Calculate the total resistance for a 650ohm , a 350 ohm , and a 1000 ohm resistor connected in series
Answers
Answer:
2000 ohms
Explanation:
Resisters in series just add.
Rt = R1 + R2 + R3
R1 = 650 ohm
R2 = 350 ohm
R3 = 1000 ohm
Rt = 650 + 350 + 1000
Rt = 2000 ohms.
The total effective resistance of several resistors in SERIES is just the sum of all the individual resistances.
So the effective resistance of 650Ω, 350Ω, and 1,000Ω in series is
Sum = (650Ω + 350Ω + 1,000Ω)
Sum = 2,000 ohms

'Frequency' is a word that often confuses some people ... for no good reason.
It just means "frequent-ness" or "often-ness" ... how often something happens.
The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.
So " 13 Hz " means 13 per second.
Here are examples of frequency:
-- 780 kilohertz (on your AM radio dial)
-- 98.7 Megahertz (on your FM dial)
-- 5.8 Gigahertz
-- twice a day
-- three per week
-- every 6 months

45 kg * 9.8 m/s^2 = 441 N.
Answer:
The force of a mass's weight is defined as its mass * acceleration due to gravity.
On Earth, g is about 9.8 m/s^2. This will be the acceleration due to gravity.
Then, 45 kg * 9.8 m/s^2 = 441 N.

Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.
What is meant by gas laws ?
Gas laws are defined as the laws that govern the properties of gases by determining the relationships between the pressure, volume and temperature of the gases.
Here,
Boyle's law is the gas law that governs the relationship between the pressure and volume of gases.
Boyle's law states that, for an ideal gas at a unit mass, the pressure of the gas is inversely proportional to the volume of the gas, at constant temperature.
P 1/V
PV = a constant
When the temperature of the gas is held constant.
Hence,
Boyle’s Law states that, when temperature is held constant, the pressure and volume of a gas are inversely proportional.

Since the kayakers speed is 1.5 meters per second relative to the stream, the kayakers velocity in meters per second relative to the shore should be its speed relative to the stream plus the stream's velocity relative to the shore. This is 1.5m/s + 3.0m/s which is equal to 4.5 meters per second (m/s).
Final answer:
The kayaker's speed relative to the shore is calculated by adding the stream's speed (3.0 m/s) and the kayaker's speed relative to the stream (1.5 m/s), which results in 4.5 m/s.
Explanation:
In this scenario, the kayaker's total velocity, or speed relative to the shore, is the vector sum of the kayak's velocity relative to the water and the water's velocity relative to the shore. This principle reflects how velocities combine in Newtonian mechanics. Given that the stream's velocity is 3.0 meters per second and the kayaker's velocity relative to the stream is 1.5 meters per second, we add these velocities together to get the kayaker's velocity relative to the shore.
Therefore, the kayaker's speed relative to the shore is 4.5 meters per second. This sum is based on the principle that when moving downstream, the stream's velocity (its speed in a particular direction) augments the velocity of the kayak.
