A force of 200N is creating a pressure of 50Pa on a surface. Calculate the area of the surface.

Answers

Answer:

4kg

Explanation:

pressure=50pa

force=200N

Area=?

now,

pressure=force/area

50=200/area

area=200/50

area=4kg

The pressure is the forces acting on a given area. Hence, the area of the surface with a pressure of 50 Pa by a force of 200 N is 4 m².

What is force?

Force is an external agent acting on a object to deform it or to change its state form motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction. The unit of force is Newton (N).

Pressure is the force applied on unit area. Thus, as the force increases, pressure increases. Pressure can have the units in atm, pa, N/m² etc.

Pressure = Force / area.

Given that force = 200 N

pressure = 50 Pa = 50 N/m²

Therefore, area =  force/pressure

                          = 200 N / 50 Pa

                          = 4 m²

Therefore, the area of the surface is 4 m².

A car accelerates from rest at 7.55 m/s2 for 4.25 s.
Determine the final velocity of the car.
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

O
Children were to be educated in basic religious principles and the laws of the commonwealth.
O Children were to be able to read and write.
O Children of servants were included in the law as recipients of said education.
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.

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.

An object example to decrease pressure.

Answers

Answer:

To reduce pressure - decrease the force or increase the area the force acts on. If you were standing on a frozen lake and the ice started to crack you could lie down to increase the area in contact with the ice. The same force (your weight) would apply, spread over a larger area, so the pressure would reduce.

Answer:

You can use the following things

Explanation:

Rubber ball - A rubber ball can decrease pressure if you throw it against the wall and catch it.

Rubber squeezy toy - If you squeeze this in your hands also you can decrease pressure.

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.

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 )

Find the velocity of a ball traveling 5 meters for 20 seconds.
Formula:
Substitute:
Solution:

Answers

Answer:

The answer is

0.25 m/s

Explanation:

The velocity of w given body given the distance and time taken can be found by using the formula

[tex]velocity = \frac{distance}{time} \\ [/tex]

From the question

distance = 5 m

time = 20 s

The velocity of the ball is

[tex]velocity = \frac{5}{20} = \frac{1}{4} \\ [/tex]

We have the final answer as

0.25 m/s

Hope this helps you

Formula: v = d/t

v = velocity

d = distance

t = time

We are given the distance (5 meters) and the time (20 seconds). Solve with these given values.

v = 5/20

v = 1/4 m/s

A 95kg clock initially at rest on a horizontal floor requires a 560N horizontal force to set it in motion. After the clock is in motion, in horizontal force of 650N

Answers

Complete Question

A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.

Answer:

The value for static friction is [tex]\mu_s = 0.60[/tex]

The value for static friction is [tex]\mu_k = 0.70[/tex]

Explanation:

From the question we are told that

The mass of the clock is [tex]m = 95 \ kg[/tex]

The first horizontal force is [tex]F _s = 560 \ N[/tex]

    The second horizontal force is    [tex]F _k  =  650  \  N[/tex]

Generally the static frictional force is equal to the first  horizontal force

So

     [tex]F _s  =  m  *  g  *  \mu_s[/tex]

=>   [tex]560  =  95  *  9.8  *  \mu_s[/tex]

=>    [tex]\mu_s =  0.60[/tex]

Generally the kinetic frictional force is equal to the second horizontal force

So

      [tex]F _k  =  m  *  g  *  \mu_k[/tex]

      [tex]650 =  95  *  9.8  *  \mu_k[/tex]

     [tex]\mu_k =  0.70[/tex]
