Answer:
1. 75 N
2. 6.8351 N
3. 700 N
Explanation:
1. Determination of the weight of the bowling ball:
Mass (m) = 7.5 kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?
Weight = mass × acceleration due to gravity
W = m × g
W = 7.5 × 10
W = 75 N
2. Determination of the weight of the object.
Mass (m) = 683.51 g
Weight (W) =?
We'll begin by converting 683.51 g to kg. This can be obtained as follow:
1000 g = 1 Kg
Therefore,
683.51 g = 683.51 g × 1 Kg / 1000 g
683.51 g = 0.68351 Kg
Thus, 683.51 g is equivalent to 0.68351 Kg.
Finally, we shall determine the weight of the object as follow:
Mass (m) = 0.68351 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?
Weight = mass × acceleration due to gravity
W = m × g
W = 0.68351 × 10
W = 6.8351 N
3. Determination of the weight of the KHS student.
Mass (m) = 154 lb
Weight (W) =?
We'll begin by converting 154 lb to Kg. This can be obtained as follow:
2.2 lb = 1 Kg
Therefore,
154 lb = 154 lb × 1 Kg / 2.2 lb
154 lb = 70 kg
Thus, 154 lb is equivalent to 70 kg.
Finally, we shall determine the weight of the KHS student as follow:
Mass (m) = 70 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?
Weight = mass × acceleration due to gravity
W = m × g
W = 70 × 10
W = 700 N
