Answer:D

Explanation:

The force of gravity from Mars will pull on the space probe the same amount no matter how far away it is​, so option D is correct.

All material objects in the universe are subject to the force of gravity, also known as gravitation. The force of gravity tends to draw any two non-zero mass objects or particles toward one another. Subatomic particles and galaxy clusters are both affected by gravity, as are objects of all sizes.

Due to the law of gravity, or gravitation, which draws all objects with mass in its vicinity toward it, Mars' gravitation is a natural occurrence. Due to the planet's lesser mass, its gravity is weaker than that of Earth. On Mars, the gravitational acceleration fluctuates, but on average it is 3.72076 m/ s² (or around 38% of Earth's).

Therefore, the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is​.

Answer:

A) but be sure and read the answer.

Explanation:

If the object does not move at all, (that's an important restriction) the net force = 0. That being so, the acceleration must be 0 as well. But there is no law saying that there cannot be a constant motion and that's why the restriction is important.

Answer:

(a) k = 80 N/m   (b) x = 75 cm

Explanation:

The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"

Given that,

Force exerted on the spring, F = 24 N

Elongation in the spring, k = 30 cm =0.3 m

(a) We know that, the force on the spring is given by :

F = kx

Where

k is spring constant

So,

[tex]k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m[/tex]

(b) When F = 60 N,

[tex]x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm[/tex]

Hence, this is the required solution.

Answer:

add the Resistance

2(100)= 200

2) 200 ohms

If two 100 ohms resistors are placed in series, their total resistance will be 200 ohms

When two or more resistors are connected end to end consecutively , they are said to be connected in series combination .Total resistance in  series combination is calculated as the algebraic sum of individual resistances

General formula = R (equivalent ) = R1 + R2 + R3 + .......

let R1 = 100 ohms

R2 = 100 ohms

R(equivalent resistance in series combination )= R1 + R2

R = 100 + 100

R = 200 ohms

If two 100 ohms resistors are placed in series, their total resistance will be b) 200 ohms

Answer:

Awareness was selected because it was beneficial to organisms in particular environments.

Explanation:

Based on the article, natural selection is a phenomenon that recognizes and allows traits that are useful to an organism and that would be favorable for it to be passed from one generation to another.

Natural selection marked awareness as a useful trait that would be beneficial for organisms because it helped them adapt well to the particular environments that they found themselves. For example, this ability helped an organism to be able to recognize where it could get food and light in its environment.

Answer:

the nucleus of the atom you have conserved almost all its mass in a very small volume

Explanation:

In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.

The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,

          V_atom / V_nucleo = 10⁴

Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.

In summary, the phrase that describes the process is:

Answer:

The scale read 1280 N.

Explanation:

Given that,

The mass of a person, m = 80 kg

We need to find the scale reading when the elevator is moving upward at 6.2 m/s².

We know that, when an elevator moves up, the reading on the scale is given by :

N-mg=ma

N=m(a+g)

Put all the values,

N = 80(6.2+9.8)

= 80(16)
