Answer:

1.Mechanical advantage is a measure of the force amplification ACHIEVED by using a tool, mechanical device or machine system. The device TRADES off input forces against movement to obtain a desired amplification in the output force. The MODEL for this is the LAW of the lever.

2.Intermolecular forces are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions.

3.Kinetic friction, also known as dynamic friction or sliding friction, occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

4.Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

5.Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane.

6.Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. When light travels through a medium, say AIR or water, it follows a straight line. However, the path only changes in case there is a shift in the medium.

Answer:

1. Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical DEVICE or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

2.Intermolecular forces are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions

3.Kinetic friction, also known as dynamic friction or sliding friction, occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

4.A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable PROPERTY of a magnet: a force that pulls on other ferromagnetic MATERIALS, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

5.Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.

6.Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. When light travels through a medium, say air or water, it follows a straight line. However, the path only changes in CASE there is a shift in the medium.

y(x, t) = a SIN (kx + ωt + φ ), The above equation represents a transverse WAVE moving along the negative direction of the X-axis. ... Here, the PLOT shows a wave TRAVELLING in the positive X direction

AnsWer :-

• We're given that, mass (m) of the box is 10 kg and LIFTED the box from ground to height (H) of 2 meter i.e displacement (s) is 2 meter. and the force acted on the box is in the downward direction that force is KNOWN as force of gravity. We need to find the work done (W) by the coolie on the box

Let's calculate the work done by the coolie on the box by USING given below formula :

↠Work done = F × s × cos θ

• F = mg

↠Work done = mg × s × cos θ

Plug in the known values in the above formula :

↠Work done = 10 × 9.8 × 2 × cos (0°)

• cos (0°) = 1

↠Work done = 98 × 2 × 1

↠Work done = 196 J

∴ The work done (W) by the coolie on the box is 196 J.

Answer:

Diffusion is the MOVEMENT of particles down their concentration gradient, meaning they FLOW from places of high concentration to places of low concentration. When the substance diffusing is water, the process is called OSMOSIS. ... The TWO main TYPES of diffusion are passive diffusion and facilitated diffusion.

ANSWER:

Explanation:

moment of force = (200×0.5 ) Nm

                            = 100 Nm

if force is EQUAL to 80N

moment of force= 80N× X m  

            100 Nm=80x

            x= 100/80

            x = 5/4 m

if in cm = 5×100/4

             = 125 cm

Answer:

Relative DENSITY of a substance is defined as the ratio between the density of the substance to the density of water at 40C. Relative density is also known as specific gravity. The relative density of a substance is a pure number WITHOUT any unit. It TELLS how many TIMES a substance is HEAVIER than water.

Answer:

Solution: , the RUBBER gloves will save the electrician from any ELECTRIC SHOCK while REPAIRING an electric SWITCH

If you look at it an electrical wire is a bit like a hose that is used to conduct water to a point we wish to USE it. Like a sprinkler. Without the hose the water just goes where we do not want it to go and not to the sprinkler.

Copper and Aluminium are good conductors of electricity. They are relatively cheap and an abundant recourse unlike silver and gold which are better conductors of electricity but MUCH more expensive. So that is why we use them mostly as electrical conductors.

OK so we need to contain the electricity inside the wire so it goes to where we want it to go to do the work we want it to do.. Other wise it will divert to whatever conductive path it can find and we loose it or we can be harmed by it. Electricity has the i=unfortunate habit of trying to escape. If it can find an alternate path back to the other TERMINAL of the supply it will. The results can be disastrous. since we make many electrical appliances out of METAL like steel which is a conductor we need to contain the electricity in the wires so it does not leak into the metal surrounds. That would give us a shock. Not a nice thing to happen.

So we use a material called an insulator to keep the electricity inside the cable. Rubber and PLASTIC (PVC) are the most common by other materials are also used like glass, fibreglass, ceramics as well as many other materials. The type of insulation is determined by temperature and the type of environment the cable is used in.

Answer :-

GIVEN :-

• Diameter = 70 m
• Time taken to COMPLETE one round = 30 s

To Find :-

• Distance travelled
• Displacement

Solution :-

Calculating Distance travelled :-

Here, the athlete complete one round. So, distance travelled will be equal to the circumference of the circle.

• Diameter = 70 m

→ RADIUS = 70 / 2 = 35 m

Distance = 2πr

= 2 × 22 / 7 × 35

= 2 × 22 × 5

= 22 × 10

= 220

Distance travelled = 220 m

Calculating Displacement :-

Here, the athlete completes one round in 30 seconds i.e. it comes to initial position after 30 seconds. So, displacement of athlete is zero.

Displacement = 0

Answer:

COAL and petroleum are formed as a result of degradation of ancient plant life which lived millions of YEARS ago. These dead plant matter started to pile up, eventually FORMING a substance called peat. Over time, heat and PRESSURE from geological processes TRANSFORMED these materials into coal. Since these are formed from essentially fossils, they are also known as fossil fuels.

Answer:

Acceleration a = (V - U) / t

Given: Initial velocity (U) = 80 km/hr = 80 × 5/18 = 400/18 = 22.2m/sec

FINAL velocity (V) = 60 km/hr = 60 × 5/18 = 300/18 = 16.6m/sec

Acceleration a = (V - U) / t

= (16.6 - 22.2)/5

= -5.6/5

= -1.12 m/s2
