Answer & Explanation:

A fast-moving ball always possesses kinetic energy and to stop it from moving, you have to do the same amount of work i.e. expend the same amount energy in the opposite direction to the ball.

During impact: The amount of work done in stopping the ball (force * distance) = the kinetic energy of the ball

If you hold your hand in a steady position the ball tend to hit and travel within a shorter distance thereby making you be in need of a greater force to stop the ball but if you move your hand in the same direction to the ball, the ball travel within a longer distance thereby reducing the force needed to stop the ball.

Alligators and other reptiles don't use enough metabolic energy to keep their body temperatures constant. they cool off at night
drek231 [11]
To compute for the heat, Q needed to be absorbed or released,  we need

Q = mc\Delta T

where m is the mass of the alligator, \Delta T is the change in temperature, and c is the specific heat of the alligator's body. Plugging in all the information we have,

Q = (300 kg)(3400 kJ/K)(30-25) = 5100000 J

Recall that 1 Watt = 1 J/s, thus time needed to absorb radiation from the sun is

t = \frac{Q}{W}\\ t = 4250 seconds

That means it takes 4250 seconds for the alligator to warm up to be able to absorb the radiation from the sun.

Answer: 4250 seconds

A .183 kg ball is moving 18.8 m/s when it runs into a spring of spring constant 86.9 N/m. How much KE does the ball have when it
Lemur [1.5K]

Answer:

The value is  KE_B  = 20.59 \  J

Explanation:

From the question we are told that

   The mass of the ball is  m  =  183 \  kg

   The initial  speed of the ball is  u  =  18.8 \  m/s

    The spring constant is  k  =  86.9 \ N/m

     The compression distance is  x =  0.520 \ m

Generally the energy stored in the string is mathematically represented as

        E =  \frac{1}{2}  *  k  * x^2

=>     E =  \frac{1}{2}  *  86.9  * 0.520 ^2

=>      E =   11.75 \  J

Generally the kinetic energy of the ball is mathematically represented as

          KE_b  =  \frac{1}{2} * m * u^2

=>      KE_b  =  \frac{1}{2}  *  0.183 * (18.8 )^2

        KE_b  = 32.34 \  J

Generally the KE   the ball have when it has compressed the spring is mathematically represented as

          KE_B  =  KE_b -  E

=>        KE_B  =  32.34 - 11.75

=>        KE_B  = 20.59 \  J

Two identical loudspeakers are driven in phase by a common oscillator at 750 Hz and face each other at a distance of 1.24 m. Loc
Juli2301 [7.4K]

Answer:

0.2286  m,  0.686 m and  1,143 m

therefore we see that there is respect even where the intensity is minimal

Explanation:

Destructive interference to the two speakers is described by the expression

       Δr = (2n +1) λ/2

where r is the distance,  λ the wavelength and n an integer indicating the order of the interference

let's locate the origin on the left speaker

let's find the wavelength with the equation

        v =  λ f

         λ = v / f

we substitute

      Δr = (2n + 1) v / 2f

let's calculate for difference values ​​of n

     Δr = (2n +1) 343/(2 750)

     Δr = (2n + 1) 0.2286

we locate the different values ​​for a minimum of interim

    n     Δr (m)

     0    0.2286

     1     0.686

     2    1,143

therefore we see that there is respect even where the intensity is minimal
