Answer:
θ=19.877⁰
Explanation:
Given data
Velocity Va=34.0 km/h
Velocity Va=100 km/h
To find
Angle θ
Solution
We want the bird to fly with velocity Vb=100 km/h with an angle θ relative to the ground so that the bird fly due south relative to the ground.From figure which is attached we got
Sinθ=(Va/Vb)
Sinθ=(34.0/100)
θ=Sin⁻¹(34.0/100)
θ=19.877⁰
Answer: c opinion is something ppl just suggest but a theory needs proof before it is confirmed
EM stands for ElectroMagnetic.
Answer: 800 km/h
Explanation:
Use equation for average speed
V=S/t
where S is distance
t is time
S=4800Km
t=6h
---------
V=S/t
V=4800Km/6h=800 Km/h
