To calculate the mass of the fuel, we use the formula

Here, m is the mass of fuel, V is the volume of the fuel and its value is  and
 and   is the density and its value of  0.821 g/mL.
 is the density and its value of  0.821 g/mL.
Substituting these values in above relation, we get  
 
 
Thus, the mass of the fuel 247 .94 kg.
 
        
             
        
        
        
Answer:

Explanation:
The period of the simple pendulum is:

Where:
 - Cord length, in m.
 - Cord length, in m.
 - Gravity constant, in
 - Gravity constant, in  .
.
Given that the same pendulum is test on each planet, the following relation is formed:

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

Answer:
cold cathode fluorescent lamp
Explanation:
A cold cathode fluorescent lamp (CCFL) is a lighting system that uses two phenomena: electron discharge and fluorescence.
CCFLs are mainly used as light sources for backlights, since they are compact and durable than ordinary fluorescent lamps. They exhibit a wide range of brightness and color (color temperature and chromaticity) that can be achieved by varying the pressure and type of the material injected into the glass tube. The thickness and type of the phosphor used to coat the inner wall of the tube also plays a role in altering the color and brightness.
 
        
             
        
        
        
Mass of bottle + cooking oil = 1.3 kg
Mass of bottle + 1/2 cooking oil = 0.9 kg
Thus half cooking oil = 1.3 - 0.9 
                                  = 0.4 kg
Mass of cooking oil in a full bottle = 0.4 × 2
                                                      = 0.8 kg
Therefore the mass of the empty bottle
               = 1.3 - 0.8 
               = 0.5 kg
