Answer: In this situation , the myocardial infarction is the medical diagnosis of the patient.
Explanation:
Medical diagnosis is the various steps that are being taken by a medical personnel to disease or condition of a patient with respect to the signs and symptoms observed. The steps taken by the medical personnel includes:
--> the Medical history of the patient,
--> physical examination is carried out on the patient.
--> diagnostic tests are equally performed..
Myocardial infarction which is also called heart attack is the medical diagnosis given when a blood clot blocks blood flow to the heart. In the physical examination of the patient, shortness of breath is a common signs of the condition. Hope this helps, thanks!
Answer:
See the explanation below.
Explanation:
53) Yes, this process is called latent heat transfer, it happens when heat is transferred to a body or a substance, an increase in its energy is observed without presenting an increase in temperature. An example of this can be seen in the evaporation of water.
54) It absorbs energy since heat transfer always occurs from a space of higher temperature to another with lower temperature so as the wax freezes the heat is transferred from the environment to the wax.
55) The water vapor and wet air will be absorbed by the canvas, the heat contained in this water vapor will be absorbed by the canvas in this way decreases the temperature of the water inside the canteen.
56) The process is vaporization. The refrigerant of the air conditioning equipment enters the coil, in the form of liquid, this liquid is at low temperature, so that the room air at a higher temperature, exchanges heat with the refrigerant liquid, the refrigerant liquid changes the phase of liquid to vapor, for when it is completely vaporized this can be sucked by the compressor equipment.
Answer:
58,800 Joules
Explanation:
I used the formula for Potential energy which is PE = mgh
200 kg x 9.8 m/s^2 x 30 m = 58,800 J
At the very tops of the rollercoaster is maximum PE which is 58,800 J and 0 J of KE, but at the very bottom is maximum KE (kinetic energy) which is 58,800 Joules but 0 J of PE. This is because energy can not be destroyed ONLY converted
Answer:
Nuclear fusion
Explanation:
This is because main sequence of star is powered by fusion of hydrogen to helium atoms together and this process releases energy. The energy released when the gas collapse into a protostar make the center of the protostar to be extremely hot. When the core becomes very hot, nuclear fusion can start.
Example of scalar: speed. Example of vector: velocity
Explanation:
In physics, there are two types of quantities:
- Scalar: a scalar quantity is a quantity having only magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:
Mass
Time
Speed
- Vector: a vector quantity is a quantity having both a magnitude and a direction. Examples of vector quantities in physics are:
Force
Acceleration
Velocity
The two types of quantities can be used in the same event, but in a different way. One of the most common example is the difference between speed and velocity.
In fact, let's consider an object moving in a uniform circular motion: it means that it is moving in a circle at a constant speed. The speed of the object measures only how fast the object is moving, but without telling anything about its direction of motion. The velocity, viceversa, also takes into account the direction of motion, and exactly for this reason, the velocity in a uniform circular motion is not constant, because the direction (it is a vector) is constantly changing. So, in a uniform circular motion, the speed is constant but the velocity is not.
