the answer will be true
cut down trees surrounding his fields
plant trees around the perimeter of his fields
irrigate his fields during dry seasons and droughts
Answer: Option (c) is the correct answer.
Explanation:
In order to reduce the velocity of wind there should be some placed some barrier near the field. So that when fast moving wind strikes at the surface of barrier then its speed will decrease.
Therefore, the farmer Wilcox should plant trees around the perimeter of his fields which will act as a barrier to the fast moving winds.
Answer:
Speed of train = 60 km/hr
Speed of plane = 160 km/hr
Explanation:
We can construct the following equations from the given information:
Speed of train * time = 150 -Equation 1
Speed of plane * time = 400 -Equation 2
Speed of plane = (3 * Speed of train) - 20 -Equation 3
We can solve these three simultaneous equations for the three variables (speed of train , speed of plane, time).
Substituting within Eq. 1 and Eq. 2 we get:
Speed of plane * 150 = 400 * Speed of train -Equation 4
Finally, solving Eq. 4 and Eq. 3 simultaneously we get:
Speed of train = 60 km/hr
Speed of plane = 160 km/hr
a. True
b. False
30min=30/60hr=0.5hr
velocity=distance/time=10mile/0.5hr=20 miles per hour East
There are 60 minutes in an hour so 30 minutes is 0.5 hour.
Velocity is equal to displacement / time
= 10 miles East / 0.5 hour
= 20 miles per hour East
