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.A train travels 200km/hr. how much distance will the train be from the station in 2.5 hours?
Answer:
500km
Explanation:
Given parameters:
Speed = 200km/hr
Time taken = 2.5hrs
Unknown:
Distance = ?
Solution:
To solve this problem, we use the speed, time and distance equation.
Therefore;
Distance = Speed x time
So;
Distance = 200 x 2.5 = 500km

per conlomb of charge
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.

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.

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.

A student conducts an experiment in which an object travels across a horizontal surface while for 2 s a net force is applied to a 2 kg object that initially travels with a speed of 0.5 m/s. Data collected from the experiment are used to create the graph of the magnitude of the applied force exerted on the object as a function of time is shown. All frictional forces are considered to be negligible. Can the student use the graph and the known data to determine the momentum of the object after the force has been applied?
Yes, because the average force exerted on the object can be used with the time interval of 2 s to determine the change in momentum of the object by using Δp⃗ =F⃗ Δt.
Yes, because the area bound by the best-fit line and the horizontal axis from 0 s to 2 s can be used to determine the change in momentum of the object.
No, because the data is too scattered to determine the average force that is exerted on the object.
No, because the student needs to know the direction that the force is applied to the object because the applied force will be in the same direction as the change in momentum of the object.
Answer:
D. No, because the student needs to know the direction that the force is applied
Explanation:
The change in momentum depends on the direction of the force as well as its magnitude. Since the graph only supplies force magnitude information, it is insufficient to allow the student to calculate the change in momentum.

Explanation:
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

Convert 1 mm to meters using scientific notation. Include units in your answer.
Answer: The answer in scientific notation with the unit included is (1 × 10^-3m.)
Explanation:
In the field of physics, when working with too large or too small numbers, such can be expressed with the use of scientific notation. This helps to eliminate huge or ambiguous numbers with significant units. It is written is such a way that the first number is greater than or equal to 1 and less than 10 which is then multiplied by a factor of 10.
Units are symbols that are used to represent a measurement For example the unit of meters is (m).
Converting 1mm to m:
1000millimeters = 1meter
1 millimetre = X
Making X the subject of formula,
X = 1 ×1 /1000
X = 0.001m
Therefore expressing X in scientific notation is
1 × 10^-3meter (m)

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
Which three statements about gravity and the formation of the solar system
are true?
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

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.
