Answer:
The horizontal component of the 70 N force = 35·√3 N
The vertical component of the 70 N force = 35 N
Explanation:
The magnitude of the given force, F = 70 N
The angle of inclination of the given force to the horizontal, θ = 30°
By the resolution of forces, we can resolve the given force, F, into its horizontal component, Fₓ, and vertical components,
, as follows;
The horizontal component of the given force = Fₓ = F × cos(θ)
Substituting the values, we have;
The horizontal component of the 70 N force, Fₓ = 70 × cos(30°) = 35·√3 N
The vertical component of the given force =
= F × sin(θ)
Substituting the values, we have;
The vertical component of the 70 N force,
= 70 × sin(30°) = 35 N.
Knowing that the a and b represents red and blue spheres respectively.The chemical equation we could make isL5A2 + 5B --> 4A2B + A2 + B as shown in boxes
Simplifying this would make it:
4A2 + 4B --> 4A2B
Thus, reducing the coefficients, the final answer is:
A2 + B --> A2B
pshyical change is a usually reversible change of a substance, as size or shape: Freezing a liquid is a physical change. Compare chemical change.
internal change is when the movement of the particles increases
specific latent heat is the amount of energy per kg (unit mass) required to change ice to water without change in temperature.
D should be the correct answer.
