Answer:

Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects.

Explanation:

Gravity is defined as the force of attraction between two objects. It depends on the masses of objects and the distance between them. The gravitational force between two bodies is given by the universal law of gravitation. According to this law, the force of gravity is :

F=G\dfrac{m_1m_2}{d^2}

Where

G is the universal gravitational constant

m₁ and m₂ are masses of two bodies

d is the distance between two bodies

Hence, the correct statement that describes gravity is (b)

Answer:

The answer is Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects.

Explanation:

Gravity is a natural phenomenon by which objects with mass are attracted to each other, mostly observable in the interaction between planets, galaxies and other objects in the universe. It is one of the four fundamental interactions that causes the acceleration experienced by a physical body in the vicinity of an astronomical object. It is also called gravitational interaction or gravitation.

A ball of 0.5kg slows down from 5m/s to 3m/s. Calculate the work done inthe process.
dlinn [17]

Answer:

9.8 Joules (rounded to 2 significant figures)

Explanation:

Work done (J)= Force(N) x distance changed (m)

  • Force= 9.80665 x 0.5kg
  • Force= 4.90332 Newtons

  • Distance changed= 5-3
  • distance changed= 2m/s

--> work done= 4.90332 x 2

work done= 9.8 Joules

Rainbow [258]
Use vector analysis and calculate resultant vector using Pythagoras theorem:
5^2 + 5^2 = 50
Square root of 50 = approx 7.1 km NE
Therefore the answer is D

You are riding in a hot air balloon that, relative to the ground, has a velocity of 6.0 m/s due east. You see a hawk moving dire
charle [14.2K]

Answer:Velocity = 6.325m/s

Directional angle= 18.43°

Explanation:

Using Right angle triangle

Let Velocity of ballon&hawk be VHB represent the height of the triangle.

Let Velocity of balloon angle ground be VBG represent adjacent of the triangle.

Let Velocity of hawk and ground BE VHG represent the hypothesis.

Theta = opp/Adj= VHB/VBG

using pythagorean

VHG= SQRT(VHB^2+VBG^2)

VHG= sqrt(2^2+6^2)

VHG= sqrt(4+36)

VHG= 6.325m/s

Tan theta= 2/6

Tan theta =0.3333

Tan^-1 0.3333=18.43°
