Answer:
9/25
Explanation:
Distance covered in the first 5 seconds:
Δx = v₀ t + ½ at²
Δx₀₋₅ = (0) (5) + ½ a (5)²
Δx₀₋₅ = 25a/2
Distance covered in the first 4 seconds:
Δx = v₀ t + ½ at²
Δx₀₋₄ = (0) (4) + ½ a (4)²
Δx₀₋₄ = 8a
So the distance covered during the 5th second is:
Δx₅ = 25a/2 − 8a
Δx₅ = 9a/2
So the ratio of the distance covered during the 5th second to the distance covered in the first 5 seconds is:
Δx₅ / Δx₀₋₅
(9a/2) / (25a/2)

Answer:
<em>The chef can make 8 casseroles</em>
Explanation:
<u>Units Conversion</u>
We need to recall 1 gallon = 16 US cups.
A casserole needs 1 cup of milk, and the chef has 0.5 gallons of milk. Those 0.5 gallons are equivalent to 0.5*16 = 8 cups, thus the chef can make 8 casseroles.
Answer:
X = 15.88 m
Explanation:
Given:
Initial Velocity V₀ = 13.4 m/s
θ = 30.1 °
g = 9.8 m/s²
To Find horizontal distance let "X" we have to time t first.
so from motion 2nd equation at Height h = 0
h = V₀y t + 1/2 (-g) t ² (ay = -g)
0 = 13.4 sin 30.1° t - 0.5 x 9.81 x t² (V₀y = V₀ Sin θ)
⇒ t = 1.37 s
Now For Horizontal distance X, ax =0m/s²
X = V₀x t + 1/2 (ax) t ²
X = 13.4 m × cos 30.1° x 1.37 s + 0
X = 15.88 m
Energy is never created or destroyed. Hope this helps!
True. Microwaves have more carrying capacity then radio waves.
