ANSWER:

answer is ZERO answer is zero

Answer:

1- Plants and crops GROW BETTER in definite ph range, e.g., sugarcane requires neutral range of ph in soil, RICE grows better in slightly acidic ph range whereas citrus fruits require alkaline ph range of soil.

2- It helps in digestion of our food. Digestion of our food occurs at narrow range of ph. Our stomach has acidic ph range wheres intestine WORKS in alkaline ph range.

3- Selection of medicine is based on different ph range of body parts, e.g., asprin(acidic in nature) effective in intestine (alkaline ph) whereas milk of amnesia (alkaline) is effective to control INCREASED acidic nature of stomach.

4- Many other process takes place on in definite ph range:

a- qualitative analysis of mixture, e.g., removal of phosphate.

b- quantitative analysis of estimations.

c- preservation if foods and fruits

d- agriculture and dairy products manufacture.

ANSWER:

By USING Purit ultar RO

we use the third EQUATION h=ut+1/2gt^2

u=0 m/s

g=10 m/s^2

t=2 sec

h=?

h=ut+1/2at^2

or, h=0×2+1/2×10×2×2

or, h=0+5×4

or, h=20 m

so, the height of the TOWER is 20 m

Mark me as Brainliest.

Answer:

1.39 m/s²

Explanation:

Acceleration = Change in velocity / Time taken

= [(60 - 50) × 5/18 m/s] / (2 s)

= 1.39 m/s²

[NOTE: I’ve multiplied speed with 5/18 in ORDER to convert it from KMPH to m/s]

Answer:

88 MC

Explanation:

Current-charge RELATIONSHIP is

Q = it

= 22 mA × 4 s

= 22 × 10^-3 A × 4 s

= 88 × 10^-3 As

= 88 × 10^-3 C

= 88 mC

Explanation:

The motion of the arrow is a projectile motion. Then the motion of the arrow ALONG horizontal direction is a motion with constant velocity:

x(t)=VxT

Where the initial position is 0 and Vx=30*cos(20degree)=28.2m/s . Then

x(t)=28.2t

Motion along vertical axis is a motion with constant ACCELERATION, then

y(t)=VyT-gt^2/2

Where g=9.8m/s^2 , initial position is 0, and vy=30*sin(20degree)=10.3 m/s . Then

y(t)=10.3t-4.9t^2

Then we need to find the time when the arrow will be exactly above the ASSISTANT. At this moment of time x(t) =100. Then we can find the time:

t=Tarrow=30/28.2=1.06s

Then we can find the height of the arrow at this moment of time:

y(t=1.06)=1.06*1.03-4.3*1.06^2=5.4m

The assistant should through the apple with MINIMAL velocity so it will REACH point 5.4 m and at this height the velocity should be 0. From this condition we can find the minimal velocity:=10.3m/s

The time of the motion of the apple to this point is=1.05s

Then the apple should be thrown after=.01s

ANSWER:

what we should FIND sister whether FORCE any other you not even GAVE any information please write the QUESTION properly

ANSWER:

M1 = F/12

2) M2 = F/3.8

Combining, m2/m1 = 3.1578

Ergo, m2-m1 = m1*(3.1578- 1) = 2.1578m1

a(2-1) = 12/2.1578 = 5.56 m/s²

a(2+1) = 12/(3.1578+1) = 2.886 m/s²

Answer:

4/3

Explanation:

SEE the image attached

Refractive INDEX = Real depth / APPARENT depth

= 20 cm / 15 cm

= 4/3

Answer:

-1.11 m/s²

Explanation:

ACCELERATION = Change in velocity / Time taken

= [(60 - 80) × 5/18 m/s)] / 5 s

= -1.11 m/s²

Negative sign INDICATES that SPEED is DECREASED from 80 kmph to 60 kmph in 5 SECONDS

DEAR STUDENT,

◆ Answer -

W = 1866 J

◆ Explanation -

In adiabatic process,

(V1/V2)^(γ-1) = T2/T1

Here, V2 = V1/2, T1 = 273 K, γ = 1.41,

(2V1/V1)^(1.41-1) = T2/293

T2 = 2^0.41 × 273

T2 = 1.329 × 273

T2 = 362.8 K

Work DONE by expansion of gas in adiatic process is -

W = nfR∆T/2

W = 1 × 5 × 8.314 × (362.8-273) / 2

W = 1866 J

Therefore, work done on gas is 1866 J.

Thanks dear...

Answer:

20 s

Explanation:

Along vertical direction

Initial velocity of bomb = 0 m/s

Height from which it is dropped = 1960 m

Then, from equation of MOTION, s = UT + 0.5at²

1960 m = (0 m/s × t) + (0.5 × 9.8 m/s² × t²)

t² = 1960 m / (4.9 m/s²)

t = sqrt(1960/4.9) s

t = sqrt(400) s

t = 20 s

EXPLANATION:

U can do it by folding the CIRCUIT..... means join equipotential points

by overlapping just 3 RESISTANCES will be left of RESISTANCE R/2

equivalent resistance = R/3

Newton's law of universal gravitation STATES that every PARTICLE attracts every other particle in the universe with a force which is directly PROPORTIONAL to the product of their masses and inversely proportional to the SQUARE of the distance between their centers.

Dear Student,

◆ Answer - (1)

W = -2768 J

● Explanation -

In adiabatic process,

(V1/V2)^(γ-1) = T2/T1

Here, V1 = V, V2 = 2V, T1 = 27 °C = 300 K, γ = 5/3,

(V/2V)^(5/3-1) = T2/300

T2 = (1/2)^(2/3) × 300

T2 = 0.63 × 300

T2 = 189 K

Work DONE by expansion of gas in adiatic process is -

W = nfR∆T/2

W = 2 × 3 × 8.314 × (189-300) / 2

W = -2768 J

Hope this helps you...

Answer:

c/2

Explanation:

as it is given that the sound of the jet makes 60 degree with horizontal from east to WEST,

make a right angled triangle with 30 60 and 90 degree.

this represents the VELOCITY VECTORS

now the hypotenuse of this triangle will be the velocity of sound 'c'.

as we KNOW costheta= adajacent(I.e the horizontal component of the triangle)/hypotenuse

so cos60=jet speed/c

so 0.5c=jet speed

the horizontal component of the vector triangle is jet speed.

Answer:

0.98

Explanation:

F MAX=force applied*coefficient of friction

=5*0.5

=2.5

here f max is GREATER than mg

so we CONSIDER mg as friction since static friction is self adjusting

mg=0.1*9.8

=0.98
