B. Piaget’s theory of cognitive development begins in the sensorimotor stage, where children are still making sense of the world through their senses, and ends in the formal operational stage, in which a person begins to think abstractly and reason about hypotheticals.
Answer:
This solution is implemented in python
num1 = float(input("Number 1: "))
num2 = float(input("Number 2: "))
num3 = float(input("Number 2: "))
print("Sum: "+str(num1+num2+num3))
Explanation:
This line prompts the user for the first number
num1 = float(input("Number 1: "))
This line prompts the user for the second number
num2 = float(input("Number 2: "))
This line prompts the user for the third number
num3 = float(input("Number 2: "))
This calculates and prints the sum
print("Sum: "+str(num1+num2+num3))
A redshift can be described as a galaxy that is moving away form us. So the correct one is D.
