675g/cm³ is the density of the liquid

Here we have given that

density of wood be ρ.

the volume of the block be V          

The volume of the block =1/4 v

The volume of the immersed block (v) =V-1/4V=3/4V

We know the weight of the block = the weight of the water displaced by the submerged part of the block.

i.e. V x ρ x g    

= 3/4 x900g/cm³                            

= 675g/cm³

Density is a measure of mass divided by the volume of an object. Defined as mass per unit volume. here from the above equation we have substituted the given value and  we got the answer as 675g/cm³

What are the similarities of life science and applied science?
Jet001 [13]

Answer~

Both life science and physical science helps to understand the natural habitat of the earth. Life science deals with the living thing; thus, it is a study of the organic world. On the other hand, physical science deals with nonliving things; thus, it is a study of the inorganic world.

A toy rocket moving vertically upward passes by a 2.0-m-high window whose sill is 8.0 m above the ground. The rocket takes 0.15
sveta [45]

Answer:

v_i = 18.86 m/s

Explanation:

As we know that the speed of the rocket is v1 and v2 at the bottom and top of the window

then we will have

d = (\frac{v_1 + v_2}{2}) t

2 = (\frac{v_1 + v_2}{2})(0.15)

26.67 m/s = v_1 + v_2

also we know that

v_2 - v_1 = (-9.81)(t)

v_2 - v_1 = (-9.81)(0.15) = -1.47

now we have

v_2 = 12.6

also we have

v_1 = 14.1 m/s

now if the sill of the window is at height 8 m from the ground then we have

v_1^2 - v_i^2 = 2 a h

(14.1^2) - v_i^2 = 2(-9.81)(8)

v_i = 18.86 m/s

one layer of earth's atmosphere is called the stratosphere. At one point above earth's surface the stratosphere extends from an
masya89 [10]

According to all the given requirements 

stratosphere x starts at an altitude of 16 km

that means  

<span>16≤x

</span> and,as given ,stratosphere ends at an altitude of 30 km:
which means
<span>x≤30</span> combining both of them we get

<span>16≤x≤30</span> So the range of the stratosphere is from 16 to 30 km.

A metal detector used in airports is actually a large coil of wire carrying a small current. Explain how it detects a gun, even
Alexus [3.1K]

<u>Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within the electromagnetic field will become energised and retransmit an electromagnetic field of their own. The detector’s search coil receives the retransmitted field and alerts the user by producing a target response. metal detectors are capable of discriminating between different target types and can be set to ignore unwanted targets. </u>

1. Search Coil

The detector’s search coil transmits the electromagnetic field into the ground and receives the return electromagnetic field from a target.

2. Transmit Electromagnetic Field (visual representation only - blue)

The transmit electromagnetic field energises targets to enable them to be detected.

3. Target

A target is any metal object that can be detected by a metal detector. In this example, the detected target is treasure, which is a good (accepted) target.
