A student throws a 0.46kg bowling ball at a velocity of 25m/s what is the kinetic energy of the bowling ball in Joules

Explanation:

The kinetic energy of an object can be found by using the formula

where

m is the mass

v is the velocity

From the question we have

We have the final answer as

Hope this helps you

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
