Answer:
before this type of attack, high acceleration is the most important thing.
Explanation:
As the zebra is ambushed by the crocodile the most important thing is a quick reaction, in this attack the most likely is that the crocodile is in the water so it cannot run after the zebra.
Consequently, before this type of attack, high acceleration is the most important thing.
In vacuum, going at 2.99×10^8 m/s.
Answer:

Explanation:
Considering an object that moving about in a circular path, the equation for such centripetal force can be computed as:

The model for the person can be seen in the diagram attached below.
So, along the horizontal axis, the net force that is exerted on the person is:

Dividing both sides by "m"; we have :

Making "v" the subject of the formula: we have:


So, when
= 0; the velocity is maximum
∴




Hence; the maximum walking speed for the person is 
The smaller the atom,the larger the first I.E.
Answer:

Explanation:
Ohm's law states the relationship between voltage, resistance and current in an electrical circuit containing passive elements only:

where
V is the voltage supplied by the battery
R is the resistance of the circuit
I is the current
From the equation, we see that the voltage, V, is directly proportional to the current in the circuit, I.
