-
A. 1.05m/s²
-
B. 1.15m/s²
-
C. 1.25m/s²
-
D. None of these
Explanation
To find acceleration, we use the formula:
a = (v - u) / t
where:
v = final velocity = 15 m/s
u = initial velocity = 10 m/s
t = time = 4 seconds
a = (15 - 10) / 4
= 5 / 4
= 1.25 m/s²
درجہ حرارت میں اضافے کے ساتھ ، _____ کی رفتار؟
-
A. Gases increases and liquids decreases
-
B. Gases decreases and liquids increases
-
C. None of these
-
D. Both gases and liquids increases
Explanation
- In gases, as temperature increases, the particles move faster, resulting in increased velocity.
- In liquids, an increase in temperature reduces the intermolecular forces, causing slower movement and a decrease in velocity.
