A box has the weight of 120N and the bottom of the box is 12 cm² what is the pressure the box exerts on the floor
Molodets [167]

100000N/m²

Explanation:

Given parameters:

Weight of the box = 120N

Area of the box = 12cm²

Unknown:

Pressure of the box on the floor = ?

Solution:

Pressure is the force exerted by a body per unit area:

            Pressure = \frac{force }{area}

We need to convert the area into m² from cm²

     10000cm²  = 1m²

      12cm²  =     \frac{12}{10000} = 0.0012m²

 Pressure = \frac{120}{0.0012} = 100000N/m²

What volume of beaker contains exactly 2.23x10^-2 mol of nitrogen gas at STP?
nikklg [1K]

Answer:

V = 0.5 L

Explanation:

Given data:

Moles of nitrogen = 2.23×10⁻² mol (0.0223 mol)

Temperature = 273 K

Pressure = 1 atm

Volume = ?

Solution:

PV = nRT

V = nRT / P

V = 0.0223 mol × 0.0821 atm. mol⁻¹. L . k⁻¹ × 273 K / 1 atm

V = 0.5 L

Natasha2012 [34]

Answer:

A. the​ bond's yield to maturity is equal to its coupon rate.

Explanation:

The coupon rate is that amount of bond measured on the loan amount whereas the maturity yield is the rate held up to the settlement date and the investment arise up to the maturity date.

Since the bond is currently trading at its face value that means the bond price is equal to the face or par value
