Answer:

D. the distance and direction to the water fountain

Explanation:

To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.

This quantity is known as the displacement.

Displacement is a vector quantity with both magnitude and direction.
To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
The direction attribute distinguishes distance from displacement
The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.

timama [110]

Answer:

90 meters

Explanation:

Given:

x₀ = 0 m

v₀ = 0 m/s

v = 30 m/s

t = 6 s

Find:

x = x₀ + ½ (v + v₀)t

x = 0 + ½ (30 + 0)(6)

x = 90

The car travels 90 meters.

The free-fall acceleration at the surface of planet 1 is 26 m/s^2 . The radius and the mass of planet 2 are twice those of plane

valkas [14]

Answer:

13 m/s^2

Explanation:

The acceleration of gravity near the surface of a planet is:

g = MG / R^2

For planet 1, g = 26 m/s^2.

The gravity on planet 2 in terms of the mass and radius of planet 1 is:

g = (2M)G / (2R^2)

g = 1/2 MG / R^2

Since MG/R^2 = 26 m/s^2, then:

g = 13 m/s^2

All charged objects exert a force that can cause other charges to move. What is the force that

pashok25 [27]

Answer:

exerts force

Explanation:

The accumulation of excess electric charge on an object is called static electricity. ... An electric field surrounds every electric charge and exerts the force that causes other electric charges to attract or repel. Electric fields are represented by arrows showing the electric field would make a positive charge move.
