Answer: 35 degree Celsius
Explanation: Subtract both the temperatures And divide by two.
When waves travel across strings, the larger the tension of the string the faster the velocity of the wave. This is because of the equation:
v = the square root of (T/(m/L)) where T is the tension, m the mass of the string, and L the length of the string
Hope this helps!
Answer:
Explanation:
We can use the equation for the speed
where x is the distance and t the time. In this case we know that the time spent was 2 hours and the distance was 150km. By replacing we have

Answer:
9.9 m/s
Explanation:
Given:
Δy = 5 m
v = 0 m/s
a = -9.8 m/s²
Find: v₀
v² = v₀² + 2aΔy
(0 m/s)² = v₀² + 2 (-9.8 m/s²) (5 m)
v₀ = 9.9 m/s
