Answer:
Alice Distance = 100 meters
Peter's Distance = 3 km
Alice Displacement and Peter's displacement are both 100 meters upwards.
Explanation:
To solve this question, we have to first define distance and displacement.
Distance is simply the measurement of the sum of all paths travelled from one point to another while displacement is measurement of the shortest distance from initial point to final point.
Now, Alice and Peter are moving from the same point.
Alice distance travelled is 100 meters.
Also, her displacement will be 100 meters because it is the shortest distance to the summit of the cliff.
Now, for Peter, he decides to take a longer route which is 3 km in distance.
However, the shortest path which is the displacement is still 100 meters.
Thus, Peter's displacement is 100 meters.
The helium atom is found to contain more particles than the hydrogen atom.
<h3>What is a subparticle?</h3>
An atom is composed of particles and these particles are electrons protons and neutrons. The collective name for these particles is the subatomic particles.
Now we know that the helium atom contains more sub atomic particles than the atom of hydrogen. This is because, the helium atom contains two neutrons and two protons as well as two electrons. On the other hand, the hydrogen atom contains one neutron and one proton as well as one electron.
Thus, the helium atom is found to contain more particles than the hydrogen atom.

It gets warmer because the forming ice gives heat up
Answer:
Increasing length increases resistance
increasing cross sectional area reduces the resistance
.
Explanation:
The formula for resistance of an object is

where r is resistance, d is resistivity of the material, l is length of material and a is cross sectional area of the object. This equation shows us that resistance is directly proportional to length and inversely proportional to cross sectional area. Hence, increasing length increases resistance while increasing cross sectional area reduces the resistance.
If these 2 variables are varied to the same extent, the net effect can be zero on the resistance.
