Answer:
Explanation:
A uniform circular motion is an example of accelerated motion.
When an object is moving in a uniform circular motion, there is a centripetal force acting towards the centre of the circular path and then a centrifugal force is also acting away from the centre of the circular path. The magnitude of the centripetal force and the centrifugal force is same but the direction is opposite to each other. So, it is explained by the Newton's third law.
Answer:
Answer: Science and technology are relatively modern developments. For most of the past 50,000 years of civilization, there was religion, dogma, ritual an tradition. These kept civilization safe but prevented growth.
After the modern scientific method was developed during the Rennaisance, civil action took off.
Health, as expressed as life expectancies, has increased massively. Population growth has increased to levels thought impossible before. But yes, the environment has suffered.
In case they get affected by it
Answer:
A
Explanation:
Newton third law of motion state that action and reaction are equal and opposite
Answer:
B. Gravitational force
Explanation:
The gravitational force of an object (also called weight) is given by
where m is the mass of the object and g is the acceleration of gravity, and it always points in the downward direction.
In this problem, the arrow labelled with 4 is the only force pointing downward: therefore, it must be the gravitational force.
The other arrows represent:
1 --> component of the gravitational force parallel to the plane
2 --> force of friction
3 --> component of the gravitational force perpendicular to the plane
