More compressed. moving up = apparent weight (i.e., your norma force) is greater. this means you’ll weighr more and push those springs down even more than you would at rest.
Answer:
The expected dynamic error is 0.019
The phase shift is -23.10°C

Answer:
Explanation:
The equation for this, since we are talking about weight on an elevator, is Newton's 2nd Law adjusted to fit our needs:
where the Normal Force needed to lift that elevator car is the tension. So the equation then becomes
T = ma + w where T is the tension in the cable to lift the elevator, m is the mass of the elevator (which we have to solve for), a is the acceleration of the elevator (positive since it's going up), and w is the weight of the elevator (which we have as 5500 N). Solving first for mass:
w = mg and
5500 =- m(10) so
m = 550 kg. Now we have what we need to solve for the tension:
T = 550(4.0) + 5500 and
T = 2200 + 5500 so
T = 7700 N
Answer:
c
Explanation:
efficiency is measured in % hence 0.02% is smaller than 20%
Answer:
A naturally radioactive element of the actinide metals series. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, Plutonium dioxide is formed when plutonium or its compounds (except the phosphates) are ignited in air, and Plutonium oxide fired at temperatures 600 C is difficult to rapidly.
