Solutions
S1. (a)
Sol-
• Current carrying conductor produces magnetic field.
S2.(a)
• An ideal voltmeter has infinite resistance.
• The current flow in ideal voltmeter is zero.
S3. (b)
• Regulator is used to change the speed of the fan.
S4. (C)
• The layer of the atmosphere that reflects radio waves is the ionosphere.
• The ionosphere is defined as the layer of the earth’s atmosphere that is ionized by solar and cosmic radiation.
S5. (a)
• Both magnetic field and electric field is produced due to the moving electric charge.
S6.(d)
• NOT gate is a logic gate and referred as an inverter.
• It can be operated by the only one transistor.
S7. (C)
• When barometer dips suddenly, it indicates the storm like condition in weather.
S8. (b)
These colors are often observed as light passes through a triangular prism. Upon passage through the prism, the white light is separated into it’s component color’s.-red, orange, yellow, green, blue and violet.
The separation of visible light into it’s different colors is known as dispersion.
S9. (d)
• Mass is defined as the amount of substance that an object has.
• It has no direction hence, it is physical, fundamental, scalar quantity.
S10. (d)
• Pascal’s law states that if there is a change occurring in the pressure at any point in a confined fluid.
• It will transmit throughout the fluid and the same change will occur everywhere.
In the last month i.e. in May daily we will provide you with a test of the previous years’ question papers, this will increase your confidence of solving the real exam and will make you familiar with the real-time exam.
