Answer:
answers the correct one is C
Explanation:
For this exercise we must use the projectile launch ratios
the expressions for the initial velocities are
sin θ =v_{oy} / vo
cos θ = v₀ₓ / vo
v_{oy} = v₀ sin θ
v₀ₓ = v₀ cos θ
Range and flight time are requested
the expression for the scope is
R = 
We calculate for each angle
θ = 45º
R₄₅ = \frac{ v_{o}^2 \ sin 90}{g}
R₄₅ = v₀² / g
θ = 60º
R₆₀ = \frac{ v_{o}^2 \ sin 120}{g}
sin 120 = sin 60
R₆₀60 = sin 60 R₄₅
as the sine function has values between 0 and 1, the range for this angle is less
Flight time is twice the time it takes to reach maximum altitude
v_y = v_{oy} - gt
at the point of maximum height there is no vertical velocity vy = 0
t = v_{oy} / g
t = v₀ sin θ / g
θ=45º angle
t₄₅ = sin 45 v₀/g
t₄₅ = 0.707 v₀/g
θ=60º angle
t₆₀ = sin 60 v₀/ g
t₆₀ = 0.86 v₀/g
the answer for this part is
R₄₅ > R₆₀
t₄₅ < t₆₀
when reviewing the different answers the correct one is C
Answer:
Answer is (b) Mercury, venus and Mars.
Explanation:
Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.
Answer:
The Jovian planets formed beyond the Frostline while the terrestrial planets formed in the Frostline in the solar nebular
Explanation:
The Jovian planets are the large planets namely Saturn, Jupiter, Uranus, and Neptune. The terrestrial planets include the Earth, Mercury, Mars, and Venus. According to the nebular theory of solar system formation, the terrestrial planets were formed from silicates and metals. They also had high boiling points which made it possible for them to be located very close to the sun.
The Jovian planets formed beyond the Frostline. This is an area that can support the planets that were made up of icy elements. The large size of the Jovian planets is as a result of the fact that the icy elements were more in number than the metal components of the terrestrial planets.
