Answer:

D

Explanation:

Scientists don’t watch TV, so scratch that. There is no opinions, do you think people with cancer are looking for someone with an opinion? He.ck no, dude who even uses flashlights we got light switches. Anytime you see scale, you know that’s scientific. So, D is your answer.

Kelly is riding a bicycle, moves with an initial velocity of 5 m/s. Ten seconds later, she is moving at 15 m/s. What is her acce
sladkih [1.3K]

Answer:

her acceleration is 1 m/sec

Explanation:

The following information is given in the question

The initial velocity is 5 m/s

After 10 seconds, she would be moved at 15 m/s

We need to find the acceleration

As we know that

Acceleration = Change in speed ÷ time

Acceleration = (15 - 5) ÷ (10)

= 1 m/sec

Hence, her acceleration is 1 m/sec

The same would be considered

A curve of radius 55.1 m is banked so that a car of mass 1.6 Mg traveling with uniform speed 61 km/hr can round the curve withou
svp [43]

Answer:

θ = 28°

Explanation:

For this exercise We will use the second law and Newton, let's set a System of horizontal and vertical.

X axis

      Fₓ = m a

      Nₓ = m a

Where the acceleration is centripetal

      a = v² / r

The only force that we must decompose is normal, let's use trigonometry

      sin θ = Nₓ / N

      cos θ = N_{y} / N

      Nₓ = N sin θ

      N_{y} = N cos θ

Let's replace

     N sin θ = m v² / r

Y Axis

     N_{y} - W = 0

     N cos θ = mg

Let's divide the two equations of Newton's second law

     Sin θ / cos θ = v² / g r

     tan θ = v² / g r

     θ = tan⁻¹ (v² / g r)

We reduce the speed to the SI system

      v = 61 km / h (1000 m / 1 km) (1h / 3600 s) = 16.94 m / s

Let's calculate

     θ = tan⁻¹ (16.94 2 / (9.8 55.1)

     θ = tan⁻¹ (0.5317)

     θ = 28°

Which are benefits of using nuclear power plants to generate electricity? Check all that apply.
lesya [120]
Below are the benefits <span>of using nuclear power plants to generate electricity:


</span><span>Nuclear power plants use simple power plant designs not vulnerable to human error or natural disasters.
</span>
<span>Nuclear power plants use renewable fuel.
</span>
<span>Nuclear power plants produce a large amount of energy for a small mass of fuel. Nuclear power plants produce no toxic waste products. 
</span><span>
- The outflows of nursery gasses and in this manner the commitment of atomic power plants to an Earth-wide temperature boost is accordingly moderately little. The era of power through atomic vitality lessens the measure of vitality produced from non-renewable energy sources (coal and oil). Less utilization of petroleum products implies bringing down ozone-depleting substance outflows (CO2 and others).

Which can cause blockage of the ear canal, leading to hearing loss? aging disease earwax noise
Ivahew [28]

Explanation:
