Answer:
where is the diagram..........
Answer:
Unknown
Explanation:
Because we cannot observe space beyond the edge of the observable universe, it is unknown whether the size of the Universe in its totality is finite or infinite.
If two vectors are represented both in magnitude and direction by the two adjacent sides of a triangle taken in an order, then their resultant is given by the third side taken in the reverse order.
Resultant vector :
R = sqrt of A^2 + B^2 + 2ABcosθ
given :
A = 200 units
B = 300 units
θ = 30 degrees
∴ R = sqrt of 200^2 + 300^2 + 2(200)(300)cos35
the answer is 477.805656
Answer:
Q = 142.324kJ
Explanation:
Data:
M = 500g = 0.5kg
T1 = 10°C = (10 + 273.15)K = 285.15K
T2 = 80°C = (80 + 273.15)K = 353.15K
Q = ?
C = 4186J/kg.K
Q = mc(T2 - T1)
Q = 0.5 * 4186 * (353.15 - 285.15)
Q = 0.5 * 4186 * 68
Q = 142324J
Q = 142.324kJ.
