The volume of a cylindrical tin can with a top and a bottom is to be 16π cubic inches. If a minimum amount of tin is to be used

sergiy2304 [10]

Answer:

h = 4 in

Explanation:

GIVEN DATA:

volume of tin $= 16 \pi$

we know that

volume of cylinder is $v = \pi r^2 h$

so,

$16 \pi = \pi r^2 h$

$16 = r^2 h$

$r = \sqrt{\frac{16}{h}}$

construct formula for surface area

$S = 2\pi r^2 + 2\pi rh$

$S = \frac{2v}{h} + 2 \sqrt{v \pi h}$

minimize the function wrt h

$S' = \frac{2v}{h^2} + \sqrt{\frac{v \pi}{h} = 0$

solving for h we have

$h = [\frac{4 v}{\pi}]^{1/3}$

we kow $v = 16 \pi$ so

h = 4 in

<h3>What is Newton's Second Law of Motion?</h3>

Newton's second law provides a precise explanation of the modifications that a force can make to a body's motion. According to this, a body's momentum changes at a rate that is equal to the force acting on it over time in both magnitude and direction. A body's momentum is equal to the sum of its mass and velocity. Similar to velocity, momentum has both a magnitude and a direction, making it a vector quantity.

acceleration - rate of change of velocity with time, both in terms of speed and direction. A point or object going straight forward is accelerated when it accelerates or decelerates.

There are three types of accelerated motions :

uniform acceleration,
non-uniform acceleration
average acceleration.

express all the units in their most basic form.

kg, newton = kg*m/s², acceleration =m/s²

$\frac{ 30000 kg*m/s^{2} }{ 2000 kg} = 15m/s^{2}$

A block of mass 3.5 kg displaces 1000 cm ^3 of water when fully immersed inside. The upthrust on body will be what.

Arturiano [62]

Given :

Mass of block = 3.5 kg
Weight of Block = 3.5 kgf
Volume of water displaced when body is fully immersed = 1000 cm³

Answer:

For calculating Upthrust on block we will have to first find out Volume of block :

↪Volume of block = Volume of water displaced

↪ Volume of block = 1000 cm³ = 0.001 m³

Now, <u>we will calculate the Upthrust on block</u>:

↪ Upthrust on block = Volume of block * Density of water * g

↪ Upthrust on block = 0.001 * 1000 * g

↪ Upthrust on block = 1 kgf

a light wave travels from air into a medium of refractive index 1.54. If the wavelength of the light in air is 5.4 * 10^-7. calc

kozerog [31]

3.51 × 10^-7m

Explanation:

Refractive index = wavelength of the light in air ÷ wavelength in the medium

wavelength in the medium = wavelength of the light in air ÷ refractive index

= 5.4 * 10^-7 ÷ 1.54

= 3.51 × 10^-7m
