Answer:
denisity = 52.33 g/c
Explanation:
Density:
We have that m = 785 and that v = 15 c.
d = 52.33
Answer:
a. 1 Newton = 100000 Dyne
b. a represents acceleration.
Explanation:
Newton is the standard unit (S.I) of measurement of force. Converting 1 Newton to dyne we have;
1 Newton = 10⁵ Dyne
1 Newton = 100000 Dyne
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Hence, we can deduce that a represents the acceleration of an object and it's measured in meters per seconds square.
Answer:
I think it's TRUE because forces change an object's motion but dont quote me on it ok? Cause I'm not a 100 percent sure
Note that
The specific heat of water is 4.184 J/(g -C)
Let x = the final equilibrium temperature.
Heat loss by the copper is
(155 g)*(0.385 J/(g -C))*(168 - x C) = 59.675(168 -x) J
Heat gain by the water is
(250 g)*(4.184 J/(g-C))*(x - 20.9 C) = 1046(x - 20.9) J
Because there is no heat loss to the surroundings, therefore
59.675(168 - x) = 1046(x - 20.9)
168 - x = 17.5283(x - 20.9)
18.5283x = 534.3415
x = 28.84 °C
Answer: 28.8 °°C nearest tenth)
