Answer:
2s
Explanation:
It takes the car 1 second to decelerate 12m and it decelerated 24m (as 36 - 12 = 24)
Answer:
Clouds of gas and dust as well as new star formation are typically seen in Spiral galaxy
Explanation:
The ingredients for star formation are gas and dust, a spiral galaxy is a group of stars that are together as a consequence of the gravitational pull between them and, as the name said it, has a spiral shape.
They are composed for a central bulge, a disk (in which a spiral arms structure can be seen), gas and dust. Because of the presence of gas and dust, star formation is possible.
Answer:
Step 1: Draw the vectors[Ref. Fig.]
Consider there are two vectors A and B such that B is perpendicular to the resultant R
Since the resultant is perpendicular to vector B we will get a right-angled triangle
Step 2: Equation formation
From the triangle
∣A∣2=∣B∣2+∣R∣2 ....(1)
Given , ∣R∣=∣A+B∣=12 ....(2)
∣A∣+∣B∣=18 ....(3)
Step 3: Solving Equations
Equation (3) and (1)⇒ ∣A∣2=(18−∣A∣)2+(12)2
⇒ ∣A∣2=182+∣A∣2−2×18∣A∣+
