- If it’s possible for an object to go faster than the speed of light, why doesn’t it just keep a According to our current understanding of physics, as described by Einstein's theory of relativity, objects with mass cannot accelerate to o... 1
- An object moves along the circle with normal acceleration proportional to tα Answer: P ∝ t^(α-1) Normal (centripetal) acceleration is a_n = dfracv²R . It is given that a_n = k t^α , so v² = kR t^α ⇒ v = √(kR) t^(α/2)... 1
- Four particles of mass 1kg are placed on four coners of a square of side 1m. What is the center of mass of this system? Given: Mass of each particle, m = 1 kg Side length of the square, a = 1 m The coordinates of the four corners of the square are: A(0, 0), B(... 1
- A car is running at 12 m/s the force of the car is 1000 N , what is the mass of the car? To determine the mass of the car, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by a... 1
- How do you stop focusing on others too much and kind your beeswax? Stopping yourself from focusing too much on others and minding your own business involves a combination of self-awareness, mindset shifts, a... 1
- How do I calculate momentum? Momentum is calculated using the formula: Momentum (p) = Mass (m) × Velocity (v) Where: Momentum (p) is measured in kilogram meters per seco... 1

- Define ‘t’ test. Explain the different situations where paired and unpaired ‘t’ tests applied The t-test is a small-sample test (population SD unknown) that checks whether a mean, or the difference between two means, is statistically... 1
- Discuss- Histogram, Bar diagram. A histogram represents a continuous frequency distribution with touching bars; a bar diagram represents discrete or categorical data with se... 1
- Briefly describe the different distribution patterns of data. Data can be distributed in different shapes: symmetric (normal), positively skewed, negatively skewed, uniform, bimodal/multimodal and J-sha... 1
- Explain one way ANOVA and the assumptions in one way ANOVA. One-way ANOVA compares the means of three or more groups that differ in one factor, using F = MSB/MSW ; it assumes independence, normality a... 1
- Explain chi square test for Goodness of fit. The chi-square goodness-of-fit test checks whether observed frequencies agree with the frequencies expected from a theoretical distribution,... 1
- Explain with examples- Histogram, Pie chart. A histogram shows the frequency distribution of continuous (numerical) data using adjacent bars; a pie chart shows how a whole is divided in... 1
- Explain ANOVA and its significance. ANOVA (Analysis of Variance) tests whether three or more population means are equal by splitting the total variation into variation between... 1
- Explain student‘t’ test and its applications. Student's t-test is a test of significance for means when the sample is small (usually n < 30 ) and the population standard deviation is unk... 1
- Describe the various of graphical methods of representing quantitative data. The main graphical methods for quantitative data are the histogram, frequency polygon, frequency curve, ogive, stem-and-leaf plot, box plot,... 1
- Explain the hypothesis testing using one way of ANOVA. One-way ANOVA tests H₀: μ₁ = μ₂ = dots = μ_k by comparing the variance between group means with the variance within groups through F = MSB/M... 1
