Answer with Explanation:
Kailangan nating sumunod sa batas dahil<em> ito'y para sa ating kapakanan at kaligtasan.</em> Ginawa ang batas <em>upang maging mapayapa ang ating pamayanan</em> kaya tungkulin nating sundin ito. Pinipigilan ng batas na abusuhin ang ating mga karapatan. Sinisiguro nito na <em>ligtas tayong maninirahan nang walang takot</em> at <em>patuloy nating itataguyod ang ating buhay nang walang inaapakang tao.</em> Dahil dito, nararapat lang na kilalanin ng tao ang batas at taos-pusong sundin ito.
Answer:
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
Explanation:
The momentum of a photon is:
p = E/c
E = the photon energy
c = the speed of light.
take the time derivative (gives the force)
F = dp/dt = (dE/dt)/c
F = 2(dE/dt)/c (is doubled for complete reflection of the light)
Intensity has the units of energy per unit time per unit area
= I
then,
Force/unit area = 2I/c
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
Answer:
Explanation:
Let
h = height of balloon (in feet).
θ = angle made with line of sight and ground (in radians).
h = 300 tanθ
now can be written as
When θ = π/4,
