Using the precise speed of light in a vacuum (

), and your given distance of 

, we can convert and cancel units to find the answer. The distance in m, using 

, is 

. Next, for the speed of light, we convert from s to min, using 

, so we divide the speed of light by 60. Finally, dividing the distance between the Sun and Venus by the speed of light in km per min, we find that it is 
6.405 min.
 
        
        
        
The solution for the problem is:
1 Watt = 1 Joule per second 
1 Watt*second = 1 Joule 
a Kilowatt is 1,000 Watts 
an hour is 60 seconds times 60 minutes or 3,600 seconds 
a Kilowatt * hour is 1,000 Watts in 3,600 seconds 
15 W*h = 15,000 Watt*hour = 15,000 Watt * 3,600 seconds = 54,000,000
Watt*second 
54,000,000 Watt*second = ? Joules 
54,000,000 Joules / second = 54,000,000 Watts

Answer:
t=2.10 s
u= 47.40 m/s
Explanation:
given that
h= 21.8 m
x= 101 m
g=9.8 m/s²
Lets take horizontal speed of  ball = u m/s
The vertical speed of the car at initial condition is zero ( v= 0).
We know that

v= 0 m/s

now by putting the values
21.8 = 1/2 x 9.8 x t²
t=2.10 s
This is time when ball was in motion.
Now in horizontal direction
x = u .t
101 = u x 2.1
u= 47.40 m/s
 
        
             
        
        
        
Answer:
 initial magnetic field  1.306 T
Explanation:
We have given area of the conducting loop 
Emf induced = 1.2 volt 
Initial magnetic field B = 0.3 T
Time dt = 0.087 sec
We know that induced emf is given by 


So initial magnetic field = 1.606-0.3= 1.306 T
