Answer:
3.1216 m/s.
Explanation:
Given:
M1 = 0.153 kg
v1 = 0.7 m/s
M2 = 0.308 kg
v2 = -2.16 m/s
M1v1 + M2v2 = M1V1 + M2V2
0.153 × 0.7 + 0.308 × -2.16 = 0.153 × V1 + 0.308 × V2
= 0.1071 - 0.66528 = 0.153 × V1 + 0.308 × V2
0.153V1 + 0.308V2 = -0.55818. i
For the velocities,
v1 - v2 = -(V1 - V2)
0.7 - (-2.16) = -(V1 - V2)
-(V1 - V2) = 2.86
V2 - V1 = 2.86. ii
Solving equation i and ii simultaneously,
V1 = 3.1216 m/s
V2 = 0.2616 m/s
Answer:
28.9 seconds
Explanation:
Convert km/hr to m/s.
83.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 23.2 m/s
16.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 4.56 m/s
Given:
Δx = 400 m
v₀ = 23.2 m/s
v = 4.56 m/s
Find: t
Δx = ½ (v + v₀) t
400 m = ½ (4.56 m/s + 23.2 m/s) t
t = 28.9 s
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.
