ANSWER:WISH i KNEW the answer

Explanation:

Answer:

12m

Explanation:

USING 1st eq. of motion, v=u+at

4m/s = 0 + a*6s

a = 4/6 m/s²

now using 2ND eq. of motion, s = UT + 1/2at²

s = 0*6+1/2(4/6*(6)²)

s=1/2(4*6)

s= 1/2*24

s= 12M. answer

Virtual

Explanation:

AT REST THE INITIAL VELOCITY OF THE BODY IS GOING TO BE ZERO

U=0M/S

A=2M/S^2

T=4S

V=?

WE KNOW THAT V EQUALS INITIAL VELOCITY PLUS PRODUCT OF ACCELERATION AND TIME

V=U+AT

V=0+2*2

V=4M/S

ANSWER:

I don't KNOW PLEASE SEARCH on GOOGLE.......

ANSWER:

EXPLANATION:

ACCELERATION is v-u/t,

v=80 km/h,

u=60 km/h,

t=5 sec,

80-60/5,

20/5,

4 ms^2 is the retardation.

ANSWER:

ENERGY,2. THERMAL energy

Answer:

3750 N

Explanation:

PRESSURE = 150 PA

Area = 25 m²

Force(N) = Pressure(Pa) x Area(m²)

              = 150 x 25 N

              = 3750 N

Hope this helps : )

ANSWER:

PRESSURE = Force/Area = 5000/20 =

250 PA.

ANSWER:

by RATING and THANKING the answer of other

Answer:

Given that,

Force applied on the OBJECT, F = 400 N

Area of cross section of the object, A=0.5\ m^2A=0.5 m

2

We need to find the pressure exerted by the object per unit area. It is given by the net force acting on the box per unit area. Its formula is given by :

P=\dfrac{F}{A}P=

A

F

P=\dfrac{400\ N}{0.5\ m^2}P=

0.5 m

2

400 N

P = 800 Pa

So, the pressure exerted by the box on the table is 800 Pa. Hence, this is the required solution.

Hyy DUDE

Pressure=Force/Area=560/1.6=350 N

5.0

OR

Given,

Force=560 N

Area=1.6 m^2

We KNOW,

Pressure=Force÷Area=560÷1.6=350 Pa

May this helps you

Rate of evaporation

There are many factors that AFFECT the evaporation rate.

EXPOSED SURFACE area (faster when increased)

, the humidity of SURROUNDINGS (slower when increased),

the presence of WIND (faster when increased)

and

the temperature (faster when increased).

Answer:

360km = 360×1000 = 360000m

time = 360000÷20m/s

= 18000s

Explanation:

because the TRAIN have to COVER a LONG DISTANCE

Explanation:

UNIFORM circular motion is accelerated because the velocity CHANGES DUE to continuous CHANGE in the direction of motion. So, even when the body moves ta a constant speed, its velocity is not constant. Thus, for a body moving in a circular PATH at a constant speed, its velocity changes continuously.

Answer:

Since there are now more particles per cubic unit of LENGTH, the DENSITY INCREASES. Also, when we increase the temperature of the gas molecules, we increase the energy of the molecules. As such, the Kinetic energy of the Molecules increase, which means the VOLUME increases. This mean the intermolecular space increases.

hope these will help you.....

please MARK as brainliest........

ANSWER:

It is given that

Frequency =3kHz=3000Hz

Wavelength =15cm=15/100 m

we know that

Velocity =Frequency into wavelength

V=2000(15/100)

V=300m/sec

Now TIME =DISTANCE /speed

Time = 2000/300m/sec

Time= 6.666sec

BHAI I KNOW what is the ANSWER

ANSWER:

OPTIONS B

Explanation:

ANGLE between FRICTIONAL force and reaction force

Answer:

Rate of CHANGE of velocity is known as acceleration with respect to TIME. So, if the PARTICLE moves with uniform velocity (i.e. its velocity is CONSTANT), the acceleration of particle is zero.

Answer:

Distance covered = 3 × pi × d = 3 × 22/7 × 21 = 198 m

Displacement = 0 [As final and initial position are same.]

Explanation:

Since sun is an object at infinity, its IMAGE will fall athe focus.

So the focal length can be taken as - 12 cm.

Let US CONSIDER the object distance as x from pole.

Since image and object distance is same, take it also as x.

According to the equation,

1/v + 1/u =1/f

1/x+1/x=1/f

2/x =1/f

So, x=f/2

Therefore, u= - 6 cm

So it should be placed 6cm INFRONT of the concave mirror.

Answer:

It is given that SUN rays converge at 12 cm.

So, focal length of the mirror = F = 12 cm. In case of a concave mirror, the size of IMAGE and object will be same if the object is placed at 2f. HENCE, in this case object must be place at 2f or 2 × 12 = 24 cm.

(c)24CM in front of the mirror is the correct answer
