The image is formed at the distance 50/3 from the concave mirror .

The reflective surface of a concave mirror is curved inward and away from the light source. Concave mirrors focus light inward to a single focal point. In contrast to convex mirrors, the image formed by a concave mirror changes depending on the distance between the object and the mirror.

Given ,

In concave lens

focal length f =+25

object distance  u =20cm

Using lens formula, we have

1/f=1/v-1/u

1/25=1/v-1/20

1/v=1/20-1/25=2-1/25 =1/25

v = 25 cm

Now, for concave mirror, we have

Focal length, f= R/2=25/2 = 12.5 cm

Object distance, u=+(25−50) cm= -25 cm

Using mirror formula, we have

1/f=1/v + 1/u

1/v = 1/12.5 - 1/-25 = 5-2/50 = 3/50

v = +50/3

Therefore the image is formed at the distance 50/3 from the concave mirror

Answer:

V = 140 km/h

Explanation:

Velocity is the change in position over time.

We can use the equation V = Δx / t

Note that V is the average velocity.

We are given Δx and t. Lets solve for V.

[tex]V=\frac{540}{4}[/tex]

[tex]V=140[/tex]

[tex]\frac{km}{hour}[/tex]

V = 140 km/h

The length of the ladder which is placed 3 meters from the wall is           5 meters

The rate of the change of ladder decreasing in vertical wall = - 0.15 m/s

The distance between the bottom of the ladder and the wall = 3 meter

The rate of change of the bottom of the ladder away from the wall = 0.2 m/s.

The length of the ladder can be found using the Pythagoras theorem,

               x² + y² = L²

where x is the distance between the bottom of the ladder and the wall

           y is the distance from the top of the ladder to the bottom of the wall.

           L is the length of the ladder

Let us differentiate in terms of the rate of change in the above equation,

              2x dx/dt + 2y dy/dt = 0

Now let us substitute the known values,

                 2(3)(0.2) + 2y(-0.15) = 0

                           1.2  - 0.3y = 0

                                 0.3y = 1.2

                                      y = 1.2 / 0.3

                                        = 4

Then, the length of the ladder is

               3² + 4² = L²

                 9 + 16 = L²

                        L = √25

                        L = 5

Therefore, the length of the ladder is 5 meters

The correct answer is D. (The force of ball on bat and the force of the bat on ball.

Baseball is a game that we need to hit the ball using bat as hard as we can to make the ball fly as far as we can when other player will throw the ball as fast as possible to make it hard to hit.

The ball that pitcher throw has a velocity and acceleration. a ball with velocity will have some Force according to Newton's second Law. On the other side, batter will hit the ball using force from his swing. When the ball and the bat make contact, each force will negate each other. So, in order to make the ball fly high the batter need to give higher force than the force that the ball has.

Newton's Second Law tell us about that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the object’s mass.

From that statement we can conclude that the force of an object will get bigger when they move faster

a) The frequency of fundamental mode of vibration of steel piano is 400Hz.

b) The number of the highest harmonic that could be heard by a person is 24ᵗʰ.

In the given question we have,

lenth of steel piano wire (L) = 0.4 m

tension/ force on steel piano (T) = 800N

mass of steel piano (m) = 3g = 0.003 kg

We shall find out the frequency of fundamental mode of vibration of steel piano.

Fundamental Frequency of object depends on wave speed in turn which depend on tension .

Using Fundamental Frequency,

f₁ = v/2L

where , v---> wave speed

f₁ ---> fundamental frequency

L ---> length of wire

Firstly, we have to find out the value of wave speed.

For determining the wave speed we use following relation,

v = sqrt ( T/ μ )

where, v---> wave speed

T ---> Tension or force

μ ----> mass per unit length = m/L

Now, put all given values in formula

μ = m/L = 0.003/0.4 kg/m =

v = √800×0.40/(3× 10⁻³) = 327m/sec

fundamental frequency (f₁) = 327/(2×0.4 )

= 400Hz

b) The nth harmonic has frequency , fₙ = n f₁

wher, f₁---> fundamental frequency

fₙ----> highest frequency

n ----> harmonic number

fₙ = 10,000 Hz , f₁ = 409Hz

put in above formula, 10,000 = n × 409

=> n = 100/4 = 24.4

So, 24th harmonic is the highest harmonic that could be heard by a person who is capable of hearing frequenies upto 10,000Hz.

In this question, we have given a basketball hoop that is 3.05 m above the playing surface and the basket is made. The basketball was launched from a height of 1.95 And if the ball travels the original distance of 5.2 m in two seconds, then we have to find the initial velocity of the basketball. So we can find given data is we have given the horizontal distance traveled, that is d is equals to 5.2 m Per meter. And we have given the time taken to cover this distance, that is T equals to two seconds. So we can find the original velocity. So we can see that horizontal velocity that is three X is equal to, this is 5.2 upon two, and this will come out to be 2.6 meter per second. Now we can see that as we have given That the basketball hoop is 3.05 m above the playing surface. So we can say that the height covered, that is delta edges 3.5 minus 1.95. And this will comes out to be 1.10 m. So, using the equation of motion, we can find the vertical velocity Y. So we can say that that is is, we can apply in and wind direction. So we can say that delta edge is equals to this is initial velocity in y direction into time, T plus half into exhalation in y direction into T square. So we can say this is equals to 1.10, that is we're not y and to time is two seconds blood half into disease. Here, exploration is the gravitational acceleration and it is acting downwards. So this is equal to -3, which is -9.8 into two square. So from here we can find the value of velocity in the Y direction. That is 10.35 m/s. So we have the velocity in X direction and velocity in the Y direction. So we can see that the initial velocity that is we note is equal to this under root of we're not in extraction plus we're not wise square. So we can say this is equal to under root of 2.60 sq Plus 10.35 ft sq. And this will comes out to be 10.67 m/s. But this is the answer of arguing cushion. Thank you.

Capacitance is directly proportional to the electrostatic force field between the plates. This magnetic field gets stronger the closer the plates are to each other. Therefore, the capacitance increases as the distance between the plates decrease.

Therefore, we can conclude that doubling the area and distance between the plates of a parallel plate capacitor does not change the capacitance.
