Can you conclude that a = b if a and b are two sets with the same power set?

The sets A and sets B contains items called elements

It is true that the set A is equal to set B

<h3>How to determine the true statement?</h3>

The sets are given as:

Set A and set B

Since the sets have the same power set, then we have:

P(A) = P(B)

The above means that:

For every element X in A, then the element is also in B

And

For every element Y not in A, then the element is also not in B

So, we can conclude that:

All subsets of the set A are subsets of the set B and vice versa

Hence, the set A is equal to set B

The magnitude of an impulse produced by a 300 g mass rubber ball, striking a wall horizontally at a velocity of 40 m/s, that reb
8090 [49]

Option a. The total force that is calculated is given as 24 n/s

<h3>How to solve for the magnitude</h3>

300 g = 0.3kg

Force = change in momentum / time

We have to find the mass x velocity

0.3 x 40 = 12kg m / s

This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.

Force 1 x 12

= 12 N

The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.

The total force that is exerted would be calculated as 12N + 12N = 24 N/S

A student is bouncing on a trampoline. At her highest point, her feet are 95 cm above the trampoline. When she lands, the trampo
rosijanka [135]

The time she spent in contact with the trampoline is 0.1619 seconds.

The objective of this question is to determine for how long she is in contact with the trampoline?

The conservational force is exerted on the trampoline is equivalent to the sum of the potential energy at the highest point and the elastic energy at the lowest point.

∴

From the given information;

\mathbf{mg \dfrac{(95 +25)}{100} = \dfrac{1}{2}k ( \dfrac{25}{100})^2}

\mathbf{m\times g\times 1.2 = k(0.03125)}

\mathbf{m\times 9.8 \times 1.2 = k(0.03125)}

\mathbf{\dfrac{m}{k} = \dfrac{(0.03125)}{9.8 \times 1.2}}

\mathbf{\dfrac{m}{k} = 0.002657}

Using the Simple Harmonic Motion to determine the time at which she is in contact with the trampoline, we have;

\mathbf{t= \dfrac{T}{2}}

\mathbf{t= \dfrac{2 \pi}{2} \sqrt{\dfrac{m}{k}}}

where;

  • \mathbf{\dfrac{m}{k} = 0.002657}

\mathbf{t= \dfrac{2 \pi}{2} \times \sqrt{0.002657}}}

\mathbf{t=0.1619\ sec}}
