Answer:
E. downward and constant
Explanation:
Freefall is a special case of motion with constant acceleration because the acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.

The global warming is because of the car pollution was the fire in the forest it makes the air one and the warm air grocery Pacific side which makes me glacier it mostly glacier and breaks down two bases and the rising of the water makes the global warming too much so people are trying to use this card and try to use cycles because of global warming . 
l hope it helps you bro
        
             
        
        
        
When an object gets heated by a temperature ΔT energy needed, E = mcΔT
Here energy is given E = 2050 J
Mass of object = 150 g
Change in temperature ΔT  = 15  = 15 K
 = 15 K
a) Heat capacity of an object equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.
   So heat capacity = E/ΔT = 2050/15 = 136.67 J/K
b) We have E = mcΔT
                     c = 
  So object's specific heat = 911.11 J/kgK
 
        
             
        
        
        
Answer:
The magnetic force on the moving negative charge is towards the ceiling. 
Explanation:
The magnetic force acting on a wire is given by the relation as follows :

q is charged particle
v is velocity of charged particle
B is magnetic field
In this case, a negative charge is moving across a rook from south to north. A magnetic field runs from East to west.
q = -q
v =+j
B = -i
So,

Since, 
So,

So, the magnetic force on the moving negative charge is towards the ceiling.
