Answer : Option C) Roughness of the surface and weight of the object.

Explanation : The factors that affect the forces of friction are roughness of the surface and weight of the object.

Friction is the force which resists the relative motion of solid surfaces, fluid layers, and material elements which are sliding against each other.

Friction depends on the normal force and the roughness of the surface which is in contact. When a body is placed on the ground, the mass of the body which is weight = mass x acceleration due to gravity, comes into play for the normal force from the ground. This clearly shows that friction is affected by weight as it depends on the mass of the object.

It also depends partly on the smoothness of the contacting surfaces, if a greater force being applied to move two surfaces past one another then they are rough, if they were smooth less force would have been applied for moving it.

The heating element of a hair dryer dissipates 1500 w when connected to a 180 v outlet. part a what is its resistance?
Sophie [7]

The resistance of the heating element is 21.61 Ω

Given

The power dissipated = 1500 W

Voltage = 180 V

We know that

Power = Voltage * Current

⇒ Power / Voltage = Current

⇒ 1500 W/180 V = Current

⇒ 8.33 A = Current

In order to calculate the resistance of the heating element. We Have to apply the formula

Power = (Current)^2 * Resistance

⇒ Resistance = Power / (Current)^2

⇒ Resistance = 1500 W/ (8.33) ^2

⇒ Resistance = 21.61 Ω

Hence the resistance of the heating element is 21.61 Ω

Convert 0.02 g/mL to the unit g/L.
Elenna [48]
I don't know but I think that 0.02 g/mL is 20 g/L because you multiply the 0.02 by a 100. That's how you get the Gram liter
