Answer:
option A
Explanation:
given,
Kinetic energy of the car = 2000 J
speed of the car is doubled
we know,

 ........(1)
........(1)
now, speed of the car is doubled
v' = 2 v


from equation (1)



Hence, the Kinetic energy would be equal to 8000 J.
The correct answer is option A.
 
        
             
        
        
        
Answer:(a) 50 N
(b)38.34 N
Explanation:
Given
Maximum tension(T) in line 50 N
(a)If line is moving up with constant velocity i.e. there is no acceleration
This will happen when Tension is equal to weight of Fish
T-mg=0
T=mg
Maximum weight in this case will be 50 N
(b)acceleration of magnitude 
T-mg=ma


m=3.91
Therefore weight is 
 
        
             
        
        
        
Answer:
ventriculoperitoneal       
Explanation:
A VP or ventriculoperitoneal shunt is a medical equipment or a device which is used to relieve pressure from the brain that is caused by the accumulation of fluid in the brain. Ventriculoperitoneal shunting is a medical procedure that is primarily used to treat a condition  known as hydrocephalus. This condition occurs when the more cerebrospinal fluid (CSF) gets collected in the  ventricles of the brain than required. 
Hence the answer is ---
ventriculoperitoneal       
  
        
             
        
        
        
Answer:
Energy stored at 12 volt will be 115.2 J and energy stored at 24 volt will be 460.8 volt
Explanation:
We have given capacitance of capacitor C = 1.6 F
Normal voltage V = 12 volt 
And system uses 2 volt to charge the system 
We know that energy stored in the capacitor is equal to 
So energy stored at 12 volt will be equal to 
And energy stored at 24 volt will be equal to 
So energy stored at 12 volt will be 115.2 j and energy stored at 24 volt will be 460.8 j
 
        
                    
             
        
        
        
Answer:
Explanation:
Fill the graduated cylinder partially with water to a level where you can submerge the object and drop the sinker weight into the water. If you don't have a graduated cylinder to fit your object, put a cylinder in a basin, fill it to the top with water and measure the overflow into the basin. Your answer will be less accurate because of the number of times the water has been moved. Note the amount of displacement in milliliters (ml) caused by the sinker and string.
Measure the mass of your object (say a cork) on a balance scale in grams (g). Be sure the object is dry when it is measured. Record its weight. Attach the sinker with the string to the object. If you use a staple or pin, be sure to include that when you measure the displacement of the sinker in step one.
