Answer: 1 microgram is equal to 0.001 miligrams
Explanation: The factor micro is equal 10^-3 while the factor mili is equal to 10^-3 so to converte the micro to mile we have to multiply by 0.001.
B. Ultraviolet light waves
C. Infrared Waves
D. Microwaves
The heat emitted from anything is carried in the form of infrared waves. (C)
Answer:
x(t) = 20t + 12.75e⁻¹•⁶ᵗ + 487.5
t = 24.375 s
Explanation:
The force balance on the object is given as
Net force = W - Drag force
ma = W - 10v
a = (dv/dt)
ma = m(dv/dt) = 200 - 10v
W = mg
200 = m×32
m = 6.25 kg
m(dv/dt) = 200 - 10v
6.25(dv/dt) = 200 - 10v
(dv/dt) = 32 - 1.6v
v' + 1.6v = 32
Solving this differential equation using the integrating factor method
(ve¹•⁶ᵗ) = ∫ (32e¹•⁶ᵗ) dt
ve¹•⁶ᵗ = (20e¹•⁶ᵗ) + c (where c = constant of integration)
v = (20 + ce⁻¹•⁶ᵗ)
At t = 0, v = 0
0 = 20 + c
c = -20
v = (20 - 20e⁻¹•⁶ᵗ)
v = (dx/dt)
(dx/dt) = 20 - 20e⁻¹•⁶ᵗ
dx = (20 - 20e⁻¹•⁶ᵗ) dt
x(t) = 20t + 12.5e⁻¹•⁶ᵗ + c (c is still the constant of integration)
At t = 0, x = - 500
- 500 = 0 + 12.5 + c
c = 512.5
x(t) = 20t + 12.75e⁻¹•⁶ᵗ - 487.5
when the object hits the ground, x = 0
0 = 20t + 12.75e⁻¹•⁶ᵗ - 487.5
20t + 12.75e⁻¹•⁶ᵗ = 487.5
Solving by trial and error,
t = 24.375 s

Answer:
Part a)
Part b)
Yes it is the expected value of electric field at the surface of an atom
Part c)
Explanation:
Since negative charge of electrons in uniformly distributed in the atom while positive charge is concentrated at the nucleus
So the electric field due to positive charge of the nucleus is given as
now charge due to electrons inside a radius "r" is given as
now we will have electric field given as
now net electric field is given as
Part b)
At the surface of an atom
Yes it is the expected value of electric field at the surface of an atom
Part c)
If Z = 92
R = 0.10 nm
so we will have

Answer:
15N
Explanation:
F¹=150N
A=0.01m2²
F2=?
A2=0.1m²
P=F/A
F1/A2=F2/A1
150/0.1=F2/0.01
