Answer:

1.8m/s^2

Explanation:

Since the two ropes are going up, their combined force is 105+115=220N. With a gravitational force of 186N, the force of the two ropes pulling up the will be 220-186=34N.

Now we need the mass of the bucket itself in order to find the acceleration of the bucket (remember that F=ma and m is needed to find a). Since gravitational acceleration is 9.8m/s^2 and F=186N, 186/9.8=18.97959184 kg for the mass of the bucket.

Now that we have the mass of the bucket, we can find the acceleration of the bucket. Since F=34N from earlier, 34N/18.97959184kg=1.791397849m/s^2=1.8m/s^2 is the acceleration of the bucket.

Therefore, 1.8m/s^2 is the correct answer.

Lemur [1.5K]

Answer:

The film in a camera be is placed at a distance of 3.67 cm.

Explanation:

Given that,

Focal length of the lens, f = +35 mm = +3.5 cm

Object distance of the flower, u = -75 cm

Using lens formula to find the distance from the lens must the film in a camera be. Using lens formula as :

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{v}=\dfrac{1}{f}+\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{(3.5)}+\dfrac{1}{(-75)}\\\\v=3.67\ cm

So, the film in a camera be is placed at a distance of 3.67 cm.
