Answer = C
It blows towards the poles from the sub-tropical high pressure areas
Answer: option C. 43.9°
Explanation:
Refer to the diagram. The tension in the two strings is equal T₁=T₂=T = 3 N
The strings support a frame weighing, W= 4.26 N
We will write the tension in the strings as the sum of their horizontal and vertical components.
The horizontal components balance each other and cancel out.
T₁ cos θ = T₂ cos θ
On the other hand, The vertical component would support the weight of the frame.
2 T sin θ = W
2 × 3 N × sin θ = 4.16 N
sin θ = 0.693
⇒ θ = sin ⁻¹(0.693) = 43.9°
Hence, the angle made by two wires with the horizontal is 43.9°.
By definition, Newton's First Law, also called the Law of inertia, indicates that "Every body perseveres in its state of rest or of uniform rectilinear motion unless it is forced to change its state by forces impressed on it."
This means that for a body to come out of its state of rest or of uniform rectilinear motion, it is necessary for a force to act on it.
<h3>Definition of inertia</h3>
So, in other words, all bodies are opposed to changing their state of rest or motion and this opposition is called inertia.
<h3>Body in equilibrium</h3>
In this way, a body is in equilibrium when the resultant of the forces acting on it is zero. That is, it is not possible for a body to change its initial state (be it rest or motion) unless one or more forces intervene.

Answer:
Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid pressure using the equation liquid pressure = mass x acceleration due to g density x depth in fluid.
si unit is pascal
