Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Variation in the factors of climate leads to variable temperature around the world.
The rate of temperature change does not stay constant over time because of changes occur in the climatic factors. The climatic factors such as latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds can't remain constant which leads to variable temperature in different regions of the world.
The temperature will remain the same if all the world has same environmental conditions so we can conclude that variation in the factors of climate leads to variable temperature around the world.

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.
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
distance= 136.37m

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.?
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 minutesDisplacement 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 homeThe 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?
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:
Answer:
The answer is
0.25 m/sExplanation:
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/sHope 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

Which of the following was not required by the Massachusetts Education Law of 1642?
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.
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
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.

What happens to the acceleration of an object if the net force on it increases?
OA. The acceleration increases.
OB.
The acceleration decreases.
O C.
The acceleration becomes zero.
OD.
The acceleration remains the same.
Answer:
A
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased
An object example to decrease pressure.
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 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
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]
