Answer:

B. Iron nails are attracted to the magnet

Explanation:

A <em>qualitative observation</em> is an observation that gives <em>qualitative data </em>-as opposed to quantitative-. This means that the data is non-numerical (or <u>unquantifiable</u>). In other words it could be said that a qualitative observation can be reached when you don't count anything. In chemistry qualitative observations can be made of properties such as color, smell, or whether or not a species is attracted to a magnet.

Murljashka [212]

Answer:

formula

ΔP= PgΔh

Explanation:

Calculation.

ΔP = (1.05 x 10^3kg/m^3)(9.8m/s^2)(6ft equivalent to 1.8288m)

ΔP = 1.05 x 10^3 kg/m^3 x 9.8m/s^2.

x1.8288.

ΔP = 1.88 x 10^4 Pa.

12. The answer would be C. 1.50 s. This is because if you divide 60 by 40, you will get 1.5.

13. For this one I'm not sure, but what I can tell you is that the heavier something is the faster it will sink, the lighter it is, it will float.

For a vertical spring-mass oscillator that is moving up and down, which of the following statements are true? (more than one sta
omeli [17]

Answer:

At the lowest point in the oscillation, the momentum is zero.

At the lowest point in the oscillation, mg < ks_s

Explanation:

Since spring block system is performing to and fro motion along straight line

So here we can say at the lowest position of its path the velocity will become zero.

So we can say that momentum of the spring block system is given as

P = mv

P = 0

Also we know that after reaching the lowest point the block will again go up towards its mean position

So at the lowest point of the spring block system the block will move upwards again

So this will accelerate upwards hence

F_{spring} > mg

Ks > mg
