Answer:
The current is 7.87 A.
Explanation:
Given that,
Length = 0.250 m
Magnetic field 
Magnetic force = 0.120 N
We need to calculate the current
Using formula of magnetic force


Where, B = magnetic field
I = current
l = length
F = force
Put the value into the formula


Hence, The current is 7.87 A.
Answer:
1.6 m/s²
Explanation:
Weight equals mass times acceleration due to gravity.
F = mg
14.4 N = (9 kg) g
g = 1.6 m/s²
This problem can be solved by using oxidation states. The oxidation state is based on the electrons an atom loses or gain, or appears to use when forming compounds.To find the formula for Copper (I) Sulfide, we have to first consider the individual ions that come together to form it. Copper (I) is an ion of copper that has a charge of +1, i.e
. Sulfur is an element in group 6 of the periodic table. The sulfur ion has a charge of -2, i.e
. To form Copper (I) Sulfide, which is electrically neutral, we need 2 Copper (I) ions and 1 sulfur ion.
.
The reaction is represented by the equation below
.
The correct answer is (C)
Equilibrium is the answer because they are reaching an equal temperature
It is most accurate to say that body mass index (BMI) provides information about an individual's height-weight ratio. The correct answer is B.
