Answer:
350N, 800 N
Step-by-step explanation:
for question no 6
mass (m) = 70 kg
acceleration (a) = 5 m/s²
Force (F) = m * a = 70 * 5 = 350 N
for question no 7
mass (m) = 80 kg
acceleration (a) = 10 m/s²
Force (F) = m * a = 80 * 10 = 800 N
Hope it will help :)❤

Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth
Answer:
6m
Step-by-step explanation:
Answer: Four times the amount of flour for the raisin bread plus 2.5 cups equals 12.5 cups total. The equation is 4x + 2.5 = 12.5. First, I subtract 2.5 from both sides, and then I divide both sides by 4. Each loaf contains 2.5 cups of flour.
