"A hiker starts at point P and walks 2.0 kilometers due east and then 1.4 kilometers due north. The vectors in the diagram below

represent these two displacements.
On the diagram in your answer booklet, use a ruler to construct the vector representing the hiker’s resultant displacement."

Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]

Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35  [ tan 35 = 0.70 ]

In short, Your Answer would be 35 degrees

Hope this helps!

Nitella [24]

Pascal's law states that the pressure exerted on an incompressible fluid and in equilibrium within a container of non-deformable walls is transmitted with equal intensity in all directions and at all points of the fluid. In other words, it could be summed up further, stating that any pressure exerted on a fluid will spread over the entire substance evenly.

When Superman puts the stone on one side of the hydraulic system, the weight of the stone creates a pressure on the fluid that ends up being transmitted to lift the piston attached to the large stone. In order for the law of conservation of energy to exist and be maintained, the small stone has to move a lot so that the large stone moves only slightly, but moves safely.

Andy pushes a box to the right with 5 N of force. Kristen pushes the box to the left with 3 N of force. What will be the resulti
REY [17]
The forces are applied in opposite direction.
So the net force will be the difference of both forces.
net force =5-3=2N

This force will be in direction of 5N(bigger force) means in direction which Andy is pushing.

A film badge worn by a radiologist indicates that she has received an absorbed dose of 2. 5 x 10-6 gy. the mass of the radiologi
Anestetic [448]

Energy absorbed by the radiologist is 1.775*10^-6J.

To find the answer, we have to know about the radiation.

<h3>How much energy has she absorbed?</h3>
  • We have the expression for dose of absorption as,

           D=\frac{E}{m}

where; E is the energy absorbed and m is the mass of the body.

  • From the above expression, substituting appropriate values given in the question, we get,

         E=D*m=2.5*10^{-6}J/kg*71kg=1.775*10^{-4}J

Thus, we can conclude that, the Energy absorbed by the radiologist is 1.775*10^-6J.
