Question 10 Which of the following equations has no real roots? Question 1 State whether the following quadratic equations have two distinct real roots. Justify your answer. Question 3 A quadratic equation with integral coefficient has integral roots. Solution: No, consider the quadratic equation with integral coefficient i. Question 4 Does there exist a quadratic equation whose coefficients are rational but both of its roots are irrational?
Solution: Yes, consider the quadratic equation with rational coefficient i. Question 5 Does there exist a quadratic equation whose coefficients are all distinct irrationals but both the roots are rationals? Solution: Yes, consider the quadratic equation with all distinct irrationals coefficients i.
The roots of this quadratic equation are 3 and 4, which are rationals. Question 6 Is 0. Solution: No, because 0. Mobile Number.

In human beings, excretory products in the form of soluble nitrogen compounds are removed by the nephrons in the kidneys. Plants use a variety of techniques to get rid of waste material. For example, waste material may be stored in the cell-vacuoles or as gum and resin, removed in the falling leaves, or excreted into the surrounding soil.
Control and coordination are the functions of the nervous system and hormones in our bodies. The responses of the nervous system can be classified as reflex action, voluntary action or involuntary action. The nervous system uses electrical impulses to transmit messages. The nervous system gets information from our sense organs and acts through our muscles. Chemical coordination is seen in both plants and animals. Hormones produced in one part of an organism move to another part to achieve the desired effect.
A feedback mechanism regulates the action of the hormones. A stream of electrons moving through a conductor constitutes an electric current. Conventionally, the direction of current is taken opposite to the direction of flow of electrons.
The SI unit of electric current is ampere. To set the electrons in motion in an electric circuit, we use a cell or a battery. A cell generates a potential difference across its terminals. It is measured in volts V. Resistance is a property that resists the flow of electrons in a conductor. It controls the magnitude of the current. The resistance of a conductor depends directly on its length, inversely on its area of cross-section, and also on the material of the conductor.
The equivalent resistance of several resistors in Class 10th Ncert Exemplar Pdf Word series is equal to the sum of their individual resistances. One watt of power is consumed when 1 A of current flows at a potential difference of 1 V.
The commercial unit of electrical energy is kilowatt hour kWh. A compass needle is a small magnet. Its one end, which points towards north, is called a north pole, and Ncert Exemplar Class 10th Science Act the other end, which points towards south, is called a south pole. A magnetic field exists in the region surrounding a magnet, in which the force of the magnet can be detected.
Field lines are used to represent a magnetic field. A field line is the path along which a hypothetical free north pole would tend to move. The direction of the magnetic field at a point is given by the direction that a north pole placed at that point would take. Field lines are shown closer together where the magnetic field is greater.
A metallic wire carrying an electric current has associated with it a magnetic field. The field lines about the wire consist of a series of concentric circles whose direction is given by the right-hand rule. The pattern of the magnetic field around a conductor due to an electric current flowing through it depends on the shape of the conductor. The magnetic field of a solenoid carrying a current is similar to that of a bar magnet. An electromagnet consists of a core of soft iron wrapped around with a coil of insulated copper wire.
A current-carrying conductor when placed in a magnetic field experiences a force. This is the basis of an electric motor. An electric motor is a device that converts electric energy into mechanical energy. The phenomenon of electromagnetic induction is the production of induced current in a coil placed in a region where the magnetic field changes with time.
The magnetic field may change due to a relative motion between the coil and a magnet placed near to the coil. If the coil is placed near to a current-carrying conductor, the magnetic field may change either due to a change in the current through the conductor or due to the relative motion between the coil and conductor.
