When we stretch a spring, which two factors affect how much elastic
potential energy is stored in it

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.

Answer:

B.Ionizing radiation is the correct answer.

Explanation:

Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.

It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.

Answer: lonizing radiation

Explanation:

Got it right

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.

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.

Answer:

Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

Answer:

To change.

Explanation:

The Law of Conservation of energy states that energy cannot be destroyed but can only be transformed or converted from one form to another. For example, light energy to heat energy.

When a material absorbs energy from light the energy causes the material to change.

Answer:

The answer is D because when the faults move that is the tectonic plates moving. So earth quakes will be forming when the fault moves.

Answer:

the mass of the central body (earth) and the radius of the orbit affect orbital velocity

Explanation:

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

Answer:

Economic Development is the creation of wealth from which community benefits are realized. It is more than a jobs program, it's an investment in growing your economy and enhancing the prosperity and quality of life for all residents. Economic development means different things to different people.

Answer:

Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )

No

Explanation:

Not all metals stick to magnets. Like aluminum. if you were to stick a magnet on to an aluminum it would fall off.

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]

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

Answer:

the answer is 1500 you multiply the distance and force to get work

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.

Answer:

B

Explanation:

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

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.
