Answer:
Given that
capacitor being charged by a current i c has a displacementcurrent equal to i c between the plates∴
displacement current iD =i c=0.280 Aradius of the circular plate r = 4 cm=0.04 m
( A ) . displacement current density j D = iD / ( π r 2 )=0.28 / ( 3.14 * 0.04 2 )=55.73 A / m 2
( B ) . displacement current density j
D = ε( dE / dt )the rate at which the electric field between the plates is changing(
dE / dt ) = jD/ εdE/ dt ) = 55.73/ 8.85 * 10 -12=6.3*10 12 N / C - s( C ) . the induced magnetic field between theplates B = ( μ * r / 2π R 2) * i c ----( 1 )whereR= 2 cm=0.02 mr= 4 cm=0.04 mμ=permeability of free space=4π* 10 -7 H( D )substitute R = 1 cm = 0.01 m inequation ( 1 ),wegetanswer
If you increased the speed of rotation of the Earth you would get a perceived decrease in the weight of the object due to an increased centrifugal force.
Increase it fast enough and the momentum of the object will eventually overcome the gravitational pull on it and it will fly off the planet.
Answer:
ammonia can be produced at ambient pressure from, air water and concentrated sunlight as a renewable source of process heat via nitrogen reduction with a looped metal nitride followed by separate hydrogenation of the lattice nitrogen into ammonia

Answer:
Please see answer below
Explanation:
The uncertainty will depend of the granularity of the instrument you use for the measurement.
For example, if you measure the length of a tabletop with a measuring tape with the smaller divisions given by the mm for example,then your measurement is limited by 1 mm (it cannot be better than that because your instrument doesn't have a finer division)
If you are using a digital scale to measure the weight of an object for example, and the scale displays in the readout 26.3 grams, then your uncertainty becomes 0.1 gram because that is the best your scale can read.
If on the other hand your scale reads no better than the gram, and gives you just 26 in the display, then the resolution of the scale is 1 gram, and that is what the uncertainty in your measurement is.
You have to report it as: 26 ± 1 g
Answer:
6000 N
Explanation:
Newton's third law states that:
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
In this problem, we can identify:
- The truck as object A
- The car as object B
This means that if the force exerted by the truck on the car (the action) is 6000 N, then the force exerted by the car on the truck (the reaction) must also have equal magnitude, 6000 N, and be in the opposite direction.
