Answer:
minimum initial velocity is 21.35 m/s
Explanation:
given data
distance S = 30 m
height h = 30 m
maximum acceleration a = 2 m/s²
to find out
minimum initial velocity that your friend could have thrown the object to enable you to catch
solution
first we get here time with the help of second equation of motion
time = 
..................1
put her value we get
time = 
time = 5.477 second
and that is time which tossed object must be take so we apply here again second equation of motion that is
-S = ut - 0.5 × gt² .......................2
-30 = u× 5.477 - 0.5 ×9.8×5.477²
solve it we get
u = 21.35 m/s
so minimum initial velocity is 21.35 m/s
Answer:
1,4,3and 2 would happen hope this helps
Explanation:
i1=1ampere
i1+i2=I
VA−VB=i1×3Ω=i2×6
⇒1×3=i2×6
2i=21ampere
Hence I=i1+i2=1+0.5=1.5ampere
Req=2+3+63×6=2+93×6=4Ω
equivalent circuit

From KVL
1req=v
v=1.5×4
Bird habitats include various habitat types: from the human-related environment (e.g., building area, park, rural area, farmland, and pond) to the natural-related environment (e.g., forestland, grassland, river, stream, and coastland).
Answer:D.
Real, inverted, smaller than the object, and closer to the mirror than the object
Explanation: Real images will be inverted. As it is beyond the centre of curvature it is also beyond 2F which means that the image is inside the centre of curvature ( between F and 2F from the mirror ) As the image is closer to the mirror than the object it must be diminished in size
