Answer:
3525.19 kg
Explanation:
The computation of the mass of the car is shown below:
As we know that 
Fc = m × V^2 ÷ R
m = Fc × R ÷ V^2
Provided that:
Fc = 34.652 kN = 34652 N
R = Radius = 24.98 m
V = speed = 15.67 m/s
So,
m = 34652 × 24.98 ÷ 15.67^2
  = 3525.19 kg
 
        
             
        
        
        
This applies to nuclear reactions, specifically nuclear fission.
This huge release of energy has been used in atomic bombs and in the nuclear reactors that generate electricity.
        
             
        
        
        
Answer:
The answer to your question is below
Explanation:
Data
light speed = 300 000 km/s
a) Express it in scientific notation
to do it, we just move the decimal point 5 places to the left
          300 000 = 3.0 x 10 ⁵ km/s
b) Convert this value to meters per hour
   (300 000 km/s)(1000 m/1 km)(3600 s/1 h) = 300000x1000x3600 / 1x1x1
                                                                         = 1.08 x 10¹² m/h
c) What distance in centimeters does light travel in 1 s?
data
v = 300 000 km/s
d = ?
t = 1 s
  formula   v = d/t      we clear distance     d = vxt
                                   d = 300000 x 1 = 300000 km 
                                    d = 300000000 m = 30000000000 cm
 
        
             
        
        
        
4*5=20;  ration of 20:25, 
20/25= %80
