Answer:
a) 0.069 acres
b) 0.114acres
c) 17.78acres
Explanation:
1 dot=1/36sqin
a) 1 sqin= 330×330=108900ft^2
1 dot=108900/36 =3025ft^2
Converting to acre,divide by43560
3025/43560 =0.069acre
b) 1 chain =22 yards
25×22=550yards
Converting to acre divide by 4840
550/4840 =0.114acre
c)1 sqmile =640acres
(1/36) ÷ 640
640/36
17.78acres
Answer:
v=10 m/s
Explanation:
Given that,
Speed of a drone is 8 m/s due East with respects to the wind
Speed of a drone 6 m/s due North with respect to the ground.
We need to find the speed of the drone with respect to the ground. Let v is the speed. It is given by the resultant of two speeds.

So, the speed of the drone with respect to the ground is 10 m/s.
Answer:
yeah righto the correct answer mate would be D) :)
Answer:
False
Explanation:
A Larger pulse with more energy means that the wave has a large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain the same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels.
