Answer:
I think it depends on the purpose of using Gamma rays. It can be both good and bad
Answer:
Explanation:
From the exercise we know that the force on the plane is 7934N upward at an angle of 54.2º.
If analyze the forces in the vertical direction, the acceleration is zero because the plane is moving with constant velocity
∑
So, the <u><em>weight of the plane</em></u> is 6435N
Answer:
x=7227
y=1678
(7227,1678)
Explanation:
Ok, check the picture I attached you, because of the problem don't give us aditional information, let's asume that the projectile is fired from an initial position x=0 and y=0. Now let's use projectile motion equations, but firs let's find the initial velocity components in x-axis and y-axis:
Now, let's find the x coordinate with this equation:
Finally asumming a gravity constant g=9.8, let's find the y coordinate with the next equation:
Answer:
b because we apply Hooke's law
Explanation:
Hooke's law
