Answer:
The arrow was moving at 16.2 m/s
Explanation:
The law of conservation of energy says that the kinetic energy of the arrow must be converted into the potential energy of the block and arrow after it they join:
where is the mass of the arrow, is the mass of the block, of the change in height of the block after the collision, and is the velocity of the arrow before it hit the block.
Solving for the velocity v, we get:
The arrow was moving at 16.2 m/s
Answer:
I do believe it is A it makes the most since
Answer:
<h2>Magnetic field strength in that region is 1.2 T</h2>
Explanation:
As we know by the formula of radius of charge moving in external field is given as
so we will have
now we have
now we have
Answer:Intensity: The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Magnitude: Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by an earthquake.
