Answer:
round object that orbits the Sun but lacks the ability to clear the neighborhood around is orbit.
Explanation:
It is true that a dwarf planet is a round object that orbits the Sun but lacks the ability to clear the neighborhood around its orbit.
Due to the size of a dwarf planet, it does not possess enough gravitational attraction or force to clear the orbit around it or other bodies.
One of the notable dwarf planets is Pluto. It was formerly thought to be planet but it has since been delisted.
Pluto's orbit lies beyond that of Neptune.
Answer:
Vy = 0
y(max) = 137,76 m
x(max) = 318 m
Explanation:
We are dealing with a projectile movement
And from problem statement we know:
θ = 60⁰ then sin θ = sin 60⁰ = √3/2 and cos 60⁰ = 1/2 and g = 9.8 m/sec²
V₀ = 60 m/sec
V₀x = V₀ *cosθ Vx = V₀x Vx = Constant then Vx = V₀ *cosθ
Then Vx = 60* 1/2 Vx = 30 m/sec
V₀y = V₀ *sinθ ⇒ V₀y =60*√3/2 ⇒ V₀y = = 30*√3 m/sec
Vy = V₀y * sin θ - g*t
When Vy = 0 (maximum height point) we are half of the way for the ball to hit the ground, then
Vy = 0 ⇒ V₀y - g*t = 0 ⇒ 30*√3 (m /sec) = 9,8 (m/sec²)* t
t = 30*√3/9.8 t = 5.30 sec
y(max) = y₀ + V₀y*t - 1/2 * g*t²
By substitution:
y (max) = 0 + 30*√3 * 5.30 - 0,5* 9.8* (5.3)²
y(max) = 275,40 - 137,64
y(max) = 137,76 m
And finally x(max)
x(max) = Vx *t = 30* 2*5,3
x(max) = 318 m
Answer: Producers have the greatest amount of available energy.
When an organism eats another organism, it gains energy.
Explanation:
A food chain is a linear sequence of transfer of food and energy when one organism is eaten by the other organism. A food web is the interconnection of two or more food chains. This happens when one organism belong to one food chain also consume organisms of same food chain or other food chain. A food chain includes trophic levels on the basis of the mode of feeding of the living beings.
Among the options given, Producers have the greatest amount of available energy. and
When an organism eats another organism, it gains energy. are correct.
Producers are the organism which are capable of producing their food either through photosynthesis or chemosynthesis. They are present at the base level of the food chain. They consist of large amount of energy as compared to all the trophic levels in the food chain.
When one organism eats other organism it gains energy because of the assimilation and digestion of the organism as food.
2 hours because 15 miles is one hour and the trip was 30 miles. 30 divided by 15 is 2.
