Answer:
c. Smaller than.
Explanation:
The energy stored in a capacitor is given as
E = 1/2CV²...................... Equation 1
Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = Voltage.
Also,
C = εA/d ......................Equation 2
Where ε = permitivity of the material, A = cross-sectional area of the plate, d = distance of separation of the plate.
substitute equation 2 into equation 1
E = 1/2εAV²/d ................. Equation 3
From equation 3 above,
The energy stored in a capacitor is inversely proportional to the distance of separation between the plates.
Hence when the plate is pulled apart by a distance D (D>d) The energy stored in the capacitor will be smaller.
The right option is c. Smaller than.
A transverse wave (electromagnetic wave) carries energy through space.
Explanation:
It is given that,
The acceleration of the toboggan, 
Initial speed of the toboggan, u = 0
We need to find the distance covered by the toboggan. Using the second equation of motion as :
At t = 1 s
At t = 2 s
At t = 3 s
Hence, this is the required solution.
Answer:
The right option is C. i.e L
Explanation:
Dimension of a quantity is the collection of the indexes of each of the fundamental quantities contained in it.
Therefore, to get the dimension of A in the equation
X=Asin(2(pi)ft)
Making A the subject of the formula
A = X / (sin(2(pi)ft)
Since sin(2(pi)ft which is a trigonometric function does not have a dimension
A = L
The dimension of A is L
Answer:
500 N
Explanation:
Because even if he lift one foot his weight will be same as the pressure applied on the scale will be the same and will not change it is not that the scale measures each foot separately
