Hello!
The balloon explodes, because the pressure builds up inside and the air want to expand. Letter a)
Hugs!
Actually the image that he will see depends of the lens used during the experience. But normally with good light and properly focus it would be possible to see the finger prints like in the image.
The velocity of the package after it has fallen for 3.0 s is 29.4 m/s
From the question,
A small package is dropped from the Golden Gate Bridge.
This means the initial velocity of the package is 0 m/s.
We are to calculate the velocity of the package after it has fallen for 3.0 s.
From one of the equations of kinematics for objects falling freely,
We have that,
v = u + gt
Where
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
and t is time
To calculate the velocity of the package after it has fallen for 3.0 s
That means, we will determine the value of v, at time t = 3.0 s
The parameters are
u = 0 m/s
g = 9.8 m/s²
t = 3.0 s
Putting these values into the equation
v = u + gt
We get
v = 0 + (9.8×3.0)
v = 0 + 29.4
v = 29.4 m/s
Hence, the velocity of the package after it has fallen for 3.0 s is 29.4 m/s

Newton's first law establishes the following:
An object will remain at rest or with uniform rectilinear motion unless an external force acts on it.
Therefore, we have that a case contrary to Newton's first law is:
Unbalanced forces acting on an object at rest, cause the object to remain at rest.
It is false, because if the forces are unbalanced, then the object will not remain at rest because external forces act on the object.
Answer:
A situation that is contrary to Newton's first law of motion is:
An object at rest stays at rest as long as unbalanced forces act on it.
Answer:
False.
Explanation:
This question refers to the rules of American Football. Thus, the line of scrimmage is an imaginary boundary that is established between both teams, to which the offensive line and the defensive line go to start the play.
In this situation, the offensive team must have 7 players in its formation, but within this some players can perform certain movements, with which it is incorrect to say that the formation cannot be modified, since it is constantly seen as some players, such as wide receivers, for example, move during scrimmage formation.
