How were Jupiter, Saturn, Uranus, and Neptune formed?
Explanation:
They were formed by accretion
Answer:
(For me they were formed by God.)
Planets are believed to have formed through the accumulation of a large number of small bodies. The orbits of these cores then evolve into orbits that resemble those of Uranus and Neptune, as a result of gravitational interactions with the small bodies in the outer disk of the protosolar nebula.

4. Two students have volunteered to explore the galaxy in a spaceship. As they travel through space, they
measure the magnitude of the gravitational force between their spaceship and the Earth. They find that the
gravitational force on the spaceship is -
A. proportional to the distance from the Earth
B. inversely proportional to the distance from the Earth
C. proportional to the square of the distance from the Earth
D. inversely proportional to the square of the distance from the Earth
Answer:B
Explanation:
They find that the gravitational force on the spaceship is inversely proportional to the distance from the Earth. The correct option is B.
What is gravitational force?The gravitational pull would be stronger if the gap were cut in half. Coulomb's law, states that the gravitational force between two items in the universe is directly proportional to the product of the masses of the objects.
And inversely proportional to the distance between them is used to calculate the gravitational force between two objects in the universe. Whether there is a body there or not, gravity is the force between two bodies.
Everybody in the cosmos is drawn to every other body by a force that is directly inversely correlated to the square of the distance between them and directly inversely correlated to the product of their masses.
Therefore, the correct option is B. inversely proportional to the distance from the Earth.

The property of our eyes that makes us perceives a rotating coloured disc as white.
A car travels for 10s at a steady speed of 20m/s along a straight road. The traffic lights ahead change to red, and the car slows down with a constant deceleration, so that it stops after an additional 8 seconds.
Use your graph to deduce how far the car has travelled during the 18 seconds described.
Answer:
280 meters
Explanation:
You should get the speed
And you should use the graph….
To get the distance using the graph the rule is …(area under graph) which is equal to area of triangle + area of the rectangle
Area of triangle = 0.5 x length x width
Area of rectangle = Length x width
(0.5 x 8 x 20 ) + ( 10 x 20 ) = 280 meters

The fulcrum is the
point of support on which a lever rotates.
force opposing the applied force.
distance an object moves when doing work.
stored energy of an object.
Answer:
point of support on which a lever rotates.
Explanation:
The fulcrum is the point of support on which a lever rotates. Fulcrum is a pivotal part of simple machines.
The fulcrum provides the platform for a lever to torque.
The force that opposes motion by the applied force is termed the frictional force. Friction is a force that opposes motion. The stored energy of an object is its potential energy. The potential energy is the energy due to the position of a body. The distance an object moves when doing work is termed its displacement.3 A jet fighter has a mass at take-off of 28 000 kg.
a)Its engines produce a force of 70 000 N. What
is its acceleration?
b) What is its acceleration if the force from the
engine is increased to 120 000 N?
Answer:
A. 2.5 m/s²
B. 4.29 m/s²
Explanation:
A. Determination of the acceleration.
Mass (m) = 28000 Kg
Force (F) = 70000 N
Acceleration (a) =?
Force (F) is simply defined as the product of mass (m) and acceleration (a). Mathematically, it is expressed as:
Force (F) = mass (m) × acceleration (a)
F = ma
Divide both side by m
a = F / m
With the above formula, we can obtain the acceleration as follow:
Mass (m) = 28000 Kg
Force (F) = 70000 N
Acceleration (a) =?
a = F / m
a = 70000 /28000
a = 2.5 m/s²
B. Determination of the acceleration.
Mass (m) = 28000 Kg
Force (F) = 120000 N
Acceleration (a) =?
a = F / m
a = 120000 /28000
a = 4.29 m/s²

How far does an object travel if it starts from rest and accelerates at a rate of 2.0 meters per second2 for 6.5 seconds?
Answer:
42.25 m
Explanation:
According to the question;
u = 0 m/s (journey started from rest)
a = 2 m/s^2
t = 6.5 secs
Given that;
s = ut + 1/2at^2
s = (0 * 6.5) + 1/2 * 2 * (6.5)^2
s = 0 + 42.25
s = 42.25 m

passing between two points?
Electric potential difference is named to the work done per coulomb of charge passing between two points.
What is electric potential?An object's electrical potential energy is determined by two factors: the charge the thing carries internally, and the position of the object in relation to other electrically charged objects. The amount of effort required to move an object from one location to another against an electric field determines the strength of the electric potential.
The total potential energy that a unit charge would have if it were positioned everywhere in space is known as electric potential energy.
The energy gained when an object moves against an electric field is known as the electric potential energy. The electric potential is calculated for any charge by dividing the potential energy by the charge.

A. Gravity pulled most of the matter into the center of the solar
system.
B. Gravity caused the planets and Sun to have spherical shapes.
O C. Gravity held the pieces of forming planets together.
D. Gravity evenly distributed matter throughout the solar system.
Answer:
it's answer is B
A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the centre to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three -dimensional circle

D. The General Adaptation Syndrome
Explanation:
Hans Selye, an endocrinologist, developed the "Stress Theory." He showed the relationship of "stress" to the person's development of disease.
Under stress, a person's body experiences changes. The person tries to cope with these through three stages: Alarm Reaction Stage, Resistance Stage and Exhaustion Stage. It is at the last stage that a person's immune system is placed at a huge risk. Once the person is exposed to a stressor for a period of time, he becomes hopeless and his body tends to give up coping. He then succumbs to stress-related illness.
