- Displacement = 10 m
- Time = 5 s
- We know,
- Therefore, the car's velocity
<h3>Answer:</h3>
The car's velocity is 2 m/s.
Hope you could get an idea from here.
Doubt clarification - use comment section.
ind the velocity my using the conservation of energy mgh=1/2mv^2. At the bottom, the mass is turning in a circle with tension pointing up towards the center of the circle and weight pointing down. Use the centripetal force requirement mv^2/r=T-W and solve for T. Hope this helps.
Its (a) and(a)for the other ? and the last one is (d)
That depends on what type of pressure you are attempting to measure, to measure Atmospheric pressure, you would use a Barometer. To measure things like tires, you could use a Tire Pressure Gauge. For Industrial processes and boilers, you would use a Manometer. For pressure vessels, you would use a Bordon Gauge. <span />
