Total displacement along the length of mountain is given as
L = 235 m
angle of mountain with horizontal = 35 degree
now we will have horizontal displacement as
x = L cos35
x = 235 cos35 = 192.5 m
similarly for vertical displacement we can say
y = L sin35
y = 235 sin35 = 134.8 m

North and east are perpendicular directions hence we can use them as the basis of our coordinate system. The coordinates of this point can then simply be represented as
P = 1.4 N + 4.8 E (km)
The magnitude can be given by the right triangle formula :
P = 
= 5 km
Direction = atan(N/E) = 16.3 deg north of east = 73.7 deg east of north

<h3><u>Answer</u>;</h3>
Price floor
When the government sets a price for wheat that is above the equilibrium price, it is imposing a<u> price floor</u>.
<h3><u>Explanation</u>;</h3>
- <u>Price floors prevent a price from falling below a certain level. When a price floor is set above the equilibrium price, quantity supplied will exceed quantity demanded, and excess supply. </u>
- <u>Price control </u>occurs when the government laws regulate prices instead of letting market forces determine prices.
- <u>Price ceilings</u> prevent a price from rising above a certain level.
Answer:
Few millimeter thick aluminium, water, wood, acrylic glass or plastic.
Explanation:
The materials that are best for protection against beta particles are few millimeter thickness of aluminium, but for the high energy beta-particles radiations the low atomic mass materials such as plastic, wood, water and acrylic glass can be used.
These materials can also be used in personal protective equipment which includes all the clothing that can be worn to prevent any injury or illness due to the exposure to radiation.
