Answer:

a) 65.74 = 4 significant figures

b) 60.009 = 5 significant figures

c) 66_ = 2 significant figures

d) 65.750 = 5 significant figures

Explanation:

Significant figures or digits is defined as the total number of digits in a number that have meaning and contribute to the precision of the given number.

a) 65.74 = 4 significant figures, all the non-zero figures are considered significant.

b) 60.009 = 5 significant figures, zeros present between non-zero figures are significant.

c) 66_ = 2 significant figures, all the non-zero figures are considered significant.

d) 65.750 = 5 significant figures, all the non-zero figures and the trailing zero after the decimal are significant.

Find the horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40m/s

vfiekz [6]

To Find :

The horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40 m/s.

Solution :

The horizontal range of a projectile is given by :

$R = \dfrac{u^2 sin 2\theta}{g}$ ( Here, g is acceleration due to gravity = 10 m/s² )

Putting all value in above equation :

$R = \dfrac{40^2 \times sin (2 \times 15)}{10} \ m\\\\R = \dfrac{1600 \times 1}{2\times 10} \ m\\\\R = 80 \ m$

Therefore, the horizontal range of projectile is 80 m.

g Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at

Alborosie

Answer : The ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2

Explanation :

The relation between the equilibrium constant and standard Gibbs free energy is:

$\Delta G^o=-RT\times \ln Q\\\\\Delta G^o=-RT\times \ln (\frac{[A]_{inside}}{[A]_{outside}})$

where,

$\Delta G^o$ = standard Gibbs free energy = -14.1 kJ/mol

R = gas constant = 8.314 J/K.mol

T = temperature = $25^oC=273+25=298K$

Q = reaction quotient

$[A]_{inside}$ = concentration inside the cell

$[A]_{outside}$ = concentration outside the cell

Now put all the given values in the above formula, we get:

$-14.1\times 10^3J/mol =-(8.314J/K.mol)\times (298K)\times \ln (\frac{[A]_{inside}}{[A]_{outside}})$

$\frac{[A]_{inside}}{[A]_{outside}}=296.2$

Thus, the ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2
