Gravity. That's the only force between the two objects.
Answer:
Density
Explanation:
Waves are periodic disturbances that travel in a medium by carrying energy without carrying matter.
There are two types of waves:
- Mechanical waves: these are produced by the vibrations of the particles in a medium. An example of mechanical waves are sound waves. Mechanical waves can only propagate through a medium, while they cannot travel in a vacuum.
- Electromagnetic waves: these consist of the oscillations of electric and magnetic fields in a direction perpendicular to the propagation of the wave. These are the only type of waves that can travel in a vacuum, since they do not need a medium.
The speed of a wave is the speed at which the wave propagates through the medium / the vacuum.
For mechanical waves, the speed of a wave in a solid material is given by
where
B is the bulk modulus of the medium
is the density of the medium
Therefore, from the formula we see that the wave speed depends on the density of the medium, while the other quantities (volume, electric charge) are not involved.
For liquids and gases, the wave speed is obtained through a different formula, however it still depends on the density of the material. So the correct answer is
a) Density
I think that your answer should be D) the state should make use of satellites and radars because they detect when a storm is coming
Answer:
The acceleration caused by a net force of 2 N on a 2 kg mass is 1 m/s²
Explanation:
The given parameters on an applied force is as follows;
The acceleration given to a 1 kg mass by a 1-N net force = 1 m/s²
According to Newton's second law of motion, the acceleration, "a", given to an object by a force, "F", is proportional to the magnitude of the net force
Therefore, we have;
F ∝ a
The constant of proportionality is given as the mass, "m", of the object, therefore, we have;
F = m × a
The acceleration given to a 2 kg mass by a 2-N net force is given therefore, given as follows;
2 N = 2 kg × a
a = 2 N/(2 kg) = 1 m/s²
The acceleration, "a", caused by a net force of 2 N on a 2 kg mass is a = 1 m/s².
Answer:
Inertia
Explanation:
People can float in space since there is no gravity. Pretty Simple? The reason why thingsvlike planets and stars don't move is due to Inertia, which keeps the things in line in the solar system.
