How can you put this in detail? a person in a moving bus is moving compared to building and another object outside but in rest relative to the bus itself
Answer:
Its true.
Explanation:
Because if we are in bus we are not moving ,the bus is moving . And the things around which are in rest feels that we are moving. So comparative to them we are moving. But comparison to bus we are in rest because bus is moving and we are sitting inside bus .

What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the design that must be kept in mind while solving the problem. A criterion answers the question, What do you want the design to do? A constraint is something that prevents the design from performing at its best. These constraints can include time, resources, and money.
When designing the airbag, what are some criteria you might consider and what constraints would you anticipate in its implementation?
Create a list of at least two criteria and at least three constraints that you must consider in the design. Rank them in order of importance, with the most important ones at the top of the list.
Answer:
The criteria listed in order of importance are;
1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle
2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision
3) To be relatively tough so as to resist being torn on impact with a sharp object
The constraints listed in order of importance are;
1) How is the model design able to sense a collision that requires the airbag to be inflated
2) The uncertainty of the load the airbag will withstand upon collision
3) The possible hazard that could be caused by the gas used to inflate the airbag
4) The usage/interaction tendency between the vehicle occupant and the airbag system
Explanation:
In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.
The criteria that should be considered include:
To be inflated in the event of a collision.Ability to withstand the load of the braking force of the occupants.Durability.It should be noted that when designing an engineering solution, there are some criteria and constraints that must be considered in order to achieve the objective of the engineering solution.
Some of the criteria that should be considered include the fact that it should be inflated in the event of a collision, the ability to withstand the impact of the braking force of the occupants, durability, etc.
The constraints listed include how the model design is able to sense a collision that requires the airbag. The possible hazards that can be caused by the gas. Also, it's vital to consider the interaction tendency between the airbag and the occupants of the vehicle.

Which choice describes an organism found in the understory of a rainforest? Responses
A. Palms and other small trees
B. Very tall trees
C. Bacteria
D. Thick, woody vines
Answer: Palms and other small trees
Explanation:
Answer:
A. Palms and other small trees
Explanation:
Understory Layer
Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

CH4 ( + Brz (→ CH3Br (2+ HBr ( CzH4 + HBr → CzHsBr CaHs to + H2 (→ CH10 l C3H6 tes + 12 6 → CHol2 ley
Explanation:
The enthalpy change for the given following chemical equation is 204 kJ/mole.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The sum of reactant's enthalpy, C-H +O=O=413+495=908 KJ/mole and that of product is C=O +H-O=445+467=1112 KJ/mole and hence the difference is 1112-908=204 kJ/mole.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Newton's second law of motion is F = ma.
A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases?
Answer: The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
Explanation:
Force is defined as the product of object's mass and acceleration.
Mathematically,
F = ma ......(1)
or,
a = F/m .....(2)
where,
F = Force exerted on an object = 60N
m = mass of an object = 30kg
a = acceleration of the object = ?
Putting values in above equation, we get:
a = 60 kg.m/s^2/30 kg = 2m/s^2
The acceleration of the car is 2m/s^2.
From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.
And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.
Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
A net force of 60 N north acts on an object with a mass of 30 kg , so according to Newton's second law of motion the acceleration of the object would be 2 m / s²,the amount of acceleration would decrease if the mass of the object increases.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
F =m × a
As given in the problem, a net force of 60 N north acts on an object with a mass of 30 kg.
60 = 30 × acceleration
acceleration = 60 / 30
= 2 m / s²
Thus, the acceleration of the object would be 2 m / s² , and the acceleration would decrease if the mass of the object increases.
