Answer:

m = 75 Kg

Explanation:

Given data:

Energy = 33750 J

Speed of object = 30 m/s

Mass of an object = ?

Solution:

Formula:

E = 1/2mv²

by putting values,

33750 J = 1/2 × m × (30 m/s)²

m = 2×33750 J/ (30 m/s)²

m = 67500 J /900 m²/s²

J = kgm²/s²

m = 75 Kg

Discuss the effect of changing the flow tube radius on flow rate.
dmitriy555 [2]

Answer:

The flow rate of a tube is the volume of fluid flowing through the tube per unit time. The flowrate is proportional to the product of the velocity of the fluid through the tube, and the cross-sectional area of the tube.

That is

Q = AV

where

A is the area of the tube

V is the velocity of the tube

The cross-sectional area of the tube is proportional to the radius of the tube. From the above equation, we can deduce that if the velocity of the fluid flowing through the tube is held constant, the flowrate of the fluid through the tube will increase with an increase in the radius of the tube, and it will decrease with a decrease in the radius of the tube.

The mass of sodium chloride at the two parts are mathematically given as

  • m=10,688.18g
  • mass of Nacl(m)=39.15g

<h3>What is the mass of sodium chloride that can react with the same volume of fluorine gas at STP?</h3>

Generally, the equation for ideal gas is mathematically given as

PV=nRT

Where the chemical equation is

F2 + 2NaCl → Cl2 + 2NaF

Therefore

1.50x15=m/M *(1.50*0.0821)

1-50 x 15=m/58.5 *(1.50*0.0821)

m=10,688.18g

Part 2

PV=m'/MRT

1*15=m'/58.5*0.0821*273

m'=39.15g

mass of Nacl(m)=m'=39.15g
