A bus travels 4 km due north and then 3 km due west goingfrom bus station A to bus station B. The magnitude of the bus'
displacement from station A to station B is __km
Answers
Here, we are required to find the magnitude of the bus
displacement from station A to station B.
The magnitude of the bus
displacement from station A to station B is 5km.
The magnitude of the displacement is the "distance between the starting position of a body or object and the end position of that body or object".
The bus moves 4kmnorth and then moves 3km west, forming a right triangle. Its displacement is therefore the length of the hypotenuse.
let
x = length of the hypotenuse.
x² = 3² + 4²
x² = 9 + 16
x² = 25
Then remove the square on x by adding square roots to both sides
√x² = √25
x = √25
x = 5
The magnitude of the bus's displacement from station A to station B is 5 km.

The horizontal component of the velocity remains constant in a trajectory course.
Answer: A
Explanation:
The trajectory path is formed due to the gravitational pull acting on the object thrown from some point either upward or downward.
As it is known that the velocity is divided into horizontal and vertical component, the vertical component of the velocity of the object thrown will be mainly influenced by the gravitational pull as it acting in vertical direction only.
So the vertical component of the object following a trajectory path will be changing at a rate of 9.8 m/s2 which is the acceleration due to gravity.
On the other hand, the horizontal component of the velocity will remain constant in order to maintain the law of conservation of energy.

Answer:
chemical change through chemical process .
physical change means change in dimension.
Final answer:
A chemical change involves a change in the substance's composition, creating new substances with different properties, typically through reactions such as rusting or combustion. In contrast, a physical change alters a substance's form without affecting its composition, as in melting or condensation processes. The processes can also be classified as exothermic (releasing heat) or endothermic (absorbing heat).
Explanation:
The difference between a chemical change and a physical change pertains to the composition of the substance in question. A chemical change always results in the production of a new substance with different properties from the original matter. For example, the formation of rust from iron, or the combustion process in burning, are chemical changes. These result in the creation of substances distinct from the original matter.
On the other hand, physical changes do not affect the composition of the substance, but alter its state or form, such as the melting of ice into water or the condensation of steam into liquid water. These changes, while observable, do not produce new substances, hence maintaining the original properties of the matter.
Physical and chemical changes can also be differentiated based on whether they release or absorb heat, with exothermic processes releasing heat and endothermic processes absorbing heat. For example, the burning of a fuel is an exothermic process, while the operation of a cold pack is an endothermic process.

'Frequency' is a word that often confuses some people ... for no good reason.
It just means "frequent-ness" or "often-ness" ... how often something happens.
The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.
So " 13 Hz " means 13 per second.
Here are examples of frequency:
-- 780 kilohertz (on your AM radio dial)
-- 98.7 Megahertz (on your FM dial)
-- 5.8 Gigahertz
-- twice a day
-- three per week
-- every 6 months

Answer:
The rate at which work is done is called Power.
Explanation:
Power is work done per unit time. or it can also be defined as ratio of work done to time taken to complete the work.
Mathematically the power (P) is given as:
1 watt = 1 Joule/second
Where:
W = Work done in time T.
T = Time taken to complete the work
The rate at which work is done is called Power.
