Answer:

Add the river’s velocity to the boat’s velocity

Explanation:

It is given that,

A river current has a velocity of 5 km/h relative to the shore. A boat moves in the same direction as the current at 4 km/h relative to the river. We need to calculate the velocity of the boat relative to the shore.

As the two vectors are going in same direction. So, the velocity of the boat relative to the shore can be calculated by adding the river's velocity to the boat's velocity. So, the correct option is (c) "add the river’s velocity to the boat’s velocity".

How are ice liquid water and water vapor different from each other?
olga_2 [115]
The molecules of ice stick together in the process of cohesion. They are tightly packed so there isn't much room to move. Liquid water is a looser hold. The molecules can go past one another, and they will take the shape of whatever container they occupy. Water vapor is loosely contained, and it will will fill whatever container it is kept in, and it will take its shape, too.

A 32-n force acts on a small mass in the positive x-direction. a 26-n force also acts on it in the negative x-direction. what is
motikmotik

Equilibrium force is the force that will keep the small mass in place, hence no movement must be made. So we know that 32 N of force is acted towards the positive direction so +32 N. Which is counteracted by 26 N force so:

32 N – 26 N = 6 N (positive)

Since positive 6 is left, therefore this must be acted by an equilibrant negative 6 N.

 

Answer:

<span>- 6 N </span>
