d) ≈ 0.87 m/s²
Explanation:Hi there !
Newton's second lawF = m×a => a = F/m
a = 59N/68kg
1 N = 1kg·m/s²
= (59kg·m/s²)/68kg
= 0.8676 m/s²
≈ 0.87 m/s²

a phosphorus atom needs to gain ---electrons to achieve a full octet
Answer:
Three (3).
Explanation:
The octet rule is a rule in chemistry that states that, chemical elements would either gain or loss electrons in their outermost shell in order to attain a stable electronic configuration i.e having eight (8) valence electrons in their outermost shell such as chemical elements found in group 8 (2-8-8) known as noble gas.
A phosphorus atom needs to gain three (3) electrons to achieve a full octet because the atomic number of phosphorus is 15 and as such it has the electronic configuration of 2-8-5 and needs three electron in order to become a stable element.

Arrange the following events in the mantle convection process. Use numbers 1-5.
a. Lithospheric plates move in the asthenosphere due to rising and sinking of
materials.
b. The decomposition of radioactive elements causes heat in the interior part of
the Earth
c. Heat slowly rises to the mantle and creates convection current.
d. Heat moves to the core.
e. The process repeats as cycle.
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
The proper and correct arrangement of events in the mantle convection process are:
1. The decomposition of radioactive elements causes heat in the interior part of the Earth.
2. Heat moves to the core
3. Heat slowly rises to the mantle and creates convection current.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process repeats as a cycle.
Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.
Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.
Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.
Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.
The proper and correct arrangement of events in the mantle convection process are:
1. Heat is caused in the interior part of the Earth due to the decomposition or decay of radioactive elements.
2. Heat moves to the core.
3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process is then repeated as a cycle.

Solve for the resultant displacement of the two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees
Answer:
The resultant of the vector is 6.63 km
Explanation:
Given;
vector A = 2.3 km 45°
vector B = 4.8 km 90°
The vectors in the x - direction is given by;
Aₓ = 2.3 km Cos 45° = 1.6263 km
Bₓ = 4.8 km Cos 90° = 0
The sum of the vectors in x -direction is given by;
∑X = 1.6263 km + 0 = 1.6263 km
The vectors in the y - direction is given by;
Ay = 2.3 km Sin 45 = 1.6263 km
By = 4.8 km Sin 90° = 4.8 km
The sum of the vectors in y -direction is given by;
∑Y = 1.6263 km + 4.8 km = 6.4263 km
The resultant vector is given by;
R = √(X² + Y²)
R = √[(1.6263)² + (6.4263)²]
R = 6.63 km
Therefore, the resultant of the vector is 6.63 km
The resultant displacement of the two vectors A and B is 6.63 Km and this can be determined by using the given data.
Given :
The two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees.
In order to determine the resultant displacement, first, determine the vector in x-direction:
[tex]\rm A_x=2.3cos45=1.6263 \;Km[/tex]
[tex]\rm B_x=4.8cos90=0 \;Km[/tex]
Now, the sum of the vectors is given by:
[tex]\rm \sum X=1.6263+0=1.6263\;Km[/tex]
In order to determine the resultant displacement, first, determine the vector in y-direction:
[tex]\rm A_y=2.3sin45=1.6263 \;Km[/tex]
[tex]\rm B_y=4.8sin90=4.8 \;Km[/tex]
Now, the sum of the vectors is given by:
[tex]\rm \sum Y = 1.6263+4.8=6.4263[/tex]
Now, the resultant vector is given by:
[tex]\rm R = \sqrt{X^2+Y^2}[/tex]
[tex]\rm R=\sqrt{(1.6263)^2+(6.4263)^2}[/tex]
R = 6.63 Km
The resultant displacement of the two vectors A and B is 6.63 Km.

What acceleration will all objects experience during their flights through the air (on Earth)?
Answer:
d
Explanation:
Answer:
9.8 m/s/s
Explanation:
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity

An object accelerates from rest to a velocity of 34 m/s
over a distance of 70 m. What was its acceleration?
Answer:
6.8m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 34m/s
Distance = 70m
Unknown:
To solve this problem we apply one of the motion equations;
V² = U² + 2aS
where V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance covered
Input the parameters and solve;
34² = 0² + 2 x a x 70
34² = 140a
a = 6.8m/s²
