Answer:
Explanation:
Given
mass of ice
Final temperature of liquid
Specific heat of water
Latent heat of fusion
Latent heat of vaporization
Suppose M is the mass of steam at
Heat required to melt ice and convert it to water at
Heat released by steam
and must be equal as the heat gained by ice is equal to Heat released by steam
As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur. <span>During a chemical reaction, new substances are produced as existing bonds are broken, atoms are rearranged, and new bonds are formed.</span>
Answer:
The net force acting on that object must be 0
Explanation:
According to Newton's first law of motion, if there's no force acting on an object (or the net force is 0), that object will stay at the same speed. That object acceleration must also be 0.
Answer:
the object will move
Explanation:
well if you push an object it will move.
Answer:
The magnitudes of the net magnetic fields at points A and B is 2.66 x T
Explanation:
Given information :
The current of each wires, I = 4.7 A
dH = 0.19 m
dV = 0.41 m
The magnetic of straight-current wire :
B= μI/2πr
where
B = magnetic field (T)
μ = 1.26 x (N/)
I = Current (A)
r = radius (m)
the magnetic field at points A and B is the same because both of wires have the same distance. Based on the right-hand rule, the net magnetic field of A and B is canceled each other (or substracted). Thus,
BH = μI/2πr
= (1.26 x )(4.7)/(2π)(0.19)
= 4.96 x T
BV = μI/2πr
= (1.26 x )(4.7)/(2π)(0.41)
= 2.3 x T
hence,
the net magnetic field = BH - BV
= 4.96 x - 2.3 x
= 2.66 x T
