Answer: Instantaneous speed.
Explanation:
Incandescence is light at high temp
Answer:
0.25223 seconds.
Explanation:
= Mass of bullet = 0.0146 kg
= Mass of block = 2.55 kg
v = Combined velocity
= Velocity of bullet = 816 m/s
g = Acceleration due to gravity = 9.81 m/s²
As linear momentum is conserved

Now
as the block (with the bullet in it) reverses direction and rises,

Equation of motion

The time t is 0.25223 seconds.
Answer:A the two wire will attract each other
Explanation:
When current is flowing in a wire it is surrounded by magnetic field whose direction can be given by right hand thumb rule.
If current is in direction of your thumb then wrapping of fingers will give the direction of magnetic field.
If two wires with current in same direction flows then the combined magnetic field will be constructive in nature and thus they attract each other.
force on second wire due to first wire is
which will be towards the first wire
D.On the ocean floor. When tectonic plates move, They move along the ocean floor, which is the crust, and It causes earthquakes and volcanoes and also caused Pangea to break apart and become what it is now The seven continents.
