What else can I help you with?
What The weight of an object is constant true or false?
False. The weight of an object can vary depending on the gravitational force acting upon it.
True or false are Magnetic poles called domains?
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
As the mass of an object increases so does its gravitational force true or false?
True. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses. Therefore, as the mass of an object increases, its gravitational force also increases.
When a wire with a current is placed in a magnetic field electrical energy is transformed into mechanical energy true or false?
False. When a wire with a current is placed in a magnetic field, the interaction between the magnetic field and the current in the wire creates a force known as the Lorentz force. This force is responsible for generating mechanical motion, not transforming electrical energy into mechanical energy.
Magnetic forces can repel without touching True or false?
True. Magnetic forces can repel objects without them physically touching because the magnetic fields generated by the objects interact to create a repelling force.
When an astronaut is in space his or her body is acted upon by an increased gravitational force from the Earth True or False?
this answer is false because when you go into space you start to float. So the answer is false. You loose the gravitational pull not gain gravitational pull.
What The weight of an object is constant true or false?
False. The weight of an object can vary depending on the gravitational force acting upon it.
Only the earth exerts gravitional force on all object is it true or false?
False. Every object attracts every other object, through the gravitational force.
True or false The Moon orbits Earth and not the Sun because the Sun doesn't exert a gravitational force on the Moon?
False. The Moon orbits around Earth due to Earth's gravitational pull, but the Sun also exerts a gravitational force on the Moon. The combined gravitational forces of Earth and the Sun control the Moon's orbit.
True or false are Magnetic poles called domains?
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
As the mass of an object increases so does its gravitational force true or false?
True. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses. Therefore, as the mass of an object increases, its gravitational force also increases.
The moon orbits earth and not the sun because the sun doesn't exert a gravitional force on the moon True or False?
False. The sun does exert a gravitational force on the moon.
True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
When a wire with a current is placed in a magnetic field electrical energy is transformed into mechanical energy true or false?
False. When a wire with a current is placed in a magnetic field, the interaction between the magnetic field and the current in the wire creates a force known as the Lorentz force. This force is responsible for generating mechanical motion, not transforming electrical energy into mechanical energy.
Magnetic forces can repel without touching True or false?
True. Magnetic forces can repel objects without them physically touching because the magnetic fields generated by the objects interact to create a repelling force.
Earth exerts an unbalanced force on a ball thrown into the air True or false?
True. When a ball is thrown into the air, Earth's gravitational force causes the ball to accelerate downward, creating an unbalanced force.
As the mass and distance between two objects decrease so does the gravitational force exerted between them true or false?
False. Gravitational force is actually directly proportional to the masses of the two objects and inversely proportional to the square of the distance between them. This means that as the mass increases or the distance decreases, the gravitational force between the two objects will increase.
