A person eats a container of strawberry yogurt. The Nutritional Facts label states that it contains 255 Calories (1 Calorie = 41

Sever21 [200]

Answer:

mass = 0.44 Kg

Explanation:

given,

Calories contain in the strawberry yogurt = 255 calories

1 Calorie = 4186 J

latent heat of vaporization = 2.42 x 10⁶ J/Kg

mass of perspiration = ?

Energy = 255 calories

Energy = 255 x 4186

= 1067430 J

Energy = mass x latent heat of vaporization

$mass = \dfrac{Q}{L_v}$

$mass = \dfrac{1067430}{2.42 \times 10^6}$

mass = 0.44 Kg

While camping in Denali National Park in Alaska, a wise camper hangs his pack of food from a rope tied between two trees, to kee

Crank

The tension in each of the ropes is 625 N.

Draw a free body diagram for the bag of food as shown in the attached diagram. Since the bag hangs from the midpoint of the rope, the rope makes equal angles θ with the horizontal. The tensions <em>T</em> in both the ropes are also equal.

Resolve the tension T in the ropes into horizontal and vertical components T cosθ and T sinθ respectively, as shown in the figure. At equilibrium,

$2T sin\theta = 50 N$ ......(1)

Calculate the value of sinθ using the right angled triangles from the diagram.

$sin\theta =\frac{0.06 m}{1.5 m} =0.04$

Substitute the value of sinθ in equation (1) and simplify to obtain T.

$2T sin\theta = 50 N\\ T= \frac{50 N}{2 sin\theta}=\frac{50 N}{2*0.06} = 625 N$

Thus the tension in the rope is 625 N.

What is the empirical formula of a compound that contains 27.0% s

eduard

Answer:

Empirical formula of the compound = SOCl₂

Explanation:

QUESTION:What is the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass?

The empirical formula of a compound is its simplest formula. It tells us

* The component element present in a molecule of the compound.

* The ratio in which these elements are combined together, i.e mole ratio.

To calculate the empirical formula of a compound that contains 27.0% S, 13.4% O, and 59.6% Cl by mass. ( Relative atomic mass of S=32gmol⁻¹, 0=16gmol⁻¹, Cl=35.5gmol⁻¹)

Sulphure S, Oxygen O, Chlorine Cl

percentage by mass: 27.0% 13.4% 59.6%

Step 1:

Divide by their relative

atomic mass: 27.0/32.0 13.4/16.0 59.6/35.5

⇒⇒⇒⇒⇒⇒⇒⇒⇒ 0.844 0.838 1.679

Step 2:

Divide by the

smallest mole ratio: 0.844/0.838 0.838/0.838 1.679/0.838

∴ 1 : 1 : 2.

from the analysis above, the compound contains Sulphur, Oxygen and Chlorine in the ratio of 1:1:2.

∴ Empirical formula of the compound = SOCl₂

Iron atoms have been detected in the sun's atmosphere, some with many of their electrons stripped away. What is the net electric

BaLLatris [955]

Answer:

2.88 × 10⁻¹⁸ C

Explanation:

The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C

The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 × 1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
