Answer:
F = 33.12 N
Explanation:
given,
first force = 15 N is oriented at 58.0° counterclockwise
second force = (−19.0 N,18.5 N)
x-component of first force = 15 cos 58.0° = 7.95 N
y-component of second force = 15 sin 58.0° = 12.72 N
second component
now,
F netx = 7.95 - 19 = -11.05 N
F nety = 12.72 + 18.5 = 31.22 N
F = 33.12 N
θ = -70.51°
They have a negative oxidation number because nonmetals gain electrons, thus making them negatively charged ions (anions). Metals become cations and have a positive charge because they lose electrons.
Answer:
1km = o.621371 mile
Explanation:
1.609 kilometers equal 1 mile. The kilometer is a unit of measurement, as is the mille. However, a mile is longer than a kilometer.
The correct option is PROVIDE ELECTRICAL ENERGY.
The marked cell in the given electric circuit is the battery and the function of the battery in electric cells is to provide electrical energy that will drive the electrical current in the electric circuit. A battery in an electric circuit is thus a source of energy for the circuit.
I'm pretty sure that you have mass. When it comes to gravity, anything that has mass behaves exactly like anything else that has mass. Any two of them are attracted to each other, with a force that's proportional to the product of their masses, and inversely proportional to the square of the distance between them.
Now, if you have mass, then you have weight ... it's the answer you give when somebody asks "How much do you weigh ?". That's the force of gravity between you and the Earth, pulling you toward the center of the Earth. But it doesn't stop there. There's also a force of gravity pulling the Earth toward the center of you. The strength of it is EQUAL to your weight.
Your weight on Earth is EQUAL to the Earth's weight on YOU !
