Answer:
So to increase current of the circuit what you can do is :
1. Use conductor of low resistivity, ¶.
2. Use conductor of small length.
3. Use thick wire.
4. Decrease the temperature of the circuit.
5. If operating temprature is high than use semiconductor, because it have negative temprature coefficient.
6. Minimise the circuit losses.
It is because carbon dioxide traps the solar radiation which then warms up the atmosphere, not allowing the radiations to get deflected back in the outer space.. that's what is happening to our own planet the greenhouse effect.. which is also increasing the GLOBAL Temp of our planet too
Answer:
The speed of these waves is 222.22 m/s
Explanation:
A.
Since, we know that the speed of a wave is given by the formula:
v = fλ
where,
v = speed of wave
f = frequency of wave
λ = wavelength
Here,
λ = distance between consecutive wave crests
λ = 800 km = 8 x 10⁵ m
f = 1/Time Period = (1/1 hr)(1 hr/3600 s)
f = 2.77 x 10⁻⁴ s⁻¹
Therefore,
v = (2.77 x 10⁻⁴ s⁻¹)(8 x 10⁵ m)
<u>v = 222.22 m/s</u>
Speed of the wave is equal to
frequency*wavelength
200*3 = 600m/s
<span>The force due to the magnetic field generates a centripetal force on the proton.
F = qvB = mv^2/r
qB = mv/r
qB = p/r
kinetic energy (K) = mv^2/2 = p^2/(2m)
qB = </span>√<span>(2mK) / r
r = </span>√<span>(2mK) / (qB)
r = </span>√<span>[(2)(1.67e-27 kg)(5.0 MeV * 1.60e-13 J/MeV)] / [(1.60e-19 C)(0.20 T)]
r = 1.6 m</span>
