Answer:
The resulting net force is 650N
Explanation:
The force caused by air resistance against the plane's motion is called the Drag force. It acts against the motion of the plane. However, tailwinds push the plane from its tail and they apply a force is the direction of the moving plane.
The resulting force is the sum of the two forces; 450N +200N = 650N
Answer:
A 3.0 kg mass moving at 9.0 m/s has more momentum than taht of a 5.0 kg mass moving at 5.0 m/s
Explanation:
given two masses m1 and m2 and their corresponding velocities v1 and v2
m1 = 3 kg
m2 = 5 kg
v1 = 9 m/s
v2 = 5 m/s
To calculate momentum of the masses:
We know that the momentum is given by the equation:
p = mv, where m is mass and v is velocity
momentum of mass m1 , p1 = m1 x v1
= 3 x 9 = 27 kg.m/s
momentum of mass m2, p2 = m2 x v2
= 5 x 5 = 25 kg.m/s
Hence p1>p2
Comparing above momentum value, it is inferred that the momentum of mass 3.0 kg is more that the momentum of mass 5.0 kg.
If a system allows the exchange of energy but does not permit exchange of matter between the system and surroundings, this system is classified as a CLOSED system. The energy that flows in and out of the system boundaries is in the form of heat.
2.25 amperes
Ohms law dictates that electrical voltage = current times resistance. Since you are given voltage and not the current, you will be dividing voltage by the resistance.
9.0V ÷ 4.0ohms = 2.25 amps
Mark as brainliest if satisfied.
I believe it's Mercury, because the only other option would be Pluto and it's not even considered a planet anymore
Hope this helps
