 50000 Newton is required to accelerate a car of 2500 kg...~</em>
Answer:
32 °C.
Explanation:
Hola.
En este caso, debemos entender que la relación entre el calor y la temperatura viene dada por:
De este modo, dado que estamos estudiando la misma sustancia (agua) con masa constante, la relación calor-temperatura es lineal y directamente proporcional, por tal razón, si se duplica el calor suministrado, la temperatura también será duplicada, de modo que:
