Answer:

If density is greater, the object sinks. Saturn is mainly composed of the lightest two gases known, hydrogen and helium. It is the only planet in our solar system whose density is less than water

The kinetic energy of an object with a mass of 6.8 kg and a velocity of 5.0 m/s is [BLANK] J. (Report the answer to two signific
dmitriy555 [2]
<h2>Hello!</h2>

The answer is:

The kinetic energy of the object is equal to 85 J.

<h2>Why?</h2>

The kinetic energy involves the speed and the mass of an object in motion. We can calculate the following the work needed to speed an object (kinetic energy) using the equation:

KineticEnergy=\frac{1}{2}mv^{2}

Where,

m, is the mas of the object

v, is the speed of the object.

Now, we are given:

mass=m=6.8kg\\speed=v=5\frac{m}{s}

So, substituting and calculating the kinetic energy of the object, we have:

KineticEnergy=\frac{1}{2}*6.8kg*(5\frac{m}{s})^{2}

KineticEnergy=\frac{1}{2}*6.8kg*(25\frac{m^{2}}{s^{2}})

KineticEnergy=\frac{1}{2}*170kg\frac{m^{2}}{s^{2}}

KineticEnergy=85kg\frac{m^{2}}{s^{2}}=85J

We have that the kinetic energy of the object is equal to 85 J.

Have a nice day!

Whats the height and temp for tropopause​
Rainbow [258]

The height for the tropopause is the tropopause is about 20 km (12 miles or 65,000 feet) above sea level. It's temperature typically, drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet).

A wave is turned back when it meets the boundary of the medium in which it is traveling. The wave is said to have undergone
kondor19780726 [428]

Answer:

The wave is said to have undergone reflection.

Explanation:

When a wave traveling through a medium meets the boundary of that medium, it gets bounced back and returns into the medium in which it is traveling. This behavior of the wave that causes a change in the direction of the wave is known as reflection. Examples of reflection include the reflection of sound waves, light waves, water waves, etc.

According to the law of reflection, the angle at which the waves approach the barrier (or an interface between two mediums) equals the angle at which they reflect off the barrier (or an interface between two mediums).

Refraction of waves is referred to the change in the direction of waves or bending of the path of the waves when they pass from one medium to another which is accompanied by a change in wavelength and speed of the waves.

Diffraction of waves is referred to the change in the direction of waves when they move around a barrier in their path or pass through an opening.  Interference occurs when two waves traveling through the same medium superpose to form a wave having the same or lower or greater amplitude.

Label these as balanced or unbalanced:
kvasek [131]

Answer:

  1. A book lying on a table  - Balanced force
  2. An airplane cruising in level flight  - Balanced
  3. A rock falling from a cliff  - Unbalanced force
  4. A bridge collapsing in an earthquake  -  Unbalanced force
  5. A man sitting on a park bench  - Balanced force
  6. A space shuttle taking off  - Unbalanced force
  7. A car maintaining a constant speed on a straight road  - Balanced force
  8. An airplane landing - Unbalanced force

Explanation:

Usually, one or more forces act on a body at an instant of time. When these forces acting on a body and bring the body in the equilibrium position, the force is said to be balanced. The unbalanced force changes the equilibrium state of the body.

As in the case of an airplane cruising in a level flight, the weight of the plane will be equal to the lift force and the thrust is equal to the drag. So the plane is experiencing a balanced force.
