To drive your car from Auburn to Atlanta (173.8 km) takes a significant amount of work. Assuming the force of friction between t
Daniel [21]

Answer:

1788.402 MJ

Explanation:

Work done = Force (N) x distance (m)

First we have to convert distance into metres:

173.8 x 1000 = 173,800 m

Then plug these values into the equation above:

173,800 x 10290 = 1788402000 J

The reason it's Joules (the unit for energy) is because work done = energy transferred

Now we have to convert Joules into Mega Joules:

1 J = 1/1000000 MJ

1788402000 J = 1788402000/ 1000000 = 1788.402 MJ

When a beta minus decay occurs in an unstable nucleus, what happens to the atomic number of the nucleus?The atomic number increa
vivado [14]

Answer:

The atomic number increases by 1.

Explanation:

The beta minus decay is a process in which a neutron decays into a proton, emitting an electron and an anti-neutrino:

n \rightarrow p + e + \bar{\nu}

If this process occurs inside an unstable nucleus, we notice that:

- a neutron is converted into a proton, therefore

- the number of neutrons decreases by 1 and the number of protons increases by 1

Keep in mind that the atomic number of a nucleus corresponds to the number of protons it contains: therefore, since this number increases by 1, then the atomic number increases by 1.

At 9:13 A.M., a sports car is traveling 34 miles per hour. Two minutes later, the car is traveling 84 miles per hour. The mean v
WITCHER [35]

Answer:

Acceleration will be 25miles/hour^2                    

Explanation:

We have given that car is traveling with speed 34 miles per hour

So initial speed of the car u = 34 miles per hour

After 2 hour speed will be 84 miles per hour

So final speed V = 84 miles per hour

Time = 2 hour

From first equation of motion we know that v=u+at

So acceleration a=\frac{v-u}{t}=\frac{84-34}{2}=25miles/hour^2
