The type of image which is formed by the refracting telescope are magnified inverted and non-real image.

Answer: Option A

<u>Explanation: </u>

The refractive lens uses it lens as the objective to form an image. This type of telescope are used as spy glasses and astronomical telescopes.

The refracting telescope makes the magnified image which can be also be termed as the enlarged image. Image formed by the refracting telescope is the inverted image which can also be written as the upside down image.

The nature of image formed is non-real that is virtual image. The purpose of telescope is to see far distant object and thus needs to produce enlarged image.

A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 57.3 c

Mashcka [7]

Answer with Explanation:

We are given that

Diameter of pipe, $d_1=0.573 m$

$v_1=13.5 m/s$

$v_2=5.83 m/s$

Volume flow rate of the petroleum along the pipe= $Q_{refinery}=A_1v_1=v_(\frac{\pi d^2_1}{4})$

$Q_{refinery}=13.5\times (\pi\times \frac{0.573)^2}{4})=3.48 m^3/s$

By equation of continuity

$A_1v_1=A_2v_2$

$\frac{\pi d^2_1}{4}v_1=\frac{\pi d^2_2}{4}v_2$

$d^2_2=\frac{v_1}{v_2}d^2_1$

$d_2=\sqrt{\frac{v_1}{v_2}}d_1$

$d_2=0.573\sqrt{\frac{13.5}{5.83}}$

$d_2=0.87 m$

$d_2=0.87\time 100=87 cm$

1 m=100 cm

In energy point of view, the larger stone had more potential energy before dropping. impacting the water, the larger one, having more kinetic energy which changed from potential energy, tranfered energy to the water and formed wave. the amplitude of the wave indicate the energy of the wave. more energy more amplitude.

As the distance from equilibrium decreases, in what way is the magnitude of the force on an object that is undergoing simple har

nydimaria [60]

The correct answer is B. The force decreases.

Simple harmonic motion is a to and fro motion about the equilibrium position, with the restoring force proportional to the displacement and it is always directed towards the mean position.

Mathematically, the force F is given by,

$F= -kx$

Here, x is the displacement from the equilibrium position and k is the force constant. The negative sign indicates that the direction of the force is always directed towards the equilibrium position, opposite to the direction of the displacement from the equilibrium position.

Thus, as the displacement from the equilibrium position decreases, the force acting on the body also decreases.
