Angle 1 . . . . . 14 parts
Angle 2 . . . . . 5 parts
Angle 3 . . . . . 11 parts
Total . . . . . . . . 30 parts
But the total of the angles in ANY triangle is always 180 degrees.
SO ... 180 degrees / 30 parts = 6 degrees per part.
Angle 1 . . . . . 14 parts x (6° / part) = 84°
Angle 2 . . . . . . 5 parts x (6° / part) = 30°
Angle 3 . . . . . 11 parts x (6° / part) = 66°
Check: Total . . . . . . . . . . . . . . . . . . 180° yay !
Answer:
The car exerts the same sized force on the bug as the bug exerts on the car.
Explanation:
Given that
Speed of car = 70 mph
Third law of Newton's
It state that when an object A apply force on the another object B then object B also apply the same force on the object A but in opposite direction .This is known as action reaction .In simple words every action and reaction.
By using the third law of concept,when car and a bug collides then car exerts the same sized force on the bug as the bug exerts on the car.
Answer:
Option A is correct
The electric potential at P1 is greater than that at P2, because r is smaller than 2r.
Explanation:
Electric potential at a point due to a particular charge (q) at r distance from that point is given as
V = kQ/r
where k = Coulomb's constant
For point P₁, the electric potential due to charge q, r distance away is given as
V₁ = kq/r
For point P₂, the electric potential due to charge q, (2r) distance away is given as
V₂ = kq/(2r)
This shows that the electric potential due to charge q at P1 is twice that experienced at P2 because of the same charge.
The electric potential at a point due to a particular only depends on the charge in question and the distance of that charge from that point.
If the charge and other parameters are constant, the electric potential at some distance away is inversely proportional to that distance. So, smaller r, indicates bigger electric potential.
Answer:
2.8 MW
Explanation:
There are 7 wind turbines in the wind farm as shown in the diagram. Thus, the energy output by one turbine is 1/7 if the total energy output. So, 19.6/7=2.8MW
