Answer:

There are two types of bone marrow – red bone marrow (myeloid tissue) and yellow bone marrow (fatty tissue). Red bone marrow is involved in production of blood cells, while yellow marrow is important for fat storage. As you age, yellow bone marrow replaces red bone marrow.

Sergeeva-Olga [200]

Answer:

Acceleration of the boy a₁:

$a_{1} = 1.87 \frac{m}{s^{2} }$

Explanation:

Conceptual analysis

We apply Newton's second law to the boy and the girl:

F = m*a (Formula 1)

F : Force in Newtons (N)

m : mass in kilograms (kg)

a : acceleration in meters over second square (m/s²)

Nomenclature

m₁ : boy mass

m₂ : girl mass

a₁ : boy acceleration

a₂ : girl acceleration

F₁ : boy acceleration

F₂ : girl acceleration

Known data

m₁ = 57 kg

m₂ = 41 kg

a₂ = 2.6 m/s²

Problem development

We apply to Newton's third law of action and reaction, then:

F₁ = F₂ , We apply the formula (1):

m₁*a₁ = m₂*a₂

$a_{1} = \frac{m_{2}* a_{2} }{m_{1} }$

$a_{1} = \frac{41* 2.6 }{ 57 }$

$a_{1} = 1.87 \frac{m}{s^{2} }$

ad-work [718]

Answer:

69.42 m

Explanation:

From the question given above, the following data were obtained:

Initial velocity (vᵢ ) = 4.9 m/s

Acceleration (a) = 4.2 m/s²

Time (t) = 4.7 s

Displacement (Δx) =?

Thus, we can obtain the displacement by using the following formula:

Δx = vᵢt + ½at²

Δx = (4.9 × 4.7) + (½ × 4.2 × 4.7²)

Δx = 23.03 + (2.1 × 22.09)

Δx = 23.03 + 46.389

Δx = 69.419 ≈ 69.42 m

Thus, the distance travelled is 69.42 m
