Answer:
In physics and engineering, a free body diagram (force diagram, or FBD) is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition.
Answer:
Electromagnetic waves can travel through empty space.
Explanation:
Electromagnetic waves are defined as the waves that are created due to the vibrations between a magnetic field and an electric field.
Earth atmosphere is made up of several gases and spaces between them. Thermal energy from the sun require to pass through space by electromagnetic radiation. Electromagnetic waves can travel through empty space and that is why other type of waves are unable to transfer thermal energy.
Hence, the correct answer is "Electromagnetic waves can travel through empty space".

Answer:
Explanation:
For a charged particle moving perpendicularly to a magnetic field, the magnitude of the force exerted on the particle is:
where
q is the magnitude of the charge of the particle
v is the velocity of the particle
B is the magnetic field strength
In this problem, we have
is the charge of the electron
is the velocity
is the magnetic field
Substituting into the formula, we find the force:
Answer: B. Rhyolitic
Rhyolitic magma is responsible for most violent volcanic eruptions. Rhyolitic magma erupts catastrophically with high intensity gas content. This magma being more viscous traps gases, builds pressures and erupts explosively. High viscosity of this magma is because of high silica content that erupt with the mineral contents of the rocks.
