Answer:108.71 mL
Explanation:
Given
Volume of sample V=150 mL
concentration of sucrose solution 35 % w/w i.e. In 100 gm of sample 35 gm is sucrose
specific gravity =1.115
Density of solution
Thus
![\rho _s=1.15\times 1 gm/mL=1.115\ gm/mL](https://tex.z-dn.net/?f=%5Crho%20_s%3D1.15%5Ctimes%201%20gm%2FmL%3D1.115%5C%20gm%2FmL)
mass of sample ![M=1.115\times 150=167.25\ gm](https://tex.z-dn.net/?f=M%3D1.115%5Ctimes%20150%3D167.25%5C%20gm)
mass of sucrose ![m_s=0.35\times 167.25=58.53\ gm](https://tex.z-dn.net/?f=m_s%3D0.35%5Ctimes%20167.25%3D58.53%5C%20gm)
mass of Water ![m_w=108.71 gm](https://tex.z-dn.net/?f=m_w%3D108.71%20gm)
Volume of water ![=108.71\times 1=108.781 mL](https://tex.z-dn.net/?f=%3D108.71%5Ctimes%201%3D108.781%20mL)
Answer:
Explanation:
Force between charge is given by the following expression
F = k Q₁ Q₂ / R² , k = 9 x 10⁹ , Q₁ and Q₂ are charges , R is distance between charges .
Putting the given values ,
.85 = 9 x 10⁹ x 7.1 x 10⁻⁶ x Q₂ / 5.4²
Q₂ = .85 x 5.4² / (9 x 10⁹ x 7.1 x 10⁻⁶ )
= .38788 x 10⁻³ C .
= 387.88 x 10⁻⁶ C .
C. Series
Consider resistors in a circuit - if all the resistors in the circuit are in series and one of the resistors fails then no current can flow thru the circuit,
If the resistors are in parallel then then each resistor experiences the same voltage drop regardless of whether or not any resistor in particular is carrying current.
Answer:
60
Explanation:
Every 60 minutes is an hour
Answer: Accoding to research "Triton is unique among all the large moons in the solar system because it orbits Neptune in a direction opposite to the planet's rotation (a "retrograde" orbit). It is unlikely to have formed in this configuration and was probably captured from elsewhere."
