Answer:

First choice

Explanation:

A satellite in orbit around Earth experiences only one force: the gravitational attraction exerted by the Earth on it. This force is labelled with $F_g$ . In space, there are no other forces acting on the satellite.

The force of gravity acts as centripetal force, "pulling" the satellite towards the centre of its circular orbit. The inertia of the satellite (which has an initial velocity) tends to keep it moving straight, so the combination of these two effects (inertia and force of gravity) results into the circular motion of the satellite.

7nadin3 [17]

The change in angular displacement as a function of time is the definition given for angular velocity, this is mathematically described as

$\omega = \frac{\theta}{t}$

Here,

$\theta$ = Angular displacement

t = time

The angular velocity is given as

$\omega = 230rev/min$

PART A) The angular velocity in SI Units will be,

$\omega = 230rev/min (\frac{1min}{60s})(\frac{2\pi rad}{1rev})$

$\omega = \frac{23}{3}\pi rad/s \approx 24.08rad/s$

PART B) From our first equation we can rearrange to find the angular displacement then

$\theta = \omega t$

Replacing,

$\theta = (24.08)(0.75)$

$\theta = 18.06 rad$

Correct answer choice is :

C) To see if samples contain the target dna

Explanation:

In many North American rivers, populations of various kinds of non-native cyprinid fishes are present, including black carp, grass carp, bighead carp, silver carp, common carp, and goldfish. All six of these classes are found in the Mississippi River basin and following their aggression has shown complex, especially where wealth is low. The bighead carp is a species of freshwater fish, one of several Asian carps. It is one of the most intensively exploited fishes in aquaculture, with a yearly global product of over three million tonnes in 2013, mostly from China.

A speedboat moving at 29.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant accelerati

Goshia [24]

Answer:

$t =4.8sec$

Explanation:

From the question we are told that

Velocity of speed boat $V=29.0m/s$

Distance to Marker $d=100$

Acceleration of $a=-3.4m/s^2$

Generally the Newtons 3rd motion equation is given as

$v^2 = u^2 + 2 * a* s$

$v^2 = 29^2 + 2 * -3.4* 100$

$v = \sqrt{161}$

$v=12.68m/s$

Generally the Newton's first equation of motion is given as

$v = u + a*t$

$12.68 = 29 -3.4*t$

$12.68-29 = -3.4t$

$-16.32 = -3.4t$

$t =\frac{-16.32}{-3.4}$

$t =4.8sec$ .
