Amplitude: 30 cm; wavelength 110cm.
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.
Answer:
Maximum height, h(t) = 95 meters
Explanation:
A ball travels on a parabolic path in which the height (in feet) is given by :
.............(1)
Where
t is the time after launch
We need to find the maximum height of the ball in feet. For maximum height,
t = 2
Put the value of t in equation (1) as :
h(t) = 95 meters
So, the maximum height of the ball is 95 meters. Hence, this is the required solution.
