Answer is: C. Thermal.

Thermal energy is type of energy can be transferred in three different ways:

1) direction contact through collisions (also called conduction).

2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection).

3) by waves traveling with or without a medium (also called radiation).

According to the equation, 2 H2 + O2 --> 2 H20, how many moles of oxygen are required to convert 12 moles of hydrogen to wate

DerKrebs [107]

Answer:

6 moles of oxygen, or 3O2.

Explanation:

I would build a proportion for this:

$\frac{2(2)}{2} = \frac{12}{x} \\ 4x = 24 \\ x = 6$

What is the kinetic energy of a 5 kg object moving at 7 m/s?

valina [46]

Answer:

122.5 Joule, or 122.5 j

Explanation:

Given,

mass of the object (m) = 5 kg

velocity of the object (v) = 7 m/s

Kinetic energy = $\frac{1}{2}$ × m × v²

Applying the formula:

Kinetic energy = $\frac{1}{2}$ × 5 × 7²

⇒ $\frac{1}{2}$ × 5 × 7 × 7

⇒ $\frac{245}{2}$

⇒ 122.5 Joule, or 122.5 j

Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.

PLZ HELP!<br><br> How do you think changing the angle of a ramp will affect work done?

kogti [31]

Answer: The steepness of a ramp affects it by making it easier or harder.

Explanation: It's a bit situational. If you were going up a steep ramp with a heavy load, it will increase the work necessary, whereas if you were going down a ramp, it would decrease the work necessary. If you need this simply put, think about biking up and down a hill. It would be easier going down than up.
