A dog walks 8.0 meters due north and then 6.0 meters due east. Determine the magnitude of the dog's total displacement to the ne
Rus_ich [418]

Answer:

the magnitude of the dog's total displacement to the nearest tenths = 53.12°

Explanation:

Given that:

a dog walks 8.0m due to the north and 6.0 m due east.

We can determine the magnitude of the dog's total displacement by using the Pythagoras theorem.

Consider the north direction be the opposite and the east direction to be the adjacent, therefore the hypotenuse will be the dog's total displacement.

So, suppose hypotenuse is represented by a

the opposite represented by b, and the adjacent represented by c

Then;

a² = b² + c²

a² = 8²  +  6²

a² = 64 + 46

a² = 100

a =\sqrt{100

a = 10.0 m

However, the magnitude of the dog's total displacement is calculated by taking the tangent of the system.

tan θ = opposite / adjacent

tan θ = b/c

tan θ = 8/6

tan θ = 4/3

tan θ = 1.333

θ = tan⁻¹ (1.333)

θ = 53.12

the magnitude of the dog's total displacement to the nearest tenths = 53.12°

Cindy exerts a force of 40 newtons and moves a chair 6 meters. Her brother Andy pushes a different chair for 6 meters while exer
sesenic [268]
Work formula:
W = F * d
F 1 = 40 N, d 1 = 6 m;
F 2 = 30 N; d 2 = 6 m.
W ( Cindy ) = 40 * 6 = 240 Nm
W ( Andy ) = 30 * 6 = 180 Nm
The difference of their amounts if work:
240 Nm - 180  Nm = 60 nm

hope it helps!
