Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.
Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.
Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.
Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.
Explanation:
Answer:
total = 0
count = 0
while(True):
grade = float(input("Enter a grade: "))
if grade < 0:
break
else:
total += grade
count += 1
average = total/count
print("The average is: " + str(average))
Explanation:
*The code is in Python.
Initialize the total and count as 0
Create a while loop that iterates until a specific condition is met inside the loop
Inside the loop, ask the user to enter a grade. If the grade is smaller than 0, stop the loop. Otherwise, add the grade to the total and increment the count by 1.
When the loop is done, calculate the average, divide the total by count, and print it
The speed of light is 299212.5984 (kilometers per second), if the light 1.27 seconds to travel from Earth to the moon. If the distance is 380,000 km to the moon.
Explanation:
The given is,
Light 1.27 seconds to travel from Earth to the moon
Distance is
380,000 km to the moon
Step:1
Formula to calculate the speed,
................................(1)
Where, d - Distance
t - Time taken
From given,
d = 380000 km
t = 1.27 seconds
Equation (1) becomes,
= 299212.5984
Speed of light, s = 299212.5984 kilometers per second
Result:
The speed of light is 299212.5984 (kilometers per second), if the light 1.27 seconds to travel from Earth to the moon. If the distance is 380,000 km to the moon.
