Force = mass * acceleration
F = ma
Given m = 10 kg, F = 30 N;
F = ma
30 = 10a
Solving for a:
a = 3 m/s^2
The acceleration is 3 meters per second squared.
The smallest unit that makes up matter is an atom!
Answer:
θ = 34.77°
Explanation:
From diffraction equation:
where,
m = order of diffraction
λ = wavelength of light used
d = slit separation
θ = angle
Therefore, for initial case:
m = 2
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = ?
θ = angle 20°
Therefore,
Now, for the second case:
m = 5
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = (1.5)(3.5 x 10⁻⁶ m) = 5.26 x 10⁻⁶ m
θ = angle = ?
Therefore,
<u>θ = 34.77°</u>
Answer: Length axis f= 114.3 Hz, Width axis f=228.67 Hz
Explanation:
We are given that,
Length of tub= 1.5 m
Width of tub= 0.75 m
Sound speed= 343 m/s
Now, we are also given shower is closed.
So, frequency is given as:
f=
For length axis
Put v= 343 m/s, m=1 and L=1.5 m
f= 1 *
f= 114.3 Hz
For next resonant frequency, m=2
f= 2*
f= 228.67
For width axis
Put v= 343 m/s, m=1 and L= 0.75 m
f= 1*
f= 228.67 Hz
For next frequency, m=2
f= 2*
f= 457.34 Hz
Answer:
After we satisfy our basic needs, they no longer serve as motivators and we can begin to satisfy higher-order needs. Maslow organized human needs into a pyramid that includes (from lowest-level to highest-level) physiological, safety, love/belonging, esteem, and self-actualization needs.
