The forces that push upward on an indoor skydiver are lift force and air resistance.

The forces that act on a skydiver moving downwards includes, gravity due to his weight, air resistance and lift force.

The downward forces on the indoor skydiver include the following;

  • <em>gravity due to its weight</em>
  • <em>downward force due its acceleration</em>

<em />

The upward force on the indoor skydiver include the following;

  • <em>lift force</em>
  • <em>air resistance</em>

Thus, we can conclude that the forces that push upward on an indoor skydiver are lift force and air resistance.

The advantage of a synchronous orbit is that the satellite can: fly over the entire earth transmit over the entire earth receive
dsp73

Answer:

<u>receive continuous signals from a ground transmitter</u>

Explanation:

Remember a <u>synchronous orbit is synchronous in the sense that it has equal rotational period to the body orbiting having the same direction of rotation as that body</u>. An example of this is the Moon and the planet earth.

Thus it allows continuous signals to be sent from a ground transmitter and received by a space object.

Un ladrón viaja en un auto a una velocidad excesiva de 30m/s, en dicho momento un policía de tránsito, lo observa y monta en su
tester [92]

Answer:

t = 12 s

Explanation:

To find the time in which the police reaches the thief you write the equation of motion of both thief and police:

The thief has a constant velocity, the position is then given by:

x=vt     (1)

The police has an acceleration, then the position is:

x=v_ot+\frac{1}{2}at^2   (2)

the time in which the police reaches the thief is when their positions are equal, that is, when expression (1) equals expression (2). But before you calculate the acceleration of the police:

a=\frac{v-v_o}{t}\\\\v_o=0m/s\\\\a=\frac{50m/s}{10s}=5\frac{m}{s^2}

you replace this values in (2) and you equal the expression (1) and (2) (with vo = 0):

vt=\frac{1}{2}at^2\\\\\frac{1}{2}at^2-vt=0\\\\(\frac{1}{2}at-v)t=0

one root is t = 0s, but it is omitted because is the momment in which the thief pass in front of the police. The other root is:

\frac{1}{2}at-v=0\\\\t=\frac{2v}{a}=\frac{(2)(30m/s)}{5m/s^2}=12s

hence, the time is 12 s

Work=Force \: × \: displacement \\ => W=Fs \\  \\ Given, \\ Force=25 \: N \\ Displacement=2m \\  \\ so \: work = 25 \: N \:  \times 2m \\  =  > work = 25kgm {s}^{ - 2} \times 2m \\  =  > work = 50kg {m}^{2} {s}^{ - 2}  \\  =  > work = 50J

This is the answer.

Hope it helps!!
