Answer:
1.0.024 hp
Step-by-step explanation:
We are given that
Constant force=F=112 N
Speed of lawn mower,v=20 cm/s=
1 m=100 cm
1 hp=746 watt
We have to find the power output
Force applied by women on lawn mower=
Force applied by women on lawn mower=N
Power output,P=
Using the formula
Power output=
Power output,P=hp
Hence, option 1 is true
u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,
⇒
⇒
⇒
⇒
⇒ u = 10.4
Hence, u = 10.4 and v = 12.
