Answer:
32000cm^3
Explanation:
Length L be base length
h be the height
Volume=V
V=L^2h
Surface area if box= L^2+4lh=4800
Solving for h
(4800-l^2/4L)=h
1200L-L^3/4=h
Substitute for h in V =L^2h
v=1200L-L^3/4
Differenting =1200-3*L^2/4=0
L=√(1600)=40
Substitute L=40
In V=1200L-L^3/4
Hence 1200*40-40^4/4=32000cm^3
Answer:
80×5×10=4000J
so therefore, work done on the body is 4000J
Currently, the magnetic south pole lies about ten degrees distant from the geographic north pole, and sits in the Arctic Ocean north of Alaska. The north end on a compass therefore currently points roughly towards Alaska and not exactly towards geographic north.

Answer:
x_total = 600 m
Explanation:
This is an exercise and kinematics, let's find the time it takes to reach the velocity 20 m / s
v = v₀ + a t
as part of rest v₀ = 0
t = v / a
t = 20/2
t = 10 s
let's find the distance traveled in this time
x₁ = vo t + ½ a t2
x₁ = 0 + ½ 2 10²
x₁ = 100 m
The remaining time is
t₂ = 35 - t
t₂ = 35 - 10
t₂ = 25 s
as in this range it has a constant speed
v = x₂ / t₂
x₂ = v t₂
x₂ = 20 25
x₂ = 500 m
the total distance traveled is
x_total = x₁ + x₂
x_total = 100 + 500
x_total = 600 m
