Answer
m/s rate of change of dispalcement per sec. ie velocity
m/s^2 is (m/s)/s ie rate of change of velocity per sec. ie accelerationplanation:
 
        
                    
             
        
        
        
Answer:

Explanation:
we know angular velocity in terms of moment of inertia and angular speed 
         ω ....                        (1)
ω ....                        (1)
moment of inertia of rod rotating about its center of length b
  
          ........               .(2)
  ........               .(2)  
using         v = ωr  
where w is angular velocity 
and r is radius of  rod which is equal to b 
         so we get  2v =  ωb  
                             ω  = 2v/b  .................            (3)    
here velocity is two time because two opposite ends  are moving opposite with a velocity v  so net velocity will be 2v
put second and third equation in ist equation 
                   ×
× 
 
                so final answer will be      
 
        
             
        
        
        
Answer:
For C1, Q =  1.6125×10⁻³ C
For C2, Q =  6.25×10⁻⁴ C 
Explanation:
Note: Since the capacitors are connected in parallel, The voltage across each of them is equal.
From the question,
Q = CV........................ Equation 1
Where Q = Charge on the capacitor, V = Voltage across the capacitor, C = Capacitance of the capacitor.
For the first capacitor,
Q = C1V............. Equation 2
Where C1 = 6.45 μF= 6.45×10⁻⁶ F, V = 250 V
Substitute into equation 2
Q = (6.45×10⁻⁶ )(250)
Q = 1.6125×10⁻³ C.
For the the second capacitor,
Q = C2V............. Equation 3
Given: C2 = 2.50 μF = 2.5×10⁻⁶ F, V = 250 V
Q = (2.5×10⁻⁶ )(250)
Q = 6.25×10⁻⁴ C

Answer:
Taking water and oxygen from Earth is rather expensive and hard to do. 
Explanation:
Without water and oxygen, travel to other planets is basically impossible
