Answer: See explanation
Explanation:
From the information given, we are informed that an instrument rated pilot is planning a flight under IFR on July 10, this year.
It should be noted that before conducting the flight, the pilot must have performed and logged the prescribed tasks and repetitions that are required for instrument currency no earlier than January, 10 for the year.
Answer:
a - 3
, b - 2
, c-- 2
, d - 1
Explanation:
In this exercise we must relate the different physical processes with the force responsible for the process:
a. Neutron decay
the disintegration of the neutral is an example of the weak interaction
a - 3
b. The Earth pulls the Moon.
In this case as the two bodies and with great mass, the interaction is the gravitational interaction
b - 2
c. gravitational interaction
c-- 2
d. Protons repel other protons in the nucleus.
Since the two particles have a positive charge, the interaction is electromagnetic
d - 1
missing the case of the strong interaction that is responsible for the attraction of proton proton and proton neutron within the nucleus
D<span> Jupiter is </span>2.5 times<span> more massive than all of the other planets in our Solar System combined</span>
Answer:
Friction between the box and the floor is 25N to the left
Explanation:
There are two forces acting on the box along the horizontal direction:
- The force of push applied by the worker, in the forward direction, F
- The force of friction, 
, acting in the opposite direction (backward)
So the net force acting on the box is
According to Newton's second law of motion, the net force on an object is equal to the product between its mass (m) and its acceleration (a), so we can write:
And so
However, in this case the box is moving at constant speed; this means that its acceleration is zero:
Therefore we have:
Which means
And since we are told that
This means that the force of friction is also 25 N:
