Answer:
C 0.85 j/g*k
Explanation:
The specific heat capacity of a material is given by:
where
Q is the amount of heat supplied to the object
m is the mass of the object
is the increase in temperature of the object
For the object in this problem, we have
m = 117 g is the mass
Q = 1200 J is the heat supplied
is the increase in temperature
Substituting into the formula, we find the specific heat:
Answer:
true for first and false for second
Explanation:
It doesn't the sun stays still we move around the sun

U 3.5 -2.5
what is magnitude of resultant vector STU
a. 4.9 b. 24 c. 16. d. 18
Seems right option is not there. The right one will be 7./2 ie 9.9
Power is determined by work/time.
We have P = W/T as our formula.
There is 375J of work, and 11s of time.
Plug in 375J for Work, and 11s for Time.
P = 375/11
Our power is 34.09.
Hope this helps!
