Answer:
e)  J
 J 
Explanation:
 = Magnitude of electric field = 5 V/m
 = Magnitude of electric field = 5 V/m 
 = Area of window = 1.5 m²
 = Area of window = 1.5 m²
 = speed of electromagnetic wave = 3 x 10⁸ m/s
 = speed of electromagnetic wave = 3 x 10⁸ m/s 
 = time interval = 1 h = 3600 sec
 = time interval = 1 h = 3600 sec 
radiation energy is given as

Like windmills they use the winds to generate their power.
        
             
        
        
        
Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .
 
        
             
        
        
        
The correct answer is option A. i.e. An important thing to consider when responding to a driver in front of you that stops suddenly is: the mental state of the other driver.
Our talk or discussion can disrturb the balance of the driver or he can get distracted. So, we must try not to speak much while the driver is driving because by doing this we are putting the life of ourselves in danger. Any distrcaction of driver can cause accident.
