Answer:
The SI unit for length is meters(m), for mass is kilograms(kg), for volume is cubic meter(m^3), for density kilogram per cubic meter(kg/m^3), for time is seconds(s), and for temperature is kelvins(K).

Answer:
7,272.7m
Explanation:
Our knowns:
a = 5.2m/s^2
t = 32.8s
= 0 m/s
Our Unknowns:
Distance (x): ?
We can use displacement formula:
ΔX = t + 
a 
Plug in knowns:
X = 0 + 1/2 ((5.2)(32.8))^2
Answer:
ΔX = 7272.7m
(I beleive this should be right) let me know if it helped!
Answer:
468750 J
Explanation:
Kinetic energy = (1/2) (mass)(velocity)^2
Answer:
25g
Explanation:
Given parameters:
Half life of X = 5days
Mass of sample of radioactive elements = 100g
The half-life of a radioactive material is the time it takes for a sample to decay by half. At the half-life, an original sample would have yielded equal daughter to parent ratio.
At time (days) Mass of sample
0 100g
5 50g
10 25g
Every 5 days, the sample will split into half.
Therefore, 25g will remain after 10days.
F = 130 revs/min = 130/60 revs/s = 13/6 revs/s
t = 31s
wi = 2πf = 2π × 13/6 = 13π/3 rads/s
wf = 0 rads/s = wi + at
a = -wi/t = -13π/3 × 1/31 = -13π/93 rads/s²
wf² - wi² = 2a∅
-169π²/9 rads²/s² = 2 × -13π/93 rads/s² × ∅
∅ = 1209π/18 rads
n = ∅/2π = (1209π/18)/(2π) = 1209/36 ≈ 33.5833 revolutions.
