Answer:

no one is alive in this world everyone is dead from everywhere

Step-by-step explanation:

It’s neither. It’s closer to 3.14, but they’re both approximations

Answer:

Gravitational force = 6.673×10⁻¹⁰ N

Explanation:

If two objects A and B of masses 'M' and 'm' lie at a distance 'd' from each other, and the force of attraction between the two objects is 'F', according to the universal law of gravitation:

• The force between the two objects is directly proportional to the product of their masses,

                          F ∝ M×m

• And the force between two objects is inversely proportional to the square of the distance between them.

                          F ∝ 1/d²

• Which forms the equation:

                          F = GMm/d²,

where G = 6.673×10⁻¹¹ N m² kg⁻² is the universal gravitational constant.

Given:

Mass of one object, M = 4 kg

And the mass of the other object, m = 10 kg

They are separated by a distance, d = 2 m

The gravitational constant, G = 6.673×10⁻¹¹ N m² kg⁻²

Substituting the above values into the equation of law of gravitation:

[tex]F=\frac{GMm}{d^{2} }[/tex]

[tex]F=\frac{(6.673)10^{-11} (4)(10)}{2^{2} }[/tex]

⇒ F = 6.673×10⁻¹⁰ N

Mass of body a is Ma=2kg

Mass of body b is Mb=4kg

Mass of body cis Mc=1kg

Separation between a and b=2m

Let the body C be placed at a distance d fron the body A,

The gravitational force between A and C,

FAC=GMaMc/d^2=G*2*1/d^2=2G/d^2......1

the gravitational force between B and C is

FBC=GMbMc/d^2=G*4*1/(2-d)^2=4G/(2-d)^2

For body C the gravttatinal force =0

hence Fac=Fbc

2g/d^2=4G/(2-d)^2

(2-d)^2=2d^2

2-d=√2d

(√2+1)d=2

d=0.83m

Answer:

x=87° will be the answer of this question as the two horizontal lines are parallel because 57°and 57° are equal so the line sare parallel and angle W=87° will be equal to angle V=87° so angle TVY will be also 87° because they arevertically opposite angles.

Answer:

X = 87°

Step-by-step explanation:

• When two lines intersect, the vertically opposite angles so formed are equal.
• If two parallel lines are intersected by a transversal,

1. Each pair of corresponding angles is equal.
2. Each pair of alternate interior angles is equal.
3. Each pair of interior angles on the same side of the transversal is supplementary.

The angle 87° given in the figure and ∠UWV form vertically opposite angles.

We know that vertically opposite angles are equal,

∴ ∠UWV = 87°

∠UWV and x form a pair of corresponding angles, when transversal Y intersects the two parallel lines.

Since corresponding angles are equal,

x = ∠UWV

∴ x = 87°
