Answer:
The heat transferred to water equals 1600 kJ
Explanation:
By the conservation of energy we have
All the kinetic energy of the moving vehicle is converted into thermal energy
We know that kinetic energy of a object of mass 'm' moving with a speed of 'v' is given by
Thus
Thus the heat transferred to water equals
Answer:
Explanation:
# taking first number
low = int(input("Enter a number: "))
# if that is valid
if low >= 0:
# considering it as high, sum and input
high = low
sum = low
count = 1
inp = low
# breaking if negative number is entered
while True:
# taking user input of numbers
inp = int(input("Enter a number: "))
if inp >= 0:
# adding it to sum
sum = sum + inp
# checking for low
if low > inp:
low = inp
# checking for high
if high < inp:
high = inp
# tracking count
count = count + 1
else:
break
# printing output
print("\nSum =",sum)
print("count =",count)
print("Average =",round(sum/float(count),2))
print("Lowest =",low)
print("Highest =",high)
# no valid numbers
else:
print("no valid numbers entered")
Answer:
answer for the question :
The ratio of the rate of etch-product formation to the flow rate of etch gas should be greater than 0.15 for uniform etching. Suppose a 200 mm diameter silicon wafer is etched at a rate of 50.0 nm/min in a CF4 plasma.(a) How many Si atoms are removed per minute?(b) What evolution rate of SiF4 does this correspond to in standard cubic centimeters per minute?(c) What minimum flow rate of CF4 should be maintained? "
is explained in the attachment.
