Is there a difference in speed between a car going forwards at 5m/s and a car moving backwards at 5m/s
slava [35]

There is NOT a difference in speed between a car going forwards at 5 m/s and a car moving backwards at 5 m/s.

Speed is just the rate of change of the position of an object. It is calculated by dividing the change in position (distance traveled) by the time it takes to move said distance.

The distance between the two points is always positive because the direction does not matter.

However, if we are looking for the velocity, the direction DOES matter. In this example, the velocity moving forwards is 5 m/s while the velocity moving backwards is -5 m/s.

In other words:

<em>Speed </em>is looking at the <em>magnitude</em>

<em>Velocity </em>is looking at the <em>magnitude </em><em>and </em><em>direction.</em>

Why might the knoblike proteins on the outer surface of hiv hold a key to the production of a vaccine against aids?
Nataly_w [17]

This is because the GP120 protein of the HIV virus that forms the ‘knob’ is essential for the infection of CD4 cells of the immune system by the virus. The glycoprotein is, therefore, a good target for vaccines especially since the molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.

The concept of population neural coding proposes that a specific object, like a face, is represented across a number of what?
Varvara68 [4.7K]

Answer:

The concept of population neural coding proposes that a specific object, like a face, is represented across a number of neurons.

Explanation:

Neuron coding is processing the information by neurons, in a way that neurons generate electric impulses for coding. In population coding, the neurons give responses that could combine and that is how the entering information is determined.
