Step-by-step explanation:
1. Figure out what goes into both 56 and 24, in this case its 8.
2. 8 times 7 is 56, 8 times 3 is 24

Answer:
17/50
Step-by-step explanation:
P(red or purple) = number of red or purple / total
There are 7 red rings and 10 purple rings
= (7+10) / 50
= 17/50
Answer:
a) Drag force = 5.67 N
b) Fraction of (drag force/weight) = 0.00964 = 0.964% (just less than 1%)
Step-by-step explanation:
Drag force is given by the expression
Drag force = CρAv²/2
C = Drag coefficient of air for an average human moving through air = 1.0
ρ = density of air = 1.2 kg/m³
A = Cross sectional Area of runner facing the air = 0.72 m²
v = velocity of the runner = (5km/23min) = (5000/23×60) = 3.623 m/s
Drag force = 1(1.2)(0.72)(3.623²)/2
Drag force = 5.67 N
b) Runner's weight = mg = 60×9.8 = 588 N
Fraction of (drag force/weight) = (5.67/588) = 0.00964 = 0.964% (just less than 1%)
Answer:
The answer is 2000 g
Step-by-step explanation:
We use the following equivalence:
1 kg-------1000g
2kg----- X = (2kgx1000g)/1kg= 2000g
