Answer:

0.5kg

Explanation:

Given parameters:

Speed of the object  = 12m/s

Kinetic energy  = 36J

Unknown:

Mass of the object  = ?

Solution:

Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;

     K.E = \frac{1}{2} m v²  

 Insert the parameters and solve;

    36  =  \frac{1}{2} x m x 12²

     36  = 72m

       m  = 0.5kg

A group of students are measuring how the acceleration of a mass will change when it is acted
Virty [35]

The scatter plot that shows a positive correlation between force and acceleration.

<h3>What is the relationship between acceleration of an object and the applied force?</h3>

The acceleration of an object is the change in velocity with time.

  • Acceleration = change in velocity/time

Force is defined as an agent which causes a change in the motion or state of rest of a body.

According to Newton's law of motion, the rate of change of velocity of an object is directly proportional to the applied force and takes place in the direction of the applied force.

Force and acceleration have a positive correlation.

Therefore, the scatter plot which will most closely match the measurements that the students will obtain is that which shows a positive correlation between force and acceleration.

In conclusion, acceleration of a object is proportional to the applied force.

Determine the volume of 3.30 mol of a gas at 25°C and 0.995 atm.
Alexxx [7]

Answer:

V = 81.14 L

Explanation:

Given data:

Volume of gas = ?

Number of moles = 3.30 mol

Temperature of gas = 25°C

Pressure of gas = 0.995 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Now we will convert the temperature.

25+273 = 298 K

now we will put the values in formula:

V = 3.30 mol 0.0821 atm.L/ mol.K   298 K / 0.995 atm

V = 80.74 L. atm / 0.995 atm

V = 81.14 L

How long would it take for 1.50 mol of water at 100.0 ∘c to be converted completely into steam if heat were added at a constant
Aleksandr-060686 [28]
To determine the time it takes to completely vaporize the given amount of water, we first determine the total heat that is being absorbed from the process. To do this, we need information on the latent heat of vaporization of water. This heat is being absorbed by the process of phase change without any change in the temperature of the system. For water, it is equal to 40.8 kJ / mol.

Total heat = 40.8 kJ / mol ( 1.50 mol ) = 61.2 kJ of heat is to be absorbed

Given the constant rate of 19.0 J/s supply of energy to the system, we determine the time as follows:

Time = 61.2 kJ ( 1000 J / 1 kJ ) / 19.0 J/s = 3221.05 s
