If they did not communicate then there wouldn't be a logical explanation for the experiment ..
type answers below ..
Answer:
electrical energy is a from of energy cause by electrons. The electrons flow the metals giving a shock of energy.
Explanation:
it can be used to power things with wires inside
have a nice day and mark me brainliest! :)
The importance of fat in the diets of our ancestors was mainly a result of its energy-storing properties.
Option B
Explanation:
Earlier ancestors or say, hominids ancestor were at the inception of the evolutionary world developed a trend on eating whatever they could find. The ancestors are believed to be scavengers rather than hunters as the evolutionary and nutrition biology suggests.
They had to travel and work for the food and as they were scavengers, it was not guaranteed to have food on a daily basis, so the fat has energy storing properties and for which its importance was realized in the diet. Later when they became hunters, protein became more important in their diet.
Answer:
84m
Explanation:
Using the kinematics equation we can come up with the answer:

Where:
Vf = final velocity
Vi = initial velocity
t = time
In your problem we have the following given:
Vf= 0 m/s
Vi = 21 m/s
t = 8 seconds
The Vf is zero because the car stopped. The distance given in this case is not useful in determining the car's distance so we will solve it. So just fill in the equation with the given:

Thankfully, the deer was not hit!
