Virty [35]2 years ago
5 0

Answer:

Sin θ = θ     is a useful approximation up to about 10 deg

Sin 10 = .174

10 / 360 * 2 π = .175      where 2 π = 360 deg in a circle (no of radians)

Catalytic ozone destruction occurs in the stratosphere by a two-step reaction:
Sladkaya [172]
Catalytic ozone destruction occurs in the stratosphere where the reactions involving bromine, chlorine, hydrogen, nitrogen and oxygen gases form compounds that destroy the ozone layer. The reactions uses a catalyst (speeds up the reaction) in a two step reaction. considering chlorine the reactions appears as follows;
step 1
 Cl + O3 = ClO + O2 
 step 2
ClO + O = Cl + O2 
Where by chlorine is released to destroy the ozone layer, this takes place many times even with the other elements (hydrogen, bromine, nitrogen) and the end result is a completely destroyed Ozone layer

An Airbus A380 airliner can takeoff when its speed reaches 80 m/s. Suppose its engines together can produce an acceleration of 3
Tomtit [17]

Answer:

(a). The time is 26.67 sec.

(b). The distance traveled during this period is 1066.9 m.

Explanation:

Given that,

Speed = 80 m/s

Acceleration = 3 m/s

Initial velocity = 0

(a). We need to calculate the time

Using equation of motion

v = u+at

t = \dfrac{v-u}{a}

Put the value into the formula

t = \dfrac{80-0}{3}

t =26.67\ sec

The time is 26.67 sec.

(b). We need to calculate the distance traveled during this period

Using equation of motion

s = ut+\dfrac{1}{2}at^2

s = 0+\dfrac{1}{2}\times3\times(26.67)^2

s =1066.9\ m

The distance traveled during this period is 1066.9 m.

Hence, This is the required solution.

lapo4ka [179]

Answer: C) By collecting run off during the rainy season for future irrigation increases the agricultural production

Explanation:

Water harvesting is a process of collection of rain water by using special water storing systems. This water storage practice helps during the scarcity of water like in dry summer seasons and in conditions of drought. Such water can be treated with filters to make it potable for drinking. But generally the water is used for the purpose of irrigation in the agricultural field and household sanitary requirements.

On the basis of the above description, By collecting run off during the rainy season for future irrigation increases the agricultural production is the correct option.
