Explanation:
Relation between length of a curve and angle is as follows.
l = 
where, R = radius of curve
= angle in radians
Also, l = 
.......... (1)
If curve has a degree of curvature 
for standard length s, then
R = 
........... (2)
Now, substitute the value of R from equation (2) into equation (1) as follows.
l = 
If s = 30 m, then calculate the value of l as follows.
l =
= 
= 452 m
thus, we can conclude that the length of the curve is 452 m.
Answer:
being responsible is owing up to the possible
consequences of your decision whether it was right or wrong.
communication is a two way process in which there is a messenger and receiver
one of the ways by which a person could be responsible is by saying 'I'
in all the things he would say, instead of 'we'
for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.
here u r establishing ownership on the things you want to say to the person
Answer:
7700000000
Explanation:
so 7.7 x 10 to the power of 9 is in standard form
to put it into a number you just need to times it by 1000000000
however your answer will only have 8 zeros because of the decimal point
The concentration of hydrogen ions in a solution is a measure of its acidity. So the correct option is (b) false.
When an Arrhenius acid is dissolved in water, hydrogen ions are produced:
H+(aq) + A- = HA + H2O (aq)
Here, H+ is the hydrogen cation, A- is the solvated anion, also known as the conjugate base, and HA is the non-dissociated acid. When an Arrhenius base is dissolved in water, hydroxide ions are produced:
BOH + H2O → B+(aq) + OH-(aq)
Is a material with at least one hydrogen atom that has the ability to split apart in an aqueous solution to produce an anion and an H + ion (a proton), creating an acidic solution. Bases are substances that, when dissolved in water, create hydroxide ions (OH) and a cation, resulting in a basic solution.
