Answer:
The fall in temperature of the liquid is 8.6 +/- 0.1 ⁰C
Explanation:
Given;
initial temperature of the liquid, t₁ = 76.3 +/- 0.4⁰C
final temperature of the liquid, t₂ = 67.7 +/- 0.3⁰C
The change in temperature of the liquid is calculated as;
Δt = t₂ - t₁
Δt = (67.7 - 76.3) +/- (0.3 - 0.4)
Δt = (-8.6) +/- (-0.1)
Δt = 8.6 +/- 0.1 ⁰C
Therefore, the fall in temperature of the liquid is 8.6 +/- 0.1 ⁰C
Answer:
This would happen.
Explanation:
If the earth’s rotation speed increases then the weight of the body decreases. This is because you see a moving body on the rotating earth’s surface itself is in the reference frame. So when the earth rotates, the centripetal force acts towards the centre of rotation.
Sound waves actually travel much faster in water than air, but words and the direction of the noise are distorted.
Answer:
Distance between two adjacent wave crests = 24m
Explanation:
Distance= speed × time
Distance traveled by waves in 60 seconds (15 crests)= 15 × distance
15 × distance = 6,0 (meters/second) × 60 seconds
distance = (360 meters) / 15 = 24 meters (between two adyacent waves)
