Answer:
The answer is C... I am almost positive.
You are given
200 grams of H2O(s) at an initial temperature of 0°C. you are also given the
final temperature of water after heating at 65°C. You are required to get the
total amount of heat to melt the sample. The specific heat capacity, cp, of
water is 4.186 J/g-°C. Let us say that T1 = 0°C and T2 = 65°C. The equation for
heat, Q, is
Q = m(cp)(T2-T1)
Q = 200g(4.186
J/g-°C )(65°C - 0°C)
<u>Q =
54,418J</u>
Answer:
The force must be in the same direction as the object’s motion
Explanation:
Force is a physical quantity.
It is defined as the force applied to a body to move it in the direction of the force applied.
Force = mass x acceleration.
- Force results in the acceleration of a body.
- Force causes the change in position of a body and it moves it towards the direction of the applied force.
- A force is a vector quantity having both magnitude and direction.
So, option is C is the correct choice.
