Determine the units of a, b, c and d. What physical quantities they represent. All have SI units.

Answer

Mass of the Sun is $2.0 \times 10^{30}$ Kg and radius of sun is $7.0 \times 10^{8}$m. Express the density of sun. Also explain why the order of magnitude of density of sun is in the range of solids and not in the range of liquids and gases?

Answer

A physical quantity X is connected from $X=\frac{a{{b}^{2}}}{C}$ . Calculate the percentage error in X, when % error in a, b, c are 4, 2, and 3 respectively.

Answer

Percentage error in the measurement of height and radius of cylinder are $x$ and $y$ respectively. Find the percentage error in the measurement of volume. Which of the two measurements height or radius needs more attention?

Answer

Orbital radius of mercury around the sun is 0.38 A.U. Find the angle of maximum elongation for mercury and its distance from earth when the elongation is maximum.

Answer

Convert 4.29 light years into parsecs. Calculate the parallax of a star at this distance when viewed from two locations of earth six months apart in its orbit around the sun.

Answer

In an experiment, on determining the density of a rectangular block, the dimensions of the block are measured with a Vernier calipers (with a least count of 0.01 cm) and its mass is measured with a beam balance of least count of 0.1 g. The measured values are Lenght(L) = 5.12 cm, Breadth(b) = 2.56 cm, thickness(t) = 0.37 cm and mass(m) = 39.39 g.How do we report our result for the density of the block.

Answer

It is required to find the volume of a rectangular block. A Vernier callipers is used to measure the length, width and height of the block. The measured values are 1.37 cm, 4.11 cm, and 2.56 cm respectively.
