A chair of weight 100 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 4
otez555 [7]

Answer:

The normal force will be "122.8 N".

Explanation:

The given values are:

Weight,

W = 100 N

Force,

F = 40 N

Angle,

θ = 35.0°

As we know,

⇒  N=W+FSin \theta

On substituting the given values, we get

⇒      = 100N+40N \ Sin \theta

⇒      =100N+22.8

⇒      =122.8 \ N

Janice has just measured the density of an object. Which value is possible? (Density: D = )
Sunny_sXe [5.5K]

By definition, the density of an object is given by:

D = \frac{M}{V}

Where,

M: mass of the object

V: volume of the object

Since the mass and volume of an object are numerical values greater than zero, then it follows that:

D> 0

It is important to respect the units of each measure.

For this case we can use the grams for the mass and cubic centimeters for the volume.

Answer:

A possible value for density is given by:

6 \frac{g}{cm^3}

Two large metal parallel plates carry opposite charges of equal magnitude. They are separated by 45.0 mm, and the potentialdiffe
DENIUS [597]

Answer:

a. 8000 N/C or 8000 V/m

b. Incomplete question

Explanation:

a. The electric field, E, is the ratio of the potential difference,V, to the separation distance, d.

V = 360 V

d = 45 mm = 0.045 m

E = \dfrac{V}{d} = \dfrac{360}{0.045} = 8000

b. The force on a charge in an electric field is the product of the field and the charge.

F = qE

With the charge, q, known, the force can be calculated.
