Answer with Explanation:

Metals Can be described as Shiny While nonmetals are Dull.This is Physical properties of metal.

The Common name of this Physical Property is :

⇒ Luster

Luster: Metals allows to reflect light from its surface when light falls on it and it can be made lustrous that is Polished .For e.g., gold, and silver .

Option C:→ Luster

A body is at equilibrium under the action of three forces. One force is 10N acting due east and one is 5N in the direction 60° n
olchik [2.2K]

Answer:

If the body is in equilibrium the two forces add up and the third is the opposite of the resultant.

F(1x)=F(1)=10 N

F(2x)=F(2)cos60=5•0.5=2.5 N

F(2y) =F(2)sin60 = 5•0.866= 4.33 N

F(3x) =- F(x)=- (10+2.5 )= -12.5 N

F(3y) =- F(2y)= - 4.33 N

F(3) = sqrt{ F(3x)²+F(3y)²} =13.23 N

tan φ = F(3y)/F(3x) =4.33/12.5=0.364

φ = 19.1⁰ (south-west)

A person is standing on a spring bathroom scale on the floor of an elevator which is moving up and slowing down at the rate of 3
aleksklad [387]

Answer:

F_N=1194.24\ N

Explanation:

Given that,

The elevator is moving up and slowing down at the rate of, a=3\ m/s^2

The acceleration due to gravity, g=9.8\ m/s^2

Mass of the person, m = 93.3 kg

To find,

The reading of the scale.

Solution,

As the elevator is moving down with some acceleration. The net force acting on it is given by :

F_N=ma+mg

F_N=m(a+g)

F_N=93.3(3+9.8)

F_N=1194.24\ N

So, the scale will read 1194.24 N.
