Answer:

As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction.

Answer:

Sliding friction is the force resisting the motion when a body slides on a surface. The force of friction depends on the area of contact between the two surfaces. As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction.

A circuit has resistors R 1 = 468 Ω and R 2 = 125 Ω R1=468 Ω and R2=125 Ω , and two batteries V 1 = 12.0 V and V 2 = 3.00 V V1=1

Answer:

0.0192A

Explanation:

Since, the reading of the galvanometer is 0 A, the voltage across the resistance R will be:

Step 1

VR = V2

VR = 3.00v

Step 2

Calculating the current through the resistance R as below,

IR = V1 - V2 /R1

IR = 12 - 3 /468

IR =0.0192A

What is the passengers velocity on the vertical drop of the tower of terror at Disney world if the distance for the drop is 50m,

andrey2020 [161]

Assuming constant acceleration due to gravity of $a=9.8\,\dfrac{\mathrm m}{\mathrm s^2}$ , and assuming the passengers start at rest, so that $v_0=0\,\dfrac{\mathrm m}{\mathrm s}$ , we have

$v=v_0+at\implies v=\left(9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)(5.5\,\mathrm s)=53.9\,\dfrac{\mathrm m}{\mathrm s}$

or 54 m/s if taking significant digits into account.

Which of the following does not affect the rate of solubility

lions [1.4K]

Answer:

Weight

Explanation:

Weight does not have any effect on solutbility.

For gases their solubility relies a lot on pressure exerted. At higher presure, gases dissolves more readily than ever. The relationship between solubility and pressure is a direct one.

Higher surface area facilitates the rate of a reaction and in essence, helps to dissolve more solute. Surface area exposes a solute to the action of more solvent which would aid solutbility.

Temperature has a high effect on solubility. An increase in temperature would make more solute dissolve in it.
