The answer is A. Newton's third law of motion states that for every action, there is an equal and opposite reaction. A rocket exerts a large force on the gas that is in the rocket chamber (action). The gas thus exerts a large reaction force forward on the rocket (reaction). The large reaction force is called thrust.
Answer:
coordinate will be
r = (1.33,4.33)
Explanation:
As we know that if a point will divide two given coordinates in m : n ratio
then in that case the point is given as
here we know that two points are
(-7, -4) and (3, 6)
and the ratio is given as 1 : 5
now from above formula we will have
so coordinate will be
Answer:
49 m/s
Explanation:
Acceleration = velocity / time
You should know accleration due to gravity is 9.8 m/s^2 and you're given t = 5, so you can solve for velocity:
9.8 = v / 5
v = 49
Answer:
= 3.87 m/s
Explanation:
Since momentum is conserved, momentum right before and after the boy jumps onto the skateboard should be the same.
Initial momentum = momentum of boy = 43.2 x 4.10 = 177 kg·m/s
Final momentum = momentum of boy and skateboard = (43.2 + 2.50) x v = 45.7v
177 = 45.7v
v = 177 / 45.7 = 3.87 m/s
(Hope this helps can I pls have brainlist (crown)☺️)
courts have many properties including Mass electric charge and color their Mass tells you something about how much matter they are made of or how heavy they would be if you could wear them up charm and top quarks have a positive 2/3 charge
