Explanation:

Radicals are atoms that have an unpaired electron. They are very reactive and don’t exist for very long. If they react with a molecule, the products of the reaction will be a different molecule and a different radical. If two radicals react the product is a single molecule.

Ions have either gained or lost electrons to end up with a completed outer shell. They tend to strongly attract ions of opposite charge to make ionic compounds.

•What power does a pump develop to lift 35 L of water per minute

guajiro [1.7K]

Answer:

$p = \frac{w}{t} \\ p = \frac{f \times d}{t} \\ p = \frac{m \times g \times d}{t} \\ p = \frac{35 \times 9.8 \times 110}{60.0} \\ p = 629w$

A firecracker in a coconut blows the coconut into three pieces. Two pieces of equal mass fly off south and west, perpendicular t

Lisa [10]

Explanation:

Let us assume that piece 1 is $m_{1}$ is facing west side. And, piece 2 is $m_{2}$ facing south side.

Let $m_{1} \text{and} m_{2}$ = m and $m_{3}$ = 2m. Hence,

$2mv_{3y} = m(21)$

$v_{3y} = \frac{21}{2}$

= 10.5 m/s

$2mv_{3x} = m(21)$

$v_{3x} = \frac{21}{2}$

= 10.5 m/s

$v_{3} = \sqrt{v^{2}_{3x} + v^{2}_{3y}}$

= $\sqrt{(10.5)^{2} + (10.5)^{2}}$

= 14.84 m/s

or, = 15 m/s

Hence, the speed of the third piece is 15 m/s.

Now, we will find the angle as follows.

$\theta = tan^{-1} (\frac{v_{3y}}{v_{3x}})$

= $tan^{-1}(\frac{10.5}{10.5})$

= $tan^{-1} (45^{o})$

= $45^{o}$

Therefore, the direction of the third piece (degrees north of east) is north of east.

The volume of a gas is reduced from 4 l to 0.5 l while the temperature is held constant. How does the gas pressure change?

shusha [124]

Answer:

The pressure increases by a factor 8

Explanation:

For a gas held at constant temperature, Boyle's law can be applied. It states that the product of the gas pressure and the gas volume is constant, so we can write:

$p_1 V_1 = p_2 V_2$

where

$p_1$ is the initial pressure

$p_2$ is the final pressure

$V_1$ is the initial volume

$V_2$ is the final volume

For the gas in this problem, the volume is reduced from

$V_1 = 4 L$

$V_2 = 0.5 L$

so we can rewrite the equation as

$\frac{p_2}{p_1}=\frac{V_1}{V_2}=\frac{4 L}{0.5 L}=8$

this means that the pressure of the gas will increase by a factor 8.

A train car has a mass of 10,000 kg and is moving at +3.0 m/s. It strikes an identical train car that is at rest. The train cars

shtirl [24]

In order to compute the final velocity of the trains, we may apply the principle of conservation of momentum which is:
initial momentum = final momentum
m₁v₁ = m₂v₂

The final mass of the trains will be:
10,000 + 10,000 = 20,000 kg
Substituting the values into the equation:

10,000 * 3 = 20,000 * v
v = 1.5 m/s

The final velocity of the trains will be 1.5 m/s
