B. Helium because it is constantly being made in the sun

Explanation:

From the given paragraph, we can conclude that helium is the most common element in a star such as the sun because it is constantly being made.

In the nuclear fusion process that results in the production of helium, hydrogen nuclei are the reactants and helium is the product.

  • since the reactants are constantly being used in the core of the sun, this suggests that the products must be more.
  • The reaction requires a high temperature and pressure to initiate.
  • It is a series of chain reaction that uses a fuel of hydrogen to produce helium.

The table represents the forces on four objects, with directions. Object F1 ↑ F2 → F3 ← F4 ↓ W 30 N 20 N 20 N 30 N X 15 N 35 N 2
Reika [66]

When the magnitude of all opposing forces is equal, then the force is called balanced. The forces on W and Y are balanced while the forces on X and Z are unbalanced.

<h2>Net Force:</h2>

It is defined as the vector sum of all forces acting on the object. The forces with the same magnitude in the opposite direction cancel each other.

<h3>Balanced force: </h3>

When the magnitude of all opposing forces is equal, then the force is called balanced.

<h3>Unbalanced force: </h3>

When a force is more than the opposing force, the force is called unbalanced.

Therefore, the forces on W and Y are balanced while the forces on X and Z are unbalanced.

As shown in the diagram below, a rope attached to a 500.-kilogram crate is used to exert a force of 45 newtons at an angle of 65
kaheart [24]

Answer:

19.01 N

Explanation:

F = Force being applied to the crate = 45 N

\theta = Angle at which the force is being applied = 65^{\circ}

Horizontal component of force is given by

F_x=F\cos\theta\\\Rightarrow F_x=45\times \cos65^{\circ}\\\Rightarrow F_x=19.01\ \text{N}

The horizontal component of the force acting on the crate is 19.01 N.
