6.	Taking the mass of earth as 6.4×10²⁴m, Calculate the value of acceleration due to gravity at a height of 2000 km above the surface of Earth?
Answer» GIVEN :- MASS of earth = 6.4 × 10²⁴ Height from surface of earth = 2000 km To FIND :- The ACCELERATION due to gravity Solution :- we know that, $\sf g = \dfrac{Gm}{r^{2}}$ here, g = acceleration due to gravity; G = Universal GRAVITATIONAL Constant r = distance $\sf g = \dfrac{6.67 × 10^{-11} × 6.4 × 10^{24}}{2000^{2}}$ $\sf g = \dfrac{6.67 × 6.4 × 10^{13}}{4 × 10^{6}}$ $\sf g = \dfrac{6.67 × 1.6 × 10^{13}}{10^{6}}$ thus, the acceleration due to gravity is $\sf \dfrac{6.67 × 1.6 × 10^{13}}{10^{6}}$ $\:$ #sanvi....

Taking the mass of earth as 6.4×10²⁴m, Calculate the value of acceleration due to gravity at a height of 2000 km above the surface of Earth?

Answer»

GIVEN :-

MASS of earth = 6.4 × 10²⁴

Height from surface of earth = 2000 km

To FIND :-

The ACCELERATION due to gravity

Solution :-

we know that,

$\sf g = \dfrac{Gm}{r^{2}}$

here,

g = acceleration due to gravity;
G = Universal GRAVITATIONAL Constant
r = distance

$\sf g = \dfrac{6.67 × 10^{-11} × 6.4 × 10^{24}}{2000^{2}}$

$\sf g = \dfrac{6.67 × 6.4 × 10^{13}}{4 × 10^{6}}$

$\sf g = \dfrac{6.67 × 1.6 × 10^{13}}{10^{6}}$

thus, the acceleration due to gravity is $\sf \dfrac{6.67 × 1.6 × 10^{13}}{10^{6}}$

✏️ Answer:-

★ Work DONE to displace an object at 50° angle with RESPECT to a DIRECTIONAL applied force will be - (4/5)² F.∆x.

✏️ Explanation:-

★ We KNOW that,

Work done = Force × displacement

i.e., W = F × s

=) W = F→ . ∆x→

=) W = F.∆x × cos 50°

=) W = 0.64 F.∆x

=) W = 64/100 F.∆x

=) W = 16/25 F.∆x

42.	Prove the law of sine using a cross product
Answer» Answer: Sine law can be proved by using Cross products in Vector Algebra. Cross product between TWO VECTORS is the AREA of a PARALLELOGRAM formed by the two vectors as the sides of the parallelogram. ... On taking the RECIPROCAL of this, a / Sin A = b / Sin B = c / Sin C. This is the Sine law.

45.	Wat is Kolbel reaction
Answer» Answer: Kolbe reaction, also KNOWN as Kolbe Schmitt Reaction is a type of addition reaction named after Hermann Kolbe and Rudolf Schmitt. When phenol is treated with sodium hydroxide, phenoxide ION is generated. The phenoxide ion generated is more reactive than phenol towards electrophilic aromatic substitution reaction. HENCE, it undergoes electrophilic substitution reaction with carbon dioxide, which is a weak electrophile. Ortho-hydroxybenzoic acid (salicylic acid) is formed as the primary product. This reaction is POPULARLY known as Kolbe’s reaction. HOPE IT HEPLS! BRAINLIEST PLZ!
