32f. That's because the force is directly proportional to the product of the masses and inversely proportional to the square of the distance. So you get 2•(1/1/4)^2=2•16=32
They should be bigger as if it is hot the tracks will expand as it is made of metal and then there is more room for it to expand or contract
Answer:
Explanation:
Given that,
Displacement in North = 11 km
Displacement in East = 11 km
We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :
Hence, the approximate displacement of the hiker from the camp is .
Answer:
Equal Densities
Explanation:
if the density of the object was greater than that of the liquid, it would sink to the bottom. if the density od the object was lesser than the liquid, it would float :)
Answer:
22,800 years
Explanation:
Half life equation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is time,
and T is the half life.
0.0625 = (½)^(t / 5700)
log 0.0625 = (t / 5700) log 0.5
4 = t / 5700
t = 22,800
It takes 22,800 years.
