A bus traveling at 25.2mi/h speeds up at a constant rate of 9.2x10^-3 m/s^2. What velocity does it reach 25min later?
Answer: actually to solve this u must know what 3.2m/s2 is..do u know it ??...wel let me tell...3.2m/s2 means that in every second the speed of the body increases by 3.2m/s..so if it acts for 6.8 seconds..increase in speed will be 3.2*6.8 however note that this is the increase in speed.. have to change this in km/hr & add this to the initial speed(27km/hr) to get the answer....hope this has cleared ur doubts....

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

A group of friends are doing some archery.
When Brian fully stretches the bow, it stores 10 J of energy.
Describe the energy transfer that occurs as Brian stretches the bow.
[2 marks]
Answer: potential to kinetic/mechanical
Explanation:
When Brian fully stretches the bow, it stores 10 J of energy. The energy transfer that occurs as Brian stretches the bow will be from the potential energy to the kinetic energy.
What is the law of conservation of energy?According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
In the above problem, the potential energy gets converted into kinetic energy at the expense of the loss of gravitational potential energy between the two positions.
Friends are practicing archery together. The bow holds 10 J of energy when Brian stretches it to its maximum length. As Brian extends the bow, energy will go from the potential energy to the kinetic energy.

A car travels 15m east, then 5 m north, then 15m west. What is the car's
displacement?
Answer:
5m northExplanation:
The displacement of an object is its deviation from it initial position.
given that the initial position is
15m east and it moves 5m north
then 15m west
displacement is = 15+5-15
displacement is= 5m north

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.

B. Dress in several layers instead of wearing one bulky garment for warmth.
C. Drink hot tea during your workout.
D. Wear a synthetic or wool hat.
I NEED HELP ASAP FIRST ANSWER GETS BRAINLIEST
Answer:
D.
Explanation:
I think its D. because Tea during a cold workout isnt safe at all. Drinking tea while working out adds weight and you just simply dont need tea when working out.. Hope this helps man :)
C. You shouldn't exercise while drinking hot tea because you can spill it and burn yourself especially while on a treadmill.

The density of water is 1.00 g/mL. This means if a rock has a density of 0.87 g/mL, it will ____in water.
a) float
b) sink
Answer:
Float
Explanation:
It is given that,
The density of water is 1 g/mL
The density of a rock is 0.87 g/mL
It can be seen that the density of water is more than that of rock. The density of an object is calculated from its mass and volume.
If the density of liquid in which it is placed, is more that that of the object, it will float at the top.
Hence, in this case the rock will float.

Explanation:
just did it
The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.
What is prototype?Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.
It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.
It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.
There are three basic rule of prototyping.
Inquire as to who will gain.Fail frequently and early.Use show and ask instead of show and tell.When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.
Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

For writing a scientific lab report, when you write the discussion do you need to include every single result in your data? Or do you just include a summary of your data?
Answer:
include a summary of data
Explanation:
In writing a scientific laboratory report, only the summary of the data is included in the discussion and not the entire result.
The discussion section of a lab report deals with the interpretation and explanation of findings during the course of the experiment in relation to the background information leading to the experiment/research. Hence, only the summary of the data generated is required. The detailed results are usually reported in the result section, not the discussion section.

An object of mass 30 kg is in free fall in a vacuum where there is no air resistance. Determine the acceleration of the object. F= ?
Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .

a woman drops a rock from a bridge to the water 17.5 m below. with what speed does the rock strike the water?
a. 0 m/s
b. 18.5 m/s
c. 171m/s
d. 9.8 m/s
e. 17.5 m/s
Given :
Height from which rock is dropped, h = 17.5 m.
Initial velocity, u = 0 m/s.
To Find :
Speed does the rock strike the water.
Solution :
We know, by equation of motion :
[tex]v^2-u^2=2as[/tex] ......( 1 )
Here , a = g = 9.8 m/s² ( Acceleration due to gravity )
Putting all given values in 1 , we get :
[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]
Therefore, speed with rock strike the water is 18.5 m/s.
Hence, this is the required solution.
