Step-by-step explanation:
A =nr²
=3.14 × (80/2)
=3.14 × 40
= 125.6yd²
1. 14.4 km, 2. 25.2 km, 3. 37.8 km
Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
<span>9/5C + 32 =
= 9/5 * 20 + 32
= 36 + 32
= 68
20 C = 68 F
