Energy can only be converted from one form to another
eg kinetic energy is converted to heat energy
A. 2 C₂ H₆ + 7 O₂ → 4 C O₂ + 6 H₂ O
according to law of conservation of mass , the total mass of reactants side must be same as the total mass of product side. so we need to check if each atom in the equation has same number on both side of the equation or not.
in this equation , we have
4 atoms of carbon left and 4 atoms of carbon on right
12 atoms of hydrogen on left and 12 atoms of hydrogen on right
14 atoms of oxygen on left and 14 atoms of oxygen on right
Gravitational potential energy is the higher it us above the ground the more gravitational potential energy it holds.Sphere 2 says it has three times the mass of sphere 1. Therefore the answer is Sphere 2 since it was raised three time the mass of sphere 1. and the rest of the answer choices dont make sense.
Answer:
The magnetic field inside a coil is 0.0119 T.
Explanation:
Given that,
Number of turns = 228
Current = 0.952 A
Length = 2.29 cm
We need to calculate the magnetic field
Using formula of magnetic field
Where, B = magnetic field
l = length
I = current
N = number of turns
Put the value into the formula
Hence, The magnetic field inside a coil is 0.0119 T.
26).
The complete pattern of a pendulum is ...
-- out to one side
-- back to the center
-- out to the OTHER side
-- back to the center.
So, on the graph, the complete period is one up-loop and one down-loop.
That's <em>6 seconds</em>. (b)
27).
This question is just asking for the frequency, without using the word.
Frequency is always (1/period). That's <em>1/6 of a second</em>. (a)
(This kinda makes sense. If you want to do something in 6 seconds, you need to do 1/6 of it every second. Right ?)
