24.89m

Explanation:

Given parameters:

Force on car = 342N

Initial velocity = 0

Time taken = 12s

Mass of the car = 989kg

Unknown:

Distance covered by the car = ?

Solution:

To solve this problem, we simply use one of the appropriates equations of motions.

                     s = ut + \frac{1}{2}at²

   s is the distance

    u is the initial velocity

    t is the time taken

    a is the acceleration of the car.

To find the acceleration;

       Acceleration = \frac{Force }{mass} = \frac{342}{989}

          Acceleration = 0.35m/s²

Inputting the parameters in the equation:

           s = 0 x 12 + \frac{1}{2} x 0.35 x 12² = 24.89m

Problem: Suppose that the rate of flow of water through a fire hose is 21.4 kg/s and the stream of water from the hose moves at
Sloan [31]

Answer:

The force exerted is 318.86 N

Explanation:

The force exerted by such a stream is calculated by multiplying the mass flow rate of water by the velocity of the stream of water.

mass flow rate = 21.4 kg/s

velocity = 14.9 m/s

Force exerted = 21.4 kg/s × 14.9 m/s = 318.86 kgm/s^2 = 318.86 N

Two of the types of infrared light, ir-c and ir-a, are both components of sunlight. their wavelengths range from 3000 to 1,000,0
NikAS [45]
The energy of a light wave is calculated using the formula
E = hc/λ
h is the Planck's constant
c is the speed of light
λ is the wavelength
For the ir-c, the range is
<span>6.63 x 10^-34 (3x10^8) / 3000 = 6.63 x 10 ^-29 J
</span>6.63 x 10^-34 (3x10^8) / 1000000 = 1.99 x 10^-31 J

For the ir-a, the range is
6.63 x 10^-34 (3x10^8) / 700 = 2.84 x 10^-28 J
6.63 x 10^-34 (3x10^8) / 1400 = 1.42 x 10^-28 J

If an exit sign is hanging from the ceiling by three chains each of which has a tension of 15N what is the weight of the sign
kvasek [131]
The weight is 45 N, because the three chains hold the sign, and each contributes 15 N.

Notice that the mass would be the weight/acceleration of gravity, m = 45/9.8 kg. But they ask the weight (force, so Newtons)
