By unplugging unused devices, by turning off any unused lights, and by switching your lightbulbs to something more energy efficient.
John's truck has more mass than his brother Thomas' truck.
John's truck has more inertia than Thomas' truck.
If both trucks get equal force, John's truck will accelerate more slowly than Thomas' truck.
John's truck needs more force to accelerate.
If both trucks are just sitting there, John's truck needs more force to start moving.
We don't know anything about the efficiency of either truck. Or the efficiency of either brother, for that matter.
Answer:The mechanical advantage of a machine is always less than its velocity ratio.It is because mechanical advantage decreases due to the friction and weight of moving parts of the machine, but the velocity ratio remains constant.
Explanation: hope this helps
I would say B. Hope this helps Plz give a thx

a)
b)
c)
Explanation:
A unit vector is a vector whose magnitude (length) is equal to 1. This kind of vector is identified as and the way to calculate is as follows:
Where:
is the vector
is the magnitude of the vector
Having this information clarified, let's begin with the answers:
a) Force Vector
Magnitude of :
<u />
<u>Unit vector:</u>
b) Displacement Vector
Magnitude of :
<u />
<u>Unit vector:</u>
c) Velocity Vector
Magnitude of :
<u />
<u>Unit vector:</u>
