Answer:
Area is a vector quantity.
Explanation:
A vector quantity has both magnitudes as well as direction. On the other hand a scalar quantity has only magnitude.
Out of given options,
Volume and mass is a scalar quantity because they don't have directions. While area can be taken as a vector quantity. The direction of area vector of a surface is along perpendicular to the surface.
Hence, the correct option is (d).
If the motorist travelled at 20 meters a second for three minutes, 3 minutes is the same as 180 seconds, you multiply 20 times 180, which equals 3600, add 25, and the answer is 3625.
Answer:
Q=cmΔT
Q1(steel)=Q2(water)
c1•m1• (t1-t) = c2•m2• (t-t2)
628•0.1•(80-t) = 4180•0.2• (t-10)
5024-62.8t = 836t -8360
5024+8360=(836+62.8)t
t=14.9°C
Answer: a force is simply a push or pull.
The SI unit for force is Newton(N) or kgm/s2
When the net force on an object is not zero the forces are said to be unbalanced since they do not cancel out each other .
When two forces act in opposite directions we substract the forces in order to get the resultant force acting on the object.
