Answer:
Explanation: V = 3 cm/s = 0.03 m/s
BY THE FORmULA OF K.E
K.E = 1/2 mV^2
300 =1/2 m (0.03)^2
m = 300 x 2/0.0009
m= 666666.66kg
Answer:
The amount of charge at the center is -132.7 nC
Solution:
As per the question:
Electric flux from one face of cube, 
Edge, a = 19cm
Since, a cube has six faces, thus total flux from all the 6 faces = 
Also, from Gauss' law:
The stings vibrates around the air which makes a longitudinal wave
Answer:
L₀ = 15.12 fermi
Explanation:
From Einstein's special theory of relativity's consequence of length contraction, we know that:
L₀ = L √(1 - v²/c²)
where,
L₀ = Length of the object (electron) measured by observer at rest = ?
L = Length of the object (electron) measured by observer in relative motion
L = 10 fermi
v = relative speed = 0.75 c
c = speed of light
Therefore,
10 fermi = L₀√(1 - 0.75²c²/c²)
10 fermi = L₀√(1 - 0.5625)
10 fermi = L₀√0.4375
10 fermi/0.66 = L₀
<u>L₀ = 15.12 fermi</u>
No, Alec has not.
The force due to gravity is the same on all objects, regardless of shape and size. The acceleration caused by this force is 9.81 m/s². So if there are two identical pieces of paper, both will experience an equal force of gravity.
The difference in the papers' flight paths is due to the greater air resistance that the flat paper experiences. If the same experiment were to be repeated in a vacuum chamber, both of the pieces of paper would fall at the same rate
