Answer:
ya thats right
Explanation:
here is one explanation i found on the web:
Answer: The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Explanation:
The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.
The electromagnetic force is created by the magnetic field and the electric field.
The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.
Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.
Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
The correct answer is 42. I know this answer is right because i have already turned my assignment in and got it right.
B-The body could break down proteins from muscles for energy.
Answer:
0.02564 kg ore contain 10.0 g of nickel.
Explanation:
Given data:
Percentage of nickel in ore = 39.0%
Mass of ore required to have 10 g of nickel = ?
Solution:
39.0% means that 39.0 g of nickel is present in 100 g of ore thus,
39/100 = 0.39
0.39 × X = 10.0 g
X = 10.0 g/0.39
X = 25.64 g
Gram to kilogram:
25.64 g × 1kg /1000 g
0.02564 kg
