Before coming into conclusion first we have to understand both scalar and vector .
A scalar quantity is a physical quantity which has only magnitude for it's complete specification.
A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.
So the most important factor that differentiate vector from scalar is the direction.
As per the question the student is doing an experiment where he is recording the data obtained during the process.
In order to arrange them in data table, he should ask about the direction of the quantity under consideration.
Hence the correct option is the third option(C)i.e does the measurement include direction?

Answer:
equivalent power = 6.60 × 
W
Explanation:
given data
coal train length = 1.5 km = 1500 m
contain = 120 cars
holding= 110 tonnes of coal each
train traveling speed = 100 km/h = 27.78 m/s
to find out
equivalent power in watts
solution
we take here energy produce by coal is 27 × 
J/kg
and here total coal = 120 × 110 × 10³ kg
sop here energy produce by total coal is
energy produce by total coal = 27 × × 120 × 110 × 10³
and time required to cross that distance is
time = 
time = 
time = 53.99 sec
so here equivalent power will be
equivalent power = 
equivalent power = 
equivalent power = 6.60 × W

Explanation:
Social learning is a hypothesis of learning cycle and social conduct which suggests that new practices can be procured by noticing and copying others. This impacts children because they do things they do not want to.
