The loading ramp at a delivery service is 12 feet long and makes an 15latex: ^\circ∘ angle with the horizontal. if the ramp is replaced with a ramp 19 feet long, what angle does the new ramp make with the horizontal?

 θ2 = 9.4º

Explanation:

For this execution we will use the trigonometry relationships

For the first ramp let's calculate the vertical height where it arrives that is constant

      sin θ = y / L

      y = L sin θ

      y = 12 sin15

      y = 3,106 feet

With this height we can calculate the angle of the second ramp

       sin θ₂ = y / L₂

       θ2 = sin⁻¹ (y / L₂)

       θ2 = sin⁻¹ (3,106 / 19)

       θ2 = 9.4º

the angle of the new ramp is 9.4º

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
