A block of wood is floating in a pool of water. How does the volume of water displaced by the block compare to the volume of the

pogonyaev

Answer:

The volume of water displaced the same as the volume of the block.

Explanation:

With respect to the principle of floatation, when an object floats in a fluid; its weight is the same as the volume of the fluid displaced.

The volume of the block relates to is dimension and size which can be compared with the volume of the fluid displaced. When the block is floats in water, it would displace a reasonable volume of water. Thus, it would be expected that the volume of water displaced by the block is equal to the volume of the block.

For lunch you and your friends decide to stop at the nearest deli and have a sandwich made fresh for you with 0.300 kg of Italia

Marina CMI [18]

Answer:

Part a)

A = 0.0581 m

Part b)

T = 0.37 s

Explanation:

Slice is dropped on the plate from height 0.250 m

so the speed of the slice while it hit the plate is given as

$v = \sqrt{2gh}$

here we know that

$v = \sqrt{2(9.81)(0.250)}$

$v = 2.21 m/s$

now from momentum conservation

$mv = (m + M)v_f$

$m = 0.300 kg$

$M = 0.400 kg$

from the above equation we have

$0.300 (2.21) = (0.300 + 0.400) v_f$

$v_f = 0.95 m/s$

Now the initial mean position while it will not hit the plate is given as

$0.400 (9.81) = 200 x_1$

$x_1 = 0.01962 m$

now when slice is placed on the plate then the new mean position will be given as

$(0.300 + 0.400)9.81 = 200 x_2$

$x_2 = 0.0343 m$

now we know that speed of SHM is given as

$v = \omega\sqrt{A^2 - x^2}$

here we have

$\omega = \sqrt{\frac{k}{m + M}}$

$\omega = \sqrt{\frac{200}{0.300 + 0.400}}$

$\omega = 16.9 rad/s$

$a = x_2 - x_1 = 0.0343 - 0.01962 = 0.0147 m$

now from above formula

$0.95 = 16.9\sqrt{A^2 - 0.0147^2}$

$A = 0.0581 m$

Part b)

Time period of scale is given as

$T = \frac{2\pi}{\omega}$

$T = \frac{2\pi}{16.9}$

$T = 0.37 s$

What kind of effects should a drug have for it to be called psychoactive?

Molodets [167]

Psychoactive drugs operate by temporarily affecting a person's neurochemistry, which in turn causes changes in a person's mood, cognition, perception and behavior. There are many ways in which psychoactive drugs can affect the brain.
