A boy whirls a stone in a horizontal circle of radius 1.8 m and at height 1.8 m above level ground. The string breaks, and the s

Answer:

Acceleration is 148.33\ m/s^{2}

Solution:

As per the question:

Radius of the circle, R = 1.8 m

Height above the ground, h = 1.8 m

Horizontal distance, x = 9.9 m

Now,

The magnitude of the centripetal acceleration can be calculated as:

a_{c} = \frac{v^{2}}{R}        

where

v = velocity

R = radius

a_{c} = centripetal acceleration

Now, if we consider the vertical component of motion only, then considering the initial velocity, 'u' = 0, from kinematic eqn:

h = ut + \frac{1}{2}gt^{2}                

h = 0.t + \frac{1}{2}gt^{2}                

t = \sqrt{\frac{2h}{g}}                

t = \sqrt{\frac{2\times 1.8}{9.8}}

t = 0.606 s

Now, for the horizontal component of velocity:

x = vt

v =\frac{x}{t}

v =\frac{9.9}{0.606} = 16.34\ s

Now, we know that the centripetal acceleration is given by:

a_{c} = \frac{16.34^{2}}{1.8} = 148.33\ m/s^{2}

A double stranded dna molecule contains 300 adenine molecules and 240 cytosine molecules. How many guanine molecules are in this
Maurinko [17]

Answer:

240 molecules

Explanation:

According to the chargaff rules, the amount of adenine  is equal to the amount of thymine  and the amount of guanine  is equal to the amount of cytosine. Therefore:

G=C\\A=T

Now, its easy to conclude:

G=C=240\hspace{3}molecules
