The acceleration due to gravity on the moon is 1. 6 m/s2, about a sixth that of Earth’s. Which accurately describes the weight o
1 answer:
Weight is the force applied on the planet by its mass. The weight of an object is 6 times lighter than that of the earth. Option C is correct.
What is Wight?
- It is the product of the mass and the gravitational acceleration.
- Weight is the force applied on the planet by its mass.
The formula of weight is,
Where,
- weight
- mass
- gravitational acceleration
In the question given here the gravitational acceleration of the moon is 6 times less than that of the earth.
Therefore, the weight of an object is 6 times lighter than that of the earth.

Explanation:
Given
mass of ice cube
inclination
Spring constant
initial compression
Suppose Initially the cube is at the datum and it moves h height after release
So Elastic Potential Energy of Spring will convert to Potential Energy of cube
so final Potential Energy will be
Initial Potential Energy
B.Initially spring is at compression so energy associated with it is its Elastic Potential Energy i.e. 0.125 J
Final Energy
Answer:
164.2°
Explanation:
speed of wind (w) = 45 km/h due south
speed of aircraft (a) = 165 km/h
in what direction (in degrees) should the aircraft head in so as to fly due west?
To get the direction the pilot should fly, we can form a triangle with the data available where
- the direction of the wind (due south) serves as the opposite side
- the direction the pilot would have to fly so he can end up at he west serves as the hypothenuse
- θ is the angle between the direction the pilot would have to fly and the direction the pilot wishes to fly.
- the direction the pilot wishes to fly ( west) will serve as the adjacent side
- all this can be seen from the attached diagram.
now sin θ =
sin θ =
θ = 0.2728
θ = 15.8°
since we are to use the counter-clockwise from east convention our measurement would have to be taken anticlockwise from the east direction, therefore the direction of the aircraft (Ф) = 180-15.8 = 164.2°
