I can't find the attached circuit.
Maximum power transfer occurs when the load impedance
is equal to the internal impedance of the power source.
Answer:
(d) −7 C
Explanation:
Like charges attracts and unlike charges repel. When the three charges are are agitated, the +3 C and +4 C will repel to give of +7 C. To create a balance in the system, the third charge will -7 C to give an algebraic sum of zero in the system.
Answer:
Part a)
Part b)
So this speed is independent of the mass of the rider
Explanation:
Part a)
By force equation on the rider at the position of the hump we can say
now we will have
now we have
Part b)
At the top of the loop if the minimum speed is required so that it remains in contact so we will have
at minimum speed
So this speed is independent of the mass of the rider
Answer:
D-Andes Mountains
Explanation:
Convergent boundaries are places where two tectonic plates are moving against eachother and collide, causing faults and mountains, from the options the only feature that us caused by convergent plate boundaries is the Andes Mountains that are created by the collision of the Nazca plate and the Southamerican plate, this collision created the Andes Mountains in Peru.
