<u>Answer:</u>

<em>1. A NaCl solution with a concentration of 50g/100mL of water at 40°C:</em> The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.

<em>2. A sugar solution with a concentration of 200g/100mL of water at 40°C: </em>The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.

<em>3. A sugar solution with a concentration of 240g/100mL of water at 40°C:</em> The sugar solution with a given concentration is saturated at given temperature.

A race car starts from rest on a circular track of radius 378 m. The car's speed increases at the constant rate of 0.580 m/s2. A
insens350 [35]

Answer:

a) V=14.904m/s

b) d = 191.49 m

c) t= 25.696 s

Explanation:

From the question we are told that:

Radius r =378m

Acceleration a=0.580

a)

Generally the  equation for speed of the car is mathematically given by

 a=\frac{v^2}{r}

 V=\sqrt{a*r}

 V=\sqrt{0.58*383}

 V=14.904m/s

b)

Generally the  equation for distance traveled of the car is mathematically given by

 V^2=u^2+2ad

 d=\frac{V^2}{2a}

 d=\frac{14.904^2}{2*0.58}  

 d = 191.49 m

c)

Generally the  equation for time of the car is mathematically given by

 V=u+at

 t=\frac{V}{a}

 t=\frac{14.904}{0.58}

 t= 25.696 s

kinetic energy = 18 joules

Explanation:

here's the solution :-

=》

k.e. =  \frac{1}{2}  \times m {v}^{2}

=》

k.e. =  \frac{1}{2}  \times 4 \times 3 \times 3

=》

k.e. = 2 \times 9

=》

1) A U-tube, in which both ends are open to the atmosphere, is partially filled with water. Oil which does not mix with water is
ser-zykov [4K]

Answer:

1) 916 kg/m³

2) 9.8566×10⁴ Pa

Explanation:

1) Originally, the water is at the same level on both sides.  When the oil is added, one side goes down 67.5 mm and the other side goes up 67.5 mm.  The top of the oil is 12.3 mm above the water, so the total height of the oil relative to the low end of the water is:

12.3 mm + 67.5 mm + 67.5 mm = 147.3 mm

And the height of the water relative to the low end is:

67.5 mm + 67.5 mm = 135 mm

The pressure at the bottom of the oil equals the pressure of the water at the same elevation.

P = P

ρgh = ρgh

ρh = ρh

ρ (147.3 mm) = (1000 kg/m³) (135 mm)

ρ = 916 kg/m³

2) P = ρgh

P = (1.3608×10⁴ kg/m³) (9.7835 m/s²) (0.74035 m)

P = 9.8566×10⁴ Pa
