A strong, weightless rope has a 0.15 kg mass hanging from the middle of it. What tension force will make the rope horizontal, corresponding to θ=0°?

Well, let's not beat around the bush here. If the rope is weightless, then it surely is on some serious diet, because it has managed to lose all that weight. Bravo, rope! Now, as for the tension force required to make the rope horizontal, it's like trying to keep a straight face while watching a funny movie - it might seem impossible, but it's all about balance.

In this case, since the rope is horizontal, we can visualize the tension forces acting on the hanging mass as equal and opposite forces on each side. So, if we call the tension force T, then we'll have T to the left and T to the right, ka-pow! This will create equilibrium for our hanging mass.

Now, since the horizontal rope is as straight as a joker's poker face, we know that the angles at each end of the rope will be the same. In other words, the angles from each end of the rope to the vertical will both be 90° - θ. And since we're told that θ is 0°, we can safely assume that both angles are a perfect 90°.

With that, we can conclude that the forces acting vertically on the hanging mass are its weight and the vertical components of the tension forces. However, since our hanging mass is weightless (thanks to that amazing diet), the only force acting on it is the vertical component of the tension force.

Using some good old trigonometry, we can find that the vertical component of the tension force is given by T sin(90° - θ) = T sin 90° = T.

So, in conclusion, the tension force required to make the rope horizontal, corresponding to θ=0°, is simply T. You got this, rope!

To determine the tension force that will make the rope horizontal, we can use the concept of equilibrium. In this case, since the rope is horizontal (θ = 0°), the forces acting on the mass are balanced.

We can break down the forces acting on the mass into horizontal and vertical components.

The weight of the mass will have a vertical component acting downwards, and the tension force will have a horizontal component acting upwards. Since the mass is hanging in the middle of the rope, the horizontal tension force will be balanced by the weight's vertical component.

The weight of an object can be calculated using the formula:
Weight = mass × acceleration due to gravity

Given that the mass is 0.15 kg and the acceleration due to gravity is approximately 9.8 m/s², we can calculate the weight of the object:
Weight = 0.15 kg × 9.8 m/s²

Next, we need to determine the horizontal component of the weight. Since the angle θ is 0°, the horizontal component is equal to the weight.

Finally, the tension force required to make the rope horizontal is equal to the horizontal component of the weight:
Tension Force = horizontal component of weight = Weight

Therefore, the tension force required to make the rope horizontal is equal to the weight of the hanging mass, which is 0.15 kg × 9.8 m/s².

To find the tension force required to make the rope horizontal, we need to consider the forces acting on the mass hanging from the rope.

First, let's define the forces involved:

1. Tension force (T): The force applied by the rope to support the hanging mass.
2. Weight (W): The force due to gravity acting on the mass. It can be calculated using the equation W = m * g, where m is the mass and g is the acceleration due to gravity (approximately 9.8 m/s²).

In this scenario, since the rope is weightless, it doesn't contribute to the forces acting on the mass. Hence, the tension force (T) must balance the weight (W) to keep the rope in equilibrium.

Since we want the rope to be horizontal (θ = 0°), we know that the force imparted by the rope will be equal to the weight of the mass. Therefore, the tension force (T) should be equal to the weight (W).

Let's calculate the tension force:

Given:
Mass (m) = 0.15 kg

Calculating the weight:
W = m * g
W = 0.15 kg * 9.8 m/s²
W = 1.47 N

Therefore, the tension force required to make the rope horizontal is approximately 1.47 N.
