    What color does blue and yellow make?

    Green Color will be formed when Blue and Yellow colors get mixed. Red, Yellow, and Blue are said to be the primary colors and form the RYB Color Model which is said to be a subtractive color model. [adinserter block="7"] Different color combinations include: Red + Yellow = Orange Red + Blue = VioletRead more

    Explanation: The total distance covered by the sound from the point of generation to the reflecting surface and back should be at least 344 m/s (speed of sound) × 0.1 s = 34.4 m.

    Explanation:

    The total distance covered by the sound from the point of generation to the reflecting surface and back should be at least 344 m/s (speed of sound) × 0.1 s = 34.4 m. Thus, for hearing distinct echoes, the minimum distance of the obstacle from the source of sound must be half of this distance. I.e., 34.4/2 = 17.2 m.

    Explanation:

    RADAR – RAdio Detection And Ranging.

    A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects.

    Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

    Radio waves from the transmitter reflect off the object and return to the receiver, giving information about the object’s location and speed.

    Explanation: Force = Mass × Acceleration = m × a Force has magnitude as well as direction. It is a vector quantity. 20 = 10 × a a = 2 m/sec²

    Explanation:

    Force = Mass × Acceleration = m × a

    Force has magnitude as well as direction. It is a vector quantity.

    20 = 10 × a

    Explanation:

    Zeeman Effect:- It is the name of the phenomena in physics and astronomy which involves the splitting of a spectral line into two or more components of slightly different frequencies when the light source is placed in a magnetic field.

    It is named after the Dutch physicist Pieter Zeeman.

    The effect is caused due to the distortion of the electron orbitals because of the magnetic field.

    This effect is very useful n investigating the charge/mass ratio and magnetic moment of an electron.

    Raman Effect:- It is nothing but the change in the wavelength of light that occurs whenever a light beam is deflected by molecules.

    Alpenglow Effect:- It is an atmospheric optical phenomenon. It makes mountains appear to glow in a light pink or red hue after the Sun sets or just before it rises.
