As a clinical chemist in charge of the testing of blood samples. You are required to mix a solution of sodium chloride with wate

r in the ratio of 2:5. =2:5 2/7 of whole solution chloride 5/7 of whole solution is water 780ml = 2/7 1/7 = 390 ml 5/7 = 1950 Total solution =2730ml 780ml = sodium chloride 1950ml = water 780:1950ml.
How do I put that in standard form and to an appropriate number of significant figures?

A pilot is flying a commercial plane from New York City to Orlando. If the pilot fails to take the Coriolis Effect into account,
grin007 [14]

Answer:

<u>B. East of NYC</u>

Explanation:

We can make this conclusion because for one reason New York City is the Northern Hemisphere, and according to the Coriolis effect <em>when objects in the Northern Hemisphere travel long distances above the ground, </em><em>they will be deflected to the right </em>as a result of earth's rotation.

Hence, going by the map of New York on the Northern Hemisphere, <em>when the (object) flight is deflected to the right, for someone in NYC it will indicate a </em><em>shift to the east of NYC</em><em> </em>since the pilot failed to take the Coriolis Effect into account.

What is the electrical force between q2 and q3? recall that k = 8.99 × 109 n•meters squared over coulombs squared.. 1.0 × 1011 n
max2010maxim [7]

The magnitude of the electrical force between q2 and q3 is given as a ratio between the product of their charges and the square of the distance of separation.

<h3>What is the magnitude of electrical forces between two charges?</h3>

The magnitude of the electrical force between two charges refers to the attractive or repulsive forces that exists between two charges separated by a given distance in an electric field.

The magnitude of the electrical force, F between the two charges q2 and q3 is given be my the formula below

F = \frac{K \times q_2 \times q_3}{d^{2}}

Therefore, the magnitude of the electrical force between q2 and q3 is given as a ratio between the product of their charges and the square of the distance of separation.

An astronaut free falls toward the Earth at a distance of 3 Earth radii from the center of the Earth. What is his acceleration?
s2008m [1.1K]

Answer:

a = 1.1 m/s^2

Explanation:

let a be the acceleration of the astronaut, M be the mass of the earth and r be the radius of the earth.

from the information provide:

the distance r is the radius of the earth.

the distance ,d, the astronaut is from the surface of the earth and the only force acting on the astronaut is gravity, the astronaut accelerates with due to gravity only that is d = 3×r because we consider the earth center as the center of mass and gravity attracts object towards the center of mass.

then, we know that:

a = GM/d^2

  = (6.67×10^-11)(5.972×10^24)/[(3×6371×10^3)^2]

  = 1.1 m/s^2

Therefore, the Astronaut will be accelerating with an acceleration of 1.1 m/s^2 towards the earth.

3. Why is the term cold blooded a misconception? Explain​
jok3333 [9.3K]

Answer:

The term “cold-blooded” implies that these animals are in a never-ending struggle to stay warm. That really isn't correct. A cold-blooded animal can warm up their blood by being in the sun for hours.
