    45.96 N
  • b)
    40.3 N
  • c)
    28 N
  • d)
    30 N

Concept:
Resolution of vectors into components: We have a vector (F) where the magnitude of the vector is F and the angle with horizontal is θ.
The vector has two components: 1. Vertical component and 2. Horizontal component
Vertical component (Fy) = F Sinθ
Horizontal component (Fx) = F Cosθ 
Calculation:
The horizontal component is responsible to move the stone along the ground.
Fx = 60cos60°  = 30 N
Hence, the effective value of the pull tending to move the stone on the ground is 30 N.

Analysis:
To find the effective force along the horizontal direction, we need to resolve the force applied by the child into horizontal and vertical components.

Given:
- Force applied by the child (F) = 60 N
- Angle made by the rope with the ground (θ) = 60 degrees

Calculations:
- Horizontal component of the force (F_horizontal) = F * cos(θ)
- F_horizontal = 60 * cos(60)
- F_horizontal = 60 * 0.5
- F_horizontal = 30 N

Therefore, the effective force along the horizontal direction is 30 N. Hence, option 'D' is the correct answer.

Directions:Read the passages and choose the best answer to each question.PassageYeast is a unicellular fungus, and is arguably one of the most important members of the fungus family, primarily because of its involvement in the process of fermentation.During this process, yeast breaks down sucrose into alcohol and carbon dioxide. The chemical equation for fermentation is given below. Scientists study how to induce fermentation in yeast most effectively.C12H22O11 + H2O → 4C2H5OH + 4CO2Experiment 1Since yeast needs sucrose to ferment and molasses is 60% sucrose, scientists first study yeast grown in molasses.Five test tubes are filled with .4 grams of yeast and various molasses concentrations. Carbon dioxide levels are measured as an indication of fermentation for each test tube after one day and again after two days. These levels are shown in Table 1.Experiment 2Five different test tubes are filled with .4 grams of yeast and various pure sucrose dilutions. Carbon dioxide levels are then measured as an indication of fermentation after one and two days. These levels are shown in Table 2.Experiment 3Eight more test tubes were filled with .4 grams of yeast and a 15% sucrose solution. Various combinations of ammonium sulfate, potassium dihydrogen phosphate, minerals, and vitamins were added to the test tubes. Carbon dioxide levels were measured after one and two days. These levels are shown in Table 3.Q.Based on Experiments 1 and 2, one can infer that, as compared to molasses, pure sucrose
