Its B- Ground, just took the test
F=ma
Force is 50N. Acceleration is 25 m/s^2.
50N=m*25 m/s^2
Divide both sides by 25.
mass=2 kg
Answer:
Explanation:
Impedence of the circuit = peak voltage / peak current
= 5.8 / 51 x 10⁻³
= 113.725 ohm.
1 / wC =113.725
w = 1 / (113.725 x 22 x 10⁻⁹ )
= 10⁹ / 2.5 x 10³
=10⁶ / 2.5
40 x 10⁴
frequency n = 40 x 10⁴ / 2 x 3.14
6.37 x 10⁴ Hz.
b ) charge on the capacitor = 1 C
V = Q / C
= Charge / capacitor
= 1 / 22 x 10⁻⁹
4.54 x 10⁷ V.
Answer:
1.8m
Explanation:
Let the Elastics of the steel ASTM-36 
The strain of the bar when subjected to 150 MPa is
Therefore, if the bar elongates by 1.35 mm, then the original length L would be:
or 1.8m
Answer:
0
Explanation:
Defining velocity :
Velocity is a vector which is the ratio of a person's total displacement with time.
Displacement, in simple terms refers to the distance between an individual's initial position to his final position.
Man's initial position = House
After all his navigation and points covered irrespective of the distance ;
Final position = House
Hence, we can conclude that the man's Displacement is ;
Final position - Initial position = 0
Hence,
Velocity = Displacement / time taken
Velocity = 0 / 3
Velocity = 0
