(a) What is the tension in the cable

Answers

Answer:

Explanation:

Given that:

distance (z) = 7.86 m

mass of the person = 81.7 kg

Acceleration (a) = 0.729 m/s²

By using Newton's second law along the vertical axis:

[tex]T - mg = ma\\ \\ T = ma + mg \\ \\ T = m(a+g) \\ \\[/tex]

T = 81.7 (0.729 +9.8)

T = 860.22 N

as vy₀ = v₀sin45 and vx₀ = v₀cos45 and are equal.

0 = d + ½g(d²/v₀²cos²45)

-d = ½g(d²/v₀²cos²45)

weak base i think since it’s a lower ph

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.

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

Ti3N + MgO → Mg3N2 +Ti2O balance chemical equation

We have that the balanced chemical equation   is mathematically given as.

2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2O

From the question we are told

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_2O

We consider the Left hand side(LHS) first.

2Ti_3N + 3MgO → Mg_3N_2 +Ti_2O

Then we consider the right hand side RHS.

2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2O

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
