Answer:

words that have the same sound but different spellings and meaning

Explanation:

Homophones are generally words that sound the same but have different spellings and even meaning.

For example the words new and knew are homophones.

They have the same sound when pronouncing but their meaning is different.

Also, the words bawl and ball are homophones.

We see that both words have very similar pronunciation but their meanings are completely different.

According to Galileo, this quantity is not needed to keep a body in motion under ideal conditions.
Sergio [31]
This condition is called Galileo's Law of Inertia which states that all bodies accelerate at the smart rate , no matter what are their masses or size. Inertia is that tendency of matter to resist changes in its velocity.  <span>Isaac Newton's first law of motion captures the concept of inertia. </span>

In principle, when you fire a rifle, the recoil should push you backward. How big a push will it give? Let’s find out by doing a
mixer [17]

Answer:

0.07142 m/s in the opposite direction of the bullet

Explanation:

m_1 = Mass of rifle = 70 kg

m_2 = Mass of bullet = 0.01 kg

v_1 = Velocity of rifle

v_2 = Velocity of bullet = 500 m/s

As the momentum of the system is conserved

m_1v_1+m_2v_2=0\\\Rightarrow v_1=-\frac{m_2v_2}{m_1}\\\Rightarrow v_1=-\frac{0.01\times 500}{70}\\\Rightarrow v_1=-0.07142\ m/s

The recoil velocity of the rifle is -0.07142 m/s

The negative sign shows the opposite direction of the rifle.

a. A rectangular pen is built with one side against a barn. 1900 m of fencing are used for the other three sides of the pen. Wha
Natalka [10]

Answer:

475 m , 950 m

Explanation:

Let l be the length of the side perpendicular to the barn.

1900-2l = length of the side parallel to the barn

Area A= l( 1900-2l)

A= 1900l-2l^2

now, the maximum value of l ( the equation being quadratic)

l_max= -b/2a

a= 2

b=1900

l_max= -1900/4= 475 m

then 1900-2l= 1900-2×(475) = 950 m

So, the dimensions that maximize area are

950 and 475

Now. A_max = -2( l_max)^2+1900×l_max

A_max=  -2(475)^2+1900×475

A_max= 451250 m^2

or, 475×950 = 451250 m^2
