The impact of the type of material of which the slope is made on acceleration

Physics
1 answer:
Pachacha [2.7K]3 years ago
6 0

 The impact of the material type with which the slope is made affects the acceleration. Acceleration will be higher and smoother if the material of the slope surface is smoother as opposed to a texture which is not smooth. Smoother surface allows more acceleration because it will have less friction and resistance. Otherwise the friction will slow the object down for example a grassy ground will have more friction than a well maintained marble floor.

A telephone line has a signal-to-noise ratio of 1000 and a bandwidth of 4 KHz. What is the maximum data rate supported by this l
ivolga24 [154]

Answer:

The maximum data rate supported by this line is 39900 bps

Explanation:

The maximum data rate supported by this line can be obtained using the formula below

c = W*log2(S/N+1)

where;

c is the maximum data rate supported by the line

W is the bandwidth = 4kHz

S/N+1 is the signal to noise ratio = 1001

c = 4*log2(1001)

c = 39868.9 ≅ 39900 bps

Therefore, the maximum data rate supported by this line is 39900 bps

Hii please help i’ll give brainliest if you give a correct answer please please hurry it’s timed
Zina [86]

Answer: The answer is A for sure

Explanation:

That is, there will be no acceleration. If you are sitting at rest in a chair and the upward push of the chair is equal to the downward pull of gravity, you will stay at rest in the chair. ... You now have an unbalanced force acting on you and therefore, according to Newton's First Law, your motion is going to change.

Plz give brainlest :)

An object of mass 6.00 kg falls with an aceleration of 8.00 m/s2. The magnitude of air resitance must be ____ N
allsm [11]
Using Newton's Second Law, we can find the air resistance. We know the net force is equal to mass times acceleration.F_{net} = m*a = (6.00kg)(8.00 \frac{m}{s^2}) = 48N &#10;&#10;F_{g} - F_{d} = 48N&#10;&#10;48N = (6.00kg)(9.81m/s^2) - F_{d} &#10;&#10;F_{d} = 10.86N
