Answer:
360 Nm
Explanation:
Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Newton- meter (Nm).
From the question,
The expression of torque is given as
τ = F×d......................... Equation 1
Where, τ = Torque, F = force, d = distance of the bar perpendicular to the force.
Given: F = 40 N, d = 9 m
Substitute into equation 1
τ = 40(9)
τ = 360 Nm.
Because a lot of things only live on earth earth is a place where all living this can live in
Answer:
Modern telescopes are capable of seeing bright galaxies up to about 10000 millions light years away
Explanation:
A telescope is a tool that astronomers use to see faraway objects. Most telescopes work by using curved mirrors to gather and focus light from the night sky. The bigger the mirrors or lenses, the more light the telescope can gather.
Modern telescopes gather information from the electromagnetic spectrum far beyond the range of visible light.
The farthest bright galaxies, that the modern telescope is capable of seeing is 10000 millions light years away.
Answer:
Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
Answer:
c. emission of electromagnetic radiation.
Explanation:
When an atom changes its state from an excited one to the ground state, it means that the atom is changing from a state with higher energy to a state of lower energy.
This can occur, for instance, in the presence of an electronic transition (an electron moving from a higher energy level to a lower energy state) or of a nuclear transition (the nucleus get de-excited). In both cases, since the total energy must be conserved, there must be energy released. This energy is released as a photon (electromagnetic radiation), whose energy is equal to the difference between the two energy levels involved in the transition.
