Answer:
Explanation:
Relative velocity is defined as the velocity of an object B in the rest frame of another object A.
Answer:
1.503 J
Explanation:
Work done in stretching a spring = 1/2ke²
W = 1/2ke²........................... Equation 1
Where W = work done, k = spring constant, e = extension.
Given: k = 26 N/m, e = (0.22+0.12), = 0.34 m.
Substitute into equation 1
W = 1/2(26)(0.34²)
W = 13(0.1156)
W = 1.503 J.
Hence the work done to stretch it an additional 0.12 m = 1.503 J
Acceleration = (change in speed) / (time for the change.
change in speed = (ending speed) - (starting speed) = 9 m/s.
Acceleration = (9 m/s) / (period of 1) .
We don't know the units of the 'period of 1'.
If it means '1 second', then the acceleration is 9 m/s² .
Visible light is safe for animals because it provides them with warmth.
Newton's Second Law<span>. </span>Newton's first law of motion<span> predicts the behavior of objects for which all existing forces are balanced. The </span>first law<span> - sometimes referred to as the </span>law<span> of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Hope this helped! :)</span>
