Apainter uses a rope to raise a 3.55 kg bucket at a constant speed. how much force does the rope exert on the bucket?

The rope exerts 34.79 N force on the bucket.

Explanation:

Given:

Mass of the bucket,

Acceleration due to gravity,

Speed of the bucket is constant.

Since the speed of the bucket is not changing, there will be no acceleration produced and thus net acceleration of the bucket is 0 m/s².

Now, the forces acting on the bucket are:

1. Upward tension force by the rope, .

2. Downward weight of the bucket, .

As the acceleration of the bucket is zero, therefore, upward force is equal to downward force.

So,

Hence, the tension force on the bucket by the rope is 34.79 N.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
