Answer:
Explanation:
Work done in carrying bricks 
mgh
= 207 x 9.8 x 3.65
-= 7404.4 J 
Work done in compressing gas
PΔV 
Pressure x change in volume 
1.8 x 10⁶ ΔV = 7404.4 
ΔV  = 7404.4  / 1.8 x 10⁶m³
= 4113.33 x 10⁻⁶ m³
= 4113.33 cc 
 
        
                    
             
        
        
        
Because the tomato did not chemically changed it was only physically altered.
Hope this helps! :D
        
                    
             
        
        
        
Answer:
The final image relative to the converging lens is 34 cm.
Explanation:
Given that,
Focal length of diverging lens = -12.0 cm
Focal length of converging lens = 34.0 cm
Height of object = 2.0 cm
Distance of object = 12 cm
Because object at focal point
We need to calculate the image distance of diverging lens
Using formula of lens



The rays are parallel to the principle axis after passing from the diverging lens.
We need to calculate the image distance of converging lens
Now, object distance is ∞
Using formula of lens


The image distance is 34 cm right to the converging lens.
Hence, The final image relative to the converging lens is 34 cm.
 
        
             
        
        
        
Answer:
I'm pretty Sure. Yea look. 
Explanation:
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
 
        
                    
             
        
        
        
Answer:
Kinetic energy = 35840 Joules 
Explanation:
Given the following data;
Mass = 70kg
Velocity = 32m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion. 
Mathematically, kinetic energy is given by the formula;

Where, K.E represents kinetic energy measured in Joules. 
M represents mass measured in kilograms. 
V represents velocity measured in metres per seconds square. 

Substituting into the equation, we have;



K.E = 35840 Joules. 
Therefore, the kinetic energy possessed by the cheetah is 35840 Joules.
