given,
door width = 1 m
mass of = 15 Kg
Mass of bullet = 0.01 Kg
speed of the bullet = 400 m/s
a) from conservation of angular momentum
Answer:
option B
Explanation:
The correct answer is option B
Effective capacity is the capacity of a firm to achieve the given target will all the constraints .
Effective capacity of an company can be calculated by actual capacity divided by the efficiency of the company.
it can be explained by an example
Assume the capacity of company to produce toy is 49 per hours and the efficiency of the production is 70 %
so the effective capacity will be equal to 49/0.7 = 70
hence, effective capacity will be 70
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 !
The answer is 200, 200 tennis balls would be in 8 bags if they each held 25.
Answer:
voltage measured by the voltmeter = (E × RV)/(r + RV)
Explanation:
The circuit diagram for this description is presented in the attached image.
The internal resistance of an emf source is modelled to be in series with the source.
Therefore, the end product is a circuit with the battery in series connection with the internal resistance and resistance of the volunteer. The voltage picked up by the volunteer is the voltage across resistor RV.
Total resistance in the circuit = (r + RV) ohms (since both resistors are in parallel)
Current produced by the emf source = E/(Total resistance) = E/(r + RV)
The voltage across resistor RV = current flowing through this resistor × its resistance.
Since all the circuit elements are in series with each other, same current, E/(r + RV) flows through them all
Voltage across RV = voltage measured by the voltmeter = [E/(r + RV)] × RV = (E × RV)/(r + RV) = (E.RV)/(r + RV)
