The 1st quadrant (0-90 degrees) is the only quadrant where none of the components are negative, so that means that any angle larger than 90 degrees will result in one of the components being negative.

Answer:

Angle must be greater than 90 to make one or more components of a vector negative.

Explanation:

There are four ranges of angle given below:

(i) For 0 < θ < 90, both components are positive.

(ii) For 90 < θ < 180, x-component is negative while y-component is positive.

(iii) For 180 < θ < 270, both components are negative.

(iv) For 270 < θ < 360, x-component is positive while y-component is negative.

Hence, angle must be greater than 90 to make one or more components of a vector negative.

serious [3.7K]

Answer:Greenhouse effect

Explanation:

Short wavelength radiation from the sun passes through a  planet's atmosphere but some of the outgoing long-wavelength energy is absorbed and radiated again this process is known as Green house effect which increases the temperature of earth and as a result causes more to be trapped inside earth atmosphere.
