No, we can not add the magnitudes of those two forces.

<h3>What is Gravitational Force?</h3>

An attractive force between masses is a gravitational force. According to Isaac Newton's second law, F = ma, a gravitational force generates an acceleration just like all other forces do. Remember that according to Newton's second law, a body will accelerate if there is a net force acting on it in an inertial frame of reference (a coordinate system travelling at a constant speed). According to Newton's Universal Law of Gravitation, when two bodies, such as the Earth and the Sun, are in close proximity to one another, an attractive force naturally attracts them. This attraction results in an acceleration of the two objects.

A 50 kg wooden crate is slid across a flat surface for 60 meters by a force of 90.0 N. If the coefficient of sliding friction is
Alika [10]

The final speed of the crate is 6.3 m/s

Explanation:

Please note that there is a typo in the text of the question: the coefficient of sliding friction is 0.15, not 9.15.

First of all, we need to find the force of friction acting on the crate. This is given by:

F_f = \mu mg

where:

\mu=0.15 is the coefficient of friction

m = 50 kg is the mass of the crate

g=9.8 m/s^2 is the acceleration of gravity

Substituting,

F_f = (0.15)(50)(9.8)=73.5 N

Now we can find the acceleration of the crate by using Newton's second law:

F-F_f = ma

where

F = 90.0 N is the force applied forward on the crate

F_f = 73.5 N is the force of friction, acting backward

a is the acceleration of the crate

Solving for a,

a=\frac{F-F_f}{m}=\frac{90.0-73.5}{50}=0.33 m/s^2 in the forward direction.

Finally, we can find the final speed of the crate by using suvat equations:

v^2-u^2 = 2as

where:

v is the final speed

u = 0 is the initial speed

a=0.33 m/s^2 is the acceleration

s = 60 m is the distance covered

Solving for v,

v=\sqrt{u^2+2as}=\sqrt{0+2(0.33)(60)}=6.3 m/s

what aspect of receiver analog-to-digital conversion determines the maximum receive bandwidth of a direct digital conversion sdr
Zepler [3.9K]

Answer:

The sample rate determines the maximum receive bandwidth of a direct digital conversion SDR. An analog signal must be sampled at twice the rate of the highest frequency component of the signal by an analog-to-digital converter so that the signal can be accurately reproduced.
