Answer:
1. v1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (M L T−1) as momentum. In the International System of Units, these are kg⋅m/s = N⋅s.
2. Derivation. Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
3. It is defined as the ratio of tangential stress to the shearing strain, within the elastic limit. Its unit is N/m2 or Pascal and its dimensional formula is [ML-1T-2]. Compressibility of a material is the reciprocal of its bulk modulus of elasticity. Its SI unit is N-1m2 and CGS unit is dyne-1 cm2
4. 5. 6. 7. 8. 9. 10.
Every measurement has two parts. The first is a number (n) and the next is a unit (u). Q = nu. For Example, the length of an object = 40 cm. The number expressing the magnitude of a physical quantity is inversely proportional to the unit selected.
If n1 and n2 are the numerical values of a physical quantity corresponding to the units u1 and u2, then n1u1 = n2u2. For Example, 2.8 m = 280 cm; 6.2 kg = 6200 g.
i hope this will helpfull for you
