Mr. Hix leaves Warrenton at 3:00pm. He has to be in another city 186km away at 6:00pm. Can he arrive at the second city on time? Explain. A train travd 350km in 2.5 hours. What is the average speed of the train? Show your work if you can.

1.  v=s/t=186/3=62. Yes because 62x3=186 and that is exactly how far he needs to go.

2. 90 kilometers an hour

Explanation:

I am in Mr. hix's class oh my god this is so funny.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
