e the mouth of the boiling tube with a rubber CORK that has two bores and clamp it with the stand. ... Introduce a THERMOMETER (temperature range -10 to 110°C) in one bore of the cork of the boiling tube. Keep the bulb of the thermometer about 3-5 cm above the SURFACE of the water.

Explanation:Solution,Here, we have,Power ONE of LENS = P₁ = + 2.5 D Power two of lens = P₂ = - 0.5 DTo FIND,Power and FOCAL length We KNOW that,Power combination = P₁ + P₂= + 2.5 + (- 0.5)= 2.5 - 0.5= 2 DHence, the power is 2 D.Now, Focal length,We know that,Power = 1/focal length⇒ 2 = 1/f⇒ 2/1 = f ⇒ f = 2 mHence, the focal length is 2 m.

Explanation:UNIFORM SPEED:when a object covers EQUAL distance in equal interval of time is CALLED uniform speed. Non - Uniform speed:when object does not covers equal distance in equal interval of time is called non- uniform speed. THANK you ⚡⚡⚡⚡

A high-PRESSURE zone forms as the cooler LAND cools the air immediately above the surface. WINDS aloft flow from the ocean to the land. Winds at the surface flow from high to low pressure, CREATING a land breeze.

F₁ = (1/√2) N and F₂ = (3/√2) NExplanation:APPLYING equilibrium conditions. : Horizantal Forces : F₁ + 1 SIN 45° - 2 sin 45° = 0⇒ F₁ = 2 sin 45° - 1 sin 45°⇒ F₁ = sin 45°⇒ F₁ = (1/√2)    ------ (1)Now,VERTICAL Forces : 2 cos 45°  + 1 cos 45° - F₂ = 0⇒ 3 cos 45° - F₂ = 0⇒ 3 cos 45° = F₂⇒ 3(1/√2) = F₂⇒ 3/√2 = F₂Therefore,F₁ = (1/√2) N and F₂ = (3/√2) NHope it HELPS!

tion:FORCE can change the direction of a moving or STILL object as SHOWN:You apply a force on a almirah to make it face in a different direction. A football player kicks a football to make it MOVE in a different direction, over to another player of his team.

tion:horizontal WORK is zero as the force is in VERTICAL DIRECTION and the motion is in horizontal direction.

Explanation:Correct Question,A BODY covers a distance of 10 m with a VELOCITY of 5 m/s and further covers a distance of 20 m with a velocity of 4 m/s. Find the AVERAGE velocity for the motion.Answer,Here, we haveDistance, D₁ = 10 mSpeed, S₁ = 5 m/sDistance, D₂ = 20 mSpeed, S₂ = 4 m/sTo Find,Average Speed.We KNOW that,Time taken = Distance/Speed⇒ Time taken in 1st case = 10/5 = 2 seconds⇒ Time taken in 2nd case = 20/4 = 5 seconds⇒ Total time taken = 2 + 5 = 7 secondsThen,⇒ Total distance covered = D₁ + D₂ = 10 + 20 = 30 mwe know that,Average velocity = total distance/total time taken⇒ Average velocity = 30/7⇒ Average velocity = 4.28 m/sHence, the average velocity of body is 4.28 m/s.

The force of frictionThe frictional force is the other COMPONENT; it is in a DIRECTION parallel to the plane of the interface between objects. ... When a frictional force exists but there is no relative motion of the SURFACES in contact (e.g., the book isn't sliding across the table), we call it a static frictional force.

546.25 JExplanation:Given: MASS(m) = 20.7 KG distance(s) = 2.69 m ACCELERATION due to GRAVITY (g) = 9.81m/s²To find: Work done = ? formula:therefore, work = mg × sSubstituting the values, work = 20.7(9.81) × 2.69 = 203.067 × 2.69 work = 546.25 N-m work = 546.25 Joules

so what????????? ??? ???

ecause of the gravitational force working on the BUCKET when you THROW the bucket in the WELL it is empty so the force of gravitation is also less as it is directly PROPORTIONAL to weight but when you pull it out the water in the bucket increases its weight which causes more gravitational force to work on the bucket HOPE IT HELPS YOU PLEASE MARK AS BRAINIESTFOLLOW ME ❤️

yes it is easier to remove fresh stains as when something is just spilt it is STILL wet and the cloth hasn't absorbed it YET, but when it is caused a few ...is easier to remove an ORBITAL electron from an atom, but quite difficult to remove a nucleon from a nucleus.

glows because it is a very big ball of gas, and a process called nuclear FUSION is TAKING place in its core. ... Hydrogen really doesn't burn, it fuses, into HELIUM. So no oxygen is required!...HOPE this HELPED....

ce between the two charges is directly proportional to the product of the charges and INVERSELY proportional to the square of the distance between them. HENCE, if distance between charges is HALVED (charges remaining kept constant), the force between the two charges is quadrupled.Høpe it will Help uh!!...XD♥️#Be BRAINLY#______________Thanks ✊

I don't KNOW about this. I am REALLY SORRY my DEAR FRIEND

In a circular motion when the BODY COMES back to the original POSITION then the displacement of the body is shortest distance between the FINAL and the initial position of object. So the displacement is zero.

Figure (a) shows DISPLACEMENT TIME GRAPH. Parthas greater slope and part. Therefore, velocity while going to MARKET is higher compared to velocity while coming back.
Figure (b) shows velocity time graph. Again velocitywhile going to market is higher than areas enclosed between time axis and velocity curves t/physics_images/PR_IX_V01_C01_S01_121_S01.png" WIDTH

The heat capacity and the specific heat are related by C=cm or c=C/m. The MASS m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the EQUATION: Q=mcΔT. Values of specific heat are dependent on the PROPERTIES and phase of a GIVEN substance.

Relaxation TIME can be defined as the time taken by electron to attain an average velocity which is 1/e times its value. The average time INTERVAL between TWO successive collisions is called relaxation time of electronsExplanation:AND MARK ME AS BRAINLIEST ANSWER PLZZZZZ

━━━━━━━━━━━━━✦ REQUIRED Answer:♦️ GiveN:The body moves 4 m East and then 3 m west.♦️ To FinD:Find DISTANCE....?Find displacement.....?━━━━━━━━━━━━━━━━━━━━✦ How to Solve?Before solving this question, we need to know the actual definitions of distance and displacement, especially their difference. The is the actual path covered by the body. The total length of the path travelled, whereas is the shortest path between the initial and final point. It doesn't depend the path covered by body, only we should consider the straight line joining the initial and final point to be the displacement. ━━━━━━━━━━━━━━━━━━━━✦ Solution: Refer to the attachment...Let the body started its journey from A, and travels 4 m east to reach B. Then it travels 3 m SOUTH to reach point C. So, the body travels from A to B, and then B to C. So, total distance travelled AB + BC.Now, we have initial point A and final point C, so we know that displacement is the shortest path between initial and final point. So, displacement will be AC.By using pythagoras theoram, ━━━━━━━━━━━━━━━━━━━━

the forces are balanced as there is no movementExplanation:Balanced forces are forces with a not force of 0Ex: when you PUSH a box against a WALL, the box doesent move as the wall provides an equal and OPPOSITE force and thus the net force is 0

Questions to ask to FIND the magnetic LINES are closed loops are: 1.Where does the magnetic flow START and end in a magnet? 2. Are the magnetic lines BROKEN anywhere between the poles?EXPLANATION:AND MARK ME AS BRAINLIEST ANSWER PLZZZ

Balanced FORCES do not CAUSE a change in motion. When balanced forces act on an object at REST, the object will not move. If you push against a WALL, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are UNBALANCED forces

u= 5 m/ s.Explanation:After 6s, it is given the final velocity is 15 m/ s.Therefore,15 = u + 6a2 × a × 60 = 15^2 - u^2120 = a^2+ 36A^2 + 12au - 2^2120 a = 36a^ + 12au120 a = 36a + 12au 10 = 3A + u15 = u + 3a + 3a15 = 10 + 3a a = 5/ 3m / 5^2Using this, we get u = 5m/ s.Hope it's help ! ...........Thank you......

This is because the pressure of the water is MUCH GREATER deeper down and the dam needs to be thick at the BOTTOM so that it is strong ENOUGH to withstand this larger pressure.
