Answer:
0.71121 km/s
Explanation:
= Velocity of planet initially = 54 km/s
= Distance from star = 0.54 AU
= Final velocity of planet
= Final distance from star = 41 AU
As the angular momentum of the system is conserved
When the exoplanet is at its farthest distance from the star the speed is 0.71121 km/s.
The impulse is equal to the variation of momentum of the object:
where m is the mass object and
is the variation of velocity of the object.
The ball starts from rest so its initial velocity is zero:
. So we can rewrite the formula as
or
and since we know the impulse given to the ball (I=16 Ns) and its mass (m=2 kg), we can find the final velocity of the ball:
Answer:
Explanation:
The velocity of plane relative to earth is given by:
As the from given data.The velocity of plane relative to air is:
According to relative motion of velocity of the air relative to earth given by:
The magnitude is given as:
The new fuse will not blow up when a higher current is flowing and the circuit wont be broken and high current can heat up the object and cause a fire boom
The displacement distance from my house to school never changes but the time it takes varies due to traffic and it's effects on my vehicle's speed and position in line at stop lights.
