A student shakes the end of
a rope
with
frequency of 1.5 Hz, causing waves with a
wavelength of 0.8 m to travel along the rope.
What is the velocity of the waves?
Answer:
1.2m/s
hope this helps!
The required velocity of the waves is 1.2 meters per second.
What is wavelength?Wavelength is a fundamental property of waves, including electromagnetic waves like light and radio waves, as well as other types of waves, such as sound waves or water waves.
Here,
The velocity of a wave can be calculated using the equation:
Velocity = frequency × wavelength
In this case, the frequency is 1.5 Hz and the wavelength is 0.8 m. Therefore, the velocity of the waves is,
Velocity = 1.5 Hz × 0.8 m = 1.2 m/s
So the velocity of the waves is 1.2 meters per second.

If I have an unknown quantity of gas at a pressure of 8.5 atm, a volume of
11.6 liters, and a temperature of 43 °C, how many moles of gas do I have?
Answer:
3.802 moles
Explanation:
P = 8.5 atm
V = 11.6 liters
R = 0.08206
T = 316 K (273 + 43)
PV = nRT
(8.5)(11.6) = n(0.08206)(316)
---> n = 3.802 moles

How many moles of gas are in a 22.4 L container at 1 atm of pressure and 89℃?
How many moles of gas are in a 16.7 L container at 1 atm of pressure and 273.15 K?
Answer:
1.29 moles
0.753 moles
0.745 moles
Explanation:
PV=nRT
n=PV/RT
n=(1)(34.2)/(0.0821)(323.7)
n=1.29
n=PV/RT
n=(1)(22.4)=(0.0821)(362.15)
n=0.753
n=PV/RT
n=(1)(16.7)/(0.0821)(273.15)
n=0.745

The edge effect in habitats are caused by:
A. habitat fragmentation
B. biological magnification
C. eutrophication
D. destruction of habitat
The edge effect in habitats is caused by habitat fragmentation. Therefore, option A is correct.
Habitat fragmentation refers to the process by which large, continuous habitats are divided into smaller, isolated fragments due to human activities or natural events. It occurs when natural landscapes are altered or disrupted. It results in the fragmentation of once-continuous habitats into smaller patches.
This fragmentation can happen through various means, such as the construction of roads, urban development, agriculture, deforestation, or natural events like wildfires or floods.

In a nuclear power plant, uranium atoms ______
A. Combine and give off heat energy
B. Split and give of heat energy
C. Burn and give of heat energy
D. Split and give off electrons
Answer:
All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.

Two parallel plates of area 7.34 x 10^-4 m^2 have 5.83 x 10^-8 C of charge placed on them. A 6.62 x 10^-6 C charge q1 is placed between the plates. What is the magnitude of the electric force on q1? Hint: How is force related to the field? (Unit = N)
Answer:
* if the two plates have the same charge sign F_net = 0
*if one plate is positive and the other is negative F_net = 59.4 N
Explanation:
The electric field created by a parallel plate is
E = [tex]\frac { \sigma }{2 \epsilon_o }[/tex]
where sigma is the charge density
σ = Q / A
we substitute
E = [tex]\frac{Q}{A \ 2 \epsilon_o }[/tex]
E = [tex]\frac{ 5.83 \ 10^{-8} }{7.34 \ 10^{-4}\ 2 \ 8.5 \ 10^{-12} }[/tex]
E = 4.487 10⁶ N / C
the electric force is
F = E / q
in this force it is a vector, so if the charges are of the same sign they repel and if they are of the opposite sign they attract. In this case, the test load is between the two plates that have the same load sign, so the forces are in the opposite direction.
* if the two plates have the same charge sign
F_net = F₁ - F₂
F_net = q (E₁ -E₂)
since the electric field does not depend on the distance
E₁ = E₂
in consecuense
F_net = 0
In a more interesting case
*if one plate is positive and the other is negative
F_net = F₁ + F₂
F_net = q (E₁ + E₂) = 2 q E₁
F_net = 2 6.62 10⁻⁶ 4.487 10⁶
F_net = 59.4 N
net force goes from positive to negative plate

Sound travels at about 360 meters/sec. What is the wavelength of sound with a
frequency of 1500 Hz?
Answer:
0.24 m
Explanation:
Given:
Wave velocity ( v ) = 360 m / sec
Frequency ( f ) = 1500 Hz
We have to calculate wavelength ( λ ):
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > λ = v / f
Putting values here we get:
= > λ = 360 / 1500 m
= > λ = 36 / 150 m
= > λ = 0.24 m
Hence, wavelength of sound is 0.24 m.
Light is created by the motion of charged particles.
