Answer:
z
Explanation:
x repersents a new moon and the others repersent quarter moons
(x is a new moon because new moons are often the phase when the moon is close to earths sun)
A) 50 cm
B) 10000 cm/s
Explanation
Step 1
A)
If you know the distance between nodes and antinodes then use this equation:
then, let
now, replace to find the wavelength
so, the wavelength is
A) 50 cm
Step 2
The speed of a wave can be found using the equation
or velocity = wavelength x frequency,
then,let
replace and evaluate
so
B) 10000 cm/s
I hope this helps you
Answer: Find the answer in the explanation
Explanation: Given the Roman numeral and the representation
I. part of a coal-fired power plant
II. part of a nuclear power plant
III. part of a coal-fired power plant and part of a nuclear power plant
a.) Boiler : I
b.) Combustion chamber: I
c.) Condenser: I
d.) Control rod: II
e.) Generator: III
f.) Turbine: III
Toward the end processes part of both coal fire and nuclear power, they both make use of turbine and generator to generate electricity.
Answer:
The coefficient of kinetic friction between the crate and the floor can be calculated using the formula μ = Ff / N, where Ff is the frictional force, N is the normal force, and μ is the coefficient of kinetic friction.
In this case, the normal force is equal to the weight of the crate, which is 24 kg * 9.8 m/s2 = 235.2 N. The frictional force can be calculated using the formula Ff = μ * N, where μ is the coefficient of kinetic friction and N is the normal force.
If we substitute the values for N and Ff into the formula for the coefficient of kinetic friction, we get:μ = 53 N / 235.2 N = 0.225
Therefore, the coefficient of kinetic friction between the crate and the floor is 0.225.
Answer:
(A) It will take 22 sec to come in rest
(b) Work done for coming in rest will be 0.2131 J
Explanation:
We have given the player turntable initially rotating at speed of 
Now speed is reduced by 75 %
So final speed 
Time t = 5.5 sec
From first equation of motion we know that '
(a) Now final velocity 
So time t to come in rest 
(b) The work done in coming rest is given by
