The solution for this problem is:
r = [(2.90 + 0.0900t²) i - 0.0150t³ j] m/s²
this is for t in seconds and r in meters
v = dr/dt = [0.180t i - 0.0450t² j] m/s²
tan(-36.0º) = -0.0450t² / 0.180t
0.7265 = 0.25t
t = 2.91 s is the velocity vector of the insect
No, one more group must get the same result as the other group. This will make it more reliable and reproducible.
Type motion examples and subtypes
electromagnetic radiation disturbance propagating through electric and magnetic fields (classical physics) or the motion of photons (modern physics) radio waves, microwaves, infrared, light, ultraviolet, x-rays, gamma rays
Hope this helps and please mark me as brainlest and like:)
The answer is A) velocity, because velocity is speed and displacement.
Hope this helps
Explanation:
Given that,
Diameter = 10 cm
Distance = 2 m
Speed 
Speed 
Pressure in main pipe
(I). We need to calculate the diameter
Using equation of continuity





(II). We need to calculate the pressure the gauge pressure
Using Bernoulli equation




(III). If it is possible to carry water to a faucet 17 m above ground,
Using Bernoulli equation


Here, 
Put the value in the equation


Hence, This is required solution.
