Not sure what you are asking but if it's a true or false question then the answer is true

Answer:  True

Explanation:  JJ Thomson discovered electrons but he could not explain the position of the electrons. Rutherford explained that the electrons revolve around the nucleus but he also could not explained the further consequences.

After this, Bohr explained that the electrons do revolve around the nucleus but in a certain defined location known as Orbitals.

Thus the probability of finding the electron is maximum in these orbitals.

A powder sample weighing 250 g and having a surface area of 1 m2/g is dispersed in 1 L of water. After 10 minutes, 0.4 g of the
lisabon 2012 [21]

Answer:

a)

K = 2.64 * 10^{-8}

b)

15 \frac{5}{8} hours

Explanation:

Given

Surface Area (S) of 250 grams of powder sample = 250 square meter.

S = 2500000 square centimeter

V\frac{dC}{dT} = 0.40 grams/minute

V\frac{dC}{dT} = \frac{dM}{dT} = \frac{0.40*60}{10} = 0.66 mg per second

C_s = 0.01 gram per cubic meter = 10 mg/ml

a)

\frac{dM}{dT} = K SC_s

0.66 =  K* 2500000* 10\\

K = 2.64 * 10^{-8} cm /sec

b) Time taken

Time taken to sink

\frac{10*60}{0.4} * 37.5  = 56,250

Time in hours

15 \frac{5}{8} hours

The planet mars has two moons, deimos and phobos. phobos is about 9,000 km from mars and is about six times more massive than de
Misha Larkins [42]
F = G(m1 m2)/(r)^2

Let m1 be the mass of Mars
Let m2 be the mass of Deimos.
Therefore, 6m2 is the mass of Phobos.

We know that G, m1, and m2 are just constants.

Phobos:

Fp = G(m1 * 6m2)/(9000000m)^2 = 7 × 10^(-14) * G m1 m2

Deimos

Fd = G(m1 * m2)/(23000000m)^2 = 2 × 10^(-15) * G m1 m2

Mars exerts a stronger gravitational force on Phobos since Fp > Fd

Which phrase best describes an individual organ?
HACTEHA [7]

Answer:

made of different kinds of tissues

Explanation:

cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism

1. the simplest unit of life - cell

2. a individual organ - would be made of different kinds of tissues

3. tissues - would be made of one kind of cell

4- an organ system - meets all the needs of a organism

also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

good luck :) I hope this was right
