Help<br><br><br> What are energy and work
mylen [45]

Answer:

<em>In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.</em>

A person is guilty of second degree misdemeanor if he or she makes a false statement or commits forgery about their motor vehicle’s insurance.

 

You would be required to have bodily injury liability insurance in Florida if you are involved in a crash where your vehicle has caused damage to the property of others.

 

Though, a person is not required to have a Bodily Injury Liability<span> (BI) to legally drive an automobile in the state of Florida. Nevertheless, it would be possible if you are driving under the influence since you are driving while impaired, driving while intoxicated or drunk driving.</span>

An island reports that in the year 2000 there were 240 babies born. That same year, 100 individuals died.
lyudmila [28]

Answer:

+ 140

Explanation:

You can show the natural growth rate by subtracting the death rate from the birth rate during one year and converting this into a percentage.

Here it would be:

240 - 100 = + 140

// if you want to convert it to percentage, you need to know the size of the population

it would be

140 / (population size) * 100 %

A baseball of mass 300-g is hit at a velocity of 40 m/s. If the ball is caught by the third baseman and the ball penetrates 2.0
OlgaM077 [116]

The force is -12,000 N

Explanation:

First of all, we calculate the acceleration of the ball, by using the following suvat equation:

v^2-u^2=2as

where:

v = 0 is the final velocity of the baseball (it comes to rest)

u = 40 m/s is the initial velocity

a is the acceleration

s = 2.0 cm = 0.02 m is the displacement of the ball

Solving for a,

a=\frac{v^2-u^2}{2s}=\frac{0-40^2}{2(0.02)}=-40,000 m/s^2

Now we can calculate the average force exerted on the ball, by using Newton's second law:

F=ma

where

m = 300 g = 0.3 kg is the mass of the ball

a=-40,000 m/s^2 is the acceleration

Substituting,

F=(0.3)(-40,000)=-12,000 N

where the negative sign indicates that the direction of the force is opposite to the direction of motion of the ball.
