What is different about the rotation of Uranus?
Trava [24]

Answer:

Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.

Explanation:

the axis is vertical

What is an example of kinetic energy at work,1 a ball lodge in the tree, 1 a frisbee flaying in the air, 3 a car in the garage
AfilCa [17]

Answer:

a frisbee flaying in the air

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where;

  • K.E represents kinetic energy measured in Joules.
  • M represents mass measured in kilograms.
  • V represents velocity measured in metres per seconds square.

Hence, an example of kinetic energy at work is a frisbee flaying in the air because it would possess energy due to its motion in the air.

A balloon has a volume of 6.2 liters at 23.2 C. The balloon is then heated to a temperature of 144.0 C. What is the volume of th
Marina CMI [18]

Answer:

8.7 L

Explanation:

T2(V1/T1) = V2

417.15 K(6.2 L/296.45 K) = 8.7 L

Remember to almost always change celcius to kelvin. Also, this is part of Charle's Law (temp and volume are proportional, so if temp increaces so must the volume or vice versa). Lastly, Charle's Law has the formula of V1/T1 = V2/T2. I just rearranged it to go along with your problem. Hence, the T2(V1/T1) = V2

How are force, mass, and motion related?
Sonja [21]
Force causes all motion, and the larger the mass of an object the stronger the force needs to be to accelerate the object.
