Answer:
Third Option
Explanation:
If we have a vector A = ax + by we know that by definition
cA = cax + cby
Where c is a constant.
In this case we have two vectors
You may notice that vector B has an opposite direction to vector A.
You may also notice that | Ax | is the double of | Bx | and | Ay | is double of |By |
That is to say
So the equation that relates to vectors A and B is:
.
You can verify this relationship by performing the operation
Answer:
Explanation:
The force of gravity between two objects is given by:
where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is their separation
In this problem, we have
m1 = m2 = 1170 kg is the mass of each car
r = 28 m is their separation
Substituting,
Answer:
convection
Explanation:
By the actual movement of molecules
Answer:
2.210N
Explanation:
Workdone = Force x distance
Distance = 38m , Workdone = 84J
Hence 84J = Force x 38m
Force = 84J / 38m
Force = 2.210N =2.2N
