Answer:The kinetic energy of the water molecules decreases. ... The motion of the particles in the substance decreases, and the temperature of the substance increases.
Explanation:
Answer:
15 m/s
Explanation:
Given data
Initial velocity= 0m/s----------since the cart was at rest
Final velocity = 30m/s
time= 30 seconds
Required
the average speed
We know that the sum of the initial and final velocity is divided by 2 to find the average velocity
average velocity= 0+30/2
average velocity= 30/2
average velocity= 15 m/s
Hence the average velocity is 15 m/s
Self productive and it depends on how whom is behaving.
• Objects “fall” toward the center of Earth. (TRUE)
Since the gravitational force between earth and any object is always along the line joining the centers of two so all the objects near the surface of earth will always feel force towards the centre of the earth due to gravity.
• Objects are pulled by Earth but do not pull on Earth. (FALSE)
Since gravitational force will always follow Newton's III law as per which every action has equal and opposite reaction force so object near the surface of earth will also pull the earth as earth is pulling the object towards the center.
• Objects accelerate at a rate of 9.8 m/s each second. (TRUE)
Since acceleration due to gravity of Earth is 9.8 m/s^2 so here we can say that all objects near the surface of earth will accelerate towards the center of earth at rate of 9.8 m/s^2 due to gravitational pull.
• Objects travel at a rate of 9.8 m/s to are the center of Earth. (FALSE)
Since earth is pulling all objects near its surface with gravitational force so objects can not move at constant speed but it will move with constant acceleration.
• Objects are pulled by Earth more strongly than they pull on Earth. (FALSE)
Since gravitational force will always follow Newton's III law which say every action has equal and opposite reaction so we can say that force due to all objects on earth will be same as the force of earth on the object.
Answer: Move the small car so it appears on the left side of the lens.
Explanation:
Because the lens is reflective the small car would apear on the same side as the normal car.
Hope this helps :)
