Except for Pluto, all of the planets in the solar system have slightly elliptical orbits.    

Pluto, a dwarf planet, the orbit is highly elliptical, with an eccentricity of 0.25, and it travels between 4.4 and 7.4 109 kilometers (2.7-4.6 109 miles) from the Sun on average. As a result, Pluto's orbit occasionally brings it closer to the Sun than Neptune, which implies that sometimes Pluto is much closer to the Sun than other times.

Pluto orbits the Sun at an angle of 17 degrees. This indicates that Pluto occasionally orbits above the other planets and occasionally orbits below them.

Explanation:

I will assume 7.5 m/s

When the Kinetic Energy is entirely converted to Potential energy the max height will have been reached

KE = PE

1/2 m v^2 = mgh     divide by m

1/2 v^2 = gh         looking for  h     so divide both sides by

1/2 v^2 / g   = h      sub in the values   using g = 10 m/s^2

1/2 ( 7.5 )^2 / 10  = 2.8125 m

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The volume of the cylindrical metal bar;

V₁=πr²h

V₁=3.4 × 7² × 484 cm

V₁=80,634.4 cm³

The one side of the box is,220mm(22 cm)

V₂ = a³

V₂ = (22)³

V₂ = 10,648 cm³

The no of boxes is found as;

Plane Motion One of the most common examples of motion in a plane is Projectile motion.

The particle would have the longest De Broglie wavelength traveling with the same velocity, which has lesser frequency.

What is wavelength?

The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.

Wavelength λ = c/f

where c is the speed of light in vacuum = 3*10⁸ m/s

As, the wavelength and frequency are inversely related to each other. When the wavelength is longer, the frequency will be lesser to the same value of speed of wave.

Thus, the particle with less frequency has longest De Broglie wavelength.

Explanation:

The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.

The equation that we can used to determine the frictional force using the coefficient of kinetic friction and the normal force is given by the expression : F = u N.

Where N is the normal force by the weight of the body.

Frictional force is a type of force acting on a body to prevents its motion. Hence, the frictional force is always negative. Frictional force acting on an object is making a resistance to the motion of the object.

There are both kinetic frictional force and static frictional force. The coefficient of frictional force is the ratio of the frictional force to the normal force on the object. The normal force on the object is equal to m g that is the force by its own weight.

If u is the coefficient of kinetic friction and N be the normal force acting on the object, then the force of kinetic frictional force F is given by,

F = u N.

Where N = mg.

Given that;

First, we convert 1.00 oz to qt

32 oz = 1 qt

1.00 oz = x

x = 1.00 / 32

x = 0.03125 qt

Now, we convert 0.03125 qt to liter

1.0567 qt = 1 L

0.03125 qt = x

x = 0.03125 / 1.0567

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level but liquid pressure is exerted on the surface of an object in a liquid.

And they also differ in formulas. We can calculate atmospheric pressure in two ways. First we can get the atmospheric pressure by an instrument called barometer. And the second one is by usin this formula, atmospheric pressure = density of mercury x acceleration due to gravity x height of column of mercury. But this equation will only work if the atmospheric pressure is being measured by mercury.

But the formula for liquid pressure is defferent and the instrument used to measure the liquid pressure is also defferent.

The instrument used to measure the liquid pressure is pressure gauge. And the formula for the liquid pressure is density x height x gravity. Please give me a like and thank me.
