Which of the following can be computed?
Musya8 [376]
Answer: only the third option. [Vector A] dot [vector B + vector C]

The dot between the vectors mean that the operation to perform is the "scalar product", alson known as "dot product".

This operation is only defined between two vectors, not one scalar and one vector.

When you perform, in the first option, the dot product of any ot the first and the second vectors you get a scalar, then you cannot make the dot product of this result with the third vector.

For the second option, when you perform the dot product of vectar B with vector C you get a scalar, then you cannot make the dot product ot this result with the vector A.

The third option indicates that you sum the vectors B and C, whose result is a vector and later you make the dot product of this resulting vector with the vector A. Operation valid.

The fourth option indicates the dot product of a scalar with the vector A, which we already explained that is not defined.

When two objects interact, the change in momentum of the first object is ______ the change in momentum of the second object.
Mariulka [41]

Answer:

A. Equal to and Opposite

Explanation:

           when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .

        Given that there are 2 bodies

         Let  P₁ as first object's momentum

                  P₂ as second object's momentum.

                  Total Momentum =P₁ + P₂

           As there is no external force acying on the system

                 Change in the Total momentum is zero

so,

                  0 = Δ P₁ + ΔP₂

                   ΔP₂ = -ΔP₁

                   negative sign indicates opposite direction.

                       Both are of equal magnitude.

Sunny_sXe [5.5K]

Answer: D

X and Y

Explanation:

X The least amount of magnesium Took in magnesium

Y Slightly less magnesium than the cell Took in magnesium

Because active transport occurs when ions or molecules move from less concentration region to high concentration region through semi membrane with the help of some energy.

Please help me very urgent :((
Stells [14]

Answer:

-150 N

Explanation:

(Newton's second law) F=ma

Sum of forces in Y direction= (+200 N)+(-200 N)= 0...

forces cancel, object does not accelerate up/down

Sum of forces in X direction= (+65 N)+(-65 N)+(-150 N)

= -150 N

notice that the +/- 65 components cancel, leaving a net force of 150 N in the LEFTwards direction (which is typically defined as negative)

Overall, the net force is -150 N
