How would u define energy
Energy is being produced in two different ways.
1st. when you run, exercise, etc allot of energy is being produced from your body in form of heat.
2nd. energy which is in form of coal, electricity, gas etc.
Definition: the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

Elena Walks at a speed of 1.4m s^-1How long will it take her to travel 500mhow far will she travel if she walks for 2 hours? give your answer in units of km.
[tex]\bold{\huge{\pink{\underline{ Solution }}}}[/tex]
Given :-Elena walks at a speed of 1.4m/sTo Find :-We have to find the time taken by Elena to cover a distance of 500 mAnd, The distance covered by Elena in 2 hoursConcept Used :-
Here, we will use the concept of speed, distance and time
Speed is the distance per unit time Distance is measurement of length between two or more point of reference Time is the distance by speed Let's Begin :-We have given two conditions here
How long it will take Elena to cover distance of 500 mHow far she travels if she walks for 2 hours Condition 1 :-We know that,
[tex]\bold{\pink{ Speed = }}{\bold{\pink{\dfrac{ Distance }{Time}}}}[/tex]
Speed = 1.4m/sDistance = 500 mSubsitute the required values in the above formula :-
[tex]\sf{1.4 = }{\sf{\dfrac{ 500 }{t}}}[/tex]
[tex]\sf{ t = }{\sf{\dfrac{ 500 }{1 .4}}}[/tex]
[tex]\sf{ t = }{\sf{\dfrac{ 500 }{1.4}}}[/tex]
[tex]\bold{\boxed{\red{ t = 357.14 \:sec }}}[/tex]
Hence, Time taken by Elena to cover distance of 500 m is 357.14 sec
Condition 2 :-We know that,
[tex]\bold{\pink{ Speed = }}{\bold{\pink{\dfrac{ Distance }{Time}}}}[/tex]
Speed = 1.4m/s or 5.04km/h[ Speed = 1.4 * 60 × 60/1000
Speed = 1.4 × 18/5 = 5.04 km/h }
Time = 2 hoursSubsitute the required values in the above formula :-
[tex]\sf{ 5.04 = }{\sf{\dfrac{ S(Distance)}{2}}}[/tex]
[tex]\sf{ S = 5.04 }{\sf{\times{ 2}}}[/tex]
[tex]\bold{\tt{\boxed{\red{ S = 10.08 km }}}}[/tex]
Hence, The distance covered by Elena in 2 hours is 10.08 km.
WHICH ONE IS CORRECT???
Answer:
A
Explanation:
Answer:
According to Pascals law, THE PRESSURE EXERTED TO A CONFINED LIQUID IS TRANSMITTED EQUALLY AND UNDIMINISHED IN ALL DIRECTIONS THROUGHOUT THE MASS OF THE LIQUID--Blaise Pascal
so the pressure at A2 must be equal to A1
buy however the F1 will be less than F2 since:
P1=F1/A1 and P2=F2/F1
P1=P2 according to Pascal
so, F1/A1=F2/A2
with less amount of force at P1 THE force gets multiplied.
Therefore it's obvious that option A and B is wrong. I can't see option C properly.
but, you are going to have this option.
C.F1>F2
so the option with F1>F2 is correct

An object is dropped from a tower 128 m high. a. What is the speed of the object that falls freely from rest for a distance of 128 m?
The speed of the object falling freely from rest for the given distance is 50.09m/s.
Given the data in the question:
Hight of tower; [tex]h = 128m[/tex]Since object is initially at rest, initial velocity; [tex]u = 0[/tex]Free Fall Motion
A free fall is simply any motion of a body where gravity is the sole influence.
From the third equation of motion;
[tex]v^2 = u^2 + 2gh[/tex]
Where v is final velocity, u is initial velocity, h is height and g is acceleration due to gravity ( [tex]g = 9.8m/s^2[/tex] ).
To determine the speed of the falling object, we input our values into the expression.
[tex]v^2 = u^2 + 2gh\\\\v^2 = (0)^2 + [ 2 * 9.8m/s^2 * 128m ]\\\\v^2 = 2 * 9.8m/s^2 * 128m\\\\v^2 = 2508.8m^2/s^2\\\\v = \sqrt{2508.8m^2/s^2} \\\\v = 50.09m/s[/tex]
Therefore, the speed of the object falling freely from rest for the given distance is 50.09m/s.

Oo. 22 m/s2
2022 huminate Education
PLS HELP HELO ME!!!
Answer:
B) 4 m/s²
Explanation:
Since the surface it's kept on is frictionless, the net external force acting on the block will be 220 N.Mass of the block = 55 kg[tex] \boxed{ \sf{ F= m \times a}}[/tex]
Here,
F is the net external force applied to an object,m is the mass of that object, anda is the acceleration it acquires.Substituting the respective values for F and m:
==> 220 = 55 × a
==> 220 = 55 × a
dividing the equation by 55:
==> 4 = a
Therefore, an object of 55 kg when pulled across a frictionless surface by a force of 220 N accelerates at 4 (m/s)/s
The Magnetic Field in a current carrying wire comes due to flow of electricity . But does the field generate or comes in simulataniously with the flow. if simulataniously then how?
Answer:
Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. ... Magnetic Field Generated by Current: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire.

The energy of an electromagnetic wave is related to its amplitude.
Answer:
True
Explanation:
The energy carried by a wave is proportional to its amplitude squared. The larger the strength of the electric and magnetic fields, the more work they can do and the greater the energy the electromagnetic wave carries. A wave's energy is proportional to its amplitude squared (E2 or B2).
Which of the following is an example of a behavioral adaptation?
Answer:
b. migration
A migration can be defined as the changes that occur in the behavior, structure, physiology of the organism so as to allow it to survive in unfavorable environmental conditions. Behavioral adaptation can be defined as the changes that occur in an organism's behavior which affects it's actions and helps it to survive like choice of mating partner, calling the mates for copulation and migration to different location all are the examples of the behavioral adaptations
Explanation: Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

the temperature changes.
Response:
The thermal capacity of the calorimeter is 100.416 J·K⁻¹What the thermal capacity and how can it be calculated?Mass of the vessel. m₁ = 200 gram
Temperature of the water, T₁ = 24°C
Mass of the warm water, m₂ = 112 grams
Temperature of the warm water, T₂ = 42°C
Resultant temperature of the water, T₃ = 30°C
The heat capacity of the water = 4.184 J·Kg⁻¹·K⁻¹
