Is hookes law applicable to all materil?
Answer:
Hooke’s law can be applied to all materials which come back to original shape upon withdrawal of the load. It is applicable to all materials which follow the linearity of stress and strain in the elastic limit. Any object made of steel or aluminum or any other metals that follows the stress-strain linearity in the elastic zone uses Hooke’s law.
Explanation:
Answer:
No.
Materials which obeys Hook's law are called elastic material.
Elastic material are material which return to their original shape and size after force deforming them is removed.

Answer:
Kangaroo should be the answer.
Answer:
Kangaroo So there's your answer
Explanation:
Their numbers became so large that they destroyed crops and land, leading to soil erosion. They also negatively affected agriculture and plants by overgrazing. Not only did the rabbits wreak havoc on Australian croplands, but they also contributed to the decline of native plant and animal species.
An equal amount of a gas is held in two identical containers. The temperature of container 1 is 15°C and the temperature of container 2 is 30°C. In which container will the pressure be lowest? (Assume there is nothing else inside the containers.)
Answer:
Container 1
Explanation:
The reason why there will be less pressure in container 1 is that it's colder than container 2. You must have learned right, that a colder thing has its molecules less moving, and they don't expand, instead they actually decrease in volume? In the same way, it's applied to gas also. So that's why, because container 1 has 15C temperature, which is half less than container 2's 30C, that's why, container 1 has less pressure than Container 2.
So hence, container 1 has less pressure than container 2 because of its a lower temperature, which doesn't make the molecules expand, and move around that much.

Answer:
First Condition of Equilibrium is that it must be experiencing no acceleration or the external forces acting on the body should be zero.
Answer:
First Condition of Equilibrium :
The net force in all direction must be zero
Sum of all force = 0 or net F = 0
Explanation:
Examples :
Book lyinh on table Picture hanging on a wallA paratroper coming down with terminal velocitythe fluid speed v1=10 m/s at the large cross section A1 of diameter 8m. it flows in the narrow section of area A2 of diameter 4 m at speed V2. Calculate V2
Answer:
V1 A1 = V2 A2
V1 = 10m/s
A1 = 8m
10x8 =80
V2 =?
A2 = 4m
80 = V2 x 4
÷4
20 = V2
V2 =20m/s
Explanation:
If one halfs, the other doubles & vice versa. (Like inverse proportion or the reciprocal). That's why when you half 8m, the velocity doubles, on the other side. Then, balances out.

1. A rock of granite has a mass of 50 kg. if it’s weight in water
W2 = 380 N [ density = 1000 kg/m3] Calculate FB and the volume of the rock.[g =10 m/s2]
Answer:
The first part of the question is asking about BUOYANT FORCE or UPTHRUST.
Upthrust =TRUE WEIGHT-APPARENT WEIGHT
TRUE WEIGHT=mg
TRUE weight=50kg×10m/s²
=500N
upthrust=500N-380N
FB=120N
volume of the rock=mass/density.
since the granite is completely submerged, the volume of the displaced liquid will be equal to the volume of the body.
upthrust=Vdg
120N=V×1000kg/m³×10m/s²
120N=V×10000kg/m²s²
120/10000=V
v=0.012m³

Consider the electric field lines drawn below for a configuration of two charges. Several locations are labeled on the diagram. Rank these locations in order of the electric field strength - from smallest to largest.
Helppp
Answer:
The magnitude or strength of an electric field in the space surrounding a source charge is related directly to the quantity of charge on the source charge and inversely to the distance from the source charge. The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge.
Explanation:
I really hope this helps you!
The rank for the strength of electric field can be given as D>B>E>C>A. The amplitude or intensity of such an electric field inside the region around a source charge is proportional to the amount of charge.
What is electric field lines?Electric field lines are a paper representation of electric field lines. These are drawings that employ lines and arrows to illustrate electric fields surrounding charged objects, making them highly useful in understanding field intensity and direction.
The amplitude or intensity of such an electric field inside the region around a source charge is proportional to the amount of charge just on source charge as well as inversely proportional to the distance first from source charge. The rank for the strength of electric field can be given as D>B>E>C>A.
Therefore, the rank for the strength of electric field can be given as D>B>E>C>A.

Which line shows the object is moving at its fastest rate of speed?
Answer:
Line C
Explanation:
Hi there!
Speed is equal to Distance divided by Time:
speed = distance / time
Notice how distance is the dependent value on the graph, lying on the y-axis, and time is the independent value on the graph, lying on the x-axis.
The slope of a line is equal to Rise divided by Run:
slope = rise / run
"Rise" means the number of units the line travels up in the y-direction and "run" means the number of units the line travels to the right in the x-direction.
This makes the "rise" of the line equivalent to the distance, and the "run" of the line equivalent to time.
Therefore, speed = slope.
To find the line that shows the object moving at its fastest speed, we must find the line with the greatest slope (or the steepest going up).
That would be line C.

Let there be light! At the flick of a switch, a light bulb can light or illuminate an entire room, but what else is happening? One the basic laws of physics, the conservation of energy, tells us that energy is neither created nor destroyed: rather, it can only be transformed from one form to another. In the case of the light bulb, electrical energy is being transformed into light and thermal (heat) energy. Different wattages and types of bulbs give off varying amounts of light and heat. In this light bulb science project, we'll be working with incandescent and compact fluorescent lamp bulbs (CFL’s).
A person walks up a stalled 10 m long escalator in 94 s. When standing on the same escalator, now moving, the person is carried up in 60 s. How much time would it take that person to walk up the moving escalator?
Answer:
V1 = S / t1 = speed up stalled escalator = 10/94 = .106 m/s
V2 = S / t2 = speed of escalator = 10 / 60 = .167 m/s
V = V1 + V2 combined speed
T = S / V = 1 / t1 + 1 / t2 = t1 * t2 / (t1 + t2)
T = 60 * 94 / (60 + 94) = 36.6 sec
Check: combined speed = .106 + .167 = .273 m/s
T = 10 / .273 = 36.6

An engineer is designing a runway. She knows that a plane, starting at rest, needs to reach a speed of 180mph at take-off. If the plane can reach this take-off speed in 65.0s, how far will the plane travel before take-off. Assume the plane increases speed steadily.
How far does the plane need to travel during take-off (in given units)?
ft
Could the plane take off on a 10000ft long runway?
Answer:
The plane would need to travel at least [tex]8,\!580\; {\rm ft}[/tex] ([tex]8.58 \times 10^{3}\; {\rm ft}[/tex].)
The [tex]10,\!000\; {\rm ft}[/tex] runway should be sufficient.
Explanation:
Convert unit of the the take-off velocity of this plane to [tex]\rm ft\cdot s^{-1}[/tex]:
[tex]\begin{aligned}v &= 180\; {\rm mph} \\ &= 180\; {\rm mi \cdot hrs^{-1}} \times \frac{1\; {\rm hrs}}{3600\; {\rm s}} \times \frac{5280\; {\rm ft}}{1\; {\rm mi}} \\ &= 264\; {\rm ft \cdot s^{-1}}\end{aligned}[/tex].
Initial velocity of the plane: [tex]u = 0\; {\rm ft \cdot s^{-1}}[/tex].
Take-off velocity of the plane [tex]v =264\; {\rm ft\cdot s^{-1}}[/tex].
Let [tex]x[/tex] denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation [tex]x = ((u + v) / 2) \, t[/tex].
Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration [tex]t[/tex] times average velocity [tex](u + v) / 2[/tex].
The distance that the plane need to cover would be:
[tex]\begin{aligned}x &= \left(\frac{u + v}{2}\right)\, t \\ &= \frac{0\; {\rm ft \cdot s^{-1}} + 264\; {\rm ft \cdot s^{-1}}}{2} \times 65.0\; {\rm s} \\ &= 8.58\times 10^{3}\; {\rm ft}\end{aligned}[/tex].
