Lucy lightfoot stands with one foot on one bathroom scale and her other foot on a second bathroom scale. each scale reads 380 n
1 answer:
Answer: 760 N
Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.
When Lucy stands on the weighing scale, net force due to gravity is
Hence, weight of Lucy is 760 N

Explanation:
Given
mass of rock
diameter of circle
radius
At highest Point
At highest Point N=0 because mass is just balanced by centripetal Force
thus
The cost of excavating a space of 84 ft long, 42 ft wide, and 9 ft deep is $45864
Information about the problem:
- Space long= 84 ft
- Space wide= 42 ft
- Space deep= 9 ft
- Cost by yard3 = $39/yd3
- Total cost= ?
To solve this problem, we have to state the equation using the information of the problem:
Calculating the volume of the total space:
space volume = space long * space wide * space deep
space volume = 84 ft * 42 ft * 9 ft
space volume = 31752 ft3
By converting the volume from ft3 to yd3, we have:
31752 ft3 * (0,037037 yd3 / 1 ft3) = 1176 yd3
Calculating the cost of excavating the volume space:
Total cost = space volume * cost by yard3
Total cost = 1176 yd3 * $39/yd3
Total cost = $45864
<h3>What is volume?</h3>It is the space occupied by a body, it is calculated by multiplying its dimensions, for example: length, height and width.
