<h2>Hello!</h2>
The answer is: B. In the opposite direction from the action force.
<h2>
Why?</h2>
Newton's third law states that there is always a force acting in the opposite direction from the first applied force to an object, the second force will have the same magnitude but the opposite direction.
For example, when we sit on a chair, there is a force applied on the chair (our weight), at the same time, there is an equal force but with opposite direction going from the chair to us.
There are other two laws established by Newton, and they are related to the object's movement, acceleration, forces, masses, and velocity.
Have a nice day!
Answer:
sorry I don't understand this language
Answer:
h = 0.1 m = 10 cm
u = 0.2 m = 20 cm
v = 0.06 m = 6 cm
m = h'/h = v/u
h'/10 = 6/20
h' = 60/20 = 3 cm
Therefore image height = 3 cm(0.03 m)
Hope this helps!
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.
It is E=something which leases another something equaling another something
