Explanation:

in each 1second TRAVEL 2.5m/s,then in 2SECONDS 5m/s.

ANSWER:

PLEASE MARK me BRAINLIEST

<U>GIVEN:

• Acceleration of the car = 4 m/s²
• Initial Velocity (u) = 0 (car starts from rest)
• Time taken by the car = 2 seconds

TO FIND:

• What is the DISPLACEMENT of the car ?

SOLUTION:

Firstly, we have to find the final velocity of the car

Let the final velocity of the car be 'v' m/s

To find the final velocity of the car, we use the first EQUATION of MOTION:-

According to question:-

On putting the given values in the formula, we get

• Final velocity = v = 8 m/s

Let the displacement of the car be 'D' m

We know that the formula for finding the displacement of the car is:-

According to question:-

• Displacement = D = 16 m

❝ Hence, the displacement of the car is 16 m ❞

ANSWER:

RETARDATION is ACTUALLY (-a) and not (a).

Explanation:

Hope this helps.

HEY Pretty Stranger!

• Initial VELOCITY, u = 0.5 m/s.

• Final velocity, V = 0 m/s.

• Acceleration, a = 0.05 m/s²

★ v = u + at

→ 0 = 0.5 - 0.05 x t

→ 0.05 x t = 0.5

→ t = 0.5/0.05

→ t = 10 seconds

The body will take 10 seconds to stop.

ANSWER:

. 01666666km Or 16.66666667 METER.

Explanation:

The CAR run 1 km in 1 mins.

1 mins = 60 second.

1/60 =.01666666km

ANSWER:

REAL IMAGE,

EXPLANATION:

Answer:

I keep getting asked this question and each time I pass because there are enough correct ANSWERS already. To stop the answer requests, I will add another correct answer:

The gravity equation is: F = G m1 m2 / r^2

Double the masses (m1 & m2) and halve the distance (r):

F’ = G 2 m1 2 m2 / (r/2)^2

F’ = 4 G m1 m2 / 1/4 r^2

F’ = 16 G m1 m2 / r^2

F’= 16 F

Answer:

WEIGHT of object in water =weight of object in VACCUM - buoyant FORCE

ANSWER:

The pressure acting on the wall = N/m²

GIVEN:

• Area of tip = 2 cm²

• Area of other end = 100 cm²

• FORCE = 50 N

TO FIND:

• The pressure acting on the wall

CONVERSION:

• 1 cm² = m²

• 2 cm² = 2 × m²

• 100 cm² = 0.01 m²

FORMULA:

• PRESSURE = FORCE / AREA

EXPLANATION:

The pressure acting on the wall = 50 / 0.0002

The pressure acting on the wall = N/m²

NOTE:

• Here area of the tip is taken because the tip exerts the force on the wall.

• The force what we give on the other end will be 50/0.01 = 5000N/m²

• This is quite less than the pressure exerted on the wall.

• This is because pressure is inversely proportional to the area. Hence less area FACILITATES more pressure on the wall.

SOME MORE POINTS:

• SI UNIT OF PRESSURE = N/m² or Pa

• DIMENSIONAL FORMULA =

• UNITS AND DIMENSIONS OF STRESS, YOUNG'S MODULUS AND PRESSURE ARE THE SAME

ITS WRONG DEAR

THE ANSWER IS --THE CUTTING EDGE OF INSTRUMENT IS SHARPENED BECAUSE IT CUT EASILY

ANSWER:

1) v=u+at

19.6=5a

a=19.6/5

a=37.5

2) s=ut+1/2gt²

s=0+1/2(9.8)(5)²

s=24.5

3) v²-u²=2as

v²-(19.6)²=2(37.5)(24.5)

v=29.4 is the answer OK FRIEND

ANSWER:

your ANSWE is correct

Explanation:

1 N ≡ 1 kg·m/s²

Explanation:

The focus is now on the TECHNOLOGY originally used during the early space missions – ABLATIVE heat shields. These shields work by COVERING a LARGE ROUNDED surface with compounds that, when superheated during re-entry, burn off. This dissipates the heat as the material is burnt away.

ANSWER:

EXPLANATION:

v=at

v=10 m/s

s=ut+1/2at^2

s=-25 m

s=ut+1/2at^2

-25=10t - 5t^2

t^2-2t-5=0

t=6.9/2

t=3.45 sec

s=t^2

s=11.9025 m

Explanation:

BOOM!

ANSWER:

As water is POURED over the can, some steam in the can condenses into water, reducing the amount of AIR inside. The pressure of air inside the can decreases than the pressure exerted by the air from outside the can. As a RESULT the can gets compressed. This activity again confirms that air exerts pressure.

Explanation:

Non-renewable ENERGY comes from SOURCES that will run out or will not be replenished for THOUSANDS or even millions of years. Most sources of non-renewable energy are fossil fuels. Fossil fuels were created as the remains of marine CREATURES decayed millions of years ago, under HUGE amounts of pressure and heat.

ANSWER:

THE FORCE REQUIRED BY A BODY IS 4N

Explanation:

Mass (m) = 2kg (Given)

Initial VELOCITY (U) = 4m/s (Given)

If there is no change in velocity then u = v , then mv - mv = 0, whereas when there is a change -

Using first equation of motion - a = v-u/t

= 0-4/2

= -4/2

= -2

Force required to keep the body in same velocity is F = m x a 

Change in velocity means acceleration - 

F = m x a 

F = 2 x 2

 F = 4 N 

Thus, according to Newton's first law of motion the body will continue to be straight motion or in a state of rest until an external force is applied on it , in this case a force of 4n is required to keep body MOVING with same velocity.

• Deep in the Earth, OIL and natural gas are FORMED from organic matter from DEAD plants and animals.
• These hydrocarbons take millions of years to form under very specific pressure and TEMPERATURE CONDITIONS

Explanation:

Multiply the time by the ACCELERATION DUE to gravity to FIND the velocity when the object HITS the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
