Answer:

HII, dear don't cry i will let you KNOW.

Explanation:

yes, by using the theorem from newton's third law of motion we know that in every ACTION there is equal and opposite reaction.so here EXISTS the recoil velocity. and from second law of motion that is law of CONSERVATION of momentum;

                   m1u1 +m2u2 = m1v1 m2v2

                                                               so by applying this formula your answer got correct.(9m/s).

as you have have asked for how it came so i have given the direct answer. you didnt asked for solution because you got it right!

ok so mark me as brainliest  .

Answer:accelerated MOTION

Explanation:as u have mentioned about circular motion .due to the change in DIRECTION we can CONCLUDE that it is accelerated motion

Explanation:

In a SERIES circuit, the CURRENT is the same at each resistor. ... The voltage DROP (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. Thus the ELECTRIC potential difference across any one of the bulbs will be the same as that across any one of the other bulbs.

Answer:

Distance covered in n SECONDS is simply calculated by 2ND equation of motion…..

S(n)= UN + 1/2(a) (n^2)

Where u=0 becoz object is at rest initially so it BECOME s(n)= 1/2(a)(n^2)

#Distance covered in nth SECOND is define as distance covered from (n) to (n+1) second which comes as s(nth)= (a/2)×(2n+1).

Hence ratio will comes as (2n+1)/(n^2).

Given :

➳ MASS of CAR = 1000kg

➳ Mass of truck = 8000kg

✪ Before collision :

➳ Velocity of car = 32m/s

➳ Velocity of truck = 4m/s

✪ After collision :

➳ Velocity of car = -8m/s

(negative sign shows OPPOSITE direction.)

To Find :

➨ Velocity of truck after collision.

SoluTion :

⇒ Since, no external force acts on the whole system (car + truck), we can apply concept of momentum conservation to SOLVE this type of questions.

⇒ Momentum is defined as the product of mass and velocity.

⇒ As per law of momentum conservation,

Explanation:

MATERIALS REQUIRED:

COCONUT Shell

Bamboo stick ( length = 14 INCH, width = 3/4 inch )

Fishing line ( I used 0.35mm line here, length= around 60 inch )

TOOLS REQUIRED:

Drill Machine ( or any other tool to make large holes in the coconut shell )

Sand Paper (optional )

Cutting Blade

STEPS:

Gather the require materials, Using sand paper make the surface of coconut shell smoother. and drill a hole in the shell using Driller ( you can also use nail and hammer to cut a hole ). Here i have used driller and drilled small holes nearby to make it look like oval shape, I have also used file to make it look even. Width of drilled holes should be less than that of the bamboo stick.

Now using cutting blade scrape out sides of bamboo in the end which has to be locked into the shell, after attaching bamboo stick into the shell please make sure, bamboo does not move any further.

Cut out TWO small v groves in the coconut shell as well as other end of bamboo stick, this is done so that the string would not slip out.

Measure the length of string that has to be used, In my case it was around 52 inches and have used fishing liner of .35mm . now tie the ends of the string to make a loop and slip it into the instrument as shown in the white sheet. ( please note that the string is tight and the tightness is responsible for the tune coming out of it, so do experiment).

Explanation:

Given Two conducting spheres of RADII 2 cm and 4 cm have equal surface CHARGE density FIND the ratio of electric potential on the surface

• Now we have σ = Q / A
• Also given ratio of radii r1 : r2 = 2 : 4
•                                                     = 1 : 2
• Now we have A1 : A2 = 4πr1^2 : 4πr2^2
•                                      = r1^2 : r2^2
• So we get the ratio as A1 : A2 = 1 : 4
• Then σ1 : σ2 = Q / A1 : Q / A2
• So we get A2 : A1
•              = 4 : 1

Explanation:

Instantaneous Power delivered by a force is P=

F

.

v

As the body is moving along a STRAIGHT LINE and the force is constant, we can write P=Fv

For a constant F, acceleration a will be constant (say k).

If initially, the body is at rest, we can write velocity v=kt and P=Fkt. As F and k are CONSTANTS, graph of P vs t will be a straight line passing through origin.

So, graphs (B) can represent the PLOT of P vs t

Explanation:

• Linear motion (also called rectilinear motion) is a one-dimensional motion ALONG a STRAIGHT line, and can therefore be described MATHEMATICALLY using only one spatial dimension.

• In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. ... Since the object's velocity vector is constantly CHANGING direction, the moving object is UNDERGOING acceleration by a centripetal force in the direction of the center of rotation.

• A motion repeating itself is referred to as periodic or oscillatory motion. An object in such motion oscillates about an equilibrium position due to a restoring force or torque.

ANSWER:

H2O + CO2 + co2 = 2CO2 + h2o

Given :

M1 ,MASS of car = 1000kg

M2 , mass of TRUCK = 8000 kg

U1 , initial velocity of car = 32 m/s

U2 , initial velocity of truck = 4 m/s

V1 , final velocity of car = 8 m/s

To Find :

V2 , Final velocity of truck

Conservation Of Momentum :

Solution :

(1000 * 32) + (8000 * 4) = (1000 * – 8) + (8000 v2)

∴ 32000 + 32000 = – 8000 + 8000 v2

∴ 64000 = 8000 (v2 – 1)

∴ v2– 1 = 8

v2 = 9 m/s 

☆ THEREFORE V2 = 9m/s

Hope it HELPS uhh!

EXPLANATION:

Yes, it's very simple logic but need THREE RESISTOR COMPONENTS of 1000 ohm each.

First, connect two 1000ohm resistors in parallel, which will YIELD a net resistance of 500ohm.

Now connect the other 1000ohm resistor in series with the parallel resistors.

Now the total net resistance will be the 1500ohms ,which is your desired resistance.

We know that :

So,

Now,

We have :

Initial velocity of the body = 0 ms⁻¹

Final Velocity of the body = 12 ms⁻¹

Accelation = 2 ms⁻²

Third Step :

Use Newton's second law of motion.

Now,

We know that :

Newton's second law of motion :

ANSWER:

2500 WATTS the answer YES HA

Answer:

Radius (r) = 20 m.

Speed (v) = 36 km/hr = 10 m/s.

Coefficient of the Static Friction(u)= 0.4

tan α = v²/RG

⇒ α = tan⁻(1/2)

Therefore, SIN α = 1/√5 and Cosα = 2/√5

Using the Formula,

V max. = \sqrt{\frac{rg(Sin\alpha + uCos\alpha)}{Cos\alpha - uSin\alpha}

On Solving it,

V max. = 15 m/s. = 54 km/hr.

V min. = \sqrt{\frac{rg(Sin\alpha - uCos\alpha)}{Cos\alpha + uSin\alpha}

On Solving, V min. = 14 km/hr.

Therefore, Possible speeds of the Vehicle so that it neither SLIPS down nor skids up is 14 km/hr to 54 km/hr.

Hope it HELPS.
