Answer:
170 N
Explanation:
The following data were obtained from the question:
Mass (m) = 20 Kg
Angle (θ) = 30°
Acceleration due to gravity (g) = 9.8 m/s²
Weight (W) =?
The perpendicular component of the weight can be obtained by using the following formula:
W = mg × Cosθ
W = 20 × 9.8 × Cos 30
W = 196 × 0.866
W = 169.7 ≈ 170 N
Therefore, perpendicular component of the weight is 170 N
<u>The number of variations the dealership have is 40 cars</u>.
Data given;
- The number of different product = 4
- The number of transmission = 2 (standard or automatic)
- The numbers of colors available = 5
<h3>Dealership variation </h3>
This is the total numbers of cars available in the dealer shop at the moment.
To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.
This is equal to
From the above calculation, we can say that <u>the variations the dealership offers is 40</u>

The work done in lifting an object to a height of 2 m is equal to two times the weight of the object. W = 2×mg
<h3>
Explanation:</h3>
Consider the mass of object to be m kg. The amount of work done to lift an object depends on the force required and the distance to which force is applied. To lift the object to a height of 2 m; Let F be the amount of force applied.
..................(1)
Where,
W=Work done
F= Amount of applied force
h=Height to which object is to be lifted
Applied force is equal to the weight of the object. Therefore,
..............(2)
Where,
m=Mass of the object
g=gravitational acceleration
Substituting (2) in (1), we get
For height = 2 m,
The work done in lifting an object to a height of 2 m is equal to twice the weight of the object.
