Answer:

1,896,770,400J

Explanation:

The equation to find Kinetic Energy (KE) is

KE = \frac{1}{2} m v^{2}

You are given

m = 480000kg

v = 88.9m/s

Substitute the values into the equation and solve for KE

KE = \frac{1}{2} m v^{2}

KE = \frac{1}{2} * 480000 * 88.9^{2}

KE = 1,896,770,400 Joules(J)

the electric field midway between two equal but opposite point charges is 573 n/c , and the distance between the charges is 16.0
saveliy_v [14]

The electric potential  between the two charges is 91.68 V.

<h3>Electric potential between the two charges</h3>

The electric potential  between the two charges is calculated as follows;

V = Ed

where;

  • V is electric potential
  • E is electric field
  • d is the distance of the charge

Substitute the given parameters and solve for electric potential,

V = 573 N/c x 0.16 m

V = 91.68 V

Thus, the electric potential  between the two charges is 91.68 V.

HACTEHA [7]

Answer:

C. Sturdy stems

Explanation:

Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.
