1:A motor moving in water acts on two opposite
horizontal forces. One is the 3000 N force applied by the motor in
the forward direction, the other is the 1800 N force applied by the
water in the opposite direction. What is the acceleration of the
1000 kg engine? (g = 9.8 m / s ^ 2)
A)1,2 B) 0,2 C) 4,8 D) 1
2:The three blocks are on a frictionless plane as shown in the
figure. If m1 =...
1. Given a parallel circuit with a constant current source
containing resistors of different values, which statement is
true?
a. The voltage drop across the less resistive component is the
same the ones with higher resistance
b. Current is the same through each resistor
c. The voltage drop across the less resistive component is less
than the ones with higher resistance
d. None of the above
2. The conductance of a resistor decreases if the length of the
resistor is...
A constant force acts on a 600kg mass for 68s. The velocity of
the mass is 10m/s before the force is applied. Its final velocity
is 44m/s. What change in momentum does the force produce?
A voltage source and a current source both supply current on an
electrical system. So why do we call a voltage source a voltage
source? What is the difference between the two?
