A.
Pressure = force/area
SI units for force = newtons
SI units for area = square meters
So pressure = n/m^2
Answer:
1.The Washington Monument is 555 feet tall.A.If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 1,820.4 mB.A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument?GPE = mghGPE = (0.005 kg)(0 m/s2)(1,820.4 m)GPE = 0 JC.What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument?KE = 1/2mv2KE = (0.5)(0.005 kg)(0 m/s)2KE = 0 JD.If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground?The GPE will decrease because the height is decreasing.E.If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground
Explanation:
The least value varies depends on ammeter range. In the given question, ammeter range is not mentioned. So, the least value of an ammeter is 0.1 or 0.5 (depends on ammeter range).
<u>Explanation:</u>
The least value of an ammeter is the measure of the smallest number which can be observed in ammeter. So the least value will be varying depending upon its range. If we consider the range of ammeter is 30 A and the scale readings are 10 numbers, then the least value will be 30/10 = 3 A per scale.
So the least value is determined as
So among the given options 0.1 is most suitable for an ammeter with range of 3 A with 30 divisions.
