To solve the problem, we
must know the heat capacity of ice and water.
For Cp = 2090 J/kg C
H = mCpT
H = (10 kg) ( 2090 J/ Kg C)
( -23 C)
H = - 480700 J
For water Cp = 4180 j/kg C
H = (100 kg) ( 4180 J/kg C)
( 60 C)
<span>H = 2508000 J</span>
Answer:
a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
Explanation:
Answer:
Explanation:
1) Displacement of the object will be gotten using simply adding the distances since they are goinf in the same direction (positive y direction)
Displacement= 330km + 220km
Displacement = 550km North
2) For a falling body, the body will possess positive acceleration due to gravity because it is falling under the influence of gravitational force. If a body is not under the influence of gravity and is thrown up, such body wont come back down. Hence the value of acceleration due to gravity of a body falling to the ground is +9.8 m/s² (note that the unit of acceleration is m/s²)
I believe the answer is pressure. hope this helps
Explanation:
Given
mass of the rock is 10 kg
Force requires to hold the rock is equal to its weight
Weight is given by the product of mass and acceleration due to gravity
Weight on the earth surface
Weight on the moon surface
So, the force holding the rock on earth is approximately 6 times the force on the moon.
