Taking right movement to be positive means leftward movement is negative.
Hence we have a deceleration of
Using this 'suvat' equation
we can determine the initial velocity
Hence the initial velocity is 13.0 meters per seconds
Explanation:
I want to say option B - Both forces can act without objects touching.
Answer:
The acceleration is constant and positive
Explanation:
The straight line indicates that the acceleration is constant, while the positive slope indicates that the line is positive.
Convection is the transfer of heat through a fluid
Conduction is the heat or electric current from one substance to another
Radiation is energy that radiated or transmitted
Ex: Convection- A pot of water is being boiled- the heat is being transferred to to the water
Ex2: Conduction- I have a plate filled with hot food- the heat from the food is being transferred to the plate, making the plate hot as well.
Ex3: Radiation- There is a dog by the fire place, the dog is being warmed- the heat from the fire is being transferred over to the dog
Hope this will help you with your homework :)
