Answer:
A series circuit
Explanation:
Resistors can be connected in two different configurations:
- Series: all resistors are connected along the same path. In this case, the current flowing through each resistor is the same, while the potential difference across each resistor is different. The total resistance of the circuit for resistor in series is given by
- Parallel: each resistor is connected to the same batter through a different branch. In this case, the potential difference across each resistor is the same, while the current flowing through each resistor is different. The total resistance of the circuit for resistors in parallel is given by
In this problem, we have resistors all connected in the same path, so they are connected in a series configuration.
Explanation:
A double replacement reaction is a reaction in which two different compounds are mixed together and both their cations and anions get exchanged with each other respectively.
When potassium bromide reacts with silver nitrate then it results in the formation of potassium nitrate and silver bromide.
The chemical reaction equation is as follows.
In order to determine the acceleration of the block, use the following formula:
Moreover, remind that for an object attached to a spring the magnitude of the force acting over a mass is given by:
Then, you have:
by solving for a, you obtain:
In this case, you have:
k: spring constant = 100N/m
m: mass of the block = 200g = 0.2kg
x: distance related to the equilibrium position = 14cm - 12cm = 2cm = 0.02m
Replace the previous values of the parameters into the expression for a:
Hence, the acceleration of the block is 10 m/s^2
