Answer:
C. and D.
C. becuase A is heavier so it will land first
Answer:
False
Explanation:
The current flowing through a circuit can be computed by using Ohm's law:
where
V is the voltage of the battery
Req is the total resistance of the circuit
Let's now compare the two situations. Let's call R the resistance of each resistor (since they are identical, they have same resistance, R)
- Series configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(1)
- Parallel configuration: in this case, the total resistance of the circuit is given by
So the current through the circuit is
(2)
By comparing (1) and (2), we see that the current in the parallel configuration is greater than in the series configuration:
therefore, the correct answer is false.
So I’m gonna answer the first question on the second page:
For P the force is friction and for Q the force is forward thrust resultant force
Answer:
2.10 N
Explanation:
Draw a free body diagram of the toy. There are four forces:
Weight force mg pulling down,
Normal force N pushing up,
Friction force F pushing left,
Applied force 4.63 N pulling at an angle of 63.0°.
Sum of the forces in the x direction:
∑F = ma
4.63 N cos 63.0° − F = 0
F = 2.10 N
Answer:weak nuclear
Explanation:
There weak nuclear force is responsible for allowing carbon-14 to become stable
