The mass of the car at the given kinetic energy is 920 kg.
The given parameters;
initial velocity of the car, u = 22 m/skinetic energy of the car, K.E = 222,640 JKinetic energy if the energy acquired by a body during its motion. This kinetic energy is the product of average velocity squared and mass of the object.
The mass of the car at the given kinetic energy is calculated as follows;
[tex]K.E = \frac{1}{2} mv^2\\\\mv^2 = 2K.E \\\\m = \frac{2K.E}{v^2} \\\\m = \frac{2 \times 222,640}{(22)^2} \\\\m = 920 \ kg[/tex]
Thus, the mass of the car at the given kinetic energy is 920 kg.

what does auxiliary heat mean on a honeywell thermostat
Answer: Aux Ht or Auxiliary heat is the backup heat that turns on to help the compressor for first stage maintain your temperature setting. ... When the thermostat is in this position the compressor does not run, only the Emergency heat runs
Explanation:
What does auxiliary heat mean on a Honeywell thermostat.
Answer:What does aux heat mean on a Honeywell system? Short for auxiliary heat, this system is designed to heat your home up quickly instead of waiting for the cold heat pump on the exterior of your home. Unfortunately, using the auxiliary heat is significantly more expensive than using your heat pump.
Explanation:Aux on the thermostat stands for auxiliary heat. Auxiliary heat is the electric heat strip in your air handler that is supplemental heat. Emergency heat is the same thing as auxiliary heat. Auxiliary heat/ Emergency heat help the heat pump keep up when cold outside or the temperature differential on the thermostat is large.

atoms and molecules in matter are always_______
I think atoms and molecules in matter are always in motion because of kinetic energy.
Answer:
in motion.
Explanation:
In chemistry, we often explain the states of matter in terms of the kinetic molecular theory (KMT). The word kinetic refers to motion and the kinetic molecular theory suggests that atoms and molecules are always in motion. The energy associated with this motion is termed kinetic energy.
Point out the following about solids: The particles (atoms or molecules) are attracted to each other. The particles (atoms or molecules) vibrate but do not move past one another. The solid retains its shape.
They are not always in motion. They are always in motion if and only if the temperature of the surroundings is greater than absolute zero ( 0 K ).
Not only are molecules really small but they are in constant motion. The motion is called “thermal motion” because it's caused by temperature. Increase the temperature around them and the molecules move faster.

The graph in Figure 4.15 shows the position and time for two runners in a race. Who has the faster speed, Robin or Joel? Explain how to answer this question without doing calculations.
Answer:
Joel has the faster speed.
Explanation:
Joel has a steeper slope on the graph. The steeper a slope is, the faster speed will be. Therefore, Joel's slope is steeper which increases overall speed.
If you wanted to find an element that
would react similarly to chlorine (CI),
where would you look and why?
Answer: Fluorine (F) and chlorine (Cl) are two good choices. See reasoning below.
Explanation: Mendeleev arranged the elements in the periodic table in a manner that each group, or vertical column, contained elements that exhibited similar chemical properities. He even reserved spaces for undiscovered elements when none of the known elements had properties similar to those above or below the known elements in a group. An interesting event illustrates this property. In December 2010, NASA announced an important new discovery that was to be broadcast on live TV, creating much speculation (e.g., UFO's are real and we'll see the aliens sequestered at Roswell!!! I knew it.).
The actual announcement:
"Dec. 2, 2010: NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components."
A look at the periodic table shows arsenic just below phosphorus, in the same group. This was an unexpected find, but it might have been predicted with an understanding of how the elements are organized.

The precision of a balance is ±0.02 g. The accepted value for a measurement is 26.86 g. Which measurement is in the accepted range?
26.02 g
26.82 g
26.87 g
26.90 g
Explanation:
The precision of a balance is ±0.02 g.
The accepted value for a measurement is 26.86 g.
The accepted range is: =[26.86-0.02, 26.86+0.02] = [26.84, 26.88]So,26.87 g is correct

Explanation:
you push on box g that is next to box h, causing both boxes to slide along the floor, as shown in the figure. the reaction force to your push is
The reaction force to your push is the push of box G against you.
Newton's third law states that:
For every action, there is an equal opposite reaction.
So if an object x pulls or pushes an object y with a certain force, object y also exerts an equal and opposite force on object x.
Now, if you should push box G with a certain force, box G will exert an equal opposite force on you.
Hence, the reaction force to your push is the push of box G against you.

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air
resistance is equal to the force of gravity on the object. The forces on the falling object are
balanced. What will happen to the object and why?
Answer:
The object will contine to fall, but at a constant velocity. There will be no more acceleration.
Explanation: When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect. F = ma, and F (net) = 0. It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down). The metric term for this sudden resistance is "crash/bang/clunk/yieouch."

What does Newton's Second Law state and what are the formulas used?
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
