Answer:
Distance
Speed = ----------------
Time
Distance/Displacement
1.5m/s = ------------------------------------------
10s
Distance
1.5m/s × 10 = --------------------- × 10
10s
(Get rid of the fraction by multiplying it by the denominator in this case 10)
15m = Distance
Distance and Displacement are almost the same thing regarding this question. But watch out when you doing other questions and when you have initial velocity and initial time.
Displacement is 15m.
The density of an object is given by:
D = M/V
D = density, M = mass, V = volume
The volume of the cube V is given by:
V = s³
where s = side length
Make a substitution:
D = M/s³
Given values:
M = 20kg, s = 20×10⁻²m
Plug in and solve for D:
D = 20/(20×10⁻²)³
D = 2500kg/m³
Answer:
ΔL = 5.09x10^-5 m
Explanation:
data provided by the exercise:
m = 56 kg
L = 35 cm = 0.35 m
r = 1.5 cm = 0.015 m
Y = 1.6x10^10 N/m^2
F = 3 m*g
A = pi*r^2
The Young´s modulus is equal to:
Y = (F/A)/(ΔL/L) = (F*L)/(A*ΔL)
Clearing ΔL, we have:
ΔL = (F*L)/(A*Y) = (3*56*9.8*0.35)/(pi*(0.015^2)*1.6x10^10) = 5.09x10^-5 m
Acceleration due to gravity on that planet is half than that of om earth ~
that is ~
And it's weight is equal to ~
now, As we know ~
here ,
- g = Acceleration due to gravity on that planet = 4.9 m/s²

______________________________
1. temperature
2. increasing heat
3. its temperature begins rising from -20 C
4. it stops rising and stays steady at 0 C; the ice is using the
added heat to change state, melt, and turn to liquid
5. between 0 C and 100 C
6. it stops rising and stays steady at 100 C; it's being absorbed
by the water, and the water is using it to change state, evaporate,
and turn to gas
7. the heat is making the molecules move around easier
