An object is experiencing an acceleration of 9.0 m/s? while traveling in a circle at a velocity of
6.2 m/s. What is the radius of its motion?

Answers

Answer:

4.27m

Explanation:

Recall that for uniform rotational motion,

the formula for centripetal acceleration is given as

Centripetal acceleration = ( velocity)² / radius

in our case we are given :

Centripetal acceleration = 9.0 m/s²

velocity = 6.2 m/s

substituting these into the formula:

9.0 = 6.2² / radius

radius = 6.2² / 9.0 = 4.27m

a lower frequency and a shorter wavelength.
a higher frequency and a longer wavelength.
a lower frequency and a longer wavelength.
a higher frequency and a shorter wavelength.

Answers

Answer:

A lower frequency and a longer wavelength is correct on edge 2021

please thank the person above me though, they deserve it.

These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.

How do snakes detect?

With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.

They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

How far could you speed walk in 10 minutes? Use your speed from the 20m test to calculate the answer.

my speed is 13.63.​

Answers

Answer:

Explanation:

Given parameters:

Time for speed walking  = 10min

Speed  = 13.63?

Unknown:

Distance you can speed walk  = ?

Solution:

To solve this problem, we simply apply the velocity - time equation;

 Speed  = [tex]\frac{distance}{time}[/tex]  

 Distance  = speed x time

make sure you speed and time are in the same unit

 Insert the parameters and solve

A projectile is fired at a velocity of 50 m/s straight into the air. What is the velocity of the projectile when the objects displacement is 16 meters and headed downward?

Answers

Answer:

the final velocity of the object is 53.04 m/s.

Explanation:

Given;

initial velocity of the projectile, u = 50 m/s

displacement of the object, d = 16 m

let the final velocity of the object = v

Apply the following kinematic equation to determine the final velocity of the projectile.

v² = u² + 2gd

v² = 50² + (2 x 9.8 x 16)

v² = 2813.6

v = √2813.6

v = 53.04 m/s

Therefore, the final velocity of the object is 53.04 m/s.

How far will a car travel in half an hour at
30 mph?

Answers

15miles, if it is going 30 miles per hour, and you drive for half an hour, you drive 15 miles

Answer:

The car will travel the distance of 15 miles

S= D/T

therefore

D=ST

D = Distance

S = Speed (30 mph)

T = Time (0.5 Hours)

D = 30 * 0.5 = 15

Can an object with acceleration of zero be in motion?

Answers

Answer:

NO

Explanation:

if it has no acceleration then it's not moving

Answer:

Yes when the velocity is constant then the acceleration is said to be zero. Thus an object with 0 acceleration can be in motion.

Let me give you an example to make you more clear

Example:

When  a car is  traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

Given that renewable sources provide only a small percentage of our energy and that nuclear power is so expensive, in your opinion, what can we realistically do to get off fossil fuels as soon as possible?

Answers

Answer:

No getting rid of fossil fuel is not at all possible.

Explanation:

Dream of 100% renewable energy is possible through electrification and use of energy from sun, water and wind. Since, the high production cost of power plant for extracting energy from these sources in itself is a big challenge and hence decarbonized energy in current scenario is not realistic.

Answers

Answer:

Follows are the solution to the given question:

Explanation:

For point a:

[tex]T= 2\pi \sqrt{\frac{m}{k}}\\\\k = \frac{4 \pi^2 m}{T^2}\\\\= \frac{4 \times (3.14)^2 \times 3}{2^2}\\\\=29.578 \ \frac{N}{m}\\\\[/tex]

For Point b:

[tex]E=\frac{1}{2} m a^2 w^2\\\\[/tex]

   [tex]=\frac{1}{2} \times m \times a^2 \times \frac{4\pi^2}{T^2}\\\\=\frac{1}{2} \times 3 \times (0.15)^2 \times \frac{4\times 3.14^2}{2^2}\\\\=0.332 \ J[/tex]

For Point C:

[tex]V_{max}= a w[/tex]

        [tex]= (0.15) \times \frac{2\pi}{T}\\\\= (0.15) \times \frac{2\times 3.14}{2}\\\\=0.471 \frac{m}{s}[/tex]

For point D:

[tex]X= a \sin (wt+ \phi)\\\\0.91=0.15 \sin(\frac{2\pi}{T} \times t+\phi)\\\\0.91=0.15 \sin(\frac{2\times 3.14}{2} \times 0.5+\phi)\\\\0.60 = \sin(3.14 \times 0.5+\phi)\\\\0.60 = \sin(1.57+\phi)\\\\1.57 +\phi =\sin^{-1} 60^{\circ}\\\\1.57 +\phi = 36.86^{\circ}\\\\=35.29^{\circ}\\\\So, X=15 \sin(3.14t+35.29^{\circ}) \ cm[/tex]
