Your brother would be described as a speeder.
Recall the force applied to a spring and its extension/compression:
F = kΔx
Δx is the change in the spring's length (measured from its original length).
x = 0.7 m
x₀ = 0.4 m
Δx = x-x₀ = 0.7 m - 0.4 m = 0.3 m
F = 23 N
Substitute and solve for k:
23 = k×0.3
<h3>k = 7.67 N/m</h3>
Answer:
Pheasants and partridge are common and their viable population in the reserve permits controlled hunting. Endangered animals in the reserve include Musk deer, Wolf, Red panda, Cheer pheasant and Danphe. The hunting license is issued by the Department of National Parks and Wildlife Conservation.
HOPE THIS HELPS, HAVE A GREAT DAY!!
Explanation:
Speed is scalar quantity that is defined only by its magnitude and is represented with one value.
Velocity on the other side is a vector quantity that is defined with its magnitude and direction. The speedometer measures and displays the speed of the vehicle.
Where the needle points on the speedometer that is the speed of the vehicle.
The velocity is not explicitly shown, but if f the needle is moving<span>, you can get a rough idea of acceleration. If the needle is going clockwise the vehicle is accelerating.</span>
