Answer:14 m
Explanation:
Given
Vertical jump make by the dolphin is given by
Suppose the dolphin jump with an initial velocity of
so u is given by
If dolphin launches at an angle then maximum horizontal range is given by
assuming the of Dolphin to be Projectile so range is given by
substitute the value of
Range will be maximum for
thus
Gravitational force or gravitational pull involves the attraction between objects with mass
Answer:
Req = 50 Ω
Explanation:
The equivalent resistance is basically the sum of all the resistances in a circuit.
The sum of these resistances will depend whether these resistance are in series or parallel.
If the resistances are on series, the expression to use is:
R = R₁ + R₂ + R₃ + .......Rₙ (1)
If the resistances are on parallel then the expression to use is:
1/R = 1/R₁ + 1/R₂ + ........1/Rₙ (2)
Now, according to the picture, we have R₁ and R₄ in series, so here we have to use (1):
R₁₄ = 10 + 30 = 40 Ω
R₂ and R₃ are in parallel so we use (2):
1/R₂₃ = 1/20 + 1/20 = 2/20 = 1/10
R₂₃ = 10 Ω
Finally, R₁₄ and R₂₃ are in series (Because of the sum of the resistance in each side, they are now forming one resistance in each side), therefore, we use (1) again to get the equivalent resistance of the whole circuit:
Req = 10 + 40
<h2>
Req = 50 Ω</h2>

Answer:
Ionic compound
Explanation:
Barium Chloride is an ionic compound of barium and chlorine.
Barium is a metal with two valence electrons while chlorine is a non metal with seven valence electrons.
Barium will require two atoms of chlorine to form Barium chloride.
The reaction can be demonsated in the equation below.
Ba2+ + Cl- -----------> BaCl2
In this type of bond, Barium uses its 2 valence electrons to form an ionic bond with 7 valence electrons of chlorine. Chlorine will require its own two atoms to form this type of bond with Barium.
Cl -Ba-Cl = BaCl2
Decreases because the lower the temperature the less active the particles are
