5.

A stone is projected horizontally from the top of a tower with a speed of 4m/s lands on the ground at a horizontal distance of 25m from the foot of the tower. Calculate the height of the tower.

Answer»

Firstly we need to find the TIME taken to reach the ground USING horizontal speed and distance covered horizontally

t = x/v

or t = 80/5 = 16 s

Now using the kinematic expression for vertical motion, initial vertical motion being 0 m/s

s = ut + ½ at^2

and taking coordinate axes at the top of tower, noting that gravity acts in a DIRECTION opposite to the positive up direction. If H is height of tower then equation BECOMES

(- h) = 0×16 + ½ (-10) 16^2

or h = 1280 m

6.

Check the correctness of Equation wring dimension1) work done =mgh​

Answer»

Solution :-

We need to check the correctness of he equation , W = MGH by writing the DIMENSIONS

Here , as we know that

Dimension of work ( W ) is [ML²T-²]

So,

[ML²T-²] = mgh

By substituting the dimensions of mgh, we need to prove that LHS = RHS so the given equation is correct .

Now taking RHS and proving

Substituting the dimensions ,

• m → M

• g → LT-²

• h → L

⇒ M × LT-² × L

⇒ ML²T-²

Now COMPARING with LHS

ML²T-² = ML²T-²

• LHS = RHS

Hence , the given equation is correct

Why does glass dont show refraction?​

Answer»

Answer:

The glass doesn't show refraction as this light does not CHANGE MEDIUM, and also there is a change of medium from air to glass and back into the air. Because the glass is so THIN and because the light STARTS and finished in air, the refraction into and out of the glass causes little deviation in the light's original direction.

Hope it helps you!

4500 J of energy is used to raise an object with a mass of 50 kg to a height h .Calculate h

Answer»

Given :-

  • Potential ENERGY (P.E) = 4500 J
  • Acceleration de to gravity (g) = 10 (APPROX of 9.8)
  • MASS (m) = 50 kg.

To Find :-

  • Height (H)

We have to find the height (h) here and we know the formula of Potential Energy (P.E) = m × g × h

In this, we have P.E , m & g and h isn't there

So, we PUT the values and solve it

→ P.E = m × g × h

→ 4500 = 50 × 10 × h

→ 4500 = 500 h

→ 500h = 4500

→ h = 4500/500

→ h = 9

Thus, the height is 9 m

a car falls off a ledge and drops to the ground in 0.9s. if the value of gravitational is 10m/s2,then the speed striking the ground is​

Answer»

Given :-

  • Initial velocity, u = 0 m/s
  • TIME taken, t = 0.9s
  • Acceleration due to gravity, g = 10 m/s²

To find :-

  • Final velocity - v

Solution :-

  • u = 0 m/s
  • t = 0.9s
  • g = 10 m/s²

Substituting the value in 1st equation of motion :-

\sf v = u + at

\sf v = 0 + 0.9 \times 10

\sf v = 9 m/s

Velocity with which it STRIKES the GROUND is 9 m/s.

An electric pump has 2kW power. How much water will the pump lift every minute to a height of 10 m ? ​

Answer»

GIVEN:-

power=2kW=2000W

h=10m

t=1 MIN=60 sec

g=10 m/s^2

power =  \frac{work \: done}{time}

2000 =  \frac{work \: done}{60}

work \: done = 2000 \times 60 -  - (1)

and,

work \: done = mgh -  - (2)

by EQ. 1 and 2

2000 \times 60 = m \times 10 \times 10

m = 60 \times 20

m = 1200 \: <klux>KG</klux>

so, 1200 kg of water PUMP every min

A cell supplies a current of 1.8A through two resistors in parallel, when the resistors are in series the current is 0.6A. calculate the resistance.

Answer»

Answer:

I HOPE IT'S HELPFUL TO YOU BRO....

The total resistance of a circuit connected to the given cell of emf 15 V is the sum of all the resistances from various sources like, resistors, ammeter, voltmeter, etc., connected in series along with the internal resistance of the cell.

In this case, the total resistance is given as 3Ω+3Ω+6Ω=12ohms.

From the ohm's law the total current can be calculated from the FORMULA I=V/R.

That is, I=

R

V

=

12A

15V

=1.25A.

Hence, the current through the battery is 1.25 amperes.

The voltage output of a device is measured across its terminals and is CALLED its terminal voltage V. Terminal voltage is given by the equation V=emf−Ir.

( 4 ) Circumcentre of an acute angled triangle is.....................of the triangle.(A) On one side(C) on one angle(B) in the interior(D) in the exteriorplz fast ​

Answer»

ANSWER:

In the interior

Explanation:

CIRCUMCENTER of a triangle is formed by JOINING the perpendicular bisectors of three sides of triangle.

As we draw perpendicular bisectors of three sides, they will intersect at one point(say O) which lies inside the circle.

From that point of INTERSECTION, draw a circle touching each of the VERTEX of a triangle and we get a circumcircle. And O becomes centre of the circle.

Hence, circumcenter lies inside the triangle.

Application of work energy theorem​

Answer»

Answer:

see below..

Explanation:

Work-Energy THEOREM is very useful in analyzing situations where a rigid body moves under several forces. As we know that a rigid body cannot store potential energy in its lattice due to rigid structure, it can only POSSESS KINETIC energy. Thus the work done by any force acting on a rigid body is EQUAL to the change in its kinetic energy. This is the basis of work energy equation for rigid bodies.

starting from rest a car is moving with uniform acceleration imagine what happens to the displacement covered if time of travel is doubled ​

Answer»

Given :  starting from rest a car is moving with uniform acceleration

To Find : what happens to the displacement covered if time of travel is DOUBLED? ​

Solution:

S = ut + (1/2)at²

S = Displacement

u = initial velocity

a = acceleration

t = time

Let say t = T

u = 0 as start from rest

S =0 + (1/2)aT²

=> S =(1/2)aT²

if time is doubled

t = 2T

=> S = 0 + (1/2)a(2T)²

=> S = 4((1/2)aT²)

Displacement will be 4 times if time is doubled
