Answer:
a hypothesis is a explanation made on the basis of limited evidence
Explanation:
Lines of longitude and latitude . Surprisingly, almost all sunspots are found in two bands on the Sun, just north and south of the equator. At the start of the cycle, the sunspots appear at latitudes of about 30 degrees, both north and south<span> of the equator.</span>
Its D because of the emission spectra
Answer:
In the second case there's no way to know what depth the bullet will penetrate into the block.
Explanation:
Since the block is on a <em>frictionless </em>surface, when hitted by the bullet, this last one could barely penetrate the surface of the block and, both, start moving as one (<em>perfectly inellastic collition</em>) since here, there's no vise to hold the block into place.
Answer:
Object A
Explanation:
given,
Object A
mass,m₁ = 1.4 Kg
speed of the car,v₁ = 14.2 m/s
object B
mass,m₂ = 2 Kg
speed,v₂ = 5 m/s
Kinetic energy of the object will be absorbed by you when it hit you.
KE₁ = 141.148 J
kinetic energy of the object B
KE₂ = 25 J
Hence, the Object A will feel worse if hit you because of the kinetic energy of the object A is more.
