Answer:
Work done = 4 J
Final Kinetic Energy = 4 J
Explanation:
From the question,
Work done = force × distance
W = F×d................... Equation 1
Given: F = 4.0 N, d = 1.0 meter.
Substitute these values into equation 1
W = 4×1
W = 4 Joules.
Also,
Kenetic Energy = 1/2 × mass × velocity×velocity.
K.E = 1/2(mv²)........... (2).
But,
F = ma
Where F = 4 N, m = 1 kg.
a = 4/1 = 4 m/s².
Using,
v² = u² + 2as............. Equation 3
Where u = 0 m/s, a = 4 m/s², s = 1 m.
Substitute into equation 3
v² = 0² +2×4×1
v² = 8
v = √8 m/s.
Substitutting into equation 2
K.E = 1/2(1)(√8)²
K.E = 1/2(8)
K.E = 4 J.
Hence the work done and the Final Kinetic energy are thesame = 4 J
Organic air? The definition of organic (from google) is: of, relating to, or derived from living matter. Air isn't living matter. Air can come from plants that are made from organic substances... Gases can pollute our air... but from my knowledge, I don't believe there that there is 'organic air'
6.5 meters per second mutiplied by 3 seconds and you get 19.5 meters
Answer:
464.3 N
Explanation:
Given parameters are:
I = 0.065 
L = 0.025 m
R = 0.28 m
= 0 m/s
= 5 m/s
t = 0.1 s
Hence, 
We must connect two torque equations to find the answer.
Where 
Hence, 
Thus, 
N
Answer: The wave can flip upside down.
Reflection is the bending of a wave when it cannot pass through. For example, plain mirrors which are flat, a ray of light hits the mirror and is reflected from the mirror since it cannot pass through
When reflection occurs the speed and frequency of the wave does not change but the wave is flipped upside down.
The speed does not change because speed is affected by the change in medium the frequency also remains the same since the energy of the wave does not change.
