17.	A body of mass'm' slides down a smooth inclined plane having an inclination of 45° with the horizontal. It takes2s to reach the bottom. If the body is placed on a similarplane having coefficient friction 0.5, what is the time taken for it to reach the bottom?
Answer» Given :- A body of MASS m slides down a smooth inclined plane having an inclination of 45° with the horizontal. It takes the body 2 seconds to reach the bottom. To Find :- Time taken by the body if the coefficient of friction of the plane is 0.5 Solution :- Let's find the distance travelled by the body using the first case. SINCE the plane is smooth in this case, So there will be no frictional force opposing the motion of the body down the inclined plane. So, Acceleration with the INCLINE is g sin θ, Using second equation of motion, ⇒ s = UT + 1/2 at² ⇒ s = 1/2 × g sin θ × 2² ⇒ s = 2 × 10 × sin 45° ⇒ s = 20 × 1/√2 ⇒ s = 10√2 units. In the second case, we have friction, So it will oppose the motion of body, Here, The acceleration would become ⇒ g sin θ - μ g cos θ ⇒ 10×sin 45° - 0.5 × 10 × cos 45° ⇒ 5√2 - 5√2 / 2 ⇒ ( 10√2 - 5√2 ) / 2 ⇒ 5√2/2 unit/s² Now, Let us find the time taken by the body to cover 10√2 unit. Using second equation of motion, ⇒ s = ut + 1/2 at² ⇒ 10√2 = 1/2 × 5√2 / 2 × t² ⇒ 10√2 = 5√2 / 4 × t² ⇒ 40√2 / 5√2 = t² ⇒ 8 = t² ⇒ t = 2√2 seconds Hence, The body will take 2√2 seconds.

A body of mass'm' slides down a smooth inclined plane having an inclination of 45° with the horizontal. It takes2s to reach the bottom. If the body is placed on a similarplane having coefficient friction 0.5, what is the time taken for it to reach the bottom?

Answer»

Given :-

A body of MASS m slides down a smooth inclined plane having an inclination of 45° with the horizontal. It takes the body 2 seconds to reach the bottom.

To Find :-

Time taken by the body if the coefficient of friction of the plane is 0.5

Solution :-

Let's find the distance travelled by the body using the first case. SINCE the plane is smooth in this case, So there will be no frictional force opposing the motion of the body down the inclined plane.

So, Acceleration with the INCLINE is g sin θ,
Using second equation of motion,

⇒ s = UT + 1/2 at²

⇒ s = 1/2 × g sin θ × 2²

⇒ s = 2 × 10 × sin 45°

⇒ s = 20 × 1/√2

⇒ s = 10√2 units.

In the second case, we have friction, So it will oppose the motion of body,

Here, The acceleration would become

⇒ g sin θ - μ g cos θ

⇒ 10×sin 45° - 0.5 × 10 × cos 45°

⇒ 5√2 - 5√2 / 2

⇒ ( 10√2 - 5√2 ) / 2

⇒ 5√2/2 unit/s²

Now, Let us find the time taken by the body to cover 10√2 unit.

Using second equation of motion,

⇒ s = ut + 1/2 at²

⇒ 10√2 = 1/2 × 5√2 / 2 × t²

⇒ 10√2 = 5√2 / 4 × t²

⇒ 40√2 / 5√2 = t²

⇒ 8 = t²

⇒ t = 2√2 seconds

Hence, The body will take 2√2 seconds.

19.	A man sold two TV sets for ₹12,480 each.On one he gains 20% and on the other he loses 20%.How much does he gain or loss percent on the whole transaction
Answer» Answer Selling price of two T.V. sets =2400 RS. each Let cost price of a T.V. sets on which he gain 20% be X Rs and another T.V. sets on which he lost 20% be Y Rs. SOLVING for T.V. sets on which he gain We know that, Selling price=Cost price+profit ⇒2400=X+20% of X ⇒2400=X+0.2X ⇒2400=1.2X ⇒X=1.22400 ∴X=2000 Rs Now, Solving for T.V. sets on which he loss We know that, Selling price=Cost price−loss ⇒2400=Y−20% of Y ⇒2400=Y−0.2Y ⇒2400=0.8Y ⇒Y=0.82400 ∴Y=3000 Rs Now, Total Cost price=X+Y=2000+3000=5000 Rs and Total Selling price=2×2400=4800 Rs Since Selling price So, In whole transaction, there is a Loss of 5000−4800=200 R Hope it helps Please mark me as brainliest THANKS :)

A man sold two TV sets for ₹12,480 each.On one he gains 20% and on the other he loses 20%.How much does he gain or loss percent on the whole transaction

Answer»

Answer

Selling price of two T.V. sets =2400 RS. each

Let cost price of a T.V. sets on which he gain 20% be X Rs

and another T.V. sets on which he lost 20% be Y Rs.

SOLVING for T.V. sets on which he gain

We know that, Selling price=Cost price+profit

⇒2400=X+20% of X

⇒2400=X+0.2X

⇒2400=1.2X

⇒X=1.22400

∴X=2000 Rs

Now, Solving for T.V. sets on which he loss

We know that, Selling price=Cost price−loss

⇒2400=Y−20% of Y

⇒2400=Y−0.2Y

⇒2400=0.8Y

⇒Y=0.82400

∴Y=3000 Rs

Now, Total Cost price=X+Y=2000+3000=5000 Rs

and Total Selling price=2×2400=4800 Rs

Since Selling price

So, In whole transaction, there is a Loss of 5000−4800=200 R

21.	A 75 kg box is dropped from the top of a tower. The height of the tower is 35 m. Calculate (i) the initialpotential energy of the box, (ii) its potential energy 15 m above the ground, (iii) the maximum value ofits kinetic energy and (iv) its kinetic energy 20 m below the top of the tower. (g = 9.8 m/s2)(g = 9.8 m/s2)
Answer» Given :- A 75 kg box is dropped from the top of a tower of HEIGHT 35 m. Acceleration due to gravity, g = 9.8 m/s² To FIND :- Initial potential energy. Potential energy 15 m above the ground. Maximum value of KINETIC energy Kinetic energy 20 m below the top of the tower. Solution :- First, Let us find the Initial potential energy at the top of the tower, ⇒ PE = mgh ⇒ PE = 75 × 9.8 × 35 ⇒ PE = 25,725 J _______________________ Here, We have Height, h = 15 m above the ground. g = 9.8 m/s² mass = 75 kg ⇒ PE = mgh ⇒ PE = 75 × 9.8 × 15 ⇒ PE = 11,025 J _______________________ Maximum value of the kinetic energy will be at the very bottom of the tower ( touching the ground ) where all the potential energy will be CONVERTED into Kinetic energy (According to law of conservation of energy) So, ⇒ Maximum Kinetic energy = PE at the top of tower ⇒ Maximum Kinetic energy = 25,725 J _______________________ Here, we have to find the kinetic energy 20 m below the top of the tower. Let's find the potential energy at this point, we have Height, h = 35 - 20 = 15 m g = 9.8 m/s² mass = 75 kg So, ⇒ PE = mgh ⇒ PE = 75 × 9.8 × 15 ⇒ PE = 11,025 J But, The total kinetic energy should be 25,725 J including the kinetic energy, according to the law of conservation of energy, ⇒ Total energy = PE + KE ⇒ 25,725 = 11,025 + KE ⇒ KE = 25,725 - 11,025 ⇒ KE = 14,700 J

A 75 kg box is dropped from the top of a tower. The height of the tower is 35 m. Calculate (i) the initialpotential energy of the box, (ii) its potential energy 15 m above the ground, (iii) the maximum value ofits kinetic energy and (iv) its kinetic energy 20 m below the top of the tower. (g = 9.8 m/s2)(g = 9.8 m/s2)

Answer»

Given :-

A 75 kg box is dropped from the top of a tower of HEIGHT 35 m.
Acceleration due to gravity, g = 9.8 m/s²

To FIND :-

Initial potential energy.
Potential energy 15 m above the ground.
Maximum value of KINETIC energy
Kinetic energy 20 m below the top of the tower.

Solution :-

First, Let us find the Initial potential energy at the top of the tower,

⇒ PE = mgh
⇒ PE = 75 × 9.8 × 35
⇒ PE = 25,725 J

_______________________

Here, We have

Height, h = 15 m above the ground.
g = 9.8 m/s²
mass = 75 kg

⇒ PE = mgh
⇒ PE = 75 × 9.8 × 15
⇒ PE = 11,025 J

_______________________

Maximum value of the kinetic energy will be at the very bottom of the tower ( touching the ground ) where all the potential energy will be CONVERTED into Kinetic energy (According to law of conservation of energy)

So,

⇒ Maximum Kinetic energy = PE at the top of tower

⇒ Maximum Kinetic energy = 25,725 J

_______________________

Here, we have to find the kinetic energy 20 m below the top of the tower.

Let's find the potential energy at this point, we have

Height, h = 35 - 20 = 15 m
g = 9.8 m/s²
mass = 75 kg

So,

⇒ PE = mgh
⇒ PE = 75 × 9.8 × 15
⇒ PE = 11,025 J

But, The total kinetic energy should be 25,725 J including the kinetic energy, according to the law of conservation of energy,

⇒ Total energy = PE + KE
⇒ 25,725 = 11,025 + KE
⇒ KE = 25,725 - 11,025
⇒ KE = 14,700 J

A man sold a fan for rs 1750.00 at a loss of rs 270. find the cost price

Answer»

Given:

A fan with

Selling Price (SP) = Rs. 1750.00 or Rs. 1750
Loss = Rs. 270

What To FIND:

We have to find the COST price (CP) of the fan.

How To Find:

To find CP, we have to,

Loss = CP - SP

Solution:

USING the formula,

⇒ Loss = CP - SP

Substitute the values,

⇒ Rs. 270 = CP - Rs. 1750

TAKE Rs. 1750 to LHS,

⇒ Rs. 270 + Rs. 1750 = CP

Add the amount,

⇒ Rs. 2020 = CP

∴ Therefore, the cost price (CP) of the fan is Rs. 2020.

DATE14/02/2021Perimeter & Areafind the breadth of the rectangle whose length is 70cm& Perimeter 200cm.

Answer»

Answer:

GIVEN :-

A rectangle whose length is 70 cm and perimeter is 200 cm.

To Find :-

What is the BREADTH of the rectangle.

Formula Used :-

➲ Perimeter of a Rectangle = 2(Length + Breadth)

SOLUTION :-

Given :

Length = 70 cm
Perimeter = 200 cm

According to the question by using the formula we get,

↦ 2(70 + B) = 200

↦ 140 + 2B = 200

↦ 2B = 200 - 140

↦ 2B = 60

↦ B = 60/2

➠ B = 30 cm

∴ The breadth of a rectangle is 30 cm.

VERIFICATION :-

⇒ 2(Length + Breadth) = 200

By PUTTING Breadth = 30 we get,
