Answer:
Explanation:
It is given that,
Electric field due to the spark,
Dimensions of the parallel-plate capacitor is 5.1 cm × 5.1 cm.
The area of the parallel plate,
The electric field due to the parallel plate capacitor is given by :
Let n is the number of electrons that must transferred from one plate to the other to create a spark between the plates. It can be calculated as :
So, the number of electrons must be transferred from one plate to the other is . Hence, this is the required solution.
Answer:
yes
Explanation:
two people can push on one object at the same time.
The answer in this question is trellis in which define in this statement as the stream pattern which develops on lands underlain by the tilted or folded, alternating hard and soft and sedimentary strata is trellis. Trellis in architecture is an archintectural structure that is usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal.
Answer:
Therefore the magnitude of tangential velocity is 20 m/s.
Explanation:
Tangential velocity:The tangential velocity is the straight line velocity of at any point of rotating object.
It is denoted by
ω= angular velocity
r = radius of rotating object.
Angular velocity: Angular velocity is ratio of angle to time.
Here ω= 50 rad/s and r = 0.4 m
Tangential velocity=(50 ×0.4)m/s
=20 m/s
Therefore the magnitude of tangential velocity is 20 m/s.
Explanation:
Correct. Air has an index of refraction of approximately 1, and the angle of incidence is 35°. The substance has an unknown index of refraction n, and the angle of refraction is 25°.
1 sin 35° = n sin 25°
n = 1.36
