Essay

(2a)
H=ut+½gt²
Where H=80m, t=?
80=0(t) + ½(10)(t²)
80=0 + 5t²
80=5t²
80/5=t²
16=t²
t=√16
t=4s

(2b)
Range = U²/g
20²/10
=400/10
=40m
====================================
(3)
F = KAV/L
FL = KAV
K = FL/AV
Where F = ma
= MLT-²
r = M, V = LT-¹
And A = M²

K = MLT-² × M/m² × LT-¹
K = LT-² ×L-¹T-¹
K = T-¹
====================================
4i) Conduction of heat : This is the process by which heat is passed along a metal object from one particle at higher temperature to another lower temperature without the heated particle appearing to move

4ii) Convection : This is the process by which heat energy is transferred in a fluid by actual movement of the heated particle

4iii) Radiation : This is the process by which heat is transferred from it’s source to the body absorbing it without heating the intervening medium
====================================
(5)
(i)by colour
(ii)by nature of substance
(iii) by conductivity
====================================
6a) Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.

6b)
i) Iron
ii) nickel
iii) cobalt
====================================
8ai)Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. … Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ​1⁄760 of this

8ii)
i) They are the depth of the fluid and its density.
ii) A fluid exerts more
pressure at greater depths
====================================
9ai) A thermometric substance is any substance whose physical or chemical properties changes with a change in temperature

ii)
i) Mercury
ii) Alcohol

iii)
a)Has a thin wall-it has a thin wall in order to easily detect slight temperature changes
b) Small-it is small in order tp enhance uniform distribution of heat in the liquid

(2a)
H=ut+½gt²
Where H=80m, t=?
80=0(t) + ½(10)(t²)
80=0 + 5t²
80=5t²
80/5=t²
16=t²
t=√16
t=4s

5)
1.temperature of body
2.temperature of surroundings
3.area of body
4.material of body

*Pick 3*

====================================
6a) Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.

*6b*) 1Iron,

2 nickel,

3cobalt

Pick only 2

====================================
8ai)Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. … Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ​1⁄760 of this

8ii)
i) They are the depth of the fluid and its density.
ii) A fluid exerts more
pressure at greater depths
====================================

12a.) Natural radioactivity in the environment originates from two sources. First, primordial radionuclides which were incorporated into the Earth at the time of its formation are still present in it because of their long half-lives. 238U, 235U, 232Th and their decay series (Figure 1), 40K, 87Rb and 187Re are examples of this category. Second, cosmic ray-produced isotopes which are generated continuously in the atmosphere and earth’s crust through interactions of cosmic rays with their constituents.

(12a)
Thermoelectrons are electrons emitted at a high temperature such as one produced in a thermionic valve. They are negatively charged.

(12b)
(i) Low voltage battery
Used to heat the heater or heating element.
(ii) Target metal
Used to collect the emitted electrons.

(12Ci)
α – particles has a helium nuclei He while a β-particle has high energy electrons.

(12Cii)
α – particle has a charge of +2e while β-particle has a charge of -e.

(12di)
The radioactive decay law states that the probability per time that a nucleus will decay is constant, independent of time.

(12dii)
(i) Damage to skin.
(ii) Causes cancer.

(12ei)
Given 238 U –> m X + 2α
92 n
= 238 U –> m X + 2 4He
92 n 2
m+(2×4) = 238
m + 8 = 238
m = 238 – 8 = 230
Also
N + (2×2) = 92
N + 4 = 92
N = 92 – 4
n = 88

(12eii)
230
X
88

No of neutrons = 230 – 88 = 142
Neutron – Proton ratio = 142/88 = 1.61

(12eiii)
It is unstable.
