Answer:

The tension T in each of the cables, T = 98 N

Explanation:

Given,

The mass of the loudspeaker, m = 20.0 Kg

The suspended distance of the loudspeaker, d = 2.20 m

The length of each cable, l = 2.9 m

The tension experienced by the cable is given by the formula,

T = mg + ma newton

Where,

g - acceleration due to gravity

a-acceleration produced by the stretched cable

Since the stretched cable and loudspeaker is not moving, then the tension force acting on the cable is equal to the force of gravity.

T = mg newton

Substituting the values in the above equation

T = 20

= 20.0 Kg x 9.8 m/s²

= 196 N

This force is equally supported by the two cables, then the tension in each cable is

T = 196 N / 2

= 98 N

Hence, the tension T in each of the cables, T = 98 N

A 300 cm rope under a tension of 120 N is set into oscillation. The mass density of the rope is 120 g/cm. What is the frequency

Vikki [24]

Answer:

Explanation:

f = $\sqrt{T/(m/L)} / 2L$

T = 120 N

L = 3.00 m

(m/L) = 120 g/cm(100 cm/m / 1000 g/kg) = 12 kg/m

(wow that's massive for a "rope")

f = $\sqrt{120/12} /(2(3))$ )

f = $\sqrt{10\\}$ /6 = 0.527 Hz

This is a completely silly exercise unless this "rope" is in space somewhere as the weight of the rope (353 N on earth) far exceeds the tension applied.

A much more reasonable linear density would be 120 g/m resulting in a frequency of √1000/6 = 5.27 Hz on a rope that weighs only 3.5 N

Humans first traveled to the Moon in a spacecraft in 1969. What happened as the spacecraft traveled farther from Earth?

horsena [70]

Answer:

The answer is C)The force of gravity from Earth acting on the spacecraft decreased because the distance from Earth increased.

Explanation:

Gravity, a force, is dependent on the mass of the object exerting the gravity and the distance of an outside object from that object. The larger the object, the more gravity it will exert on an outside object. This force decreases as you move away from the object, but it will always still exist and never be equal to 0.
