A train accelerates from rest and covers a distance of 600m in 20s. What is the train's speed at the end of 20s? What is the final velocity of the train after 20s?
Answer:
v = 60 m/s
final velocity after 20 seconds depends on how long it continues to accelerate after 20 seconds. Also we do not know the direction to complete the velocity requirements of a scalar value and direction component.
Explanation:
If we assume that the acceleration is constant
d = ½at² = ½(Δv/t)t² = ½Δvt = ½(v - 0)t = ½vt
v = 2d/t
v = 2(600)/20 = 60m/s

In order to have a good hypothesis, which of the following are needed:
Answer:
There must be a possibility to prove that the hypothesis is true. There must be a possibility to prove that the hypothesis is false. The results of the hypothesis must be reproducible.
Explanation:
Make sure your hypothesis is "testable." To prove or disprove your hypothesis, you need to be able to do an experiment and take measurements or make observations to see how two things (your variables) are related. You should also be able to repeat your experiment over and over again, if necessary
Which of the following can be excluded when evaluating the reliability of a source? (1 point)
O accuracy of data
O timeliness of information
O purpose of the author
O length of content
D. Length of content.
Reliable sources need to be accurate, they need to make sense at the time they were created and the author needs to not be biased with their writing. It does not matter how long the content is as long as it is reliable.

distinguish between basic and derived units
Answer:
Base units are defined units based on specific objects or events in the physical world. Derived units are defined by combining base units.
Base units are defined by a particular process of measuring a base quantity whereas derived units are defined as algebraic combinations of base units. For example, length is a base quantity in both SI and the English system, but the meter is a base unit in the SI system only.
Convert 4 centimeters to meters using dimensional analysis and scientific notation. Please go step by step as I am having difficulty with this subject.
Question:-
Convert 4cm to m
Solution:-
Lets do
First note down the below formula
[tex]\boxed{\sf 1m=10^{2}cm}[/tex]
Then
[tex]\boxed{\sf 1cm=10^{-2}cm}[/tex]
Now we are given 4cm
So convert
[tex]\\ \sf\longmapsto 4\times 10^{-2}m[/tex]
If we simplify to decimal
[tex]\\ \sf\longmapsto 4cm=0.04m[/tex]
Hence done .

A vehicle starts from rest and travels 50 m in 5 s. What is its acceleration?
If an object is moving with a constant velocity then according to Newton's first law:
A- it will continue with this velocity only if a net external unbalanced force acts.
B- it will change its velocity if a net unbalanced external force is applied.
С- it will continue with its velocity as external unbalanced force acts.
D- it will continue with its velocity as friction only acts if an external unbalanced force is applied.
A man walks his dog on a very straight path in a park. He can walk back and forth as slow or fast as he wants to, but he has to stay on the path. Which of the following statements is correct for an arbitrary time interval?
a. His average speed can be greater than the magnitude of his average velocity.
b. His average speed can be less than the magnitude of his average velocity.
c. Since he is walking along a straight path, his average acceleration must be zero.
d. His average velocity must be zero.
Answer:
a. His average speed can be greater than the magnitude of his average velocity.
Explanation:
As speed is distance traveled over time traveled, this is always greater than zero if he has moved at all.
velocity is displacement over time traveled. As the man is allowed to return to the point of origin, his velocity at some point might be zero while his speed is positive.
You are taking a turn at 30.0 m/s on a ramp of radius 25.0 m. What is your acceleration?
Acceleration = v^2 / r
Acceleration = 30^2/25
Acceleration = 900/25
Acceleration = 36 m/s^2
If you are given force and time, you can determine power if you can know
(a) watts
(b) energy
(c) distance
Answer:
joules/energy.
Explanation:
power is defined as the rate of work. Hence power=work/time, then you obtain Watts.
Work is the product of force and displacement.
A car is accelerating at 6 m/s2. How long would it take the car to go 12 m/s faster?
Answer:
2 seconds
Explanation:
Each second, it increases its speed by 6 m/s, so it will take 2 seconds for the speed to increase by 12 m/s.
Object X is attracted to object Y. If object Y is negatively charged, what can you say about object X? (a) It is positively charged (b) It is negatively charged (c) It is electrically neutral (d) Object X may be positively charged, but it is possible it is also electrically neutral with an induced charge separation
Answer:
a) Object X is positively charged
Explanation:
Unlike charges attract each other
Like charges repel each other
The object X will be positively charged through charging by conduction.
The given parameters:
Object Y = positively chargeA charge can be produced by conduction. This method of charge generation involves charging a neutral body by placing it in contact charged body.
When object X is placed in contact with object Y, which is negatively charged, the negative charges of object Y repels negative charges of object X. This leaves object X with excess protons, thereby becoming positively charged.
Thus, the object X will be positively charged through charging by conduction.

why do we observe winds blowing towards the equator
Answer:
The cooler air from region of up to 30degree latitude belt on both sides of the equator ,rushes toward the equator ,to take the place of warm rising air. This makes the wind to blow from north and south direction toward equators

What's kinematics? What is it concerned with?[tex] \huge \boxed{\mathfrak{Answer} \downarrow}[/tex]
Kinematics is a branch of mechanical physics that deals with motion. It includes all types of motion & all ways of showing motion (like, through graphs, moving objects & so on). In short kinematics is the => geometry of motion.A wheel of mass 4kg is pulled up a plane inclined at 30° to the horizontal by a force of 45N applied to the axle and parallel to the plane. If the wheel has a radius of 0.5m and the moment of inertia 0.5kgm?, calculate the translational velocity acquired after travelling 12m up the plane, assuming the wheel is initially at rest (6 marks)
Answer:
v = 10 m/s
Explanation:
Let's assume the wheel does not slip as it accelerates.
Energy theory is more straightforward than kinematics in my opinion.
Work done on the wheel
W = Fd = 45(12) = 540 J
Some is converted to potential energy
PE = mgh = 4(9.8)12sin30 = 235.2 J
As there is no friction mentioned, the remainder is kinetic energy
KE = 540 - 235.2 = 304.8 J
KE = ½mv² + ½Iω²
ω = v/R
KE = ½mv² + ½I(v/R)² = ½(m + I/R²)v²
v = √(2KE / (m + I/R²))
v = √(2(304.8) / (4 + 0.5/0.5²)) = √101.6
v = 10.07968...
