Mrs. Waid drives her car up Route 8 at 80mph. If her car weighs 2500 lbs,
Shtirlitz [24]

Answer:

It have 1.359 joule kinetic energy.

Explanation:

  • Kinetic energy is defined as the energy of any object due to its state of motion.
  • Mathematically kinetic energy can be calculated as:

                                    K.E = \frac{1}{2}mv^{2} ...........................equation 1

        where,

           m= mass of object

           v= velocity of that moving object

  • In the above problem;

                     mass= 2500 lbs = 5511.56 kg.

                     velocity= 80mph= \frac{80}{60*60} m/s = 0.0222 m/s.

  • Substituting the values in equation 1, we get;

                                    K.E= \frac{1}{2} * 5511.56 * 0.0222^{2}

                                   K.E= 1.359 joule.

When 0.250 moles of licl are added to 200.0g of water in a constant pressure?
Mariana [72]
Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g

ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C

If a car changes its velocity from 32 km/hr to 54 km/hr in 8.0 seconds, what is its acceleration?
Stella [2.4K]
Use the equation for the acceleration
A = final velocity - initial velocity divided by time final - time initial
A= 54 - 32 / 8 - 0
A= 22 / 8 
A= 2.75 m/s^2 
Hope this helps!

In dealing with every task assigned, why is planning important for a student?
Jet001 [13]

Answer:

Having a planner gives students freedom to plan, organize and keep track of their work to the best of their abilities and requirements. This has a dual benefit in that it increases the student's accountability to the commitments planned as well as provides them with a structure that contributes to their success.
