Answer:
i think ww
Explanation:
i think we need to calculate net force which is:
net force=m.a
..nf=1000kg×30m/s
therefore net force will be the answer you get whwn you multiply those two
Correct option B
Transverse waves are those waves whose particles vibrate perpendicular to the direction of wave.

Answer: the constant angular velocity of the arms is 86.1883 rad/sec
Explanation:
First we calculate the linear velocity of the single sprinkler;
Area of the nozzle = π/4 × d²
given that d = 8mm = 8 × 10⁻³
Area of the nozzle = π/4 × (8 × 10⁻³)²
A = 5.024 × 10⁻⁵ m²
Now total discharge is dived into 4 jets so discharge for single jet will be;
Q_single = Q / n = 0.006 / 4 = 1.5 × 10⁻³ m³/sec
So using continuity equation ;
Q_single = A × V_single
V_single = Q_single/A
we substitute
V_single = (1.5 × 10⁻³) / (5.024 × 10⁻⁵)
V_single = 29.8566 m/s
Now resolving the forces as shown in the second image,
Vt = Vcos30°
Vt = 29.8566 × cos30°
Vt = 25.8565 m/s
Finally we calculate the angular velocity;
Vt = rω
ω_single = Vt / r
from the given diagram, radius is 300mm = 0.3m
so we substitute
ω_single = 25.8565 / 0.3
ω_single = 86.1883 rad/sec
Therefore the constant angular velocity of the arms is 86.1883 rad/sec
Answer: water
The light reactions of noncyclic photophosphorylation takes place in the chloroplast.
The light energy is converted to chemical energy to produce both ATP and NADPH,
which act as energy-transfer molecules in the light-independent reactions of
the Calvin cycle. The addition of phosphate due to synthesizing of ATP by cells
results to photophosphorylation.
Moreover, <span>the electrons from water replenish chlorophyll molecules that
have given up electrons by photolysis. The two electrons from the water
molecule are kept in photosystem II, while the 2H+ and 1/2O2 are
left out for further use.</span>
