<h2>
The gravitational acceleration on planet X is 32.7 m/s²</h2>
Explanation:
The acceleration due to gravity is given by
where G is gravitational constant, M is mass and R is radius.
For earth we have
g = 9.81 m/s²
That is
For planet X we have
Substituting
The gravitational acceleration on planet X is 32.7 m/s²
Answer:
A car is accelerating whenever there is a change in its state of motion. Acceleration also applies to changes in direction. It is important to distinguish between speed and velocity. Acceleration is defined as the rate of change in velocity, rather than speed.
Acceleration =change in velocity/change in time.
So final speed minus initial velocity/time
3.1-v/2=a
The answers are A and D.
Engine oil reacts with rubber, changing its properties and causing it to expand. This will compromise rubber seals in the brake system and lead to a failure.
Answer: Direction
Explanation: A vector is a geometrical representation of physical quantity. It has a particular direction with a specific magnitude. In the geometry of space whether it is two dimensional or three dimensional the vector quantity has a specific direction. Such as a stone is thrown with a velocity in a particular direction.
The path of the stone in three-dimension shows its direction and speed is its magnitude.
Hence, the velocity of stone has two property magnitude mentioned as speed and particular direction. On writing the mathematical expressions for vectors, it is denoted by arrow mark on its top as shown below.
