I think the gravity doesn't affect the mass of an object. Only it's weight can be compared

Gravity has no effect on mass.

But the same mass will WEIGH 1.1 times as much on Neptune if you take it there.

Which of the following is not a reason fluorescent lamps are advantageous over incandescent lamps?A. Fluorescent lamps are more
mr_godi [17]

Answer:

B. Fluorescent lamps operate at a higher temperature than incandescent

Explanation:

Fluorescent lamps have a number of advantages over incandescent lamps which are given in the options given in A, C and D. The option available in B is a drawback, not an advantage. This is because it can give out and radiate more heat as a result of working at a higher temperature. Hence B option is correct.

Explanation:

When pH of the solution is 11.

..(1)

At pH = 11, the concentration of ions is .

When the pH of the solution is 6.

..(2)

At pH = 6, the concentration of ions is .

On dividing (1) by (2).

The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is .

Difference between the ions at both pH:

This means that Hydrogen ions in a solution at pH = 7 has ions fewer than in a solution at a pH = 6

. A helicopter is 8.50 m above the ground and climbing at 2.5 m/s. It drops a package from rest (relative to the helicopter). At
Rudik [331]

Answer:

2.5 m/s

Explanation:

The velocity of the package relative to the ground = the velocity of the package relative to the helicopter + the velocity of the helicopter relative to the ground

v = 0 m/s + 2.5 m/s

v = 2.5 m/s

At the moment it is released, the package is rising at 2.5 m/s.

Steam enters a turbine at 400K and exhausts at 360K. Calculate the maximum efficiency. =%
kozerog [31]

The maximum efficiency is 10%

Explanation:

The maximum efficiency of a machine is given by:

\eta=1-\frac{T_C}{T_H}

where

T_H is the temperature of the hot reservoir

T_C is the temperature of the cold reservoir

For the machine in this problem, we have:

T_H=400K is the temperature of the hot reservoir

T_C=360K is the temperature of the cold reservoir

substituting, we find the max efficiency:

\eta=1-\frac{360}{400}=0.1

So, the efficiency is 0.10 (10%).
