Since its a sphere, the top is seen first because its the tallest part if the ship. If the earth was flat, the whole ship would be seen.
initial momentum of 2 kg blob is given as
here we have
initial momentum of 3 kg blob is given as
here we have
So initially 2 kg Blob has most momentum before they collide
Answer:
The correct option is (B).
Explanation:
The Kepler's third law of motion gives the relationship between the orbital time period and the distance from the semi major axis such that,
It is mentioned that, an asteroid with an orbital period of 8 years. So,
So, an asteroid with an orbital period of 8 years lies at an average distance from the Sun equal to 4 astronomical units.
Answer:
Magnetic field lines form closed loops around current carrying straight wires.
Explanation:
Magnetic field lines is known to form closed loop (which also serves as a bar magnet) around current carrying conductor in a magnetic field. This direction of the loop around the conductor either clockwise or anticlockwise will determine the direction of current in the conductor.
This directions can be determined using the Maxwell cockscrew or clenched fist rule.
According to clenched fist rule which states if the conductor is grasp with the right hand, the curled finger will point in the direction of the magnetic field and the thumb will point in the direction of the current.
Note that the magnetic field lines around the conductor also behaves like a bar magnet.
Answer:
0.2 m/s
Explanation:
= Mass of glider A= 0.125 kg
= Mass of glider B = 0.375 kg
= Initial Velocity of glider A = 0 m/s
= Initial Velocity of glider B = 0 m/s
= Final Velocity of glider A = 0.6 m/s
= Final Velocity of glider B
As linear momentum is conserved
Magnitude of the glider B at this time is 0.2 m/s
