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)
The magnitude of other charge will be 1 × 10⁻² coulomb
The formula of electrostatic force is
Electrostatic force = K q1 q1 / r²
where k is the coulomb's constant whose value is 9 × 10⁹
q1 and a2 are the magnitude of charges
and r is the distance between them
magnitude of the force given to us is 9.0 × 10⁻⁵ newtons
magnitude of one charge = 1.0 × 10⁻⁶ coulomb
Force = K q1 q2 / r²
9.0 × 10⁻⁵ = ( ( 9 × 10⁹ ) × ( 1.0 × 10⁻⁶ ) × q2 ) / 1
9.0 × 10⁻⁵ = 9 × 10³ × q2
10⁻² = q2
Charge on q2 is 1 × 10⁻² coulomb
So the magnitude of the second charge is came out to be 1 × 10⁻² coulomb after applying the formula of electrostatic force.

Answer:
Isotope of carbon-12.
Explanation:
The MOLE is a unit of measurement of the amount of a pure substance which contains exactly the same number of chemical units which could be (Atoms, molecules etc.) posses atoms in exactly
grams of isotope of carbon-12 (i.e.,
).
So, The mole is the Notation used for an amount
as same the 12 number is used for dozen for making count of Bananas and many more.
The
is known as the fundamental constant names Avogadro's number (
), It is in the honor of Italian scientist Amedeo Avogadro.
Transformation of energy, because energy cannot be created or destroyed
Answer:
P.E = 4.398 Joules.
Explanation:
Given the following data;
Spring constant, k = 71.8N/m
Displacement, x = 0.35m
To find the elastic potential energy;
The elastic potential energy of an object is given by the formula;
Substituting into the equation, we have;
Elastic potential energy = 4.398 Joules.
<em>Therefore, the elastic potential energy of the spring is 4.398 Joules. </em>
