When acceleration is less than 0 and velocity is less than 0 then speed is?

When acceleration is less than 0 and velocity is less than 0, the speed is positive. Speed is the absolute value of velocity, so it is always positive regardless of the direction of motion.


What is tyrosine charge at pH 4?

we can't tell the charge of lysine at 4.5 because the PKa is not given. we can only know what charge it carries with the PKa value on carboxyl group or amine group.And to know the charge remember when PH is less than PKa it is always 0 while when PH is higher than PKa it is always -1 on carboxyl group. For the amine group it is always +1 as the PKa is always higher than the PH. so for example we have PKa1 2.19 PKa 5.2 for caboxyl group and 9.67 For amino group. to deter mine the charge is on pka1 the charge -1 because PH4.5 is higher than the pka,while on pka 2 the charge is 0 as PH 4.5 is lower than PKa.while for amine group it is + 1 because PKa is higher than PH4.5 so there the charge on lysine will be calculated -1+0+1=0. that's how i understand it


How do you find the absolute value of something?

If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0


True or false-- The product of two fractions that are each between 0 and 1 is also between 0 and 1?

True, multiplying a value less than 1 by another value less than 1 cannot increase the first value.

No. Probability must be between 0 and 1.


Is x less than or equal to the absolute value of x?

It depents from the value of x.If x>0 then, |x|=xIf x


Is the absolute value of an integer the same as the opposite of that integer?

No. The absolute value of any number is the non-negative value of that number.So, the absolute value of a number X, which is greater than or equal to 0, is X.The absolute value of a number X, which is less than 0, is -X.Note that, in the second case, X < 0 implies that -X > 0.

Is negative 3 bigger than 0?

Any NEGATIVE number is SMALLER then 0, or less in value(-1,-2,-3...) BUT COUNTING numbers are GREATER than 0 (1,2,3...)


What is a value less than zero?

Well a number less than 0 would be -0.9999999 with a bar notation meaning it goes on forever. If you are looking for an integer lower than 0, that would be -1. P.S. An integer is a whole number
