Answer:
a) h / h₀ = 1,682
, b) h / h₀ = 1.11
, c) h / h₀ = 2.07
Explanation:
For this exercise let's look for the growth equation, as they indicate that it is exponential
h = h₀ 
The initial height is 9 ”, so the constant
h₀ = 9”
Let's use the given values
h = 15.1655”
t = 5 days
h / h₀ =
α = 1 / t ln h / h₀
α = 1/5 ln (15.1655 / 9)
α = 0.104
h = 9 e^{0.104 t}
a) the growth factor is the relationship between the initial value and the current value
h / h₀ = 
h / h₀ = 1,682
b) for t = 1 day
h / h₀ = 
h / h₀ = 1.11
c) for t = 7 days
h / h₀ = e^{0.104 7}
h / h₀ = 2.07
Conservation of momentum: total momentum before = total momentum after
Momentum = mass x velocity
So before the collision:
4kg x 8m/s = 32
1kg x 0m/s = 0
32+0=32
Therefore after the collision
4kg x 4.8m/s = 19.2
1kg x βm/s = β
19.2 + β = 32
Therefore β = 12.8 m/s
Answer:
ν = 5.45 x 10¹⁴ Hz
Explanation:
given,
wavelength of light = 550 nm
= 550 x 10⁻⁹ m
speed of light = 1.96 x 10⁸ m/s
speed of sound = 3 x 10⁸ m/s
frequency of the light = ?
we know.
frequency of the light in the liquid is same as the frequency of the light in the air.
ν is the frequency of light
ν = 5.45 x 10¹⁴ Hz
Hence, the frequency of light in the liquid is equal to ν = 5.45 x 10¹⁴ Hz
Answer:
mature man means giving up the need to conquer and vanquish and being okay with letting others get their way.
Explanation:
Answer:
<em>F</em> = <em>0</em>
Explanation:
This problem can be solved by using the equation for the force produced by a magnetic field over a charge
<em>F</em> = q<u><em>v</em></u> X <em>B</em>
That is, the cross product between velocity and the magnetic field.
In this case, v is in the negative z-direction <em>v</em> = -v k^,
and the magnetic field is in the positive z-direction <em>B</em> = z k^
Hence, the cross product is
F = q<em>v </em>X <em>B</em> = 0i^ - 0j^ + 0k^ = <em>0</em>
In this case the net force is zero due to both velocity and magnetic field vectors are in the z-direction
