Acceleration is the rate of the change in velocity.
The answer would be the rate at which velocity changes.
the position that has least kinetic energy is option D
Answer:
I would need more electrons 1.3125 10¹⁰ electrons
Explanation:
Static electricity is formed by induced charges in each part of the system, so the net charge does not change.
Let us analyze the situation presented, if the carpet acquires a positive charge, so that it does not alter the total charge in man, it should acquire a negative charge, to have a net negative charge I would need more electrons that have a negative charge.
We can know the number of electrons by a rule of proportions, if an electron has a charge of 1.6 10-19 C for a charge of 2.15 10-9 C how many electrons are needed
# = 2.15 10⁻⁹ /1.6 10⁻¹⁹
# = 1.3125 10¹⁰ electrons
The number is very high for which we will not worry about rounding since the number of electrons must be an integer
Answer:
In parallel circuits all components have the same voltage. In series circuits all components have the same current.
Explanation:
Voltage in a circuit is akin to pressure in water, while current is akin to flow in water.
Voltage and current are related to resistance by Ohm's law:
Where:
V: voltage
I: current
R: resistance
In a parallel circuit all the terminals of one side of the devices are connected together. This is known as a node. Nodes have a certain voltage. Devices connected in parallel will have one node on each side, and each node will have it's own voltage. Current will flow through each component independently depending on their resistance, so it is not the same for all of them.
In a series circuit components are connected one after the other, the current that flows through one must continue and flow through the next, so they all have the same current. But since they might have different resistances they might have different voltage differences between their terminals.
Parallel connection is useful when you have devices that require a specific voltage, such as household appliances. All wall power outlets are connected in parallel.
Series connection is useful when you want to control current. When you use a LED you must be careful not to apply an overcurrent, so a series resistor is commonly used to limit the current.
In solid and liquid the matter can occupy the 90 in³ and 157.1 in³ volume.
The matter in gaseous state can be expanded to occupy the volumes of the container.
<h3>
Volume of each of the container</h3>
The volume of each of the container is calculated as follows;
<h3>Volume of the rectangular container</h3>
V = 5 in x 6 in x 3 in
V = 90 in³
<h3>Volume of the cylindrical container</h3>
V = πr²h
V = (π)(2.5 in)²(8 in)
V = 157.1 in³
<h3>Volume of the matter</h3>
Vm = 3 in x 4 in x 5 in
Vm = 60 in³
<h3>Matter in solid and liquid state</h3>
Matter has fixed volume in solid and liquid state.
In solid and liquid the matter can occupy the 90 in³ and 157.1 in³ volume.
<h3>Matter in gaseous state</h3>
Matter has no definite volume in gaseous state.
The matter in gaseous state can be expanded to occupy the volumes of the container.
