Fredd must use the trait theory for the online personality tests because it is based on distinctive features.

What is the trait theory?

The trait theory is a model that states people have certain basic personality traits which are distinctive features.

The trait theory is always based on the strength of these basic human trait characteristics.

The trait theory is based on three types of features capable of being used to describe personality, which include stability, consistency and individual differences.

7. An object with a mass of 2.0 kg is accelerated from rest. The above graph shows the magnitude of the net force
as a function of time. At t = 4.0 s the object's velocity is closest to which of the following?
a. 2.0 m/s
b. 4.0 m/s
C. 10 m/s
d. 13 m/s

Answers

The object's velocity accelerating from rest from the applied force and time is closest to 4 m/s.

Velocity of the object

The velocity of the object can be determied by applying Newton's second law of motion as shown below;

F = ma

where;

F is the applied forcem is the mass of the objecta is the acceleration of the object

The acceleration of the object is calculated as follows;

a = F/m

at time, t 4.0 s, the corresponding force = 2 N

a = 2/2

a = 1 m/s²

Velocity of the object is calculated as;

v = u + at

v = 0 + 1 x 4

v = 4 m/s

Thus, the object's velocity accelerating from rest from the applied force and time is closest to 4 m/s.

You are riding your bike downtown at a speed of 15 m/s and you see

to a complete stop. What is your acceleration during this time?

Answers

The acceleration of the rider initially going at a speed of 15m/s but comes to a stop at 50m is 2.25m/s².

How to calculate acceleration?

The acceleration of a moving body can be calculated by using the following formula:

v² = u² + 2as

Where;

v = final speed u = initial speeda = accelerations = distance

15² = 0² + 2×a×50

225 = 0 + 100a

a = 225/100

a = 2.25m/s²

A current of 5. 0 amperes is passing through a piece of wire. Determine how long it takes for 30 coulombs of charge to pass through this wire

Answers

The time taken for the charge to pass through the cross-section of the wire is 6.0s.

Given the data in the question;

Current; [tex]I = 5.0A[/tex]

Charge; [tex]Q = 30C[/tex]

Time; [tex]t = \ ?[/tex]

Current

Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.

If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;

[tex]I = \frac{Q}{t}[/tex]

Where Q is the charge and t is time elapsed.

We substitute our given values into the expression above to determine the time it took the charge to pass through this wire.

[tex]I = \frac{Q}{t}\\ \\5.0A = \frac{30C}{t} \\\\t = \frac{30C}{5.0A} \\\\t = 6.0s[/tex]

If the barge is made out of 4.8- cm -thick steel plate on each of its four sides and its bottom, what mass of coal can the barge carry in freshwater without sinking

Answers

The maximum mass of coal that the barge will carry in freshwater without sinking is 0.111 kg.

Volume of the barge

The volume of the barge is calculated as follows;

V = L³

V = (4.8 cm)³

V = 110.6 cm³

Density of the barge

For the barge to float in freshwater, its density must be less or equal to density of water.

density(barge) = density(water)

density(barge) = 1 g/cm³

Maximum mass to be carried by the barge without sinking

mass = density x volume

mass = 1 g/cm³ x 110.6 cm³

mass = 110.6 g
