We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
<h3>How we can calculate the thickness using screw gauge?</h3>
We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.
So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

Answer:
D. 24 m
Explanation:
Running up - velocity + 30 m/min
Escalator 's moving down velocity - 24 m/min
Sum velocity (30 - 24) = 6 m/min
6 m/min * 4 min = 24 m
Explanation:
We need convert the velocities first to m/s and we get the following:
v2 = 21 km/hr = 5.8 m/s
v1 = 11 km/hr = 3.1 m/s
We need to find the mass of the car also for later use do using the work-energy theorem:
6.0x10^3 J = (0.5) m [(5.8)^2 - (3.1)^2]
or
m = 499.4 kg
Now we determine work needed delta W to change its velocity from 21 km/hr to 33 km/hr
v2 = 33 km/hr = 9.2 m/s
v1 = 21 km/hr = 5.8 m/s
delta W = (0.5)(499.4)[(9.2)^2 - (5.8)^2]
= 1.3 x 10^4 J
Since you provide no options, here are some role of the foresters :
- they develop sustainable forest practice
- They asses timber Quality
- They make sure that all harvesting activities followed the law's regulation
- They plan and supervise forestry project
