Answer:
The oven has many different heat sources from the bottom, sides, top, etc... 
The microwave only has the sides.
 
        
             
        
        
        
1 pound ≈ 0.4536 kg
170 pounds ≈ 170 * 0.4536 kg
                     ≈ 77.112 kg
                       
        
             
        
        
        
The power in horsepower is 40.1 hp
Explanation:
We start by calculating the work done by the airplane during the climb, which is equal to its change in gravitational potential energy:

where
mg = 11,000 N is the weight of the airplane
 is the change in height
 is the change in height
Substituting,

Now we can calculate the power delivered, which is given by

where
 is the work done
 is the work done
 is the time taken
 is the time taken
Substituting,

Finally, we can convert the power into horsepower (hp), keeping in mind that

Therefore,

Answer : The correct option is, (C) 17 m/s
Explanation :
Formula used :

where,
K.E = kinetic energy = 6.8 J
m = mass of object = 46 g = 0.046 kg    (1 kg = 1000 g)
v = velocity
Now put all the given values in the above formula, we get:




Therefore, the ball's velocity be as it leaves the cannon is, 17 m/s
 
        
             
        
        
        
If the ground is flat, and both bullets are released at the same time from the same height, then they both hit the ground at the same time.
The horizontal motion of the one from the gun has no effect on its vertical motion.
