Answer:
10.1 °C
Explanation:
After the mixture, heat is gained by the soapstone cubes (they were at a lower temperature) while heat is lost by the whisky (it was at a higher temperature).
Let the temperature of the mixture be <em>T</em>.
Heat lost by whisky,
is the mass of the whisky (in kg), is the specific heat of whisky (J/kg·K) and is the change in temperature of the whisky (in °C or K).
Heat gained by soapstone cubes,
There are three cubes of soapstone, so their mass is multiplied by 3.
From the principle of mixtures,
Heat lost by whisky = Heat gained by soapstone cubes (assuming no heat loss to the surroundings)
The final temperature of the whisky is 10.1 °C.
m=1800 kg has the greatest momentum
<u>Explanation:</u>
Linear momentum is defined as the product of mass and velocity of a body. It is directly proportional to mass and velocity and is given by the expression
P=mv
where P denotes linear momentum,m denotes mass and v denotes velocity.
given that
velocity of both objects is v=5 m/s
Mass of the first object m=
Mass of the second object m=1800 kg
velocity of both objects is same. The second object has higher mass than first.
When mass increases, momentum increases with it.
Thus the second object with m=1800 kg has higher momentum than first.
Answer:
While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.
