Write a function named is_float(s) that takes one argument that is a string. It returns True if string s represents a floating p

oint value and returns False otherwise. You are required to use try-except. The basic concept is to "try" to convert string s to a float and if it succeeds, return True, but if it fails (that is, an exception is raised), return False. Note that float() raises a ValueError exception.

Answer:

Explanation:

# Python Programme

#!/usr/bin/python

# Function definition is here

def is_float( str ):

try:

float(str)

return True

except ValueError:

return False

# Now you can call is_float function

print(is_float("3.45"))

print(is_float("3e4"))

print(is_float("abc"))

print(is_float("4"))

print(is_float(".5"))

In multi-grade oil what is W means?
irga5000 [103]

Answer:

winter viscosity grades

Explanation:

The “W”/winter viscosity grades describe the oil's viscosity under cold temperature engine starting conditions. There's a Low Temperature Cranking Viscosity which sets a viscosity requirement at various low temperatures to ensure that the oil isn't too thick so that the starter motor can't crank the engine over.

The air contained in a room loses heat to the surroundings at a rate of 60 kJ/min while work is supplied to the room by computer
charle [14.2K]

Answer:

The net amount of energy change of the air in the room during a 10-min period is 120 KJ.

Explanation:

Given that

Heat loss from room (Q)= 60 KJ/min

Work supplied to the room(W) = 1.2 KW = 1.2 KJ/s

We know that  1 W = 1 J/s

Sign convention for heat and work:

1. If heat is added to the system then it is taken as positive and if heat is rejected from the system then it is taken as negative.

2. If work is done by the system then it is taken as positive and if work is done on the system then it is taken as negative.

So

Q = -60 KJ/min

In 10 min Q = -600 KJ

W = -1.2 KJ/s

We know that

1 min = 60 s

10 min = 600 s

So   W = -1.2 x 600 KJ

W = -720 KJ

WE know that ,first law of thermodynamics

Q = W + ΔU

-600  =  - 720 + ΔU

ΔU = 120 KJ

The net amount of energy change of the air in the room during a 10-min period is 120 KJ.
