Answer: C
C. Place plastic around the metal wires, because electric charges
hardly move in plastic.
There are 3 states of matter. Solid, Liquid, Gas. An example of each would be ice, water, steam,
Now we know by Ohm's law that
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Introducing the constant of proportionality, the resistance,the Ohm's law can be mathematically represented as
V=I x R
Where V is the voltage measured in volts
I is the current measured in amperes
R is the resistance measured in ohms
Given:
I = 2 A
V= 110 V
Applying Ohm's law and substituting the given values in the above formula we get
V=I x R
110 = 2 X R
R = 55 ohms
Answer:
The correct answer is:
Cardio exercise (B)
Explanation:
The frequency, intensity, time and type (FITT) model is a model is planning exercises that incorporate the four elements to be considered when choosing a personal goal and fitness level. Cardiovascular exercises mainly involves aerobic exercises that are aimed at strengthening the heart and lungs and making the working muscles more efficient at the use of oxygen. They also increase stroke volume (volume of blood pumped per minute) and resting heart rate. The following are what the model entails and how they fit best with cardio exercises:
- Frequency: This has to do with how often exercises will be done. Depending on the goal cardio exercises are normally recommended as moderate exercises for five or more days a week, and intense cardio for three days a week
- Intensity: This has to do with how hard you work during exercises. For cardio exercises, the heart rate monitor, perceived exertion and talk test are done to measure the intensity of the exercise
- Time: This has to do with how long each exercise session will last. For cardio exercises, the recommendation is 30 to 60 minutes for each session.
- Type: This is the actual activity that is chosen during the sessions, and it is chosen to avoid overuse injuries or weight loss plateus. The type of actvities for cardio includes exercises that are aimed at increasing the heart rate, like running, walking, cycling dancing etc.
Answer:
Moving
Explanation:
energy in the form of motion; depends on the mass and velocity of the object.
Have a good day!
