Answer:
Option d.
Explanation:
The asteroid belt is a stellar disc which exists in between Mars and Jupiter's orbits which consists of a large no. of asteroids in our solar system.
the asteroids in the asteroid belt are formed from different regions and those asteroids with the similar chemical properties or compositions form a group and the different groups formed on these basis are distant from each other with some gap called as kirkwood gap. The gaps so formed are in resonance with Jupiter and are influenced by the strong gravitational force of Jupiter which renders them unstable in the region of resonance which prevents planet formation.
Answer:
effective dose is 1.2 mrem
Explanation:
given data
mass m = 70 kg
absorb n = 4.5 × 
energy = 1.2 MeV
neutrons = 10
to find out
equivalent dosage
solution
we know here total energy in a day is
total energy = 4.5 × × 1.2
total energy = 5.4 × 
eV
and total energy = 5.4 × × 1.6 × 
so total energy = 8.64 × 
J
and for mass 70 kg
it will be = 8.64 × / 70
= 1.23 × 
rad
so
effective dose is here = 1.23 × × 10 = 0.0012 rem
so effective dose is 1.2 mrem
Voltage=Energy/Charge, V=E/Q
V in volts V, E in joules J, Q in coulombs C.
or
Voltage= Current×Resistance, V=IR
V in volts V, I in amperes A and R in ohms Ω
Newton also understood that white light can be separated into its components because each ray of color is deviated by the glass of the prism by a different amount. He realized, for example, that red light is consistently less deviated than violet light.
