The mechanical advantage of a ramp that is 6.0 m long and 1.5 m tall. we can easily take any object to height of 6 m.
Gravitational potential energy is an energy acquired by an object due to a change in its height when it is present in a gravitationalfield. It is denoted by P or U. and it its expressed in joule. Gravitational potential energy is given by U = mgh where m is the mass of the object, g is acceleration due to gravity and h is the height.
when we take an object of mass m to a certain height in the field of gravitation, we can say that body has potential energy and we release that body from that height, it falls.
Ramp of 6.0 m long and 1.5 m tall is that there will be angle made by the inclination is 14.4°. Mechanical advantage of a ramp is, it is used for transportation of heavy objects to a certain height at certain distance. It reduces physical efforts and make our task faster. when we have to transport lots of object to a certain height, when we put objects on the ramp which has motor and upper part of the belt rotates, it will easily get transported to that height without physical efforts. Escalator is also a type ramp. Ramp which has no rotator, we have to push objects on the ramp to that height.
Hence these are advantages of a ramp.

Answer: 4.0
Explanation:
Speed of the motor cycle is given as
distance that he moved off from the ramp is given as
now we know that
now we can use this to find the height
so its height will be 75 cm from ground
The height of the ramp is approximately 0.748m.
To find the height of the ramp, we can use the equations of motion. Since the motorcycle leaves the ramp horizontally, the horizontal distance traveled is equal to the initial horizontal velocity multiplied by the time of flight.
Using the equation x = vt, where x is the horizontal distance traveled, v is the initial horizontal velocity, and t is the time of flight, we can solve for t.
For this problem, the horizontal distance is 40.0m and the initial horizontal velocity is 103m/s. Substituting these values into the equation, we get t = x/v = 40.0m / 103m/s = 0.388s.
Next, to find the height of the ramp, we can use the equation h = (1/2)gt^2, where h is the height of the ramp and g is the acceleration due to gravity (approximately 9.8m/s^2). Substituting the value of t we found into the equation, we get h = (1/2)(9.8m/s^2)(0.388s)^2 = 0.748m.

A - a hypothesis is a question a scientist wants to research
Explanation:
i think so anyway.
Answer:
Explanation:
AI-generated answer
A hypothesis is a statement that predicts what will be observed in an investigation. It is based on background research performed by the scientist and is usually written in an if-then format that describes the proposed relationship between variables. Therefore, all of the statements listed are true about hypotheses.
1. A hypothesis is a question a scientist wants to research.
2. A hypothesis is a statement that predicts what will be observed in an investigation.
3. A hypothesis is based on background research performed by the scientist.
4. A hypothesis is usually written in an if-then format that describes the proposed relationship between variables.
Since the question asks for an exception, it means that all of the statements are true.
The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
where, F - Force,
g - gravitational constant,
m₁ - mass of the object 1
m₂ - mass of the object 2
r² - distance between the two masses.
Gravitational attraction is along a line joining the centers of mass of these two bodies. The magnitude of the force is the same on each, consistent with Newton’s third law.
So, The law of gravity is an example of a universal law because Gravity is a force that exists between any to masses in the universe.
Hence, Option D is the correct answer.

Answer:
Yeah like the other answer D and A are kinda the same but i would pick D :p
Explanation:
Answer:
It is the SI unit of force.
Explanation:
The rate of change of momentum in the body is directly proportional to the force applied on the body. It is the second law of motion.
The mathematical form of Newton's second law is
F = m x a
where, m is the mass and a be the acceleration.
If a body of mass 1 kilogram having an acceleration of 1 m/s^2, it means the force applied on the body is 1 newton.
