Speed=100m/sec Frequency=10 Hz Wavelength=?

Physics
1 answer:
elena-14-01-66 [18.8K]3 years ago
4 0

Answer:

Wavelength = 10 m

Explanation:

Given:

Speed = 100 ms^{-1}

Frequency = 10 Hz = 10 s^{-1}

To find : Wavelength = ?

We know that the relationship between wavelength λ, frequency f and speed v is given by the equation

    v = fλ

Therefore wavelength λ = v/f

                                        = 100 ms^{-1} / 10 ms^{-1}

                                        = 10 m

Hence wavelength = 10 m

how much energy is needed to heat 2kg of cooking oil with a specific heat capacity of 2000j/kg°c from 20°c to 120°c​
mash [69]

Answer:

400kj

Explanation:

h =mass × specific heat capacity × change in temperature

= 2×2000×[120-20]

=2×2000×100

=400000j

=400kj

A 51 kg woman skis down a hill and her kinetic energy is 9.96e4 j. What is her speed?
arlik [135]

Kinetic energy of woman is given as

KE = 9.96 \times 10^4 J

mass of woman is given as

m = 51 kg

now we will have

KE = \frac{1}{2}mv^2

9.96 \times 10^4 J = \frac{1}{2}(51) v^2

v^2 = \frac{9.96 \times 10^4}{25.5}

v^2 = 3.91 \times 10^3

v = 62.5 m/s

What are the different advantages of a) the series vs. b) the parallel circuits? The resistors could be replaced with lightbulbs
Molodets [167]

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:

V = R*I

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.
