Answer:
The Graph Shows World Disasters.
Answer Pt.2:
As we all can see the tornado's Have the highest ratings of natural disasters, Hurricane's happen the next most, Landslide's happen less often, Wildfires also happen less often whereas Earthquakes nearly never happen, they are very rare to the world.
3. since the unbalanced forces an upward force, the object will move upward.
Explanation:
Newton's second law states that when an object is acted upon unbalanced forces, the object will experience an acceleration, whose direction is the same as the net force acting on the object, and whose magnitude is given by
where F is the net force and m is the object's mass.
From the above statement, we can say that an object accelerates in the direction of the net force acting on it. Looking at the diagram, we see that the net force on this object is upward, because the force going upward is 450 N while the force going downward is 400 N, so there is a net force:
in the upward direction. (there is no net force on the horizontal direction, since the two horizontal forces are equal and opposite)
So, the object will accelerate upward.
Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is
Thus is given by
A component of an object moving at a certain velocity can be split into its x and y components (sometimes there is a z component too, but in the case of a question like this, we can imagine the plane the helicopter is travelling in to be 2 dimensions).
Therefore, we can draw a triangle - the hypotenuse having length 86 and being 35 degrees from the ground.
Since the angle ACB (assuming A to be bottom left and B to be top) is a right angle, we can now work with trigonometry:
Sinx = opp/hyp and Cosx = adj/hyp which will give us the components of the vector. Substituting the known values into the equations and rearranging:
86Sin(35) = Opp = 49.3km/h
86Cos(35) = Adj = 70.4km/h
Therefore, the horizontal component (Ax) is 70km/h and the vertical component (Ay) is 49km/h
