Correct displacement 4km south,2 km north, 5km south, and 5 km north
babymother [125]

Answer:

2 km due south.

Explanation:

We need to find the displacement of 4km south,2 km north, 5km south, and 5 km north.

Let south is negative direction and north is positive direction.

The shortest path covered by an object is called its displacement.

D = -4+2-5+5

D = -2 km

So, the displacement is 2 km and it is in south direction.

assuming that the seafloor is spreading at a rate of 1.3cm/yr, calculate how long it took africa's west coast to move 2400 kn aw
Verdich [7]

Answer: 184,615,384.6 years

Explanation:

This problem can be solve by the following equation:

V=\frac{d}{t} (1)

Where:

V=1.3 \frac{cm}{year} \frac{1 km}{100000 cm}=0.000013 \frac{km}{year} is the spreading rate of the seafloor, its velocity

d=2400 km is the distance the Africa's west coast moved at this rate

t is the time it took to the coast to move the descibed distance

Isolating t from (1):

t=\frac{d}{V} (2)

t=\frac{2400 km}{0.000013 \frac{km}{year}} (3)

Finally:

t=184,615,384.6 years This is the time it took to the Africa's west coastto  move away from the Mid atlantic ridge.

Projectile <br> SHOW WORK<br> WILL MARK BRANLIEST <br> (Draw Picture and Label)
m_a_m_a [10]

a) The horizontal distance covered by the projectile is 600 m

b) The projectile reaches its maximum height after 3.00 s

c) The altitude of the highest point is 44.1 m

Explanation:

a)

The motion of the projectile consists of two independent motions:  

- A uniform motion (constant velocity) along the horizontal direction  

- A uniformly accelerated motion, with constant acceleration (acceleration of gravity) in the downward direction  

In this part A, we just need to analyze the horizontal motion. We know that:

  • The projectile travels horizontally with a constant velocity ov v_x = 100 m/s
  • The total time of flight of the projectile is t=6.00 s

Therefore, the horizontal distance covered by the projectile is given by

x=v_x t

And substituting, we find

x=(100)(6.0) = 600 m

b)

For this part, we need to analyze the vertical motion of the projectile.

First, we want to find the initial vertical velocity. We can do it by using the equation for the vertical displacement:

s=u_y t + \frac{1}{2}at^2

where:

u_y is the initial vertical velocity

a=g=-9.8 m/s^2 is the acceleration of gravity (negative because it is downward)

t is the time

s is the vertical displacement

We know that the total time of flight is t = 6.00 s: this means that when t=6, the projectile returns to its initial vertical position, so s = 0. Substituting and solving for u_y, we get

u_y = - \frac{1}{2}at=-\frac{1}{2}(-9.8)(6)=29.4 m/s

The vertical velocity then as a function of t is given by

v_y = u_y + at

And at the maximum height, it becomes zero: v_y = 0. Substituting and solving for t, we find the time at which the projectile reaches the maximum height:

t=-\frac{u_y}{a}=-\frac{29.4}{-9.8}=3.00 s

c)

To find the altitude of the highest point in the path, we use again the equation:

s=u_y t + \frac{1}{2}at^2

where

u_y = 29.4 m/s is the initial vertical velocity

t = 3.00 s is the time at which the projectile reaches the highest point

a=g=-9.8 m/s^2 is the acceleration of gravity

Substituting the values, we find

s=(29.4)(3.00)+\frac{1}{2}(-9.8)(3.00)^2=44.1 m

So, the highest point is at 44.1 m above the ground.

Variations in the reactive properties of different organic molecules are most closely associated with _____.
azamat

Answer:

the presence or absence of functional groups

Explanation:

The functional group is the group of atoms that characterize a chemical function and that have well-defined characteristic properties.

In organic chemistry, the functional group is a set of submolecular structures, characterized by a specific elementary connectivity and composition that confers specific chemical reactivity to the molecule that contains them. These structures replace the hydrogen atoms lost by saturated hydrocarbon chains. Aliphatic, or open chain, groups are usually represented generically by R (alkyl radicals), while aromatic ones, or derivatives of benzene, are represented by Ar (aryl radicals).
