Question
Given below are two statements: Statement I
A remote sensing system that possesses only a sensor and depends on an external source to irradiate the target to be called an active remote sensing system Statement II INSAT series of satellites are polar-orbiting satellites. In light of the above statements, choose the most appropriate answer from the options given below:Solution
Active remote sensing instruments operate with their own source of emission or light eg: RADAR while passive ones rely on the reflected one. INSAT is a series of multipurpose geo-stationary satellites.
What will come in the place of question mark (?) in the given expression?
?2 = 3945 ÷ 5 + 774 ÷ 6 – 77Â
125% of 80 – 6 × 4 = ? × 13 – 54
Simplify the expression:
(9x² - 25) / (3x + 5)
What value should come in the place of (?) in the following questions?
√16 * ? = √144 + (18 * 4 ÷ 3)
[∛(91125/19683 )- ∛(3375/5832 ) ] × ∛(512/9261) = ? - √(484/3969)
{(700 ÷ 20) × 40} – 30 × 18 = ?% of 1000
(96% of 1100) + 92 × 4 = ? + 46 × 16
464 + 181 +? = (154 × 25) - (15) 2 Â
19 × ? = 361 ÷ 19
