An airplane flies with a velocity of 750. kilometers
per hour, 30.0° south of east. What is the
magnitude of the eastward component of the
plane's velocity?
A. 866 km/h
B. 650. km/h
D. 375 km/h
C. 433 km/h
The magnitude of velocity in east direction will be 650 N approximately.
What is velocity ?
velocity is given by the change in distance by the object with respect to change in time. It is a vector quantity and having S.I unit as m/s.
Here it is given that magnitude of velocity is 750 N and making an angle of 30 degree with x axis in counterclockwise direction as shown in figure below :
Now resolving and writing magnitude of velocity V in x and y direction respectively :
[tex]\begin{aligned}Vcos\theta&= 750 cos30^{o}=650 \:m/s\\Vsin\theta&= 750sin30^{o}= 375 m/s\end{aligned}[/tex]
It should be noted that [tex]vsin\theta[/tex] is acting in negative y direction.
Therefore, the magnitude of velocity in east direction is 650 m/s

An airplane during departure has a constant acceleration of 3 m / s².
a. What is the speed that the plane reaches in 4 s?
b. If the plane passes at a flight point of
at a speed of 20 m / s, what is the speed 8 s later?
Constant acceleration of plane = 3m/s²
a) Speed of the plane after 4s
Acceleration = speed/time
3m/s² = speed/4s
S = 12m/s
The speed of the plane after 4s is 12m/s.
b) Flight point will be termed as the point the plane got initial speed, u, 20m/s
Find speed after 8s, v
a = 3m/s²
from,
a = v - u
t
3 = v - 20
8
24 = v - 20
v = 44m/s
After 8s the plane would've 44m/s speed.

Answer:
answer is c
Explanation:
although the pivot exerts a force on the ruler it does not exert a torque with respect to the pivot point. why not?
Answer:
The situation is not shown, however if one calculates torques about the pivot point, then the pivot point itself exerts no torque because the force applied by the pivot point exerts zero torque because Fp * L = 0 where L = 0 in this case.
If one wants to calculate torques about, say, the end of the ruler then one would need to calculate the torque applied by the pivot point.

When two atoms bond chemically it is because of the interaction between
A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom.
Pls hurryyyy!!!
Answer:
Explanation:D
When two atoms bond chemically it is because of the interaction between the valence electrons in each atom because only the valence electrons of an atom are responsible for the chemical activity.
Therefore the correct answer is option D.
What is a chemical reaction?A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products.
Because only an atom's valence electrons are responsible for the chemical activity and because the quantity of valence electrons indicates an atom's valency,
Valency is a highly important requirement for the chemical reactivity of any element, two atoms connect chemically as a result of their contact.
Thus, the correct answer is option D.

Why do some substances dissolve in water, but other substances do not?
Answer:
It has to do with the polairity of said molelule. If you have vegetable oil, for example, it will not disolve in water because the oil is a non-polar compound, unlike water which is polar. The bond dipoles and differences in electronegetivity in the molecule results in this.
