5.	A piece of stone came to rest after covering a distanceof 20 m over an icy surface. If the initial velocity of thestone was lm.s-1, what was the coefficient of frictionbetween the stone and ice?[0.0026]
Answer» Answer: A piece of stone, moving with an initial VELOCITY of 11 m/s on an icy surface, comes to rest after covering a DISTANCE of 2020 m. We want to determine the coefficient of friction between the stone and ice. The initial velocity, uu, final velocity, vv, and distance covered, s,s, are 11 m/s, 00 m/s and 2020 m, respectively. v2=u2+2as,v2=u2+2as, where AA is the acceleration. ⇒02=12+2a×20⇒a=−140⇒02=12+2a×20⇒a=−140 m/s2.2. ⇒⇒ The magnitude of the force on the stone causing it to slow down and finally come to a stop is ma=m40ma=m40 N, where mm is the mass of the stone. The force slowing down the stone is due to friction and is equal to μN,μN, where μμ and NN are the coefficient of KINETIC friction and the normal reaction, respectively. The normal reaction, N=mg,N=mg, where gg is the acceleration due to gravity, which can be taken as 9.819.81 m/s22. ⇒μmg=\|ma\|⇒μ=

Answer»

Answer:

A piece of stone, moving with an initial VELOCITY of 11 m/s on an icy surface, comes to rest after covering a DISTANCE of 2020 m. We want to determine the coefficient of friction between the stone and ice.

The initial velocity, uu, final velocity, vv, and distance covered, s,s, are 11 m/s, 00 m/s and 2020 m, respectively.

v2=u2+2as,v2=u2+2as, where AA is the acceleration.

⇒02=12+2a×20⇒a=−140⇒02=12+2a×20⇒a=−140 m/s2.2.

⇒⇒ The magnitude of the force on the stone causing it to slow down and finally come to a stop is ma=m40ma=m40 N, where mm is the mass of the stone.

The force slowing down the stone is due to friction and is equal to μN,μN, where μμ and NN are the coefficient of KINETIC friction and the normal reaction, respectively.

The normal reaction, N=mg,N=mg, where gg is the acceleration due to gravity, which can be taken as 9.819.81 m/s22.

If (x+10)% of240 is 70% more than x%of 180% ,then 15% of (x+20)% is what percent less than 25% of x?

Answer»

Answer:

16%

Step-by-step explanation:

If (x+10) % of 240 is 60% more than x% of 180, then 15% of (x + 20) is what percent less than 25% of x?

GIVEN, 240×(x+10)%=180×x%+(180×x%)60%Given, 240×(x+10)%=180×x%+(180×x%)60%

240×(x+10)%=180×x%(1+60%)240×(x+10)%=180×x%(1+60%)

240×(x%+10%)=180x%(160%)240×(x%+10%)=180x%(160%)

240x%+24=(180x%)160%240x%+24=(180x%)160%

240x%+24=288x%240x%+24=288x%

48x%=2448x%=24

x%=2448=0.5=50%x%=2448=0.5=50%

Check, 240(50+10)%=180×50%+(180×50%)60%Check, 240(50+10)%=180×50%+(180×50%)60%

144=144144=144

Next, (x+20)15%=(50+20)15%=70×15%=10.5Next, (x+20)15%=(50+20)15%=70×15%=10.5

25%x=12.525%x=12.5

less % is 100%−10.512.5=100%−10.5×812.5×8100%−84%=16%

42.	Explain communicative prop under integer 1 ex
Answer» Answer: Step-by-step explanation: Commutative Property The commutative property of addition and multiplication states that the order of terms doesn’t matter, the result will be the same. WHETHER it is addition or multiplication, swapping of terms will not change the sum or PRODUCT. Suppose, x and y are any two INTEGERS, then ⇒ x + y = y + x ⇒ x × y = y × x Example 4: 4 + (−6) = −2 = (−6) + 4; 10 × (−3) = −30 = (−3) × 10 But, subtraction (x − y ≠ y − x) and division (x ÷ y ≠ y ÷ x) are not commutative for integers and whole numbers. Example 5: 4 − (−6) = 10 ; (−6) – 4 = −10 ⇒ 4 − (−6) ≠ (−6) – 4 Ex: 10 ÷ 2 = 5 ; 2 ÷ 10 = 1/5 ⇒ 10 ÷ 2 ≠ 2 ÷ 10

Explain communicative prop under integer 1 ex

Answer»

Answer:

Step-by-step explanation:

Commutative Property

The commutative property of addition and multiplication states that the order of terms doesn’t matter, the result will be the same. WHETHER it is addition or multiplication, swapping of terms will not change the sum or PRODUCT. Suppose, x and y are any two INTEGERS, then

⇒ x + y = y + x

⇒ x × y = y × x

Example 4: 4 + (−6) = −2 = (−6) + 4;

10 × (−3) = −30 = (−3) × 10

But, subtraction (x − y ≠ y − x) and division (x ÷ y ≠ y ÷ x) are not commutative for integers and whole numbers.

Example 5: 4 − (−6) = 10 ; (−6) – 4 = −10

⇒ 4 − (−6) ≠ (−6) – 4

Ex: 10 ÷ 2 = 5 ; 2 ÷ 10 = 1/5

⇒ 10 ÷ 2 ≠ 2 ÷ 10

Answer:

L. H. S=4z+1

R. H. S=7

Step-by-step explanation:

4z+1=7

L. H. S means left hand SIDE. So, 4z+1 is on left side. Hence, L. H. S =4z+1.

R. H. S means right hand side. So, 7 is on right side. Hence, R. H. S=7

Cosec A =√10 find all the trigonometric ratio

Answer»

ANSWER:

$\displaystyle{\boxed{\red{\sf\:\sin\:A\:=\:\dfrac{1}{\sqrt{10}}}}}$

$\displaystyle{\boxed{\pink{\sf\:\cos\:A\:=\:\dfrac{3}{\sqrt{10}}}}}$

$\displaystyle{\boxed{\green{\sf\:\tan\:A\:=\:\dfrac{1}{3}}}}$

$\displaystyle{\boxed{\blue{\sf\:\sec\:A\:=\:\dfrac{\sqrt{10}}{3}}}}$

$\displaystyle{\boxed{\red{\sf\:\cot\:A\:=\:3}}}$

Step-by-step-explanation:

We have GIVEN that,

$\displaystyle\sf\:cosec\:A\:=\:\sqrt{10}$

We have to FIND all the REMAINING TRIGONOMETRIC ratios.

Now,

$\displaystyle\sf\:cosec\:A\:=\:\sqrt{10}$

$\displaystyle{\pink{\sf\:\sin\:A\:=\:\dfrac{1}{cosec\:A}}\sf\:\:\:-\:-\:-\:[\:Trigonometric\:identity\:]}$

$\displaystyle{\implies\boxed{\red{\sf\:\sin\:A\:=\:\dfrac{1}{\sqrt{10}}}}}$

─────────────────────

Now,

$\displaystyle{\pink{\sf\:1\:+\:\cot^2\:A\:=\:cosec^2\:A}\sf\:\:\:-\:-\:[\:Trigonometric\:identity\:]}$

$\displaystyle{\implies\sf\:1\:+\:\cot^2\:A\:=\:\left(\:\sqrt{10}\:\right)^2}$

$\displaystyle{\implies\sf\:1\:+\:\cot^2\:A\:=\:10}$

$\displaystyle{\implies\sf\:\cot^2\:A\:=\:10\:-\:1}$

$\displaystyle{\implies\sf\:\cot^2\:A\:=\:9}$

$\displaystyle{\implies\sf\:\cot\:A\:=\:\sqrt{9}}$

$\displaystyle{\implies\boxed{\pink{\sf\:\cot\:A\:=\:3}}}$

─────────────────────

Now,

$\displaystyle{\pink{\sf\:\tan\:A\:=\:\dfrac{1}{\cot\:A}}\sf\:\:\:-\:-\:-\:[\:Trigonometric\:identity\:]}$

$\displaystyle{\implies\boxed{\green{\sf\:\tan\:A\:=\:\dfrac{1}{3}}}}$

─────────────────────

Now,

$\displaystyle{\pink{\sf\:\tan\:A\:=\:\dfrac{\sin\:A}{\cos\:A}}\sf\:\:\:-\:-\:[\:Trigonometric\:identity\:]}$

$\displaystyle{\implies\sf\:\dfrac{1}{3}\:=\:\dfrac{\dfrac{1}{\sqrt{10}}}{\cos\:A}}$

$\displaystyle{\implies\sf\:\cos\:A\:=\:\dfrac{\dfrac{1}{\sqrt{10}}}{\dfrac{1}{3}}}$

$\displaystyle{\implies\sf\:\cos\:A\:=\:\dfrac{1}{\sqrt{10}}\:\times\:\dfrac{3}{1}}$

$\displaystyle{\implies\boxed{\blue{\sf\:\cos\:A\:=\:\dfrac{3}{\sqrt{10}}}}}$

─────────────────────

Now,

$\displaystyle{\pink{\sf\:\sec\:A\:=\:\dfrac{1}{\cos\:A}}\sf\:\:\:-\:-\:[\:Trigonometric\:identity\:]}$

$\displaystyle{\implies\sf\:\sec\:A\:=\:\dfrac{1}{\dfrac{3}{\sqrt{10}}}}$

$\displaystyle{\implies\sf\:\sec\:A\:=\:1\:\times\:\dfrac{\sqrt{10}}{3}}$

$\displaystyle{\implies\boxed{\red{\sf\:\sec\:A\:=\:\dfrac{\sqrt{10}}{3}}}}$
