Gravity is the force that objects exert on each other because of their masses. The strength of the gravitational force between two objects
depends on two factors, mass and distance. How is gravity related to mass and distance? Choose ALL the statements that apply.
If one of the masses is doubled, the force of gravity between the objects is doubled.
As distance between the objects increases, the force of gravity decreases.
As distance between the objects increases, the force of gravity increases.
The more mass two objects have, the less the force of gravity the masses exert on each other
Greater mass results in greater force.

Answer:

temporary iron r made up of soft iron its " true.."

a. more gravity

This is the answer.

Answer:

the average velocity of the ball is 5 m/s.

Explanation:

Given;

initial position of the ball, x₁ = 12 m East

final position of the ball, x₂ = 8 m West

initial time of motion, t₁ = 10.0 s

final time of motion, t₂ = 6.0 s

The average velocity is calculated as follows;

[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_1 \ - \ x_2}{t_1 \ - \ t_2}[/tex]

let the Eastward direction be positive

Let the westward direction be negative

[tex]\frac{x_1 \ - \ x_2}{t_1 \ - \ t_2} = \frac{12 \ - \ (-8)}{10 -6}= \frac{20}{4} = 5 \ m/s[/tex]

Therefore, the average velocity of the ball is 5 m/s.

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Answer:

C. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter

Explanation:

A wave is any disturbance that transfers energy from one location to the other via a substance called medium. It is important to note that a wave only conveys energy and not matter. For example, sound wave is a type of wave that carries sound energy from one place to another via mediums such as water, air etc.

Hence, according to this question, a wave can be described as a disturbance that travels through a medium with a transfer of energy and WITHOUT A TRANSFER OF MATTER.

Answer:

this frequency is in the near UV range

Explanation:

The accelerated movement of a charge creates an electromagnetic wave, the speed of the wave is the speed of light

         c = λ f

the emitted frequency is f = 10⁶ 10⁹ Hz = 10¹⁵5 hz,

light of this frequency is in the near UV range

Answer:

Acceleration = 5.3645 m/s²

Explanation:

Given the following data;

Initial velocity, u = 0mph

Final velocity, v = 60 mph

Time, t = 5 seconds

To find the acceleration (also used in the second law of motion), we would use the following formula;

A = (v - u)/t

Conversion:

Miles per hour to meters per seconds;

0 mph = 0 mps

1 mph = 0.44704 mps

60 mph = 60 * 0.44704 = 26.8224 mps

Next, we find the acceleration;

Acceleration = (26.8224 - 0)/5

Acceleration = 26.8224/5

Acceleration = 5.3645 m/s²

Answer:

The friction of braking heats up the tire and the road. The temperature is so high that it reaches the melting point of the rubber in the tire. The melting rubber is what leaves a mark on the road.

Explanation:

Answer:

the friction of braking heats up the tires and the road. then the temperature gets even hotter to the point where it melts the rubber.

Answer:

F' = 2F

Explanation:

The gravitational force of attraction between asteroids is given by Newton's Law of Gravitation:

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]

where,

F = Force

G = Universal Gravitational Constant

m₁ = m₂ = m = mass of each asteroid

r = distance between asteroids

Therefore,

[tex]F = \frac{Gm^2}{r^2}[/tex]   --------------------- eq(1)

Now, if we double the mass of one asteroid:

[tex]F' = \frac{G(2m^2)}{r^2} \\\\F' = 2\frac{Gm^2}{r^2}[/tex]

using equation (1):

F' = 2F

Answer:

A

Explanation:

this because

gravitational potential energy = mass x height x gravitational field strength

so let's assume mass is 2 kg and gravitational field strength is 10 N /kg

so when height is very low, take it as 3 m

gravitational potential energy= 2 x 3 x 10 = 60 j

but when height is 6m

gravitational potential energy = 2 x 6 x 10 = 120 j

so when the height is the greatest, the gravitational potential energy is the highest

so A is the heighest so it has the highest gravitational potential energy.

hope this helps
