Answer:

a = 5 [m/s²]

Explanation:

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

$v_{f}=v_{o}+a*t$

where:

Vf = final velocity = 20 [m/s]

Vo = initial velocity = 10 [m/s]

t = time = 2 [s]

a = acceleration [m/s²]

Now replacing:

$20 =10 +a*2\\10=2*a\\a=5[m/s^{2} ]$

Answer:

By Newton's third law the cart must then exert an equal and opposite force on the horse. ... If it doesn't accelerate, and it started it rest, it must remain at rest (by the definition of acceleration), and therefore no matter how hard the horse pulls, it can never move the cart

wariber [46]

Explanation:

A chemical reaction is a reaction in which two or more species combine together to form a molecule with a new chemical composition.

In a chemical reaction, the reactants are written on left hand side pointing a forward arrow towards the products which are written on the right hand side.

For example, chemical reaction between hydrogen and oxygen will result in the formation of water. The reaction equation will be as follows.

$2H_{2} + O_{2} \rightarrow 2H_{2}O$

Answer:

Psychology is theoretically diverse.

Explanation:

The theme, 'Psychology is theoretically diverse' means that the psychology has many various views and points. This is because when people make many observations they can go several and many different ways with these observations. This is why Psychology has many perspectives. The differing perspectives provide complete understanding of the human behavior more effectively.

Hence, different perspectives of the three professionals mentioned illustrate this theme.
