' C ' is the only correct statement on the list. We don't know anything about diagram-x or diagram-y because we can't see them.
Answer:
sum of these two vectors is 6.06i+3.5j-3.5i+6.06j = 2.56i+9.56j
Explanation:
We have given first vector which has length of 7 units and makes an angle of 30° with positive x-axis
So x component of the vector 
y component of the vector 
So vector will be 6.06i+3.5j
Now other vector of length of 7 units and makes an angle of 120° with positive x-axis
So x component of vector 
y component of the vector 
Now sum of these two vectors is 6.06i+3.5j-3.5i+6.06j = 2.56i+9.56j
Answer:
i think c
Explanation:
because cars run on mechanical energy and solar powered means its by the sun which is light energy
<span>The force that opposes the movement of an object through
water is called drag. This is a type of frictional force. This force normally
depends on the density and the viscosity of the fluid in question. The liquid
which has more density and more viscosity or stickiness will produce a greater
amount of drag force on an object than a fluid that is less dense and less
viscous in nature. River water normally
has less drag than that of sea water. </span>
