Answer:
15.7m/s
Explanation:
To solve this problem, we use the right motion equation.
Here, we have been given the height through which the ball drops;
Height of drop = 14.5m - 1.9m = 12.6m
The right motion equation is;
V² = U² + 2gh
V is the final velocity
U is the initial velocity = 0
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
V² = 0² + 2 x 9.8 x 12.6
V² = 246.96
V = √246.96 = 15.7m/s
Answer: 80 s
Explanation:
Speed is expressed in v= d/t, derive the equation so we can have time.
First conert km into meters to cancel out both units and only seconds will remain.
1.2 km x 1000m/ 1km = 1200 m
t = 1200 m /15 m/s = 80 s
These are adenine and guanine.
Purines adenine and guanine are double ringed structures that make up DNA. Purines have a characteristic double-ring structure composed of carbon, nitrogen and hydrogen atoms.
Each of purine's rings contain two nitrogen atoms making up a total of four within the double ringed structure. The remaining five positions within the rings are occupied by carbon atoms. The purine ring is encircled by hydrogen atoms which can be replaced by other atoms or groups of atoms to form different purines.
First you have to note down you horoscope for 2-3 days.
Daily observe what is written in your horoscope is true or not. You can observe your entire day movements.
Now you have to conclude whether your horoscope was true or not and you have to write an essay explaining what had happened to you in past observation and conclude whether you believe in astronomy or not depending on your observations
