“Weathering is the breaking down of rocks, soil and minerals as well as wood and artificial materials through contact with the Earth’s atmosphere, biota and waters. Weathering occurs in situ, roughly translated to: “with no movement”, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.”
Weathering processes are of three main types: mechanical, organic and chemical weathering.
Answer:
The building was moved to a distance of, S = 510.2 m
Explanation:
Given data,
The mass of the building, m = 1.45 x 10⁶ kg
The work done to overcome the force of resistance, E = 1 x 10⁸ J
The force of resistance of the building, 2% of building weight
Fₓ = 2 x 1.45 x 10⁶ x 9.8 / 100
= 284200 N
The work done on the building,
E = Fₓ · S
∴ S = E / Fₓ
= 1.45 x 10⁶ / 284200 N
= 510.2 m
Hence, the building was moved to a distance of, S = 510.2 m
Answer:
Explanation:Standing flood waters can also spread infectious diseases, contain chemical hazards, and cause injuries. Each year, flooding causes more deaths than any other hazard related to thunderstorms. The most common flood deaths occur when a vehicle is driven into hazardous flood waters.
Answer: The height of the cloud = 394.55 m
Explanation:
The observer is 500m away from the spotlight.
Let x be the distance from the observer to the interception of the segment of the height, h with the floor. The equations are thus:
Tan 45° = h/x ... eq1
Tan 75° = h/(500- x ) ... eq2
From eq 1, Tan 45° = 1, therefore eq1 becomes:
h = x ... eq3
Put eq3 into eq2
Tan 75° = h/(500- h)
h = ( 500 - h ) Tan 75°
h = 500Tan 75° - hTan75°
h + h Tan 75° = 500 Tan 75°
h ( 1 + Tan 75° ) = 500 Tan75°
h = 500Tan75°/ (1 + Tan 75°)
h= 1866.02 / 4.73
h = 394.55m
