Answer:
sorry I don't know I am too bad a t this coz I am only at class 7
Answer:
Q = 8 μC
Explanation:
The relation between voltage, capacitance and charge can be expressed using the following rule:
Q = C * V
where:
Q is the amount of charge that we want to calculate
C is the capacitance = 4 * 10⁻⁶ F
V is the voltage applied = 2 V
Substitute with the givens in the above equation to get the amount of charge as follows:
Q = C * V
Q= 4 * 10⁻⁶ * 2
Q = 8 * 10⁻⁶ Coulumb
Q = 8 μC
Hope this helps :)
Displacement isn't total distance traveled, it's the distance from the original starting point. So the 70 meters South in addition to the 30 meters South would decrease the distance to the North. It would then, instead of being 100 meters North and 100 meters South, there would be zero displacement. Then you take 50-20 to get 30 meters West. Your final displacement is 30 meters.
For the lengths of its sides
As a scalene triangle (from the Greek σκαληνός "unequal"), if all its sides have different lengths (in a scalene triangle there are no two angles having the same measure)
For its angles
obtuse triangle: if one of its interior angles is obtuse (greater than 90 °); the other two are acute (less than 90 °).
Answer:
Explanation:
This is the formula for centripetal acceleration in terms of the tangential velocity (v) and the radius of the circular motion (r). The expression for the acceleration is already given, so simply type it as shown:
For the velocity (v) multiply by "r" both sides and then use the square root to solve for v:
For the radius multiply both sides by r and then divide both sides by the acceleration (a) in order to isolate r completely:
