Answer:
The value is 
Explanation:
From the question we are told that
The radius of curvature is 
Generally the radius of curvature is mathematically represented as
Here 
is the focal length hence
=> 
=>
Mass m = 25 Kg; Force = Weight = mg Force = ma but a = g
F = 40.8 N
Required: gravity g = ?
F = mg
g = F/m
g = 40.8 N/25 Kg
g = 1.6 m/s²
Answer:
-2.79 m/s²
Explanation:
Given:
v₀ = 20 m/s
v = 11 m/s
Δx = 50 m
Find: a
v² = v₀² + 2aΔx
(11 m/s)² = (20 m/s)² + 2a (50 m)
a = -2.79 m/s²
Round as needed.
Answer:
last is the answer.
increase the voltage in order to send energy faster.
Sound waves, duh. What do u expect?
