Answers

Answer 1

Answer: 1 2 5

Explanation:

Answer 2

Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.

What represent correct variations of the formula for speed?

Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).

That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.

Therefore,  For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

In a paragraph, contrast the characteristics between anorexia and bulimia

Answers

Bulimia nervosa is similar in many ways because the individual is obsessed with their weight and wants to continuously lose weight to achieve their idea of a 'perfect' body shape. But with bulimia, there are periods of binging and purging. This means that the individual with bulimia may go through a period where they eat an excessive amount of food and then purge by using exercise, medications or vomiting to get rid of the food.

(I copied this from betterhelp.com)

Answer:

Anorexia disease is a disease where you eat to little and you exercise for long periods of time. They feel over weight when they are actually underweight. They weight themselves and restrict the food they eat. People with anorexia die from starvation. Bulimia disease is when people eat too much food. They do forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. They have normal weight.

Determine how many Altuves you could travel in a day if you were moving at 45.000 mph all day. Altuve = 1.65 m

Answers

Answer:

The answer is below

Explanation:

Speed is the ratio of total distance traveled to the total time taken. It is given by the formula:

Speed = Distance / time taken

Given that the speed = The polynomial 45.000 mph.

In a day there are 24 hours, hence, the distance traveled is:

Speed = Distance / time taken

45 mph = Distance / 24 hours

Distance = 45 mph × 24 h = 1080 miles

But 1 mile = 1609.34 m

1080 miles = [tex]1080\ miles*\frac{1609.34 \ m}{1\ miles}=1738092\ m[/tex]

Given that Altuve = 1.65 m

Hence, the number of Altuve traveled = 1738092 m / 1.65 m = 1053389

1053389 Altuves was traveled

An object is projected with initial speed v0 from the edge of the roof of a building that has height H. The initial velocity of the object makes an angle α0 with the horizontal. Neglect air resistance. If α0 is 90∘, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground?

Answers

Answer:

Explanation:

Initial velocity u = V₀ in upward direction so it will be negative

u = - V₀

Displacement s = H . It is downwards so it will be positive

Acceleration = g ( positive as it is also downwards )

Using the formula

v² = u² + 2 g s

v² = (- V₀ )² + 2 g H

= V₀² + 2 g H .

v = √ ( V₀² + 2 g H )

A woman drives to her office 10 km away from her house at 9 am, and
reaches her office at 9:20 am. She stays in the office until 6 p.m, and
then returns home at 6:25 p.m. Which answer gives the correct
distance and displacement at 6:25 p.m.?

Answers

The distance is 0 because she is where she started the displacement is 10km as that is the total distance away she traveled.

The displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

The given parameters;

distance between the woman's house and her office, d = 10 kmtime to reach her office = 20 minutestime to return to her house = 25 minutes

Displacement is defined as the change in the position of an object. It can be described as 'how far' an object is displaced from the initial position.

The first position of the woman, x₁ = 10 km to officeThe final position of the woman, x₂ = 10 km back home

The woman's displacement = x₂ - x₁ = 10 km - 10 km = 0

Distance is the total path covered by an object during motion.

Total distance of the woman at 6:25 pm = 10 km + 10 km = 20 km

Thus, we can conclude that the displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

Children were to be sent to designated schoolmasters for their learning.

Answers

Answer:

What was not required by the Massachusetts Education law of 1642 is;

Children were to be sent to designated schoolmaster for their learning

Explanation:

The Law of 1642 required that parents and master see to it that their children knew the principles of religion and the capital laws of the commonwealth.

The important aspects of the 1642 Law includes;

1) The responsibility for the basic education and literacy of a child are those of the parents and masters of child apprentices

2) Reading and writing competency of all children and servants are a requirement

3) It is the duty of the government, where a parent or master are unable to meet their tutoring responsibility, to see that a child is placed where the basic educational requirement will be met.

The role of a schoolmaster or the setting of a formal school were yet to be formed as at that time.

Answer:

The correct answer is Children were to be sent to designated schoolmasters for their learning

The responsibility of educating children was on parents and apprenticeship masters, not on designated teachers or schoolmasters. However, the law did allow the government to step in if the supervising adults failed in their responsibilities.

And calculate the cars displacement.

Answers

Explanation:

This problem is on the motion of a car.

given data.

acceleration a=7.55m/s

time t= 4.25 sec

1. Determine the final velocity of the car.

we know that

acceleration= velocity/time

substituting our given data we have

7.55= v/4.25

v=7.55*4.25

v=32.08m/s

2.  calculate the cars displacement.

we also know that

velocity= distance/time

distance= velocity*time

distance= 32.04*4.25

Density, describes how compact the matter is in a substance. A bowling ball is more dense than a beach ball. Color - Describes how light reflects off a substance. Luster - Describes how shiny a substance is.

Answer:

The physical properties is hardness shape and color, I choose hardness because I have grabbed bowling balls before and they are very hard well there could be different types of bowling balls made of different things but I have never seen one or toughed a bowling ball that is not hard. Another physical property  I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different  shape. That is the physical properties of a bowling ball.
