please help! need a answer as quick as possible please. i need help with questions 1 and 2 ! thank you
Answer:
1.)When you arrive from school and you smell cookies baking in the kitchen your brain will tell you that you are hungry and that you should go to the kitchen at that point your sense organs like your nose helps you to detect that something is baking(cookies)and your nervous system (brain)will tell you that you are hungry and it will command/direct your brain to go to the kitchen then for you to eat the cookies and drink the milk the digestive system is going go help you to chew,swallow and digest the food which has been taken and when you also run to the kitchen at the beginning your brain will direct your skeletal and muscular system because the skeletons and muscles work hand in hand,and when you finish your meal the body will circulate some nutrients or minerals from the food or snack taken to other parts of the body for energy.
2.)When you sleep the whole body is asleep except the heart which needs to continue circulating blood around the whole system and sometimes the brain may not rest when you are sleeping it may continue to do it's work that's why some people usually sleep walk or sleep talk,it means the brain is not at rest and still doing some things....Thank you for the question I hope it is very useful to you.
What is the formula for acceleration? ( PLEASE HELP! ALSO IF YOU GET B IT'S WRONG BECAUSE I ALREADY PUT THAT AND IT WAS WRONG sorry caps)
A: Final speed-initial speed ________________________ time
B: Net force = Mass x acceleration
C: Mass x Velocity
D: Force a 5N Force B 10N Net force of forces A and B 15N
Answer:
option A is correct
Explanation:
acceleration the time rate of change of velocity or speed so
a=Δv/t
Δv=vf-vi
Δv= final speed-initial speed
now a=final speed-initial speed/time

what are benefits of better cardio-respiratory endurance?
Answer: By strengthening cardiorespiratory endurance your body will be able to take in and carry more oxygen. This will result in an increased number of red blood cells and hemoglobin. Your heart rate will also become stronger and be able to pump out larger volumes of blood and distribute the oxygen better.
Explanation:
larger arteries that are able to carry blood throughout the body

The blade of a metal cutter is shorter than that of the scissors used by tailor.why
Answer:
It depends on the amount of pressure needed to cut your material. Metal is a tougher material to cut though, so the blades must be shorter to create more pressure to break through the metal. Cloth on the other hand is easier to cut through so the blades can be longer in order to cut more in each snip.

A football coach walks 24 meters eastward, then 12 meters
westward, then 36 meters eastward, and finally 22 meters
westward.
Whats the distance
Magnitude and direction
Answer:
Distance magnitude = 24 meters
The direction of the displacement = Eastward
Explanation:
The distance walked by the football coach eastward = 24 meters
The distance walked by the football coach westward = 12 meters
Then the distance walked by the football coach eastward = 36 meters
Finally, the distance walked by the football coach westward = 22 meters
The total distance walked by the coach eastward = 24 + 36 = 60 meters
The total distance walked by the coach westward = 12 + 22 = 34 meters
Taking x-direction as positive, we have;
The magnitude of the distance = 60 - 34 = 24 meters,
The direction of the coach = Eastward.

High blood pressure can lead to all of the following except: Question 3 options: A) stroke B) vision loss C) aerobic fitness D) heart attack
Answer:
C) Aerobic Fitness
Explanation:
High blood pressure doesn't affect your aerobic fitness.
High blood pressure can lead to stroke, vision loss, and heart attack except in aerobic fitness. Therefore, option (D) is correct.
What is High blood pressure?High blood pressure can be described as a condition in which the force of the blood against the artery walls is too high. Usually, hypertension can be defined as blood pressure above 140/90 and can be severe if the pressure is above 180/120.
High blood pressure generally develops over time. It can occur because of an unhealthy lifestyle, or not getting enough physical activity. Certain health conditions, such as diabetes can also increase the risk of leading to high blood pressure. In high blood pressure, the force of the blood pushing against the artery walls is too high and the heart works harder to pump blood.
High blood pressure has no common symptoms. Over time, if untreated, it can cause health conditions like heart disease and stroke. Eating a healthy diet with less salt, regularly exercising, and taking medications can lower blood pressure.

Anna wanted to see what battery lasts the longest she put each batter into a clock and recorded the time that the clock stopped she use their sale energizer Kroger brand and everybody what is the constant
Answer:
The resistance of the clock circuit.
Explanation:
In electricity, the potential difference or voltage is the drive force. It is known as the electromotive force in a battery or generator. The potential difference is the difference in the higher terminal and the lower terminal of the circuit. The potential difference forces electrons to move in an orderly fashion, from the higher potential to the lower potential; this flowing electrons is what is called the current of the circuit. When the electrons flow, they meet a certain amount of resistance. This resistance is unique to the material of the circuitry, and does not change in a circuit. The value of the resistance of the circuit remains the same, even when the potential difference of the electrical energy source is depleted, and current stops to flow.

1.Round off the following measurement to the three significant figures. 1.296 g.
2. How many significant figures are there in the following measurement? 2020 g.
3.Round off the following measurement to the three significant figures. 5.658 grams
Answer:
1) 1.30g2) 3 sf3) 5.66 gramsExplanation:
1) Significant figure means the amount of figure we are interested in. Note that 0 is insignificant. For example 30 is a one significant figure i. e the only figure of interest is 3.
Given the figure 1.296 g, as we can see, there are initially for figures in the value. This means we are to eliminate one to make it 3. To do that we will remove the 6 at the back by round it up to 1 and add it to the value of 29 preceding it to give 30. The figure will become 1.30 (to 3sf).
Note that only values greater than 4 are rounded up to 1 and added to the preceding value
2) Given the figure 2020, the number of significant figures present is 3 significant figure. Note that all zeros at the end of a value are considered insignificant hence the only significant value here is 202 (which is 3 sig fig.)
3) For the figure 5.658, the value to 3sf is 5.66 (Note that the value of 8 at the end is rounded up to 1 and added to 65 to make it 66). This is as explained in the first answer above.
What is the density of a 500 g rectangle block with the following dimensions: Length = 8.0 cm, Width = 6.0 cm,
and Height = 5.0 cm. I
Explanation:
Density = mass / volume
ρ = (500 g) / (8.0 cm × 6.0 cm × 5.0 cm)
ρ = 2.1 g/cm³
The volume of the block the product of its dimensions that is 240 cm³. Then density of the block weighing 500 g is 2.08 g/ cm³.
What is density ?Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed within a given volume. It is the ratio of mass to the volume.
Volume of an object is the space occupied by the object. For a rectangle block, volume is the product of length, width and height.
Given, l = 8 cm
width = 6 cm
h = 5 cm
volume = l w h = 6 cm × 5 cm × 8 cm = 240 cm³
Mass of the block = 500 g
density = mass/ volume
d = 500 g/240 cm³
= 2.08 g/cm³
Therefore, the density of rectangular block is 2.08 g/cm³.

Subtract 2.5×10^-5 from 8.0×10^-3 with regards to significant numbers.
Answer:
8.0 x 10⁻³
Explanation:
(8.0×10⁻³) - (2.5×10⁻⁵)
= (8.0×10⁻³) - (2.5 × 10⁻² x 10⁻³) (factor out 10⁻³)
= 10⁻³ [ 8 - (2.5 x 10⁻²) ]
= 10⁻³ [ 8 - 0.025 ]
= 10⁻³ [ 7.975 ]
= 7.975 x 10⁻³
however we can observe that both original numbers are expressed to 2 significant figures, hence we must express our answer also in 2 significant figures by rounding 7.975 to 8.0, thereby giving us:
8.0 x 10⁻³
