The correct answer is Van de Graaff generator. A large electrostatic generator is commonly called a Van de Graaff generator. This large generator is a device for the production of high voltage by means of endless belt collecting of electrostatic charge.
Answer:
<h3>10.0m</h3>
Explanation:
The displacement of the dog is the distance moved in a specified direction. It will be gotten using pythagoras theorem as shown;
d² = 8²+6²
d² =64+36
d² = 100
square root both sides
√d² = √100
d = 10m
Hence the displacement of the dog to the nearest tenth is 10.0m
B. The hormone erythropoeitin increases the production of red blood cells when oxygen levels are low.
Answer:
the average velocity of the ball is 5 m/s.
Explanation:
Given;
initial position of the ball, x₁ = 12 m East
final position of the ball, x₂ = 8 m West
initial time of motion, t₁ = 10.0 s
final time of motion, t₂ = 6.0 s
The average velocity is calculated as follows;
let the Eastward direction be positive
Let the westward direction be negative
Therefore, the average velocity of the ball is 5 m/s.
