Answer:
the correct statement is the first
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products.
Explanation:
The law of conservation of energy establishes that the masses are not destroyed, they can only be transformed.
Therefore the mass of carbon in the reactants (CO2 and H2O) must be in the products (glucose and oxygen)
so the correct statement is the first
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products.
The mass of the object doesn't matter. The change in its momentum is equal to the impulse that changed it ... 15 N-sec.
Answer:
B. i=2.79A
C. F=0.066N
Explanation:
A) By the right hand rule we have that
F=iL x B
F=iLBsin(α)
If the wire jump toward the observer the top pole face is the magnetic southpole.
B) The diameter of the pole face is 15cm. We can take this value as L (the length in which the wire perceives the magnetic field). Hence, we have
C) Now the length of the wire that feels B is
and the force will be (by taking the degrees between the magnetic field vector and current vector as 80°)

Answer:
Explanation:
Given that
F(x) = (2.00 N/m) x +(1.00 N/m3) x3.
Which can be written as
F(x) = 2x +x³ N/m
Potential energy from x=1 to x=2
P.E is given as
P.E=∫F(x)dx
P.E=∫2x+x³ dx. From x=1 to x=2
P.E= 2x²/2 + x⁴/4 from x=1 to x=2
P.E= x² + x⁴/4 from x=1 to x=2
P.E=(2²+2⁴/4)-(1² +1⁴/4)
P.E=(4+4)-(1+1/4)
P.E, =8-5/4
P.E=27/4
P.E=6.75J
Since it is moving from lower position to upper position, then P.E should be negative
P.E = - 6.75J
