The ovum, plural ovae (latin) produced in the female bodies of mammals ovaries are the female sex cells.
The sperm are the male sex cells. Produced in the testes.
When sperm and ovum meet, there is a chance that they could join together and thus start a new life. Process is called fertilisation
1450.4 newtons has to be applied so the object can move , because At average gravity on Earth (conventionally,g = 9.80665 m/s2), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple's weight.
Question: calculate their densties in Si unit.
200mg,0.0004m³
Answer:
0.5 kg/m³
Explanation:
Applying,
D = m/V........................ Equation 1
Where D = density, m = mass, V = volume.
From the question,
Given: m = 200 mg = (200/1000000) kg = 2.0×10⁻⁴ kg, V = 0.0004 m³ = 4.0×10⁻⁴ m³
Substitute these values into equation 1
D = (2.0×10⁻⁴ kg)/(4.0×10⁻⁴)
D = 2/4
D = 0.5 kg/m³
Hence the density in S.I unit is 0.5 kg/m³
Explanation:
(a) Impulse is force times time.
J = FΔt
J = (350 N) (0.12 s)
J = 42 Ns
(b) Change in momentum is equal to impulse.
J = Δp
Δp = 42 Ns
