Answer:
1 3/5*2/3=6/15
2 (3/5*2/3)+(2/3*5/6)+(3/5*5/6)=Ans
3 same as 2 i think
4 3/5+2/3+5/6=ans
5 (1-3/5)*(1-2/3)*(1-5/6)
Explanation
1 means x and y... for such a we multiply the probabilities
2 means x and y or x and z or y and z9 multiply ands add ors
3 i think it is same as 2
4 for this you have to negate the probabilities of killing to find that of not killing. Since it will be x and y and z, you multiply the final probabilities

Answer: d
One thirty-sixth of
Explanation: Gravitational field or gravitational field strength obeys the inverse square law. The gravitational field is inversely proportional to the square of the earth distance. That is,
g = Gm/r^2
Where r = distance.
If weather satellite is placed in orbit six times farther away from the earth's centre, gravitational field will be one thirty-sixth of its initial value.
Therefore, the gravitational field experienced by the satellite in orbit is one thirty-sixth of the field that it experienced on the ground.
Answer: Inertia
Explanation: Objects to stay in motion or at rest unless there is an external unbalanced force aced upon the object.
- The angular acceleration of the wheel approximately <u>-0.76 rad/s² or proportionally as deceleration approximately 0.76 rad/s</u>.
- It need approximately <u>14.474 s</u> to come to rest.
<h2>Introduction</h2>
Hi ! I will help you to discuss about Proportionally Changes in Circular Motion. The analogy of proportionally changes in circular motion is same as the analogy of proportionally changes in direct motion. Here you will hear again the terms acceleration and change in speed, only expressed in the form of a certain angle coverage. Before that, in circular motion, it is necessary to know the following conditions:
- 1 rotation = 2π rad
- 1 rps = 2π rad/s
- 1 rpm =
=
<h2>Formula Used</h2>
The following equations apply to proportionally changes circular motion:
<h3>Relationship between Angular Acceleration and Change of Angular Velocity </h3>

With the following conditions:
= final angular velocity (rad/s)
= initial angular velocity (rad/s)
= angular acceleration (rad/s²)- t = interval of the time (s)
<h3>Relationship between Angular Acceleration and Change of

(Angle of Rotation) </h3>

Or

With the following condition :
= change of the sudut (rad)
= angular acceleration (rad/s²)- t = interval of the time (s)
= final angular velocity (rad/s)
= initial angular velocity (rad/s)
<h2>Problem Solving</h2>
We know that :
= final angular velocity = 0 rad/s >> see in the sentence "in the process of coming to rest."
= initial angular velocity = 11 rad/s
= change of the sudut = 80.0 rad
What was asked :
= angular acceleration = ... rad/s²- t = interval of the time = ... s
Step by step :
= ... rad/s²










<h3>Conclusion</h3>
So :
- The angular acceleration of the wheel approximately -0.76 rad/s² or proportionally as deceleration approximately 0.76 rad/s.
- It need approximately 14.474 s to come to rest.
Answer: Please see below as the answer is self-explanatory.
Explanation:
The Newton's 3rd law, in simple words, explains, that for any force exerted on an object by another one, there exists a reaction from the object acted upon, which consists in another force, that is of equal value that the one is being exerted on it, but in the opposite direction, and is acting on the the other object.
So, Newton's 3rd Law says that for any pair of objects interacting, there is a pair of forces, equal and opposite, that each of them exerts on the other.
It is very important to understand, that in any free body diagram, it must be showed only one of these forces, the reaction that the other object is exerting on the object for which we are drawing the FBD, not the two forces, as the another one is external to the other object.
One example for this is the normal force, the gravity force, etc.
