Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.

Answer:
The potential difference between the plates is 596.2 volts.
Explanation:
Given that,
Capacitance 
Charge 
Separation of plates = 0.313 mm
We need to calculate the potential difference between the plates
Using formula of potential difference

Where, Q = charge
C = capacitance
Put the value into the formula


Hence,The potential difference between the plates is 596.2 volts.

Answer:

Explanation:
As we know that magnitude of two vectors is given as

here we know that
A = magnitude of vector A
B = magnitude of vector B
 = angle between two vectors
 = angle between two vectors
so here we know that
A = 30 units
B = 40 units
angle = 90 degree
so we have



 
        
             
        
        
        
Answer:
0.488  m  
Explanation:
If θ be the angle ladder makes with the plane 
cos θ = 1.2 / 5 
Tan θ = 4.04 
Let the height a person of weight 600 N  can climb be h from the ground . 
Distance from the base point  where ladder touches the floor  = h / tanθ
= h / 4.04 
Total reaction force = total downward force 
R = 200 + 600 
800 N 
Frictional force = μ R
= .2 x 800
= 160 N 
Taking moment of force about the point on the ladder  where it  touches the floor  and balancing them 
200 x 1.2 x .5 + 600 x   h / tanθ  = μ R x  1.2 / tanθ ( reaction  at the top point of ladder where it touches the wall is  R₁ and 
R₁ =μ R   )
= 200 x 1.2 x .5 + 600 x   h / tanθ  = 160 x 1.2 / tanθ
120  - 600 h / 4.04 = 47.52
120 - 47.52 = 600 h / 4.04
72.48= 148.51 h 
h = 0.488  m  
=
