Answer:
6 V.
Explanation:
We'll begin by calculating the equivalent resistance of the circuit. This can be obtained as follow:
Resistor 1 (R₁) = 3 Ω
Resistor 2 (R₂) = 3 Ω
Equivalent Resistance (R) =?
Since the two resistor are in parallel connection, the equivalent resistance can be obtained as:
R = (R₁ × R₂) / (R₁ + R₂)
R = (3 × 3) / (3 + 3)
R = 9/6
R = 1.5 Ω
Finally, we shall determine the total voltage in the circuit. This can be obtained as follow:
Current (I) = 4 A
Equivalent Resistance (R) = 1.5 Ω
Total voltage (V) =?
V = IR
V = 4 × 1.5
V = 6 V
Thus, the total voltage in the circuit is 6 V

If the tension in the string is equal to 2 W when the stone is at its lowest point, then the tension when the stone is at the highest point will be
Answers
This question involves the concept of tension, centripetal force, centrifugal force, and weight.
The tension of the stone at the highest point is "0 N".
The centrifugal force always acts away from the circle. The tension always acts toward the support that is the center of the circle in this case. When the stone is at its lowest point, the centrifugal force, and the weight of the stone, both act downward. But the tension is pointing in the upward direction. Hence, the equilibrium equation will be:
[tex]Tension = Weight\ + \ Cenrifugal\ Force\\T = W + F_c\\T = 2\ W\ (given)\\2\ W = W+F_c\\F_c = 2\ W - W\\F_c = W[/tex]
Now, we consider the stone at the top position. Here, the centrifugal force will act in the upward direction (away from the center of the circle), while the weight and tension will be acting in the downward direction. Thus, the equilibrium equation, in this case, will be:
[tex]F_c = W+T\\T=F_c-W\\T = W-W\\[/tex]
T = 0 N

The weight of an object is 180 N at a distance of 150 km above a planet's center. What is the weight of the object when it moves 450 km above the center of the planet?
Answers
By using Newton law of gravitation, the weight of the object when it moves 450 km above the center of the planet is 20N
Given that the weight of an object is 180 N at a distance of 150 km above a planet's center.
F = GMm/[tex]r^{2}[/tex]
F = mg = 180N
r = 150
When it moves 450 km above the center of the planet, G, M and m will be constant. only r will vary.
180 = GMm/[tex]150^{2}[/tex]
Make GMm the subject of the formula
GMm = 180 x 22500
GMm = 4050000
As it moves 450 km above the center of the planet, Its weight will be
F = GMm/[tex]r^{2}[/tex]
Substitute all the values and parameters
F = 4050000/[tex]450^{2}[/tex]
F = 20 N
Therefore, the weight of the object When it moves 450 km above the center of the planet is 20 Newtons

Answers
A substance with a pH value of 2.3 would be classified as a strong acid. Option A is correct.
What is ph value?pH stands for "potential hydrogen," and it is a measure of the acidity or basicity (alkalinity) of a solution. The pH scale ranges from 0 to 14, with 7 being neutral (neither acidic nor basic). Solutions with a pH less than 7 are considered acidic, and solutions with a pH greater than 7 are considered basic.
Here,
The pH scale is used to measure the acidity or basicity of a solution. Values on the pH scale range from 0 to 14. Solutions with a pH value less than 7 are considered acidic, and solutions with a pH value greater than 7 are considered basic. The lower the pH value, the more acidic the solution.
A pH value of 2.3 indicates that the solution is strongly acidic, as it is well below the neutral value of 7.

Ti3N + MgO → Mg3N2 +Ti2O balance chemical equation.
Generally the way to balance an equation is by making all elements present on the Left hand side(LHS) same with the right hand side RHS.
Therefore
The equation is mathematically given as.
Ti_3N + MgO → Mg_3N_2 +Ti_2OWe consider the Left hand side(LHS) first.
2Ti_3N + 3MgO → Mg_3N_2 +Ti_2OThen we consider the right hand side RHS.
