How much heat does it take to raise the temperature of 9.0 kg of wood from 12c to 97c? the specific heat of wood is 1.68 kj/(kgc). use q = mc(tf - ti). a. 760 kj b. 1300 kj c. 180 kj d. 1500 kj

Explanation:

As we know that heat require to change the temperature of the object is given as

here we know that

m = mass = 9 kg

C = 1.68 kJ/kg

now from above formula we will have

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
