Answer: 7.723s
Explanation:
given data:
initial velocity = 7.56 m/s.
friction = 0.0695.
change in velocity = 2.32 m/s
Solution:
[tex]ax = \frac{-Fk}{m}[/tex]
[tex]ax = \frac{-ukFN}{m}[/tex]
[tex]ax = \frac{-ukmg}{m}[/tex]
[tex]ax = -ukg[/tex]
[tex]recall = v0x +axt[/tex][tex].......eqn1[/tex]
[tex]t = \frac{vx - v0x}{ax}[/tex] [tex]........eqn2[/tex]
[tex]substitute[/tex] [tex]ax[/tex] [tex]into[/tex] [tex]eqn 2[/tex]
[tex]t = \frac{vx -v0x}{-ukg}[/tex]
[tex]t = \frac{2.32m/s - 7.56m/s}{-(0.0695)(9.80m/s^{2})}[/tex]
[tex]t= 7.723seconds[/tex]

Answer:
wet farts, JK its condensation.
The ionization energy of an atom is the energy required to remove an electron from the atom. In the Bohr model, the ionization energy equals the energy difference between the lowest energy level n = 1 , in which the electron is closest to the nucleus, and the energy level n = [infinity] , which has an infinite radius.
The question is incomplete, the complete question is;
The ionization energy of an atom is the energy required to remove an electron from the atom. In the Bohr model, the ionization energy equals the energy difference between the lowest energy level n = 1 , In which the electron is closest to the nucleus, and the energy level n oo, which has an infinite radius. Compared to the ionization energy of hydrogen, the energy required to remove the electron from singly ionized helium is O two times greater. O four times greater. eight times greater. O one-half as great. O one-fourth as great.
Answer:
four times greater
Explanation:
For a hydrogen atom, an ionization energy of 13.6 electron volts is required to eject its single electron from the lowest energy level all the way out of the atom.
The helium ground state contains only two 1s electrons. When one of these is removed, He^+ looks quite similar to H^+.
The energy required to remove the remaining helium electron should be; 4×(13.6eV)=54.4eV since the energy depends on the square of the nuclear charge.

Answer:
The y-axis should be labelled as W in Newtons (kg·m/s²)
Explanation:
The given data is presented here as follows;
Mass (kg) [tex]{}[/tex] Newtons (kg·m/s²)
3.2 [tex]{}[/tex] 31.381
4.6 [tex]{}[/tex] 45.1111
6.1 [tex]{}[/tex] 59.821
7.4 [tex]{}[/tex] 72.569
9 [tex]{}[/tex] 89.241
10.4 [tex]{}[/tex] 101.989
10.9 [tex]{}[/tex] 106.892
From the table, it can be seen that there is a nearly linear relationship between the amount of Newtons and the mass, as the slope of the data has a relatively constant slope
Therefore, the data can be said to be a function of Weight in Newtons to the mass in kilograms such that the weight depends on the mass as follows;
W(m) in Newtons = Mass, m in kg × g
Where;
g is the constant of proportionality
Therefore, the y-axis component which is the dependent variable is the function, W(m) = Weight of the body while the x-axis component which is the independent variable is the mass. m
The graph of the data is created with Microsoft Excel give the slope which is the constant of proportionality, g = 9.8379, which is the acceleration due to gravity g ≈ 9.8 m/s²
We therefore label the y-axis as W in Newtons (kg·m/s²)

Explain how scientist learned about the magnetic poles of the Earth.
If I drive 60 km/h and it takes me 3000 s to get to work, how far is my work
from my house? *
Answer:
Explanation: CONVERT km/h TO m/s
WE GET 16.67 M/S
THEN,
USE : speed= distance / time
16.67 = x / 3000
∴x = 50,000 m
or
∴x = 50 km
