The tension in the horizontal cord is 30N. Find the weight of the object.

vazorg [7]

Making a drawing of the system, we will have two forces which are tension and the weight of the object. Balancing the forces present, we do as follows:

T = W
W = 30 N

Therefore, weight is equal to 30 N. Hope this answers the question. Have a nice day. Feel free to ask more questions.

A man has a mass of 110kg. What is his weight?

Stells [14]

His weight depends on where he is, because

Weight = (mass) x (gravity in the place where the mass is) .

For example:

-- If this man is on Mars, his weight is (110 kg) x (3.7 m/s²) = 408 Newtons

-- If he is on the Moon, his weight is (110 kg) x (1.6 m/s²) = 176 Newtons

-- If he is on Earth, his weight is (110 kg) x (9.8 m/s²) = 1,078 Newtons

-- If he is in a spacecraft coasting from one to another, his weight is zero.

A hiker walks 20.51 m at 33.16 degrees. What is the Y component of his displacement?

Serhud [2]

Answer:

<em>The y component of his displacement is 11.22 meters</em>

Explanation:

<u>Components of the displacement</u>

The displacement is a vector because it has a magnitude and a direction. Let's suppose a displacement has a magnitude r and a direction θ, measured with respect to the positive x-direction. The horizontal component of the displacement is calculated by:

$x=r\cos\theta$
