Answer:

The total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order is 15.

Explanation:

Given :

Numbers -- 2020 and 2400

The following steps can be used in order to determine the total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order:

Step 1 - According to the given data, there are two numbers 2020 and 2400.

Step 2 - So, the integers having four distinct digits arranged in increasing order are:

2345, 2346, 2347, 2348, 2349, 2356, 2357, 2358, 2359, 2367, 2368, 2369, 2378, 2379, and 2389.

Step 3 - So, the total number of integers between 2020 and 2400 have four distinct digits arranged in increasing order is 15.

Answer:

2440.24 J

Explanation:

Moment of inertia, I1 = 5 kg m^2

frequency, f1 = 3 rps

ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s

Moment of inertia, I2 = 2 kg m^2

Let the new frequency is f2.

ω2 = 2 x π x f2

here no external torque is applied, so the angular momentum remains constant.

I1 x ω1 = I2 x ω2

5 x 6 π = 2 x 2 x π x f2

f2 = 7.5 rps

ω2 = 2 x π x 7.5 = 15 π

Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J

Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J

Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J
