Talking about a quantity of inertia is exactly the same as talking about a quantity of mass. So, if the boxes are anywhere near the same size, then the box of books has more inertia than the box of cotton balls, because books have more mass than an identical volume of cotton.

A box of books has more inertia than a box of cotton balls.

Explanation:

Inertia is related to the mass of the object. Inertia is usually defined as the resistance offered by the object in response to the movement or the velocity of the object.

The object will higher mass will have higher inertia as it should offer more resistance to remain in inertia and the object with lesser mas can offer smaller resistance comparatively. So here, the box of books has more inertia than a box of cotton balls.

A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of th

Marina CMI [18]

Answer:

The radius of the curve is 9,183.67 m.

Explanation:

Given;

velocity of the jet plane, v = 600 m/s

acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²

The radius of the curve is calculated from centripetal acceleration formula as given below;

$a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m$

Therefore, the radius of the curve is 9,183.67 m.

Find the ratio of the lengths of the two mathematical pendulums, if the ratio of periods is 1.5

juin [17]

Answer:

The ratio of lengths of the two mathematical pendulums is 9:4.

Explanation:

It is given that,

The ratio of periods of two pendulums is 1.5

Let the lengths be L₁ and L₂.

The time period of a simple pendulum is given by :

$T=2\pi \sqrt{\dfrac{l}{g}}$

$T^2=4\pi^2\dfrac{l}{g}\\\\l=\dfrac{T^2g}{4\pi^2}$

Where

l is length of the pendulum

$l\propto T^2$

$\dfrac{l_1}{l_2}=(\dfrac{T_1}{T_2})^2$ ....(1)

ATQ,

$\dfrac{T_1}{T_2}=1.5$

Put in equation (1)

$\dfrac{l_1}{l_2}=(1.5)^2\\\\=\dfrac{9}{4}$

So, the ratio of lengths of the two mathematical pendulums is 9:4.

Chemical bonds that are formed when one atom with a partial positive charge (created from unequal sharing of electrons) is elect

Tamiku [17]

Answer:

Polar covalent bond

Explanation:

When two atoms of unequal electro- negativity comes together to form bonds , there is unequal sharing of electrons between them , one of them acquaring partial positive and partial negative charge . Then they make bond due to mutual attraction.

Bond formation in HCl in gaseous state is an example .

The mass of a cm3(cube) stone is 180.

ss7ja [257]

Density = (mass) / (volume), no matter how large or small the sample is.

We can't calculate the density, because you left out the number for the volume.
Also, you didn't tell us the unit for the mass of 180.

a). If the mass is 180 grams, then the density is

(180 gm) / (volume) .

b). No matter how many pieces you crush it into, and
no matter how large or small a piece is, its density is
the same. (I just wish we knew what the density really is.)

c). A piece may have 80 grams of mass. It doesn't "weigh" 80 grams.

Since the density of the whole rock is (180 gm) / (volume),
the density of any piece of it is (180 gm) / (volume).

Multiply each side by (volume): (Density) x (volume) = 180 gm

Divide each side by (density): Volume = (180 gm) / (density)

We can't calculate the volume of an 80-gm piece, because
we don't know the density. (That's because you left the volume
out of the question.)
