Scalar quantities include:

distance

speed

time

energy

Scalar quantities change when their magnitude changes.

Vector quantities

Vector quantities have both magnitude and direction. For example, 11 m east and 15 ms-1 at 30° to the horizontal are both vector quantities.

Vector qualities include:

displacement

velocity

acceleration

force

weight

momentum

Vector quantities change when:

their magnitude changes

their direction changes

their magnitude and direction both change

Name two skills a centre must have to be effective at his/ her positions

Answers

Answer:

paint defense and paint offense

Explanation:

In all, a center needs to be good in the paint.

Answer: The centre is usually the team’s tallest and strongest player and is positioned under the basket. He is also required to be physically domineering with more physical strength and athleticism.

On the offensive play, most centres do not consistently score midrange or beyond the arch. Instead, most of their points should be from offensive rebounds and are also required to block defenders to open other players up for driving to the basket.

On the defence, the centre is responsible for keeping the opponent from shooting by blocking shots and passes in the vital area. They’re also expected to fight for rebounds as they’re usually taller physically.

What body type has a slower metabolic rate and does not tolerate carbohydrates well?

Answers

Answer:

fat

Explanation:

Those with an endomorph body type have a lower tolerance to carbs compared to both mesomorphs and ectomorphs. Endomorphs are good at converting carbohydrates into sugar and storing them as fat. Because of this, they may be more prone to insulin resistance than the other body types.

Endomorph is a body type that has a slower metabolic rate and does not tolerate carbohydrates well.

One of the three somatotypes (body types) based on body shape and metabolic traits was called an endomorph by psychologist William Sheldon in the 1940s.

It's critical to keep in mind that, despite the fact that somatotypes offer a broad classification of body types, individual variations in metabolism and response to carbs might range greatly. How a person's body reacts to food and how their metabolism works are strongly influenced by lifestyle choices, genetics, and general health. Therefore, rather than depending simply on somatotype classifications, it is crucial to concentrate on balanced nutrition and frequent physical exercise customized to individual needs and goals.

Hence, endomorph is a body type that has a slower metabolic rate and does not tolerate carbohydrates well.

True or False Sensory Memory takes in all the information from your five senses

Answers

Answer:

True

Explanation:

Sensory memory is the shortest-term element of memory. It is the ability to retain impressions of sensory information after the original stimuli have ended. It acts as a kind of buffer for stimuli received through the five senses of sight, hearing, smell, taste and touch, which are retained accurately, but very briefly. For example, the ability to look at something and remember what it looked like with just a second of observation is an example of sensory memory.

explain why less vitamins c is a lost when vegetables are plunged into boiling water​

Answers

Answer:

High heat can reduce the vitamin C content of the vegetables, and when heat and water are combined, as they are in boiling, you can see significant reduction of vitamin C. (One study found that boiling reduced the vitamin C content in broccoli by 45 to 64 percent.) This is because the vitamin is first leached out of the food into the water, and then degraded by the heat.

1) What is Muscular Power?

2) Why is muscular power sometimes more important than strength for many competitive
activities?

3) What is the difference between aerobic and anaerobic power?

Answers

Answer:

1) The ability to exert a maximal force in as short a time as possible, as in accelerating, jumping and throwing implements. While strength is the maximal force you can apply against a load, power is proportional to the speed at which you can apply this maximal force. Broad jump test.

A example: While strength is the ability to exert force, power is the ability to exert force rapidly. For example, muscular strength is what it takes to push through a heavy set of barbell squats, and muscular power is the explosiveness it takes to jump up and dunk a basketball.

2) sorry can’t find the answer for this question☹️.

3) Aerobic means 'with air' and refers to the body producing energy with the use of oxygen. Anaerobic means 'without air' and refers to the body producing energy without oxygen. This is typically exercise that is performed at a higher intensity. There are two ways that the body can produce energy anaerobically. The biggest difference between aerobic and anaerobic exercise lies in how the body gets its energy. For anaerobic exercise, the muscles will use stored energy sources to fuel itself rather than oxygen, which includes breaking down glucose. Aerobic exercise, however, requires continuous and peak oxygen consumption.
