13x is that what you meant???
Answer:
5) 0 N
Step-by-step explanation:
According to Newton's second law of motion: "The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the object's mass" .
Because the vehicle travels at a constant speed, its acceleration at zero, so
,
Answer: 4 pounds > 60 ounces (D)
Step-by-step explanation:
Since there are 16 ounces in a pound, you just multiply 16 (ounces) by 4 (pounds). If you evaluate 16*4, you would get 64 ounces, so 64 is greater than 60. So the answer is D.
Answer: a) AB = ; b) ; c) No, they are different; d) No, they are never the same;
Step-by-step explanation:
a) A = , B = . This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.
AB = . =
b) BA = . =
c) As, we can see, parts a and b are differents.
d) With matrices, multiplication is not commutative, which means AB≠BA
