55 m/s is the answer if nothing has changed it will come back the same speed it was thrown up. Have an amazing day!
Answer:
v = 31.3 m / s
Explanation:
The law of the conservation of stable energy that if there are no frictional forces mechanical energy is conserved throughout the point.
Let's look for mechanical energy at two points, the highest where the body is at rest and the lowest where at the bottom of the plane
Highest point
Em₀ = U = m g y
Lowest point
= K = ½ m v²
As there is no friction, mechanical energy is conserved
Em₀ =
m g y = ½ m v²
v = √ 2 g y
Where we can use trigonometry to find and
sin 30 = y / L
y = L sin 30
Let's replace
v = RA (2 g L sin 30)
Let's calculate
v = RA (2 9.8 100.0 sin30)
v = 31.3 m / s

Cardiorespiratory fitness improves the efficiency of the cardiovascular and the respiratory systems in delivering oxygen to the body.
Please select the best answer from the choices provided.
True
False
The correct answer to this question is True
Explanation:
The cardiorespiratory system (cardiovascular and respiratory system) includes structures and organs such as the heart, the lungs, the veins, etc. that are involved in the process of oxygenation of the body. This process can be less or more efficient depending on different factors. One of these is the cardiorespiratory fitness or the ability of the body to work effectively in terms of oxygenation during exercise or effort.
In this context, a higher cardiorespiratory fitness means the cardiorespiratory system will work more efficiently, while low fitness implies less efficient oxygenation. Additionally, this fitness can be improved through activities such as running, hiking, among others. Therefore, cardiorespiratory fitness improves efficiency in the process of oxygenation, which makes the statement true.
Answer:
b. 48.0 g.
Explanation:
Given;
mass of the exoplanet,
radius of the exoplanet,
The acceleration due to gravity of the planet is calculated as;
Therefore, the correct option is b. 48.0 g
Thermal energy moves between objects through conduction. This is because, collisions made from the objects through the molecules.
Heat can also move in three different ways. Convection, conduction, and radiation.
