Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
Answer:
If the rod is swapped for a different material such as acetate , electrons are rubbed off the acetate and onto the duster. The acetate rod has lost electrons, giving it a positive charge. The duster has gained electrons, giving it a negative charge.

Answer:
no
Explanation:
a constant speed = speed stays the same
accelerating = speed is increasing
This question involves the concepts of general gas equation and pressure.
The force exerted by the gas on one of the walls of the container is "74.08 KN".
First, we will use the general gas equation to find out the pressure of the gas:
where,
P = Pressure of the gas = ?
V = Volume of cube = (side length)³ = (10 cm)³ = (0.1 m)³ = 0.001 m³
n = no. of moles = 3 (since molecules equal to avogadro's number make up 1 mole)
R = general gas constant = 8.314 J/mol.K
T = Absolute Temperature = 24°C + 273 = 297 K
Therefore,
P = 7407.78 KPa
Now, the force on one wall can be given as follows:
where,
A = area of one wall = (side length)² = (0.1 m)² = 0.01 m²
Therefore,
<u>F = 74.08 KN</u>
