Pluto is a planet in our solar system whose orbit brings it inside the orbit of another planet.
What is the explanation for this?Numerous planets can be found in our solar system that Pluto is a member of. Pluto is a planet with an eccentric orbit that is highly oval in form and causes it to enter another orbit. It managed to enter Neptune's orbit. In comparison to Pluto, the dwarf planet, even Neptune can occasionally be far from the sun.
EThe events taking place on the planet are really unusual. In the years 1979 and 1999, it happens. Pluto, however, has never collided with Neptune. This occurs because Pluto only completes two of its three orbits around the sun, whereas Neptune completes three. This event stops two bodies from colliding.

The number of calories that you can eat a day without gaining weight depends on your activity level
For there to be a balance between the number of calories consumed through food and weight gain, it is important to maintain a good level of physical activity that helps us to maintain a healthy weight and at the same time does not allow an increase in weight and body mass.
All this is because the relationship between daily calories consumed and weight gain is directly proportional to the level of physical activity that we do.

A ball is thrown vertically downward with an initial speed of 15.8 m/s from a building whose height is 122 m. how long does it take for the ball to strike the ground?
A ball is thrown vertically downward with an initial speed of 15.8 m/s from a building whose height is 122 m. It takes the ball 3.63 s to strike the ground.
Vertical Motion:Because the object is moving downhill vertically, the motion has a negative acceleration value as well as a negative velocity value.
A quadratic function with concavity downwards can be used to represent both this kind of motion and the motion of the object thrown above.
Answer and justificationh = h0 - v0t - [tex]\frac{gt^2}{2}[/tex]
so putting all the values, we have,
0 = 122 - 15.8t - 4.9 [tex]t^{2}[/tex]
then we know the formula,
t= [tex]\frac{-b±\sqrt{b^2-4ac}}{2a}[/tex] here a=-4.9 b= -15.8 c =122

For a relative frequency distribution, relative frequency is computed is computed as ____________.
Answer:
For a relative frequency distribution, relative frequency is computed as the class frequency divided by the number of observations.
For an object being launched at ground level at a tilted non-zero initial velocity, is the velocity zero anywhere? are the horizontal or vertical components of the velocity zero at any point?
The correct answer No the velocity is not zero anywhere For an object being launched at ground level at a tilted non-zero initial velocity, and horizontal or vertical components of the velocity is zero at maximum height .
Because velocity is a vector (it has magnitude and direction), the overall velocity of an object can be calculated by adding the x and y components: v2 = vx2 + vy2. Meters are used to express horizontal and vertical distances (m). The horizontal velocity component (vx) describes the effect of velocity on horizontal displacement of the projectile.
The vertical velocity component (vy) describes the effect of velocity on vertical displacement of the projectile. The vertical component of a projectile's velocity is momentarily zero (vy = 0 m/s) when it reaches maximum height. The horizontal component of its velocity, however, is not zero.
