The crust is the thinnest layer of the Earth. The fossils are most probably be found in this layer because it is the outermost layer. Also, the deeper the layer of the Earth, the higher the temperature that it has, and it probably cannot preserve the fossil.

900J

Explanation:

Given parameters:

Specific heat of the aluminium = 900Jkg⁻¹K⁻¹

Mass of aluminium = 0.5kg

temperature change = 2K

Unknown:

Quantity of heat = ?

Solution:

The quantity of heat a body absorbs to cause a change in temperature is given as:

H = mcΘ

H is the quantity of heat

m is the mass of the substance

c is the specific heat capacity

Θ is the temperature change

H = 0.5 x 2 x 900 = 900J

The 'G' in the universal gravitation formula

shutvik [7]

b. Gravitational constant

Explanation:

G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.

The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".

Mathematically, the law is expressed as:

F = G $\frac{m_{1} m_{2} }{r^{2} }$

Where F is the gravitational force

G is the gravitational constant

r is the distance

m is the mass 1 and 2 bodies
