An experiment was conducted to determine how the diameter of a wooden dowel would affect the depth that the dowel would penetrate the sand. In a box containing 30kg of sand 80 gram weights were dropped from the height 15cm onto each of the five wooden dowels. The diameters of the wooden dowels were 2cm, 4cm, 6cm, 8cm, and 10cm. The amount of depth into the sand was measured using a ruler after each trial. Independent Variable: Dependent Variable: Control Variables: 1. 2. 3.

Answers

Answer 1

Answer:

Independent variable: The diameter of the wooden pins.

Dependent variable: The depth of the pins in the sand.

Control variable: height of 15 cm at which the pins will be thrown, boxes containing 30 kg of sand and weights of 80 grams.

Explanation:

An independent variable is one that does not need the influence of another variable to happen and that, its variation, influences that a measurable result occurs. In this case, as we know that the depth of the wooden pins is measured according to the influence of the diameter of these pins, we can say that the diameter of the wooden pins is the independent variable.

The dependent variable, on the other hand, is one that shows a measurable result through the influence of the independent variable. In this case, we can say that the depth of the wooden pins in the sand is the independent variable.

The control variable, in turn, is the factor that establishes an egalitarian environment in which the research will be established. In this case, the control variable is the height of 15 cm at which the pins will be thrown, the boxes containing 30kg of sand and the weights of 80 grams.

2- increasing accessibility to the internet (minor service costs)

3- higher living standards than previous generations

Explanation:

In the last years, many people have increased their access to information via electronic media, which represents a critical indicator of the 'openness' of a society. This phenomenon has brought a number of advantages including, for example, higher facilities and access to educational content, telemedicine services, etc. However, accessibility to electronic media is often associated with sedentary behavior and, consequently, it may lead to health problems. For example, it has been shown that the excessive use of electronic devices like electronic games negatively affects daily activities, and therefore may be associated with poorer children's socioemotional development.

Many individuals significantly improved their access to knowledge through digital communication, a vital sign of a general societal 'open-mindedness.'

Electronic media

Studies report that the differences in the time obese and lean people spend lying, sitting, standing, and moving account for about_______cals per day

Answers

Answer:

approximately 350-500 calories per day

Explanation:

It has been shown that obese and lean people's calorie needs are different despite having the same daily activities (for example, sitting and walking). These variations can be associated with different factors including height, weight, sex, age, physical condition, muscle mass, etc. At comparable body weight, lean people need less energy than obese. In this regard, it is important to note that people that have regular exercise routines burn fewer calories when doing the same activity. Moreover, lean people have proportionally more muscle mass than obese people, and thereby they are capable of burning more calories in the same unit of time.

It is B

Explanation:

this is because C says you hold it for 3 seconds and your walking backwards which is not true for doing a push up. A is standing and doing an exersice so thats not a push up. D is saying you lie on your stomach. Thats also not a push up.

Push-ups have just a minor direct effect on the abdominal region because they primarily target the muscles of the upper body. Thus, option B is correct.

What are the benefits of doing push-ups?

If and only if the calories burned during exercise are sufficient to convert fat loss and enhance abdominal muscle, push-ups can help reduce belly fat.

The push-up aids in strengthening and muscle growth across the upper body.

Improved cardiovascular health and greater shoulder joint support are two more potential advantages. Daily push-up practice does carry certain hazards, though. These include elbow injury, wrist pain, and lower back pain.

Targeted muscles include the pectoralis major in your chest, the triceps in your arms, and the shoulders (especially the scapular changing muscles).

Therefore, place palms shoulder-width apart describes the movement progression for a regular push-up.
