Answer:

BMI = 20.98 [kg/m^2]; Normal or Healthy Weight

Explanation:

Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. Therefore we must convert the height from centimeters to meters.

BMI = 68 / (1.8)^2

BMI = 20.98 [kg/m^2]

BMI Weight Status

Below 18.5                   Underweight

18.5 – 24.9                   Normal or Healthy Weight

25.0 – 29.9                   Overweight

30.0 and Above           Obese

So the weight status is Normal or Healthy Weight

Answer:

103.5 meters

Explanation:

Given that a stunt person has to jump from a bridge and land on a boat in the water 22.5 m below. The boat is cruising at a constant velocity of 48.3 m/s towards the bridge. The stunt person will jump up at 6.45 m/s as they leave the bridge.

The time the person will jump to a certain spot under the bridge can be calculated by using the formula below:

h = Ut + 1/2gt^2

since the person will fall under gravity, g = 9.8 m/s^2

Also, let assume that the person jump from rest, then, U = 0

Substitute h, U and g into the formula above

22.5 = 1/2 * 9.8 * t^2

22.5 = 4.9t^2

22.5 = 4.9t^2

t^2 = 22.5/4.9

t^2 = 4.59

t = [tex]\sqrt{4.592}[/tex]

t = 2.143 seconds

From definition of speed,

speed = distance /time

Given that the boat is cruising at a constant velocity of 48.3 m/s towards the bridge, substitute the speed and the time to get the distance.

48.3 = distance / 2.143

distance = 48.3 * 2.143

distance = 103.5 m

Therefore,  the boat should be 103.5m away from the bridge at the moment the stunt person jumps?

Group of answer choices.

A. Cue overload principle.

B. Recall effect.

C. Encoding specificity principle.

Answer:

C. Encoding specificity principle

Explanation:

Memory can be defined as the ability of an individual to assimilate information, store this information and recall or retrieve it later in the future.

Generally, there are basically three (3) processes associated with memory and these include;

1. Encoding of data: it involves the process of getting data (informations) into our memory.

2. Storage of data: it simply involves the process of storing and maintaining data (informations) in our memory.

3. Retrieval of data: it involves the process of getting or retrieving data (informations) out of our memory.

According to cognitive psychologists, the process of retrieving or getting data out of our memory can fail or be successful depending on a number of factors such as situation, condition, or context.

An encoding specificity principle states that an individual's memory is enhanced and improved when data (informations) made available during the process of encoding is also available at retrieval (decoding).

For instance, if students were tested in the same classroom where they were taught, there is a better chance of retrieving or recalling informations than testing them in a different classroom all together.

Hence, an encoding specificity principle suggest that when the conditions present during the encoding of information into memory are made available during retrieval, this would improve and enhance the recall of such informations.

Answer: There are many problems associated with digitized DNA storage.

Explanation:

The cost of encoding the DNA data is high and lot of working efficiency is required for the same. The encoding process requires a considerable amount of time and encoding is slow. It takes about 400 bytes per second. This is done in a silicon memory chip. The process is millions of times slower.

Answer:

Inelastic Collision

Explanation:

My , oh my , what a pervy question.

Two players collide with each other (I dont think they stick together though) and what happens during collision of two bodies is that after the collision , they get pushed apart due to the momentum generated (Newton 2nd law) during collision because they collide with such heavy forces.

Also this is Linear motion (straight line motion).  

The collision is inelastic collision because both players hit each other (stick?) with different velocities.

Linear motion and Inelastic collision.

Answer:

Mass, m of the student is 50kg.

Explanation:

Given the following data;

Weight of student = 490N

Acceleration due to gravity = 9.8m/s

Weight is the product of the mass of an object or body multiplied by gravity.

Mathematically, weight is;

[tex] W = mg[/tex]

Where;

W represents the weight of a body measured in Newton.

m represents the mass of a body measured in kilograms.

a represents acceleration due to gravity measured in metre per seconds.

[tex] m = \frac{W}{g}[/tex]

[tex] m = \frac{490}{9.8}[/tex]

Mass, m = 50kg.

Therefore, the mass of the student is 50kg.

Answer:

The planes’ acceleration from A to B is 500m/s^2

Explanation:

Given that the initial velocity u is 8000m/s

and also given the final velocity v=10,000 m/s

the time taken to move from A to B = 40 second

The acceleration is defined as the rate of change of velocity with time

we know that the expression for acceleration is given as

a=(v-u)/t

substituting our given data into the expression for a we have

a=(10000-8000)/40

a=2000/40

a=500m/s^2

The planes’ acceleration from A to B is 500m/s^2

Answer:

F = 7.7 [N]

Explanation:

In order to solve this problem, we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

ΣF = m*a

where:

m = mass = 3.5 [kg]

a = acceleration = 2.2 [m/s^2]

F = (3.5*2.2) = 7.7 [N]

Answer:

x = 100.64 [m]

Explanation:

To solve this problem we must use the following kinematics equation.

[tex]v_{f} = v_{i} + (a*t)\\[/tex]

[tex]v_{f} ^{2} = v_{i} ^{2} + (2*a*x)\\[/tex]

where:

Vi = initial velocity [m/s]

Vf = final velocity = 60.16 [m/s]

a = acceleration = 17.98 [m/s^2]

t = time = 7 [s]

Now replacing the values, we have:

(60.16)^2 = 0 + (2*17.98*x)

x = 100.64 [m]

2. The motion of a train

3. A person jogging in the park

The momentum of the system after the Collison have been obtained as  0.20 kg-m/s south.

According to the principle of the conservation of linear momentum, we know that the momentum before collision is equal to the momentum after collision.

In this case, we can see that the two ball are moving in the opposite direction thus the velocity vectors are directed in opposite directions. We would now try to be able to obtain the momentum of the system after the Collison as;

Momentum of the ball moving south - Momentum of the ball moving north

Thus;

0.17 kg(2.8 m/s -  1.6 m/s)

Total momentum of the system =

0.20 kg-m/s south

Answer: For leverage and so the can be easily handled.

Explanation:

Answer:

Explanation:

The kinetic energy (KE) of an object given it's mass and velocity can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} [/tex]

where

m is the mass of the object

v is the velocity

From the question

m = 0.38 kg

v = 120 m/s

We have

[tex]KE = \frac{1}{2} \times 0.38 \times {120}^{2} \\ = \frac{1}{2} \times 0.38 \times 14400 \\ = 0.38 \times 7200[/tex]

We have the final answer as

Answer:

General intelligence refers to the existence of a broad mental capacity that influences performance on cognitive ability measures.

Specific intelligence refers to a person's aptitude in individual 'modalities' or abilities rather than the more general understanding of intelligence.

Explanation:

Answer:

General intelligence can be defined as a construct that is made up of different cognitive abilities.

Specific intelligence can be defined as a collection of subsets or subcategories of abilities rather than a single or general process.
